CPU remains overheated...........tried many options!!!!!.

R

P5B- dlx with C2D 1.86 running with stock intel fan, 400 watts Zebronics PSU.

Got a new comp a month back, could not over clock my due to rising temp. My case is frontech royal, 2 front fan, 2 rear fan, 1 side fan.*www.frontechonline.com/admin/image/cabinets/1556.jpg

I today opened the mobo & saw that the heat sink was not fitted properly (nehru place guys suck) I further saw that the mobo is having 4 mm sponge laid between the case & mobo , I called up the guy who fitted all my comp , he said that the mobo was getting "short' so he used it for insulation, & it wont harm it any way.

But I guess it will not let the heat transfer on the other side plus if for some reason the mobo is "shorting" with case I better get that replaced, its a month old mobo & it should not have such problem.

I fitted 2 front fans & 1 rear fan & one in PSU but even then my temp are quite high. IN BIOS it show that fans are not fitted where as I have at least 1 fan connected on mobo at Ch_fan2 on P5B-dlx mobo, (2 are connected from the power supply)how do enable that in BIOS?

I changed the comp location to a different room right next to window but that did not help much, it was thenlowered to 48°, the ambient temp of the room is 21° yet the cpu is ranging from 52°-56° on ideal, if I use it heavily then it goes 60-67°, I event took the cabinet side covers to let the air in from all sides, that also did not get my temp below 48°.

I am also having warning every 2 mins, of Vcore voltage from Asus PC probe II that the Vcore voltage is high, its ranging in 1.14v-1.30V, normally it remains 1.18v,I get warning only when it goes above 1.28v & below 1.16v

Is this a false warning bcoz the in the BIOS the Vcore is set to auto & the mobo is changing it automatically?

I have read the overheating thread & did not get any answers to my problem.

What is causing the high temp in my case?
What can I now do to lower my CPU temp ideal 45°?
Where can I get in delhi artic silver 5?,
I got some local thermal paste for Rs 20/- but hesitate to apply that it might be conductive to electric current.

Need some direction to get this under control as in delhi summers it will fry at 40-45° ambient temp.

yea... get arctic silver 5... in mumbai it costs abt 580 for a small tube....
the normal cheap paste isnt too good...

R

any contact no of a dealer which can courier? Quite strange that delhi is hotter than mumbai yet no one has AS5 here in delhi.
__________
OK solved the Vcore warning problem from reading on asus forum.

"Go into Probe 2 and change the alert threshold to something more than 10%. The VCore voltage constantly moves between 1.08v to 1.34v on all C2D CPUs when settings are kept on Auto. This is perfectly normal."

moved the setting to 20% & red warning gone.

Y

yup apply arctic silver 5 or even arctic ceramique will do ..

keep those 2 front and 1 side fan as intake fans .. and 2 rear fans in the back as outlet ..
and properly fit ur heatsink on cpu .. and see what happens ..

Thats exactly how I have the fans fitted but no artic silver here in delhi.

Make sure u disable "Automatic QFan Control" in the bios .. or any target temp that u might have set ...

Also , the voltage can fluctuate when set to auto .. for a CPU running at stock .. i'd recommend u to try some permanent voltage between 1.2 and 1.25 ... u don't need anything more for a C2D at stock .. i'm running mine oc'ed at 3.02 GHz with only 1.25V

..

R

I have not set any target temp & Qfan is disabled & not installed, voltage problem is solved.
I will try removing the sponge & take the mobo out & use barebone PC in open air keeping it on a non conductive surface &then monitor the temp.

ranjan dude first of all get rid of that punk A$$ Zebronics PSU. & get a better one.
i cant believe it, you bought a Zebronics PSU for a ASUS P5B Dlx Wifi

& if you got any Overclocking plans, dont do it with the Zebronics.

& i've a doubt, if the m/b is shorting, then is it a problem with m/b or PSU+earthing or cabinet+PSU+earthing???

First of all delhi or North India for that matter is shiiit. Even if they have arctic silver, they will mix it with something & sell you the local thermal paint at cost of original.

