TweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. More information on our testing procedure can be found in the T.E.C.C. article here.
I was asked not too long ago in the forums why I test Core i7 coolers on the standard test bed. My answer is simply this. I don't own a Core i7 system yet. I do feel however that our simulation still gives these coolers a good torture test to use as a comparison.
My take on the subject is this, if it does well on our test rig it will still do well on your i7 and vice versa. From what I have been reading the Core i7 processors run a bit hotter than the LGA775 processors clock for clock, you just need to expect a bit higher temperature readings than mine.
With all that out of the way, the Buffalo tests reveal that it comes in about average for our tested coolers performance. To me 59° idle temps and 64.2°C load temps are pushing it on 65nm LGA775 processor comfort levels, let alone if it actually was used on an overclocked Core i7 processor.
The sound levels I recorded are not all that bad, maximizing at 57 dB under 12V of power. They aren't pushing any envelopes in cooler quietness, but it is a fairly quiet solution.
