I built my first PC today and followed every instruction carefully. The system booted up smoothly, GPU worked, fans were active, and RAM displayed correctly. Initially, after just a minute, the CPU temperature jumped from 50 to 90 and an overheating warning appeared. I shut it down immediately. I connected the AIO cooler to the sys_fan4 port and reassigned it to pump_fan1. The temperature rose to around 70°C, which is normal for the BIOS. I tried connecting it to CPU_fan1, but readings didn’t change much. Both AIO fans were running, along with a small fan on the pump. I’m unsure how to verify if the pump is functioning properly. The AIO unit has only two cables—power and RGB control. In BIOS, it shows fan speeds but not pump speed. I removed the unit and checked the thermal paste coverage; it looked uneven, forming a blob in the middle rather than fully covering the CPU or AIO block. I plan to buy new thermal paste, though I’m not sure why it didn’t spread evenly despite following the steps. One tip I learned is that rotating the radiator from top to front (with cables at the top) can help airflow, and I heard air escaping when doing so. I’m not sure what else would be useful, but I’m worried the new paste might cause more issues. Anyone have experienced similar BIOS overheating problems? I’d appreciate any advice!

You might want to use the stock cooler that came with the CPU, though it's unlikely to be an AIO. There could be other issues like a faulty motherboard or the CPU itself causing overheating. Consider ordering an affordable aftermarket cooler just to be safe. Even if everything seems correctly installed, it's possible the AIO was forced in too tightly—check for loose screws or misalignment.

No, I didn't fully resolve the heating problem.

thanks for helping! I did find the solution for this overheating, it's silly. I found out that there are two different sets of screws for the backplate and one pack is just slighty higher not quite visibile for eyes. I must had confuse the packages. After re-mounting the aio using proper shorter screws, the block mounts correctly- leaving no space between cpu (I gues that's why my thermal paste looked like a blob in the middle and not full coverage of the cpu). Temps are now great. So the reason for behind itall is quite silly me, I'm glad for the help!

Thanks for the follow up. It's good to learn that it was a setup issue and we can all learn from it. I went for my build today and found out very quickly that my aio does not fit. I have the arctic freezer II 280mm and Corsair 4000D with a ASUS TUF ATX motherboard. The cooler fans hit the top of the motherboard heat sinks and there is no clearance for any size ram.

This situation would benefit from a more prominent disclaimer regarding RAM clearance, beyond brief notes on the Corsair website. Have you attempted mounting AIOs at the front of the case? I managed to achieve sufficient RAM clearance using low-profile sticks; Corsair LXP as I discovered this issue before purchasing the system.
