(moderation:
Recently I've seen quite a few posts on various BOINC forums asking about what to do to get a machine running cool again. So... Being a PC builder myself, I've put together a few words on the subject which can be found on my SETI/BOINC page here
Hope this helps

Sorry about that Thierry... I just did a copy and paste on the text and banded the same message on CPDN, E@H, SETI & LHC. Pointing the article back to a common resource seemed to be the best way of doing it so as to save me typing... Thanks for highlighting the error... Seems like I have to go about all the projects doing the same... Doesn't it!!
This IP sometimes changes, hence the re-director, so I'll correct the error in the link here.
LOL
Thanks again for pointing this out.

I notice you don't mention the liquid cooled systems that are available. Have you any experience to relate concerning liquid cooled systems for CPU's?

I have a liquid cooled FX-53 with a 256MB ATI x800 Pro (vid card also liquid cooled) and sit at 36C under full load. I sometimes hit 38C during the summer months.

I've just had a quick look at your suggestions and you seem to have overlooked one of the more important things to do if you want to run the cpu as cool as possible.
You correctly highlight the importance of good ventilation to keep the internal case temperature as cool as possible. This is because blowing hot air through a heat sink is not as effective as blowing cool air. However if you do have nice cool air inside your case, you can achieve a significant further reduction by blowing it faster. It is a very simple matter to replace the standard fan on the cpu heatsink with one that has a higher throughput. The only sacrifice is increased noise levels if you go to a fan that is too fast but I've always been able to get an improvement without a significant noise increase by using a fan with a larger diameter and a low to medium speed that shifts more air than the standard fan. These will attach quite easily with a suitable adapter.
Another point with case cooling. You mention having a couple of inlet fans at the front and exhaust fans at the rear. I believe it is important not to have too many inlet fans since if there is a positive pressure inside the case the air will tend to leak out at multiple points (probably near the front) and will not contribute to the cooling action. I think that having sufficient fan power at the rear to exhaust the hot air and allow the cool external air to leak in wherever it wants to, is probably the best solution. Many cases have lots of vents near the bottom front and bottom sides which will allow plenty of air to enter without trying to force it in. A good, correctly placed exhaust fan getting rid of the hot air at the top rear is the most important consideration.
