Dell computer came with an AMD Sempron CPU AM2 that stopped working. I bought an AMD Sempron AM3 mod. 145 and it is working flawlessly. The new processor came with a smaller sink and fan. Manufacturer says not to use any other sink. Does it make any difference or should I install older sink and fan?
Your going to be fine with the HSF that came with the 145. It isn't going to give off alot of heat anyway. Manufacturers always say that. I guess most people are technically voiding their warranty by using an after market cpu cooler. With your cpu, just use the stock one.
Prime95 for 30 mins and tell us the temps. I doubt you'll have to use another one, but this forum is for help.
