Hey guys. I overclocked my Core i7 4770k up to 4.1Ghz with stock cooler. For testing a rendering a high res 3D scene and got temps in image below. Question is if these temps are critical and would damage the CPU? Should I keep the setting or go back to default 3.5GHz till I get a decent CPU cooler? How do I know if the CPU is getting damaged or fried?

This testing was done on a 125w fx cpu. You have a 84w cpu. At stock clocks the 92mm will be ok, if loud, the 120mm will allow mild OC or extended stock clock usage, and the 140mm will allow for better OC or almost silent at stock clocks. The 120mm is another alternative to a hyper212 that sits lower, so is more appropriate for cases that won't fit the 160mm tall hyper212. The offshoot is the 140mm is 170mm tall so needs a larger case.

No. It'll self turbo to 4.0GHz anyway. At that clock the stock cooler gets hot and I'd recommend a custom cooler eg Coolermaster Hyper 212 evo - even if not overclocking.

Yours is running way too hot. It needs re-seating and/or cleaning out and the fan speed increased. Or get say a H100i if wanting to overclock seriously.

A stock cooler is not designed for keeping overclocked CPU temperatures down. The temps that you show in your screenshot are quite high for a CPU. A safe maximum should be around 70 degrees. I would stop overclocking until you have a cooler that can manage temperatures better, unless you want to kill your CPU.

The enermax ets t40 is roughly equal in performance to a hyper212. It'll pull temps 1-3° lower between stock idle and OC loads at the expense of fan volume. The hyper212 is often cheaper, performs roughly equal and is quieter. With will work for a mild OC at extended times
