well no doubt cooler master 212
btw its stable to 4.7 happy oc
Not on a 3570K... 4.5 will be a stretch with a 212 Evo on a 3570K. The cooler they use in this article http://www.tomshardware.com/reviews/ivy-bridge-overclocking-core-i7-3770k,3198.html
is close to the 212 Evo in terms of cooling performance and they saw thermal throttling at 4.5 on a 3770K.
4.5 on Ivy seems to require top end air cooling like a Thermalright Silver Arrow or Noctua NH-D14 or even custom water cooling.
Temp wise, 4.5 with Ivy is comparable to 5.0+ with Sandy.
