PSU fan runs at full speed
I have just built my first home server; after the first boot, the PSU fan runs at full speed. I couldn’t figure out what the issue was. Any suggestions would be appreciated.
Specs:
- 16GB DDR4 RAM
- Seagate IronWolf Pro 2x 4TB
- 1TB nvme Samsung 970 evo plus
- Gigabyte H610M S2H V2 Intel H610 LGA1200 DDR4 Micro-ATX Motherboard
- DeepCool GAMMAXX GT CPU Cooler A-RGB 120mm PWM Addressable RGB LED Fan Intel AMD
- 750W EVGA Power Supply Unit / PSU VAT INC
- Intel core i5-12400t QS 6c/12t Support ASUS ROG Strix B660-I Gaming WiFi LGA1700.
Are there any switches on the psu itself? Whats the exact model of power supply? "750W EVGA" tells us almost nothing.

Link to Reddit sadly, but more people seem to have "this issue". If you also have a GPU in there, you might just be taking too much from the PSU to idle.
Does it actually post and boot?
An exact PSU model would help tremendously, afaik only high end ones have variable fan speed, for example my cheap Thermaltake's fans spin at constant rate
