Problems with starting from USB in the new build.
Problems with starting from USB in the new build.
Your order for the contact frame is confirmed for delivery on Tuesday. I'll let you know when it arrives!
I set up the contact frame, applied fresh thermal paste, and attempted to boot after double-checking all connections. Temperatures rose rapidly back to the usual 88°C, and the core voltage started dropping again as expected. I fixed the Q Code 98 issue and now see Q Code A9 (which seems fine based on this post). Everything is working properly in the BIOS—my three M.2 drives, RAM, GPU, fans spinning, etc. Interestingly, the AIO tubes didn’t overheat this time, and neither did the radiator, though I noticed the fans were still active. The daisy-chained fans are connected to the CPU fan on the motherboard and the pump runs through the AIO cooler. Am I dealing with a faulty AIO unit or is there a BIOS-related problem? I’m hoping for more details so I can file a replacement if needed, especially if it’s a defective cooler. Thanks!
Based on your pictures, your BIOS indicates the AIO pump isn't connected. This likely causes the CPU temperature to rise rapidly while the cooling components stay cool. Meanwhile, the BIOS shows a CPU fan is active. It seems the pump is installed correctly with good contact, but overheating persists due to high CPU load. First, verify all connections for the pump, fans, and RGB are properly plugged into the correct ports. Consult your manual if needed. Also, confirm the AIO pump header is enabled in BIOS. Try connecting the pump directly to the power supply rather than the motherboard header. You might need an adapter for Molex or SATA power if available. If possible, test the pump on another machine. Good luck!
I checked all available settings on the motherboard except CPU_FAN, but it still wouldn’t start. My cooler uses Corsair and my fans are Lian Li. The pump connector is plugged into AIO_PUMP but I haven’t connected the fan controller or any other header. In the BIOS, look for the AIO_PUMP header and make sure it’s enabled.
The BIOS varies from system to system, making it hard to pinpoint the exact location. Look for it under Fan Control, ideally in advanced settings. Be aware your BIOS might lack an option to turn off headers. Because the AIO isn’t functioning, you could test connecting fans directly to the chassis header and the CPU fan header instead. If the pump still fails, it may indicate a faulty AIO pump.
It was a faulty pump. I placed an order for a new one that I just put in, and it functioned immediately. The BIOS CPU temperatures reached their maximum at 35°C.
