you don't have much room to OC and you can get even a 80mm heatsink fan and still be better than the stock.
How bad is stock? So bad that i bolted an old core2 e6600 heatsink and got better temperatures
Thanks for the reply,
I'll look into the 80mm heat sink, thanks again.
If you have room, a 120mm based heatsink will be better, but for space most heatsinks with a 92mm fan based heatsinks will work as well.
