GPU fan speed keeps on fluctuating

[Kvahuest]

So my pc is roughly 1 or 2 years old now, every single part was brand new.
When I'm playing certain games like Forza Horizon 4 and some other games my fan speed goes up and down, the fan speed shoots up when it hits 80c and then goes back down to a normal rpm after like 5 seconds, my GPU hovers around 78-79 on games with good graphics like FH4.
I have an RTX 2080, I have also got 3 intake fans, so enough air is getting to the card.

I just want to know if I can stop the rpm fluctuating since it is getting fairly annoying now.

sorry if the description is bad, i not good at stuff like this.

Msi afterburner is best option. You can set up custom fan curve over there

It’ll be best if you manage to isolate which fans causing the problem. Once you sure we can sort that out. For fans connected to the mobo you can most likely change fan settings in bios or get speedfan software
