For the price, the i32 is unbeatable. 25 quid on amazon.co.uk. I added a second Arctic F12 PWM fan (the same as the first one that comes with the i32) for an extra 5er... not that it really needed it. Used Arctic Silver 5 (as I have for years). My i7-6700 CPU idles around 30C and never even touches 60C even overclocked 5% on a Z170 board (yes, I'm a very safe overclocker). One year on it's still performing like a champ
