Omen X 900-0xx cpu fan

 Hi all,

 

I had a failed liquid cooling CPU solution. I ordered a new part installed it and now the Cores are down to healthy range, 20-30 while they were in the 90's with the failed cooler. My problem is the fan for the CPU liquid cooling solution is just running at high. The fan starts out high on boot and onwards.

 

Is there something that has to be down in addition?

Thanks,

Frank

By the way I bought the fan from the HP parts store. P/N 855712-001   In stock   Heatsink - Thermal, 135W Liquid Cooling, ID16 TYPH..

 

Just thought that the BIOS is not recoginizing the fan properly and thus defaults to telling the fan to run at high.

Additional things I have done:

 

1) updated to latest BIOS

2 ) reset BIOS to  factory defaults

 

3) Hardware reset, Pull power for 30  secs then plug backin, then press and hold the Power button for 10+ secs.

 

I wonder whether I received a returned unit. I see that the fan's radiator fins are dented in a few places. Maybe wasn't right to start with.

It should have not changed but did you check the fan speed in the BIOS???

Yes , It is about 4800 rpm. There is apparently no way to alter it unless there is some magic keystroke. In workstations BIOS there are some combinations though I have forgotten them.

 

Thanks,

4800 rpm seems high.

 

What was the speed on the other fans???

Hi Reo,

 

Cpu FAN 4900-5000

PCI Fan 590

Hdd Fan 916

Top Fan none installed since I only have one graphic card, GeForce 1080

 GPU is running at about 49 C.

 

Do note that the fan is on high when I even use the boot level Diagnostic tool and when I am in the BIOS.

Sorry but there is something wrong with that CPU fan and I have no idea what.

 

If you take a " 0 " off the RPM's it would be just about spot on???

I am afraid there probably is. I noticed the fan's grill has dents in it.

 

I am a recent retiree from HP and I will just call in Monday to someone I know at this point . J
