Low fans revs - an issue or normal thing ?

post #1 of 6
Thread Starter 
I receive my CPU today and tried to put everything together to check if is working (still need to buy GPU, SSD & HDD to finish my build) and all fans was working but on very low revs. Is it normal in that build stage without gpu/ssd/hdd or changing anything in BIOS ? Or something went wrong ?

Could you list the exact components that you used, including fans?

How are they connected to the power, molex or MB header?

Short answer, no. It's not normal as those other components will have no effect.

What are the very low rpms? The fans are probably being controlled and will only spin up faster if there is a load on the CPU or the air in the case gets hot. Your CPU is only running the BIOS right now which is next to no load at all. It might even run in this stage without a heat sink (never tried that my self)

Plus fans are different...some fans have a max RPM of about 800rpms.

The molex fans should be running at their max speed. anything on the motherboard will be controlled most likely and as long as they are spinning at all they are probably fine.

I would still like you clarify how slow they are turning. Are they just kind of jerking and not spinning at all? Are they turning like a big wind mill speed?

RPM=Rotations Per Minute. How many times the fan spins one circle in a minute. You might be able to see this data for some fans in the BIOS.

Yeah, please find this out as what might seem unusual to you is completely fine.

You can find it in the monitoring page of the BIOS.

Are the ones that are plugged into the MB spinning at the same rate as the ones on molex power?
