Hey all. I have a P4 Socket 423 at 1.8ghz. Well currently I'm using the heatsink and fan that came in the retail box of my P4 and was wondering if there were any other fans of other companies that have a higher rating. Or is my Intel heatsink/fan good enough? I'm getting temperatures of around 40 C, which I realize isn't bad, but the fan seems a bit too loud for my tastes. I know that there are so many fans for the 478, but I rarely see any for 423. I went to Thermaltake's websote and they have one for the 423, but I think the specs are about the same as the retail one. Any help would be appreciated. Thanks in advance!
