Question Just built new PC, CPU Fan is acting very strange.

Jun 29, 2020
So i just built a new PC. Everything seemed to be working great. Here is what I got:
CPU: AMD Ryzen 7 3700X 3.6 GHz 8-Core Processor
Cooler: Cooler Master Hyper 212 RGB Black Edition 57.3 CFM CPU Cooler
Motherboard: Asus ROG STRIX B450-F GAMING ATX AM4 Motherboard
Memory: Corsair Vengeance LPX 16 GB (2 x 8 GB) DDR4-3200 CL16 Memory
Storage: Kingston A400 240 GB 2.5" Solid State Drive // Inland Professional 1TB SSD 3D NAND SATA III 6Gb/s 2.5" Internal Solid State Drive
Video Card: MSI GeForce RTX 2080 SUPER 8 GB GAMING X TRIO Video Card
Case: NZXT H510 ATX Mid Tower Case
Power Supply: Corsair RM (2019) 750 W 80+ Gold Certified Fully Modular ATX Power Supply
Operating System: Microsoft Windows 10 Home OEM 64-bit
Wifi Card: ASUS PCE-AC51 AC750 Wireless Dual-Band PCI-E Adapter

I just want to state early on that throughout the whole time my new PC has been running, the CPU temperature is ranging from 35-45, and the rpm of the CPU fan has been around 900-1600 the whole time.

I downloaded some games to test them out and after a while I noticed a very loud purring sound + vibration that sounded like BrrRRrrRr. i did not even have a game running when I noticed and I tried to look up what was going on. I ended up going into the BIOS and changing the speed based on temperature curve stuff. When i turned it back on, it sounded great! very quiet and normal, but about 10s into me opening the game back up it instantly started again out of nowhere. I made sure all my drivers were up to date and shut it down and back on again, and this time tested every other game. It seemed to work fine in the other games but when I opened that same game as before, it took a minute, but then shot right back to doing the same thing.

The game that seems to be making it do this is not some super fancy hard to play game either (Risk of Rain 2), but for some reason this only seems to be happening for this specific game. I checked to make sure nothing was in the way of the fan for it to be hitting as well, and tried it again with lowered graphics on the game, but nothing is working. As mentioned before, it was not a case of the game causing it to spin way faster or overheat, as those number did not really change.

Also even when the game was only open for like 30s, the noise would not stop after it started until the PC was turned off. The longest i waited with 0-2% load was 20 minutes with the noise never stopping.
