I posted a while back about my P4 1.6a that I overclocked to 2.13 GHz. It seems to work fine, and the monitor is telling me that it's steady around 48 degrees. The thing is, I've noticed some problems in GTA3 after playing for a while, and thought it could be heat related. Since the p4 chips are designed to slow down if they start running too hot, I thought that this could be my problem. Turns out that the status monitor was reading 56 degrees now... The question is then, what cooling upgrades are worth my while. Are some of the fans from companies like Thermaltake worth the money, or is the stock fan that Intel provides sufficient for this degree of overclocking. Besides CPU fans, what else can I do to help aviod overheating problems (if this is indeed that this is...).