Motherboard shorting with cabinet?? That was something 5 years back. Now that sheet is not required to be placed. Your outdated assembler will screw ur system. Earthing provisions have now been built in the motherboards [mounting holes].

Hope that your mobo is not mounted directly instead it uses brass mounting studs underneath mobo. Every cabinet including Zebronics have that provisions. You can have a look at Antec Super Lanboy [aluminium cabinet], Al is better in dissipating heat.

R

It seems that the guy who assembled my comp has screwed up in a big way, I remember that there were special screws with the mobo but the board is not having any of those screws at all, instead he used local screw all different sizes.

Tomorrow I am going to disassemble it & mount it my self & check the earthing problem too.

I could not find any good power supply here in nehru place, here we discuss coolermaster / powersafe etc but these things are not easily available in shops.

I have no plans of overclocking till I get this temp under control.

__________

next day updated

I opened the mobo & got to know some shocking facts, before that see the images which I want to ensure that heat sink was seated fine.
*img120.imageshack.us/img120/5025/heatsinkmountedwl9.th.jpg

The rear side mounted confirms the same
*img120.imageshack.us/img120/3900/heatsinkrq2.th.jpg

Then I checked further & found that the center is pushed down either due to Heatsink weight or design defect. Is that normal happening????
*img120.imageshack.us/img120/3923/mobotiltedtd4.th.jpg

This definitely will short with the body when its mounted, bcoz the center part is dugged 3-4mm deeper

I then opened the heatsink to check the thermal paste, hope this is fine too.
*img120.imageshack.us/img120/4774/thermalpastenl3.th.jpg

Then I gave a serious thought & remember that the mobo or the cabinet had some insulated mounts which were suppose to be fitted below the mobo & they were missing & due to that the mobo was tilted right side 6 mm to one side , bcoz the back (left) panel was lifted to fit within the USB slots, in that case its bound to touch the metal body & create shot circuit .................................this duffer who fitted my comp insulated it with 5mm sponge & that was trapping the heat badly.

I made a local jugad (since its sunday) with double sided tape & made a insulated mount which can lift the mobo so it does not touch the body & removed that sponge & booted in bios to watch the hardware temp.

I did that & Voila..................................!!!!!!! ............I booted successfully for the 1st time with 43° ideal temp & now running at overclocked 2.3Ghz.with 50° ideal temp.
*img120.imageshack.us/img120/5052/0007mh6.th.jpg

Now tomorrow 1st thing I go & kick the guys ass who did that blunder with the fitting & get my insulated 6mm mounts to get the board running as it should have been from the 1st day.

ALL HEATING PROBLEMS BE SOLVED THEN.

Thanks guys for helping out it was a real nightmare for me last few days sorting this temp issue.

i'm glad your problem's solved

btw these are the BRASS Mounts which were provided with Zebronics AntiBiotic cabinet

*img245.imageshack.us/img245/4702/dsc04381anp1.th.jpg -- *img412.imageshack.us/img412/121/dsc04380aah5.th.jpg

Zebronics povides lots of Screws, these Brass Mounts...

So ask your Assembler for those.

R

Yes these were there in a packet which he should have used to mount the mobo, but he did not .....................I am going to fire him up tomorrow 1st thing in the morning.

Wow! Great troubleshooting dude!! If you hadn't detected this, your mobo and proccy would have been fried in a month for sure. Blast that guy and get something for compensation, if not, don't think twice to thrash him

R

Sure it would have fried as the summer approaches here in delhi the ambient temp in the room goes 38-40°, in that case it would start giving me problem....................gud that I got this sorted out.
Tomorrow I will buy some extra mounts & fit that in the cabinet.

Get those brass studs out of his G and teach him how to install and then show him on your motherboard [arround the mounting holes] the provision in circuit itself for earthing. If you mount all the studs & screws, you don't need any two side tape etc.

So many studs & screws come with Zebronics cabinets. Ask him to explain, why did he put that sponge sheet. It is strange that such ignorant people get into this business of assembling. This happens only in Delhi.

