Cpu fan is not recognised
03-24-2019 04:20 AM

I have a hHP Envy 700-311na desktop pc with a core i7-4970 cpu and for some reason the bios does not recognise the cpu fan. I have tried three different fans which are all brand new. The fan does work as it sound like a low flying aircraft; but for some reason the bios has the fan running at 0 rpm even though it is working.
here are some screen captures:

Welcome to the HP Support Community @dave19711998
Make sure your UEFI is upto date???
FIXES:
-Add Microphone Record Test on specific products.
- Add Fan Speed Information on specific products.
- Add improvements to HDD and Battery Information page to include status icons.
- Add improvements to Battery Test to support specific battery supply vendors.
- Add supports and improvements when Battery Charge Management is active.
Not sure if it will help???

I installed the lates HP PC Hardware Diagnostics UEFI which is 7.0.0.0 according to the program which has to accessed when you boot up. I did update the bios. There is nothing in the bios or this program to test the cpu fan. It only allows me to test the cpu which is working fine.
