Power supply 0 rpm warning

[Nironakamedus]

My power supply is given me a 0 rpm warning on bootup. it does seem to be running and cool air is coming out. I just moved all my components in to a new case, however everything else works fine.

Some older PSUs had a speed sensing wire to connect to your MB, though they're rare now. There should be an option in your BIOS to disable the warning.

What make is your PSU? If it is a high end Gold or Platinum efficiency Power Supply Unit, the PSU will switch off the cooling fan if the Power Supply Unit is not under a certain percentage of power load, because Gold and Platinum rated PSUs emit little heat from the components, thus meaning the fan is not needed if the load is under a certain percentage. Just make sure your PSU is of a good brand and not a cheap pile of garbage bought from a local PC store.

It could be the fan failing. Are you sure you didn't damage your PSU while installing it in a new case?

If so, I would advise on replacing it. The Cooler Master GX series PSUs are not great. They're known to fail under load because they can't reach their claimed wattage. If you're thinking of a replacement, I suggest this PSU -

XFX Pro series 750W 80+ Bronze certified PSU - http://pcpartpicker.com/part/xfx-power-supply-p1750snlb9

This is a much, much higher quality PSU. Ideal for your potential replacement.

Im not sure if i damaged it i handled it carefully, i didnt drop it, However the fan is running i can see but not as fast as usual.

If it's running, it should be OK. I'd replace it though, because it's not a good PSU to start with.

What's the rest of your build?

Pick up a good 500W+ from the brands in my sig.

However, there shouldn't be any way for your board to pick up that the PSU's fan is/isn't spinning without the PSU fan cable, which most PSUs don't have anymore. Are you sure you didn't change anything in the BIOS?

 

[Nironakamedus]

Yeah, havent touched bios. btw is corsair a good brand?

Yes.

Thanks for your help guys, one last thing should i just dont care about the warning until i get a replacement?

 

[Someone Somewhere]

Yeah.

Still lost, because the only way you can be seeing those is if you enabled it in the BIOS, or unplugged the cable when you shifted cases.