R

I finally got the original screws directly from the company (frontech)as this bugger had lost it & kept on saying that these screw do not work with ur mobo.

I then fitted the mobo yesterday & now its 6mm away from the cabinet.
My heat problem is partly solved but I am still running high by 8-10° @ 62° overclocked at 450 FSB

What else could be wrong as I am told that the ideal temp even overclocked should be within 50-52°.

@s18000rpm
Zebronics 400W PSU is not that bad. Its working fine for me. This sites reccomends at least a 500 to 550W one for my PC but Zeb 400W is fine at even full load.

R

After trying many options, I called up intel/asus & they both have asked to check the respective cpu/mobo to ensure that they are fine , if not then they will replace, but this will take at least 4 days for them to revert back.

Intel has asked me to get the cpu to check on another intel board & asus will self test on its testing bench.

hope they can find some fault & replace the faulty unit.

R

last few days update is that the Vendor Comnet vision tell me that I need to have a better power supply since 7600GT needs that & they say that CPU heating is due to low wattage of my so called Zebronics 400 watt smps. So before taking up the matter with Intel /asus they want to testthis with the following.

They have suggested me the following.
*www.antec.com/images/400/TX1050B_inside.jpg
Antec Performance TX 1088B
*www.antec.com/us/productDetails.php?ProdID=61050#

& the following power supply to choose from.
Earth watts 500
*www.antec.com/images/160/earthwatts_q.jpg
*www.antec.com/us/productDetails.php?ProdID=27500#

or
Neo HE 500 watt
*www.antec.com/images/160/NeoHe_q_sli.jpg
*www.antec.com/us/productDetails.php?ProdID=28500

What do u guys think of this combination, will it solve my cpu heating problem?
Is it really due to low watts of my SMPS that cpu gets heated up?

Which one should I buy for my system (config is in my signature)

R

Hi sam, they are arranging thsi at their own cost , if this solves he problem only then I will buy it, & yes its quite overpriced.

Last few days I tried searching for powersafe, but no one knows about this brand in Nehru place. I dont know if some store in mumbai can ship it to me or not, NP is a useless market (biggest computer market they claim) & u dont get what u want, mostly they want u to buy what they want to sell.
Even Zebronics have some high end SMPS, but again the same story ..........u dont get what u want in nehru place.

[off topic]
Sam dude, pls clear/delete msgs. from your PM inbox.

i tried to PM you several times.
[/off topic]

R

I wrote to asus & this is what they replied.

The temperature is normal. For CPU temperature, if it is below 75C degree, it is normal. If the motherboard temperature is below 60C degree, it is normal. Please don't worry about the temperature.

If you have any problem, please refer FAQ(Frequently Asked Questions) or contact us again. We will try our best to help you.

I really dont know what else could be done? most of the users report 35-45° ideal temp so compared to that mine is surely high & if I overclock it reaches 74°C on full load, which is not good for 24x7 usage.
--------------------
I still wonder how a better power supply will solve this issue?
What does PSU have to do with CPU overheating, is there any connection?
It will take 10 days for the dealer to get the antec PSU & I am getting a feeling it will not solve the problem

if possible try to get a PSU from any of your Friends & test.

or does any friend of yours have similar config, so that you can test your Processor/PSU on theirs' & vice-versa

R

Sam I got finally today Zebronics Peace cabinet & Zeb 500 watt platinum power supply & eagerly changed the mobo & hdd to the new caby...................................but but but my temp still remain the same 50-54 ideal, no over clocking at all & at fullload (No OC applied) TAT load test makes it 74-76C, that too high.
This PSU gets mounted upside down so the big fan air flow is downwards, I am not sure ifthats ok or not, I feel it should be upwards.
*zebronics.net/images/power/zeb-500w-2led-b.jpg

If I OC then it will go beyong 60 ideal & at full load 80-85C,

I also tested another graphic card just in case that might be the cause, but no chnage in ideal temp.

Its surely either the mobo or the intel heat sink seems to be faulty, though my test images show it looks fine.

