Bios N/A fans ?

Hello, i recently noticed while i play games i can't hear my fans spinning and that got me a bit worried. i recently got this pc, never did any changes on it. when i go into bios for the first time i noticed some fans and AIO PUMP is on N/A  dont know if it was always like that the fans are still working but silently 

before all this my system was infected with a Cryptocurrency Malware i think i removed it completely with the help of some tutorials

but still the fan speed remains the same 

i am not seeing any overheating problems when i check on msi afterburner. but games sometimes crash 

would really appreciate any help
