Hey,

I'm growing a concern over my i7 7700k reaching high temps (it used to reach up to 100*c, but now only goes as high as 80*c) when overclocked to 4.8GHz on 1.35 volts. (it can do 5GHz but it just gets way too hot for my comfort) I feel like this is way too high considering it's being cooled by a Corsair H110i V2 with IC Diamond thermal paste.

Anyone got any suggestions how to lower these temps?

Full PC Specs:

Mobo: Asus Strix Z270F
CPU: i7 7700k
Cooler: Corsair H110i V2
RAM: 16GB Corsair Vengeance LPX @ 3666MHz
SSD: Samsung 960 Evo 250GB
HDDs: 2TB WD Black, 2TB WD Blue
GPU: Asus Strix GTX 960 4GB (will be upgrading to a 1080Ti soon so don't judge lol)
PSU: Corsair CX500 (upgrading to RMx850)

Intel has already addressed the concerns of high temperatures on i7 7700k CPUs.

"We do not recommend running outside the processor specifications, such as by exceeding processor frequency or voltage specifications, or removing of the integrated heat spreader (sometimes called 'de-lidding'). These actions will void the processor warranty."

Intel's solution is, not to overclock your chip if you don't want to see high temperatures.

My suspicion here is, without taking a large amount of risk and de-lidding your CPU, you're never going to get the thermals you are hoping for.

Stress testing it now gives me 94*c, playing games like Arma 3 or PlayerUnknown's Battlegrounds gives me around 78-82*c, of which I achieved better on a i7 4770k with a stock heatsink. I'll try lowering the voltage a tad to 1.3 and continue lowering it until windows is no longer stable. I want to achieve a 5GHz overclock, I've managed to do it before and windows seems stable but it's just too hot so what do you think a good voltage would be for that?

Also, I've double checked:

AIO Pump is plugged into the AIO Pump header on my mobo
Fans are pulling air THROUGH the radiator from the front of my NZXT S340 (so i havent accidentally put it the wrong way and it's just cooling my CPU with warm air from the GPU)
There 100% contact between the heatsink and the CPU
