Well my CM Hyper212+ developed a teeth clenching buzz/rattle after over 6 years 365 - 24/7 operation and the local shop had EVGA CLC120's on for $59 so i bit. Am i ever glad i did. My system (Ivy Bridge) is OC'd and crunches on BOINC projects 24/7 with heavily OC'd GPU's crunching on F@H just below it. Temps were in the mid 80's - low 90's on air, now they're mid 60's ~ 71C max. I'm impressed. Installation was simple and it's compatible with all modern sockets. My first foray into AIO since an old CM aquagate back in the S775 days . I can easily recommend this cooler.
