CPU temperature high after installing a new GPU.

Pacman8030

A couple years ago, I bought a pre-built PC which is an ASUS ROG (Model #GL12CX-B7). It came with an Intel i7-9700F and RTX 2060 pre-installed. I recently upgraded my GPU to an RTX 3070ti. Ever since then, I noticed my CPU temperature rising to around 95 degrees Celsius when playing certain demanding games. (The GPU temp stays in the low to mid 80s). Is this normal? Does the CPU need a better cooler?

I forgot to mention that the PSU was also upgraded to 750 watts.

That's more than a little warm for a 65W TDP Processor with what looks like a 120MM AIO on it. I'd verify the AIO is running. Touch the water block while it's in operation and see if it's vibrating. Alternatively, track down the header and check the BIOS under QFAN control, make sure it shows positive RPM. If that header is a chassis fan, rather than an AIO, I'd set it to run at full speed. I don't like to throttle water pumps.

It actually came with an air cooler and the fans are running properly, but they're not enough to remove the excess heat generated from the new GPU and there isn't enough room in that case for more fans. I took it to the store and they ended up selling me another case to move my system into.

Ah, ASUS didn't seem to specify available cooling solutions. A new case with better airflow should help. Most likely you've got a GPU that's venting air into the chassis and it's considerably increasing the ambient temp inside the case.
