This is a custom built computer, and I'll post specs later if they are necessary but I'm just concerned about one of my fans. Usually I dont mind fan noise but this is kind of absurd.

This is from speed fan.

Is something going wrong? Should I open it up and try to fix it? Which I'd rather not do since this comp is a catstrophe waiting to happen until I get the money for a bunch of new stuff for it.

Thanks for reading.

What is fan 2? A system fan, or CPU fan?

How is this connected, via the motherboard or directly to the PSU?

Is this a three or four wire fan, or a two wire fan?

Both fan speeds have me a little concerned.
My CPU fan spins and ~4,000 rpm

One of your fans spins at 17 rpm?
Thats barely moving at all!

I would pop the case and see if there appears to be anything unusual with the fans, like oscilation.
Shut the system down afterwards and look to see if any of them need to be cleaned.
In the beginning there was the command line.

Ditto here, my two fans run around:


The 1834 doesn't bother me so much as the 17 RPM, which is barely turning.

never had a fan of any sort spin less then say 800 RPM, usually theyre over 1000. the one exception, is before I went crossfire, I had one side panel fan that would only activate once the system hit a certain temperature-but it didnt spin at 17 rpm. It either wasnt spinning at all (zero rpm) or was hitting 800+ rpm.

I'd be tempted to poke my head inside the PC while its running and see which fan is the one that is turning at the same rate as the earth moves around the sun... Rule of thumb, if you can see and count the blades then its either turned off or time to replace it.
