Need to buy a cpu heat sync

Which cabinet u have?

And its heatsink

CM Hyper 212 Evo @2.1k

I use same processor and this one is keeping Idle temp at 38 and load (Prime) at 52 deg which were earlier like your temps and VERY quiet. I cant hear its sound even if I keep side panel open.

and comes along with nice Thermal Paste also so no need to buy separate.

If your budget is low you should go for a hyper212 evo. But first you need to specify your budget.

dude i have a CM 431 elite
and my budget would be a maximum of 3k
i need to knw something
before i upgraded my comp i didnt hv any heating issues
i have 2* HD 6750 (HIS)
Gigabyte 790 Xta UD4
now it heats up a lot
please can anyone see what the problem can be?????

From your previous posts I guess you are having 955BE. Well I have same proccy. Check for TIM. I am using Arctic Silver 5 and CM Hyper EVO and proccy clocked at 3.5GHz. Temps are not crossing 40 in general use.

yea it is a 955 be
for how long have u been using it
and i just started facing this problem recently
earlier it wasnt there
can it be something other than just heatsink

Go for hyper evo at 2.2k and get a good TIM. Also you can add a cabinet fan for extra cooling.

got 3 cpu fans already
do i still need more fans
btw wat should be the inlet to outlet ratio ??

I think you mean Case fans.

3 are usually enough but check directivity as they should complement each other and not vice versa.

this is in idle cond just after switching on the PC
what should be the voltage of CPU coz it is now set to 1.45V

you really need a CPU cooler. those are quite high temperatures. also check if the heat-sink is properly seated. if you have 3 fans at-least 2 should be intake and 1 rear exhaust.

From those temps either your Heatsink is not fitted properly or your Thermal Paste is dried up or may be both.

I am using my system from almost 2 and half months.

If your budget is 3K then grab the Corsair A50 Direct Heatpipe Cooler at 2.7K from SMCINTERNATIONAL. It has real good performance and actually very close to Noctuara U12P.