Now the only 2 things left are intel HSF & asus mobo.................cant think of anything else.

about PSU
i think thats the correct position :wink:

, its a Bling-Bling PSU

, so how wud you show-off the LED fan of PSU

R

Sam, Ur temp shows 56C ideal when over clocked but mine shows 52-54C non overclocked, let me try tomorrow same over clocking then I post back the findings.

BTW r u back in delhi ?

i think thats the correct position , its a Bling-Bling PSU , so how wud you show-off the LED fan of PSU

What is this bling bling, never heard of this I just got it bcoz I wanted to try any thing higher that 400 watt to rule out that low wattage may be creating heating problems.

bling bling

a term for shiny accesories,such as chrome wheels,diamonds,etc

i refered it as Bling-Bling b'cos it has the LED fan

, so flashy kind of thing

, ...Bling-Bling

R

hahhaha.....I was wondering what else could that mean..nice keywording ............now I will bling bling tomorrowwhen I OC my system.

@ranjan2001
Can u say ur GPU temps at max load while playin a real heavy game like the Rainbow Six: Vegas?
WOW Sam ...gr8 overclocking....3.3 from 1.86!!!!
An how much did ya pay for that 500W platinum. me too have ordered the same PSU nd the dealer says itll take a week.

R

Arvind
I dont game at all, so GPU don't get so much heated up, I got that XFX card bcoz of 2 dvi port & higher resolution dual display possibility in near future, though I will check the GPU temp too tomorrow.

I got zeb 500 PSU for 2400 +4% vat

yes you are right Mr.Sam.

how many other guys are in this Bling-Bling Club,

, other than us three

& not only PSU, ranjan has got "Zebronics Peace " too, fully fledged Bling Bling PC

like Bling Bling H2O cooling.
that wud be a kick A$$ PC :twisted:

Im gonne add moe Bling Bling by adding some LEDs inside sleeving tube. Ive tested them outside the cabby nd Thinking of adding a 4W CFL Lamp for more bling bling. Do u have any idea how to make a CFL Lamp light cool by covering the lamp with some colourful stuffs??
Is there any harm on sticking coloured insulation tape over the tube(CFL tube)? CFL tubes dun heat up(not the adapter) so i think its OK?

Ive Antibiotic cabby, so more Bling Bling with the lamp .

R

Sam, I tried OC & now running 450FSB stable with Vcore set manully to 1.25V, & surprisingly the temp are now same as u reported around 56°C ideal & on load test with TAT reaches 79-81°, so I guess I can leave my worry for a while& get back to OC further.

2 problems I am facing with peace cabinet is that the power down switch is working strangely when I shut down via start menu the comp shuts down but restart again, I check the switches 3 times that the power is plugged in power & reset is plugged in reset......................am I doing something wrong?

The big side fan is quite noisy in my case when it starts its sound can be heard even outside the room is that normal?

R

Sorry Sam,
I should not have posted this here.

R

Sam, we discuss heating here & OC we discuss there.

Today Intel provided the instruction to the vendor & he cleaned up the heat sink & applied Intel thermal grease, that partly solved the problem & now NON-OCed CPU ideal temp is around 40-42°C & on 100% load using TAT it goes 60-62°C, but in my case this happens with big side fan running including all 4 fans too.

My present room temp is 27-29°C
----------------------------------------
Update
Seeing your posted shots earlier now I have the same temp & OC settings, so I think we have solved the problem of heat.

I Oced to 472 & my ideal is 55°C & on 100% TAT load it reaches 80°C, same as you had, Orthos load test does not make the temp go that high, it remains 66-71° only.

Great ................ for the 1st time I am seeing 42° on this board non OC..............I am partly releived.

My hunt for cooling sloution continues.......then I will try stretching my C2D to 3.6 , an 100% Ocing......

Did you not get the cooler master water cooler in bangalore, contact details were posted in another thread.

Last 3-4 days even delhi is hotter its now 30°C ambient & it will upswing for next 2-3 months.

