Back fan connected straight to the psu stopped working.

[Athrine]

Well you see my Back fan connected straight to the psu suddenly stopped working but, my cpu fan that's connected to the mobo and gpu fans are still spinning. I did install the backfan to the mobo to test it and it started working do you think somethings wrong with my psu? or it's just got loose or the molex is loose?

do you think I should try to re-plug it again to the psu molex?

If everything else is still working okay your PSU itself is not the problem. Maybe the molex plug is no longer a tight fit or one of it's wires have come loose. Doesn't your PSU have another spare molex you can try?

I actually re-plug it to the same psu molex and it started working again, though the back fan molex isn't tight you can actually see them shake a little bit when I shake the back fan molex.

I also think it's impossible for it to be the mobo and processor fault both are just brand new I just bought them this october 1.
