Problems with cooling pc

Hi, i have recently purchased a temp desktop computer for a a few months till i can buy a new one, the only issue i have with it is that it is really loud fan wise, and i think that may be because it is a noisy fan but also i dont think it can cope with the room im in, the room is a office room so it has no windows or air coming in regulary, its not usually that hot but i dont know if they computer needs air also is there any other (not looking to spend a great deal will spend some though as it will only be sold on once i buy mine) way to cool the PC down apart from putting it in a different room (as that isnt a option )

The specs that i know are:

Windows 7 32bit proffesional,
Dual Core 1.87 ghz,
Packard Bell Imedia pc (forgot number if needed i have it written somwhere),
1.5 GB Ram but i do have some spare 1gb sticks i will chage with it to make it 2 GB next time i open it,
NVIDIA GeForce 7300 SE/7200 GS (dont know speed but dxdiag says this Approx total mem, 533mb which i dont understand and think its wrong).

Thanks for helping.


EDIT: i forgot to mention the most important thing, the comp is on for most of the day usually like 12-16 hours i turn it off most nights though not all and i do switch if off somtimes during the day for 30 min breaks not sure if it helps it but im worried for the comp

well lets see...

start off by i'ding your cpu:

the next step would be to check whats the cpu temp.

i use this one (note that different programs give different readings):

after doing those 2 steps, google your cpu model with temperature and look into some forums seeing whats the avg. heat i C people are getting with that cpu. anyhow as a general law (this is all imo not real numbers):

idle: under 30 =very good
idle: under 45 =good
idle: over 60= bad

your best tool to use to get the heat problem solved would be to get a decent heat-sink , they cost anywhere from 10$ to 100$+. here:

this what i got atm. a big ass heatsink+active air cooling. since your using dual core, your Socket should be the lga 775. just make sure what ever you get fit your socket.


beside getting that u can get also a better fan for your case, something like this:

also, its is important to know how air circulation inside the case itself is. make sure the case is clean and the fans also. if there are many lose wires inside try to bundle then as one. make sure that your rear case fan is to close the the wall.

hope this helps.

Ok i researched around for my processor there wasent a lot of post about it but the lowest idle temp was 40 and the highest was 65, from what i worked out most people had between 50-55, mine is currently at 49-53 so if i was to purchase a heat-sink i think it should be ok, i had a look inside when i bought it air flow was good, but after a week there was a very thin layer of dust on the fan on the inside, is this really bad because it will probs be building up in that case right?

Btw thanks so much for your help

what do you have for fans in your case? if it came with an 80mm fan in the back and nothing else, consider adding a 120mm fan (usually spins slower, but moves more air and is quieter) and perhaps another 120mm fan in the front to draw cool air in.

what he said, for heat sink i can say that without one my cpu temp was close to high 60C with the box heatsink+fan. with my current one im at 29 31 at idle and never pass the 50 even with full stress test.

a thin layer of dust is nothing to worry about, it doesn't lock like this is what causing the heat problem.

fYI: u need to KNOW how to install a heat sink! this is very important, you may FRY the cpu is done wrong.hmm here:

just hes doing wrongly btw, best way to apply thermal paste is to use any kind plastic card in order cover the whole cpu with a very thin layer (too much paste= same as no paste.)

Forget the heatsink stuff that's just all red-herring in your case.

Things to check...

1. Where is the base unit located - if it's in a corner or has it's back pushed up against a wall then your venting of hot air will be blocked.

2. If you have multiple fans in the case make sure you have a directional flow through the case - e.g. front to back - front fans suck in, rear fans blow out. Don't expect PC manufacturers to get this right either, a fan installed backwards is a common thing.

3. Make sure you keep fan grills clear of dust - wet wipes are good for this.

4. Get a PCI slot exhaust style fan for about $5. These blow huge volumes of air out of the back of your PC and are very quiet.

Hope this gives you a few ideas.

You seem to be implying that the noise of the fans is somehow connected to the temperature, but I doubt that that is the case.
Firstly, the room that the computer is in doesn't matter unless the temperature in the room is way above normal or way above the temperature in other rooms. Computers don't need "fresh" air, just "room temperature" air. (It doesn't even need to be "breathable" air.)
A lot of cheapie computers use low cost fans. Those fans tend to be noisy. You should be able to replace many of the fans with quieter models.
-- BTW - is this a used computer? If it's used, some of the fans could simply be going bad. The bearings wear out and become very noisey.
Start by opening the computer up and, while it's running, try to determine which fans are causing the most noise. The fans are not very powerful, so it's ok to stop them momentarily to check the noise. (try not to ram your fingers into the blades though - no perma damage, but it can smart.)
If it's the cpu cooler, the fan is usually removable, if you don't want the hassle of replacing the whole cooler assy.
If it's a case fan, replace it with a quieter model and/or larger model (if you have the space & mounting holes). As Elder said, the larger fans usually turn slower (and quieter) to move the same amount of air.
Chipset or video card fan - you can get various small fans at local shops or online.
Power supply fan - These fans are replaceable, but usually require you to disassemble the whole PS and use a solder iron. Otherwise you need to replace the whole power supply - which could be cheap or costly depending....

Open up your case and check the dust as well. Recently cleaned up a friend's machine and it went from 61C to 32C idle ( it really had a whole family of dust bunnies )

If its only a temperary CPU then just take the side panel off and put a regular 2' x 2' box fan up against it. Yeah its not the best thing in the world but it is a temperary fix for a temperary CPU.

Even if you reverse the fan (i.e face it away from the CPU but still up against the side) it will still move alot of air over the insides as if pulls air through.

Just doing this will save the time and effort of buying a fan and connecting it all up. Plus if you are in a room with no air flow, well guess what, now you have air flow for the entire room not just the CPU.