I mailed to www.sidewindercomputers.com & Got a reply that they will ship to India the cooling fan solution. If you are intrested & back in delhi then I may order 2 of them so we save shipping at least.

Though I have to decide which one I buy so it can fit well in the peace cabby.

R

I am thinking
Scythe NINJA PLUS Rev.B 6 Heat Pipes CPU Cooler
or
Scythe INFINITY 5-Heat Pipes CPU Cooler
or
Arctic Cooling Freezer 7 Pro

With AS5 applied & these coolers in peace cabby 8-10° it should go lower, so in peak summer we can hover around 50-55 OCed.

R

21% is the duty & US$20 will be the shipping charges.
So 1750 + 21%+levies (Rs 400)=2250
So the total cost would land up around 2250+ 1000 for shipping, not bad at all............surely expensive but hey OC gives you so much extra power too.

R

sam9s said:
When r u planning to get this imported.

hahhah......................as soon as ambient touches 38-40 we woud need this for sure else no OCing.

Its been raining & hail stroming in delhi so the temp is around 26-30°C as of now but its just a matter of few days, In april it will surely go up.

I have no experience with water cooler but if its available for 3500/- surely we can look into that too, SMC delhi has one model of cooler master quoted me 5.5K for the same.

R

With Ninja we surely need to remove the big side fan from the peace cabby, since ninja is 15cm in height, & with optional fan another 2cm to add
*www.scythe-usa.com/product/cpu/026/images/ninja-dime.JPG
*hardware.gamershell.com/images/reviews/scythe_ninja/scythe_install3.jpg

I have not measured the case but base on my estimate that it wont fit with side panel fan.

NINJA review here

*hardware.gamershell.com/articles/scythe_ninja_cpu_cooler_review/
__________
UPDATEI just measured the width its exactly 16.5mm space from mobo base to the cabby door so it would fit in, but the side fan from the cabby needs to be removed.

Hey sam9s!
Why don't you try to find CORSAIR water cooling kit. They do give very good result in terms of bring down the temperature.
See review of one of its product "COOL WATER" here *www.legitreviews.com/article.php?aid=168
and of "NAUTILUS 500" over here *www.legitreviews.com/article/302/1/

Both their price is around $155-160. *www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1221697

R

John,
The idea of OC is to make best use of stock speed, if one needs to buy a special case or special heatsink fan for $155/- isn't it better to get higher processor?

I use 6300 half the cost of 6600, now if I have to spend that amount to run 6300 at OC speed I rather buy 6600 or 6700.

E6300 doesn;t cost half of the E6600 .. the price diff. is around 5k's .. and well worth it ..

R

Well when I bought it in jan 1st week, the difference was nearly half, 6300 was around 8200/- & 6600 was quoted around 14000/- & not easily available.

I discussed this here & decided that since 6300 has good Oc capability its better to save money & invest in gud ram & PSU.

ranjan2001

Rightly said but to achieve good OC one must also use good cooling solution. Your selection of NINJA heatsink is good but I thought you guys really are looking for water cooling so I suggested the CORSAIR thingy.
Arctic Cooling's thermal solution are also good and costs less then others, maybe you could look at their products.
I myself am using ARCTIC COOLING FREEZER 64 PRO for my X2 3800+ and have overclocked it from 2GHz to 2.6GHz with idle being 38C and load of 45C.

Artic FREEZER 64 PRO is also on our choice list but ninja seems to out perform artic, thats what I have found reading many reviews.

I have no inclination towards water cooling but Sam has been discussing this with fellow OC guys. More over I feel peace cabby cannot take water cooling eaisily, as there is no front open vent for the water cooler radiator.

Good luck guys.........better get that ninja and overclock and do post the results here.

R

Hi Sam, I measured it & it would "just" fit in leaving few mm from the case, we surely need to remove the side fan & place it somewhere else.

We also can mod the case (clear side can be removed & be screwed from the out side with 1-2 cm of packing) that will do the job perfectly.

I inquired from sidewinders.com & performance-pc.com, both ship to India. Once u r back in delhi we discuss this & order accordingly.
