Thermalright is a brand that certainly needs no introduction. They are revered for their high quality coolers which are always on the leading edge. The Thermalright SK-6+ and the SK-7 coolers were introduced to me as budget coolers. But let me say from the get go that budget does not equal poor performance. Both of these coolers held their own in my AMD XP 2400+ system without a loud, high rpm fan.
