I checked three motherboards and none of them let any fans function properly. Not the case fans, GPU fan, or CPU fan. It’s quite strange. I reached out to MSI about the issue—they said it was likely a motherboard defect, but I’ve tried three different boards and still had no success. I spoke to two support reps, and they all agreed it was a hardware problem. I also switched to an ASUS board without any improvement. It’s unclear if the power supply is the cause for all the fans not working. I can access the BIOS, see RAM, CPU, and SSD info, but nothing changes. The CPU and video card fans still don’t work, even with a different case. That’s unusual. Would it be worth testing a new power supply to see if that fixes things?
I believe the supporters might be the most likely suspects; have you attempted swapping them out?
All the fan connectors are positioned correctly. I tested one fan on another computer and it spun freely. MSI support helped a lot with troubleshooting. Only the back fan was connected, the GPU was removed, and I replaced RAM gradually. I reattached power cables from both the motherboard and the PSU. Fans are connected to their respective headers; the CPU fan is in its slot, not the pump. BIOS seems updated. Different motherboards were used. The case was unplugged, RGB fans were separated, and only the CPU fan didn’t spin. I suspect the power supply might be the issue.
I don’t have Windows set up yet. I can install it using the USB drive, but I’m holding off until the fans are running.
Your system runs well without fans as long as heatsinks are present. This setup is passive, so you shouldn’t damage your computer by simply launching Windows. Since you’ve tested three different MOS technologies and none have fan spin, it’s unclear what the main difference is between them. Assuming all components are swapped in, the problem persists—what’s the key similarity among these three options?
You examined three motherboards without setting up Windows at all.
