My pentium 4 530 Prescott version is running at around 50C idle, and 64-68C under load. I would like to get those temperatures down, as they seem quite high. I also wouldnt mind doing a slight overclock. Can anyone recommend a good heatsink for socket 775? Also I'm from canada, so I'm looking to buy from tigerdirect.ca. Im not sure that this really matters, but my motherboard is the asus P5NSLI, so please make sure it will fit. thanks you
