Faulty fan speed readings in motheboard ?Should I be worried or not?

Guyinslowmo · Jan 8, 2017

I own an 'Asrock b150 gaming k4 /hyper' & things aren't the way it should be.
So whenever i check the fan speed that are connected to mobo which are 3 pin fans; i get around 9800 and 57000 rpm readings! I can clearly see it shows 999 &1200 in miliseconds but most of time it shows like that insane speeds.(( Bios is latest stable 1.30,tried to update to beta 1.60 still nothing.))

So
Q.1 - Should I be worried or not? Is it gonna damage the mobo?
Q.2 - Why this happens?
Thanks in advance for any help.

Recommend to update the intel chipset driver first, because the sensors may not have the newer driver, and the chipset driver comes with that. https://downloadcenter.intel.com/download/20775

After done the update, may check the speed by other software like HWiNFO64 https://www.hwinfo.com/download.php or even in the BIOS hardware monitor section.

Ok...so I found a temproary solution.Actually it was 2 of my fans which were acting dramatically .they had 3 pin & molex connectors in it.But then I replaced with 3 pin only fan & now all is working fine.So I assume that's fan's problem.
BTW I earlier tried all your suggestion & even updated to latest beta bios but still was the same.Then I came to this solution.
