I have a P4 2.66b and lately its fan been making some very funny noises, as though its catching on somthing. I took it of, looked at it a bit, put it back in and it still did it. I hit it which made it work ok for a little while, but now its playing up again. It speeds up and slows down a lot but thats due to the powersupply giving erratic voltage to my pc, getting new one soon. I want a new cpu heatsink/fan, the one i have just came with the p4, i would like something that would let me overclock in the future and is very reliable and good quality. I looked around a bit on www.overclock.co.uk and so far ive seen.
