Hi Everyone,
I just completed a new PC build. Oddly enough, it was able to get to POST and boot. Linux Mint is installed on the drive, but there’s one problem…
The fans don’t work. Neither the ones that came with the case nor the ones that came with the CPU cooler.
Motherboard: MSI X670e Plus Gaming CPU Cooler: Noctua DH-15 CPU: Ryzen 5 7600X GPU: Radeon RX 7800 RAM: Corsair Vengeance DDR5 (Will look up specific model at home, can’t remember atm)
I have tried updating the BIOS, which did not change anything. Double checked all the connections, none seem to be connected incorrectly…?
Tried setting all the fans to PCM instead of DC… Still nothing.
What should I try now? I don’t want to damage the system by running without cooling.
How are your fans connected? Directly to motherboard? Fan controller? Daisy chained off one plug?
Directly to the motherboard
In that case, I’d be inclined to agree with Rimu about it being PSU related. I’d recommend carefully inspecting your 24 pin power cable and motherboard plug to see if any of the pins are damaged. Also, if you can, try and give each individual wire a little tug. Sometimes the pin isn’t locked in properly and when you plug the cable in, the individual pin will get pushed out.
It could be your PSU - https://www.reddit.com/r/MSI_Gaming/comments/17cyaj7/msi_x670e_tomahawk_fans_not_spinning/. If you have a multimeter you could check if the voltages on the PSU outputs are Ok.
I really hope that this isn’t the root cause, as it is also a new PSU… But I could just send it back and get a different one. I don’t have a multimeter. Do you have a recommendation for one that isn’t too cheap but not break the bank expensive?
Is there any fan control in the BIOS? Tried resetting BIOS settings to default?
Tried resetting the BIOS settings to default and the problem is persisting. The BIOS is not able to detect that any fans are connected despite them all being plugged in via their 3 or 4 pin header connectors
I think the board might just be defective.
