CPU temps @ 80C while gaming

[ElfXD]

CPU temps fluctuate between 75 and 85 while gaming, I use mostly low/competitive settings that utilize CPU more also have it OC'd to 4.8ghz. Should I lower the OC?

What CPU

What voltage

What cooler

You give us the fact that its OC'd , but say nothing about what the CPU is, whats cooling it, what your overclock settings are, ect. For a question like that, that info is bare minimum background info.

 

High temp fluctuations at least for me, occurred in very high OC (along with high voltage) scenarios. The issue wasn't necessarily the clock rate, but the excess heat that clock rate brought with increased core voltages to support it. This is with a dual rad AIO liquid cooler. Lowering the core voltage closer to stock speeds helped reduce this fluctuation to be more stable, as at extreme OCs the fluctuation could occasionally hit TDP and throttle and ruin its performance or cause a straight up system lock up if it spiked too high suddenly. 

 

My guess Is you've played with your voltages maybe with a high OC, or the high clockrate alone is pretty high and raising temps. Just because its fluctuating as long as it doesnt creep up to or bounce off TDP is fine in my experience. I ran my 5820K at a pretty extreme OC constantly and with these high fluctuations and experienced about a 0.1ghz overclock degredation over a 1-1.5 year span (which was not a lot). I really pushed the limits on that thing all the time and constantly, and It held up like a champ. Really improved my confidence with overclocking.

yo my bad  I rushed that and typed quickly because I just remembered, I had things to do during the moment.
CPU - i7-8700k
Cooler - Coolermaster Hyper 212 Evo
as for the overclock, there was a feature my motherboard (gigabyte) BIOS with the "CPU upgrade" option the naming is stupid but its just basically overclock presets and have "i7 8700k 4.8GHz" option.
edit: i7-8700k's TDP is 95c, so as long as it remains in the 80s I should be good?

You should be fine with temps with a TDP of 95C. The motherboard might not be doing the most efficent overclock, its likely just pre-configured based on some presets and not very indicative of what you need. For example you might have a golden chip that overclocks excellent with lower voltage, but that preset doesn't account for that and will just pump whatever voltage they think necessary to keep 4.8ghz. Although great for normal use, the 212 evo isn't going to hold up to very high overclocks and high voltages, it just doesn't have the cooling capacity.

Its normal to have it at 80c at full load and OC'd.

Also TDP is measured in watt, not celcius.

A 95watt cpu should be paired with 95watt (or more) rated heatsink.

80*c is quite hot, but it should be safe and under the limit.

 

I mean, it should be okay to keep such temp, but it's better to have it running under 70 full load.
