[SOLVED] Cryorig H7 fan extremely low RPM compared to cpu temps.

I've looked at a bunch of forums and I haven't found the answer yet. I have also tried controlling it with SpeedFan but it doesn't detect any of my fans.
My motherboard is an Asus Prime Z370-A (incase anyone knows or thinks it's the motherboard, I have messed with the motherboard settings before but didn't notice when this problem started happening).
I honestly don't think it's the temp detector on the fan or where ever it is (i'm stupid ik) because the fan's RPM SLOWLY, VERY slowly, goes up but only to about 800 RPM (max rpm is 1600 RPM). Also by slowly I mean it takes about 10 minutes of cpu temp at 70C or higher for the fan to go up to at least 800 RPM.
Soooo yeah, if anyone knows why this is happening, it would be G R E A T to know :)

That's controlled by the mobo, and not the cooler, the cooler is essentially dumb, it's a block of aluminium with a fan bolted on it.

Somewhere in your bios you'll have fan settings, something like silent/performance, switch to performance. 70C is not at all bad, so the bios when set on silent is not going to ramp the fan up particularly.

This is assuming your CPU fan is plugged into the right fan header on the mobo
