Hi All,

Recently, I bought an Alienware R12 (Air Cooling Version, Windows 11). In order to have a better cooling and noise performance. I did something like below:

1. I replaced its original stock CPU fan with a AIO liquid cooler (Corsair Hydro Series H60 AIO Liquid CPU Cooler - Santa powered).

2. I replaced its original front fan with a Noctua NF-P12 redux-1700 PWM and connect it to front fan header.

However, it will always throw an error message at pre-boot system performance check whenever I start/restart my computer. The error message is "Fan - The (CPU Fan) fail to respond correctly". The error code is 2000-0511 and the validation code is 111141. So, I tried to debug on my own like below.

1. Installed a VRM heatsink N1C1D (L-Shape) on the motherboard.

2. Upgraded the BIOS to latest version 1.1.8

3. Plug the H60 radiator 4pin to Fan Top header, H60 pump 3pin to Fan Pump header. Leave the Fan CPU header empty.

4. Plug the H60 radiator 4pin to Fan Top header, H60 pump 3pin to Fan CPU header. Leave the Fan PUMP header empty.

5. Plug the H60 radiator 4pin to Fan Top header, H60 pump 3pin to Fan Pump header.  Plug an extra Noctua NF-A9 PWM to the Fan CPU header.

 

All of above came with no luck. Any thought? 

Thanks in advance!
