Silence

Finding a silent computer today is possible but then they aren't usually that well cooled. Or if they are well cooled they sound like a vacuumcleaner... Or if you have lots of money, get a zalman TNN fanless case with heatpipes. Or maybe even watercooling but that's usually expensive and quite a few people don't like to have water in their computers for obvious reasons. I have done watercooling but it wasn't that much better than air so after that I've stayed with aircooling.

What I have now is a thermalright xp-90 heatpipe heatsink for the cpu. A thermalright v-1 for the gpu. Four 19db glacialtech 120 mm fans plus a 19db glacialtech 80mm fan for the gpu. I have a hole cut up in the side of the case right in front of the cpu and 2 of the 120 mm fans ducted into the cpu cooler. One in the psu and the last one cooling the hdds. The top part of the v-1 cooler has the 80 mm fan and I have a hole cut out in the duct so some of the outside air goes into the gpu too. And they are all blowing into the case, but I do have a 120 mm hole in the back of the case where all the air can get out again.

All these fans are low pressure fans since I've found out that one doesn't need high pressure fans in computers unless the cases are very small or very cluttered or if the cpu cooler need very high pressure to perform which most heatsinks don't need today. My venice core athlon 64 3000+ oc:ed to 2.6 Ghz idle at 31 and full load is 42 with prime95 and that's with a roomtemp of 24 degrees c. And I don't even run the two 19db fans at full speed, they run at 85% of full speed and they are noticeably more silent at that speed. I only loose about 2 degrees but I like the silence more than those few degrees.

I've modified the v-1 gpu cooler by bending up the top part, unfortunately the heatpipes didn't take the bending that well and got quite flattened... But luckily it didn't affect performance and now the gpu idle at 41 and load is 52 running rthdribl which is very gpu intense since it runs both HDR an AA at the same time. A since it runs pixels shader 2.0 it also proves that you don't need ps 3.0 to run AA and HDR at same time. Then again it all depends on the implementation of HDR, some forms can run AA and some can't. I must have erased the vmod when I bent the heatpipes so I can't overclock any more than before but that's easy to fix.

If you really feel like pressuring your gpu, try running in full screen and 16xAA ;) Running in a window and at 16xAA I get around 40 fps with my 7600GT. You can change the amount of AA by pressing the numbers 1 to 8.
