Updated: Issue resolved! The 24-pin cable connecting the pump to the commander core wasn’t properly seated. Thanks to everyone who responded. This is my initial PC build, so please forgive any obvious oversights. For reference, here’s my parts list: https://pcpartpicker.com/list/znzDkJ Key components likely include an Intel i7-13700K, MSI PRO Z790-P Wi-Fi ATX LGA1700 motherboard, GameMax GX Pro Rampage 1050 power supply, and Corsair iCUE H150i ELITE CAPELLIX XT 65.57 CFM liquid cooler. The PC should start up normally, all fans are active, but CPU temperatures spike rapidly—around five minutes it triggers a shutdown warning. I haven’t installed Windows yet and haven’t used the iCUE diagnostics tool. BIOS reports fan speed at zero despite the pump tach plugged into CPU_Fan1 on the motherboard. I’ve re-seated the cooler several times; the thermal paste appears evenly applied. Troubleshooting is tough because progress is slow and the power draw in my office circuit breaker activates roughly two-thirds of the time. This suggests a wiring issue or excessive power consumption, possibly affecting both the pump and CPU. Any advice on next steps would be greatly appreciated. Thanks ahead!

You may wish to minimize the issue because I don’t think other devices would handle sudden power drops well. You could also reach out to an electrician to improve your office power circuit. Regarding overheating, if your motherboard has a pump header, connect the pump there, as suggested by @Hinjima.
Identical results occur regardless of the device used, as the motor displays zero RPM.
