Looking for a cheap heatsink for my e8400, currently have the arctic 7 pro but i find its to loud. After getting a new case ive found that the gfx card and cpu fans are pretty loud and since my bfg cant be changed without voiding warranty id thought id try and reduce the cpu side. Id be lookign for a heatsink around £20 or less, i wont be overclocking so it doesnt need to be one of them high performers. ANy recommendations?
