Hi @590_p0016ur_fan 

Welcome back to the Forum.

Most HP MBs don't provide a BIOS option to adjust fan curves. My guess is the fan speeds on the new new DeepCool AIO are causing this error. Or you did not correctly connect the: AIO pump or fan connectors to the MB.

Are all cooler fans spinning when you are using the PC?

Did you use the Deep Cool low fan speed adapters? I would remove these if you used them.

The 4:2 BIOS error and 90B fan error message usually indicates a fan speed detection problem or the CPU is overheating. Check the pump block installation/thermal paste application and reseat the pump and fan connections on the MB.

I've seen 90B fan error messages at system startup on other HP PCs. One can usually bypass the error message and the PC will run okay.

Your PC is shutting down which could also indicate a CPU thermal problem.

Hi @590_p0016ur_fan 

The DeepCool fans and radiator would be installed in the 45L Cryo Chamber. Are the DeepCool fans spinning?

If the front fans are HP case fans then check MB fan connections for the HP fans.

Download and run HWiNFO portable (free) at this Site.

Run HWiNFO to check CPU temps. You can also check other component temps and fan activity using HWiNFO.

I test PCs by running Cinebench (free) and HWiNFO to check temps.
