Hey guys, I recently finished building a new Pentium System for myself, which I built specifically for performance and QUIET operation. I've noticed however, that whenever the computer runs games, the CPU seems to get louder. When things are silent in the room, or when i'm using headphones, this slight vrooming can get annoying. Is there anything I can do? It's not a huge problem, but i'm a little disconcerted, since I built this computer for whisper quiet operation, and it really doesn't produce that right now.

sounds like you cpu cooler is temp controlled. When you play games your cpu is getting intensivly used so it is heating up so your fan speeds up to keep it within a range of temp that was preset or that you set.

Thanks Goldenknob, That makes a lot of sense, and now that I think about it is probably exactly what's occuring. Would you happen to know of any fanless cpu coolers for a Pentium 4 running @ 3.0c? This little baby looked interesting: http://www.tsheatronics.co.jp/zen/english/ncu1000_e.html But it's only rated up to 2.8ghz. Thanks again, Stretch

I think its your vid card fan that is ramping up once it starts 3d work. Check for fan control within whatever software came with the card. You may need to rig up something like the pic posted in this thread. http://forums.silentpcreview.com/viewtopic.php?t=9760&highlight=5600

Thanks for that suggestion. I may try and replace the vid card with something quieter. I heard that Hightech came out with a very quiet Radeon Pro 9800. It's supposed to used a variant of the artctic VGA silencer. Anyone have some info about that?
