I'm new to overclocking. If my core cpu temp gets up to 65 or 70C... 1. have i damaged my chip? 2. should i expect an actual SLOWDOWN in performance as temp goes up? i have an Athlon XP 2600+, trying to run it at 13.5x 166mhz bus, 1.85v. i have the stock fan, any suggestions would be appreciated. does a 10 degree drop in temp really help performance?
