Artic Support advised assistance with connecting and setting up properly. They asked if you could share HV monitor temperatures from within Windows, compare them to UEFI readings, and provide a visual of your setup.
I believe I’ve found the fix – the pump is linked to sys_fan_2, which doesn’t adjust CPU temperatures by default. The main drawback is that the VRM fan gets very noisy. After checking, it turns out the pump is actually under CPU_Fan. This is my problem: when I power off and restart, the system overheats. Running CPU_Fan at maximum speed resolves it, and afterward I can let CPU_Fan operate normally again. What’s behind this?
You should set both the CPU fan and the system fan to maximum speed initially. Once temperatures drop significantly, they tend to decrease quickly.
Disclaimer: This is my 666th post... soooo if it's completely wrong, figures Your motherboard manual makes no mention of a SYS_FAN_2. Did you post the correct motherboard model in your OP? The picture looks like it's the same model, but just clarifying I don't think your pump is mounted to the CPU properly. That is the only logical explanation for the SYS_FAN having any bearing on CPU temp (it shouldn't affect temps, regardless of what you set it at). Found a video that seems to show mounting quite well. There's also version-specific videos made by Artic themselves here . Did you mount the radiator in the bottom of the case or something? If so, you've very likely got air bubbles at the copper water block and so cooling will be severely impacted. This is clearly stated in the installation instructions . It looks like you correctly used the offset mounts (indicated as #2 holes in the installation instructions) but also hard to tell from that photo. I can only verify the top ones are installed correctly. Can you post HW Monitor temps from within Windows? Do they match the UEFI temps? (I've now asked this twice) The motherboard manual clearly lays out the 3 fan headers as indicated below. The UEFI will control them exactly as they are labeled... if you have the pump plugged into CPU_FAN, than in the UEFI, CPU_FAN settings will control the entire Artic radiator, pump fans VRM etc. The photo you took, doesn't really help as it doesn't show the entire motherboard and everything connected, but regardless, clearly there's some confusion on what's connected where. So, I will take a guess: You have one standard PC fan (an exhaust fan I'm guessing) and your radiator/fan/pump combo. If that is the case, leave your pump setup as it is (connected to CPU_FAN), and connect the other fan (the exhaust fan) to SYS_FAN. If the fan connected to SYS_FAN has a 4-pin connector, set it to PWM and set whatever fan curve you want. It should likely always be running to move excess heat out the back of the case. To configure the pump follow the instructions straight from Arctic's website below: In your case, you will want to set it as PWM (not DC!)
