Hello, recently I build a new computer and everything is working fine except one thing:
When I shut down the computer from Windows, it doesn't power off. Windows shuts down just fine, monitor goes into stand-by, but the computer keeps running (fans are spinning, CPU has the usual idle temperature).
In this state, it is not possible to reset the computer using the reset button, the only thing I can do is to press and hold the power button to turn it off.
I tried many many things I read over the internet, but in the end I found out that this is due to my water cooling pump being connected to the W_PUMP fan header. If I disconnect the pump from W_PUMP header, the computer powers off correctly.
I have the newest BIOS 2202 and so far could not resolve this with any BIOS settings (I even loaded optimized defaults again and re-set everything from scratch). This was happening on a stock system, not overclocked.
My current computer configuration:
Asus Maximus VIII Ranger (BIOS 2202) • Core i7-6700K • 2×8GB G.Skill DDR4 3200MHz CL14 • 512GB Samsung 950 Pro NVMe • Palit GTX 1080 • Custom water loop
As a water pump, I use EKWB D5 [link]. It uses a molex connector for power and only uses W_PUMP fan header on the motherboard for PWM signal and reporting rpm.
Did anyone have a problem like this? Any input appreciated.
Thanks.
