Re: CPU TEMP and FAN SPEED
I wouldn't worry about the temps as long as they are under 70C. I think that the max temp for p4's is 80C, but I wouldn't recommend using it if the temps get that high. Now the temps will probably increase about 15-20C when you put the cpu under full load, so you should be fine.
I have a p4 too, and the same hsf too, but I just have the full copper version. I have oc'd about 400mhz and my idle temps are around 40C, under load temps a little over 60C. Fan is at 2400rpm which is the highest it goes to, but it's still doesn't produce that much noise.
