FOH, I have a confession to make. For over 4 years, my 4770k had a stock cooler, because I was too lazy to install the spare 212 Evo on a shelf 2 feet away from my computer.
After 4 years of procrastinating, I actually installed it, because I was rebuilding the rest of the case and replacing some failed fans and I had noticed the thermal paste finally starting to fail on the stock cooler (86c on p95_266 is bad mkay.)
Why do people even buy other air coolers? I've built a ton of systems for other people and these things are cheaper and better than almost all the air coolers on the market.
