Predator PO3-620 i7 10700f and rtx 3070 Heating and fan

Linokino

Hello
I just bought the Pc desktop.
When I play video games, the CPU goes up to 90 degrees...even to 100.
I installed from the begin the glass side of the tower.
And when I look at it inside, the 2 main fans go fast and make some noise (until now ok it's hot).
But the CPU fan looks a bit lazy, almost stop rotating to be able to see the panel of the fan. I found it strange with a CPU almost at 100.

I saw some post already speaking about this problem, so my questions are :
-Is the glass side panel block the airflow? because the original one has some holes inside
-is it normal that the CPU fan looks to work half what it should ? 
-how can I push the CPU fan to go higher?

I hope not the only solution to this heating problem is to upgrade the CPU cooler... as of today is expensive enough this desktop.

Thanks for your help on this matter

The intake and exhaust fans spin fast because they are fighting a losing battle trying to keep the components cool. As for the CPU fan, well, it's not that good from the beginning.

As far as I remember, you can't adjust the CPU fan with the included PredatorSense software. This is a very interesting choice from Acer.

The CPU temp problem is caused by the inadequate heatsink and the thermal paste being used. If you keep reading this forum, you'll find that you can easily remedy this by spending 20 to 30 bucks on an aftermarket cooler and a tube of new paste. If you choose the right cooler, you don't even have to remove the original heatsink. Just unscrew four screws, clean and apply new paste and attach new HSF on the CPU.

As for GPU temps, you can use MSI Afterburner to control the fans. I would also recommend watching few Youtube videos how to undervolt and overclock your GPU at the same time. By doing this your GPU temperatures go down nicely with almost no loss in performance.
