Gpu fans Won't spin.

[Phrxzty]

So I just recently purchased an rx6600 and a 750 watt power supply to go with it, I installed it to my motherboard(gigabyte b450m ds3h)and got the gpu to display but the fans stopped spinning after my pc booted up. I don't k ow how to fix this issue, also could it be my motherboard.

Most modern GPUs have 0 fan mode where fans don't spin until GPU reaches 50-60c

This is normal, expected behavior. By default modern gpu fans won't spin up until under load until they cross a temperature threshold set by the manufacturer, usually between 50 and 60c. If you wish for them to be on full time, download msi afterburner or fan control (link in my signature) and set a custom curve to turn them on.

Install HWInfo64 and run it, so you can monitor GPU Temps.

 

Then run something on the GPU and watch the temps, once it goes past 50-60, it should turn on the fans
