Hey there, I've recently bought and installed a new heatsink for my FX-4170 (the stock cooler was WAY too loud) and since doing this, I've been experiencing serious lag spikes across all of my games, most noticeably in Battlefield 3. They occur roughly every minute and last for about 10 seconds each, dropping from 60+ fps to below 10. I have already researched this and many people suggested that I disable something in my BIOS called 'cool 'n' quiet', which I have done but with no improvement. I really don't know where to turn to next. Please help.

have you tried monitoring your temps while playing? it could be that you have installed the cpu cooler incorrectly, and you cpu is over heating. The overheating causes the cpu to throttle its clock speed, which can result in slow downs.

I have monitored my temps and they are normal - no higher than 55-60oC when under load. However when the lag spikes hit, the CPU usage goes through the roof. I'm pretty sure I attached it correctly.

No that was it. I just disabled cool n quiet in the BIOS.

Since you didn't change any settings, im assuming you also did not OC your CPU. In that case, I see no reason why a cooler would effect your fps in a game. Most likely it is another issue (i.e. software) that happened to occur at the same time. Try updating your GPU drivers to the latest version.

Nope haven't overclocked and I have updated my GPU drivers, my motherboard BIOS, and all other drivers to the latest version. I'll probably try taking the heatsink off and reapplying thermal paste just to make sure that it is properly installed.

yes, that would be a good idea. If this is the first time you are doing this, go to youtube for some tutorials
