i5 7600k running at 95°

[TkF_Exile]

Hey guys, fairly new to overclocking.
I'm running an i5 7600k on a MSI Z270-A PRO Mobo with a Corsair h60 AIO watercooler

At stock speeds its running at about 30-35° idle and 65-70° under 100% load, using prime95. This seemed fairly normal to me based on what I have seen online. Although when overclocked to 4.3 GHz without changing voltage at all, It's running 45-55° Idle and under load it's running between 90-99° and throttling back to 4.1 GHz.

It doesn't seem normal to be running that hot. Is there any settings I should be changing when overclocking or do I just need a better cooler?

Thanks in advance for any answers.

You should only use version 26.6 or earlier of Prime95 for stress testing. Later versions use the AVX instruction set which cause abnormally high temperatures. If you're using the automatic overclocking settings, you're vcore is probably going too high (adaptive settings) causing higher than expected temps. Try manually overclocking and work your way up in frequency by changing the multiplier one number at a time and then testing. When it becomes unstable, add a little vcore and repeat the tests. Your max overclock will be determined by either the core temps (I would shoot for no more than 70C under load), or when you it takes more than 1.4 vcore too maintain stability.

The max recommended temp is 80c, or volts at 1.4. Exceeding these numbers for sustained periods of time (more than just an oops for a few seconds), can cause damage to the chip in the form of melting stuff. I wouldn't even think of letting it go past 80 to be honest. If you see it start to climb over that, immediately stop what it's doing.
