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.
