I could use some help deciding which coolers to buy. First would be in my wife's PC. I got to the point where I can't stand the constantly changing buzz of stock Intel cooler. The board has LGA 1156 socket, and there is the first gen Core i3 CPU, only barely overclocked (I don't think I will dig too deep into this, but the question is still opened...). I need to replace the damn thing with something quiet and well performing. Ideally as passive as possible. The other is my own PC. This is more like a question to near future as I still have my old P45 board, but I intend to upgrade to Ivy Bridge as soon as it hits the market. Now I am a fan of Thermalright, but after reading some posts recently, I am in doubt. People say the coolers don't have flat enough surface, and I don't want to do any additional work in that area at all. I have HR-01 in my PC - I think - but since it's been quite some time since I last screwed around, I don't remember how it looks upside down. Is there anything similarly massive and performing I could buy, or is it ok to stick with the brand? Of course, same deal as with the first PC, I want it as quiet as possible. No idea if I should expect IB to be able to work with passive cooling only even if the technogy is much newer and producing much less heat.
