i5 4690k performance at 4.4ghz with 1.2v stability
I increased my 4690k to 4,4ghz at 1.2v and it passed the stability check with intelburntest. Temperatures rose to 78°C (73-78°C across different cores). After changing the thermal paste to Arctic Silver 5 and using a Hyper 212 Evo cooler, I noticed these high temps only at 1.2v. Some users report higher voltages or more aggressive overclocks reaching similar temperatures, but I'm unsure if this is normal. Is it okay? I'm concerned about stability and safety.
78c at maximum is acceptable given the results from your IntelBurnTest torture session. Your actual operating temperatures should remain lower.
Additionally, the current standard testing procedure typically involves AIDA64 CPU with FPU support. Keep in mind that Haswell CPUs generate significant heat—your 4770k model generates around 150W.
If you're concerned about your temperatures (which are acceptable up to 85°C during tests), you might want to opt for larger coolers or switch to all-in-one water cooling units with more than 240 radiators. Winter conditions can also reduce temperatures by 10-20°C. Nothing beats a chill of around 17°C when the system is running idle.

If you're concerned about overheating (which is manageable up to 85°C during tests), you might want to opt for larger coolers or switch to all-in-one water cooling units featuring more than 240 radiators. Winter conditions can also reduce temperatures by 10-20°C. Nothing beats a comfortable 17°C at idle.
