well i have a blower but it doesn't cleans the heatsink
and my cabby has 2 80 mm fans which are equivalent to **** what are the cheapest and best alternatives to keep my cabby cool and dust free

For cooling you can get better and bigger fans from cooler master etc.
For dust free there arent much options other than keeping most of the non-essential openings of case closed(not the fan vents ofcourse) and cleaning it regularly..like on weekends o so.
You can use canned air for quick cleaning of heatsinks or soft dry brush but that would require greater care.

when cleaning the cooler, check the area between fan and the heatsink.

How much will.the 120 mm fans cost. And i can attach only one 120mm fan the other one has to be 80 mm fan and how much will an air can cost. Any other method of making cabby cool

Here:

Many options exist.

1. Vacuum cleaner blowing in a low setting onto the computer box placed in a corner on the terrace/balcony.

2. Electronics cleaning putty.

3. Dismantle and clean (this may rule out some parts due to the warranty stickers etc, and also because some times it is not easy for everyone to separate the electronic/electrical parts from the others since many of them are glued in place by the maker etc.)

i. The electronic parts in IPA with lint free cloth or cotton.
ii. Plastic parts in soap or detergent solution, or Vanish/Easy Off Bang. I didn't use Harpic because it has 10% HCl.
iii. Metal parts similar to plastic parts but dry them immediately in Sun.
Since the method 3 takes a lot of time and labour, even though it cleans the gear best, things look dirty within hours.
Also, due to the washing, some of the lubrication applied during manufacturing may also get washed.

The electronic parts may be cleaned in distilled water and/or distilled water+soap using a piece of cloth/brush/cotton, but it is quite risky since even if a small amount of water remains unevaporated, then it is almost a certain bye-bye to the hardware.

Ok now i meed to buy. Some fans to install in my cabinet where can i get them at reasonable prices and will they be able to bring temps down

While fitting the fans in the cabby make sure there Air flow directions assist each other.

For CM Fans the Directions are there on the Fan Case but for Sunbeam etc they are not so its harder for a Non tech guy to judge the Direction.

Not a big deal about the direction of airflow - it's simple.

The blades are concave to the side the air flows to. Example - look up at the ceiling fan.
The fan itself has an X shaped frame on the side of air flow.

The first point is a bit confusing, and easier way, have a look at your kitchen exhaust fan, it can give you a clear idea on the direction of flow...Notice the barebones of fan are *inside* of your kitchen, and the other side is pointing outside

In this fan, it's clear that the air will flow to the REAR of the picture, that is, inside the plane of the paper or forum or whatever

Use some common sense and you're good to go

No confusion

. Convex side == from, Concave side == to. Usually they make the X frame on the concave side.

^^^ I figured that out *after* posting my comment lol

Gave it a close look after posting and found out you were right

screw that, every fan has 2 arrows on its side, showing :
1. airflow direction
2. direction in which the blades turn

They do have, but one has to look for it like a needle in a haystack.

About the direction of rotation, it is anti-clockwise when the convex is facing the viewer. To make sense of it, that is the only way the blades can paddle the air for circulation on the concave side.

yeah, they are usually covered by the wires, or in odd places

Ohk i figured out that my cabby can have 1 120mm fan and 1 80mm fan not more than that so now what to do ...shud i buy a 120 mm fan or do some diy project for cabinet cooling ....

fr cooling, try throwing the air out as it will avoid dust, use the 120 mm for sucking and 80 mm for throwing.. That must do and to find the direction of airflow..

Just check out from where the blades can be grasping the air and from where they can throw it out, the uplifted side will grasp.. Practical knowledge.. You can also manually spin the baldes..
