Quiet coolers for dual and quad core AM2 & AM3 CPUs? in Hardware Hangout Posted September 18, 2013 I upgraded an AM2 system to a dual core AM3 Phenon II CPU, which came with what looked like a decent cooler in the retail pack. But when running anything that uses the CPU much the cooler fan revs up to high speed and is extremely loud. Even Firefox will make it spin the fan as much as Kerbal Space Program does. (When it's hard to tell the difference between the sound effects in KSP and the CPU fan noise...)I'm planning on moving this CPU to an AM3 board and unlocking it to quad core so it will need even more cooling. I have an AM2 dual core CPU that will work in this system but it runs hotter than the Phenom II. With the cooler that came with the AM3 CPU the AM2 chip has it running full speed as soon as Windows starts to boot.What's available that will keep the CPUs cool and quiet?
