Hello All!

I do apologies if this has been covered, I have searched for quite a while! I just completed my build yesterday using all brand new components.

My issue is - the two 3-pin fans in my NZXT H510 are connected to CHA_FAN1/WP & CHA_FAN2/WP headers.

Both spin! However only 'Chassis Fan2 Speed' RPM is being registered in the BIOS/A-Tuning. 'Chassis Fan1 Speed' is displaying 0RPM same with 'Chassis Fan3 Speed' (which is not being used).

Thanks for your time, it is very much appreciated!

Cheers

Did some experimenting - It seems to be the case fan itself not the header. Looks like its a faulty NZXT case fan!
