Can anyone tell me if the Thermalright HR05 is enough to keep the north bridge cool when overclocking (Q6600) ? I'm looking for a good heatsink for it and this just seems like it will do the job. On a side note, reviewers on newegg all seem to agree that its no the best, but I still see people using it on the 680i boards. As for the southbridge, I was just planning on getting one if evga SB coolers if I decide to go this route.
