GPU Temp rises under gaming severely

[stefanvorkinn]

In my Task Manager, the moment a game opens, my GPU rises to 95% usage, which makes my visuals lag slightly. The GPU temperature in GPU-Z rises to somewhere between 85 and 95 degrees. I just cleaned out my computer, moved it to a new case and added a new PSU (Corsair CX750M), as I thought maybe that was the issue. Turns out, I was mistaken. This happens with every game. I'm running on i7-6700K with an ASUS GTX 1080Ti Poseidon Edition.
Anyone have any suggestions?

Edit: Tried using different programs - some make the CPU overheat, while others, the GPU. Also, only started having this problem last week.

What's the wattage on your PSU and your clock on the GPU?

The Wattage on my PSU should be 750W. My clock should be this:
1733 MHz Boost Clock (OC Mode) featuring 11GB GDDR5X 352-bit memory and 3584 CUDA cores

Do you have any other programs running in the background when opening the games?

I've tried closing all programs; including background programs that I found unnecessary.
Mostly, it's only ever affected and spiked when a game has been active. Under certain circumstances with certain games, my CPU can also spike as a result.
