System experiences high temperatures during startup.
Hello, welcome to the forum! You're doing great with your PC build so far. Everything seems to be working well—fans are running, display is functional, and you can access BIOS. You noticed the CPU temperature spiking to 78°C and seeing error messages in BIOS, which caused your cooling components to stop working. You're using an Asus Z590-E board with a Corsair H150i Elite Capellix AIO cooler on a 11600K processor. The radiator is installed correctly, but the BIOS keeps reporting CPU fan speed errors and flashing A9 code. This leads to your pump and radiator fans turning red. You're using a Core i9-13900K (or similar) and have mixed cooling setups.
For your situation, here are some suggestions:
- **Thermal Paste:** You're using the stock paste from the AIO. If it's not performing well, consider applying a high-quality thermal paste (like Arctic MX or Thermaltake) to ensure better heat transfer.
- **Cooling Configuration:** The AIO header is connected to the BIOS, but you mentioned changing it to the CPU fan header. Double-check that the AIO pump is properly connected and that the fan speed control is set correctly. Sometimes the BIOS needs a reset or a BIOS update.
- **BIOS Settings:** Try disabling any unnecessary fan speed limits in BIOS and see if that stabilizes temperatures. Also, ensure your CPU cooler is properly seated and not obstructed.
- **Cleanliness:** If the CPU appears dirty, gently clean it with isopropyl alcohol and a soft brush. Avoid using swabs unless you're certain they're safe for your chipset.
- **Temperature Monitoring:** Use a reliable temperature monitor to track real-time temps and identify if the issue is cooling-related or thermal throttling.
If you're unsure about any steps, feel free to ask for more specific advice. Good luck with your build!
The issue indicates your system believes the AIO isn't working. Checking the BIOS should show any fan speed readings. Even though I haven’t used an AIO, some repair guides mention you should feel a slight vibration in the pump housing when it operates. Is the device running?
I tested the pipes and noticed slight vibrations. I believe the AIO is functioning, but the BIOS didn’t detect any fan activity—just N/A. The temperature climbed rapidly to 80 degrees this time, and I stopped using it immediately.
I think your AIO isn't functioning properly, even though the temperatures were normal. It seems like the unit might be defective. Could you tell me what CPU model you're using?
I attempted to secure the tubes on my AIO, but I notice some vibrations and believe water is moving, though they’re just minor. The factory thermal paste was applied during installation, and the process was a bit rough but finished. My CPU is an Intel 11th Gen i5 11600K, and other temperatures look normal. However, the CPU is causing me stress and preventing me from booting to desktop or installing Windows. The temperature hit 80°C this time and reached it much faster than before.
I think the awkward setup could be related to that issue. I should get some isopropyl before disassembling to check if the thermal paste or cooler contact problems caused it. I’m unsure how to tell if my AIO is broken—it’s lit up and the fans are spinning. There are slight vibrations in the pump tubing. The radiator was installed correctly as everyone suggests.
The 15 11th gen model isn't overly power-hungry, using about 100 watts max. The issue might be minor—such as the AIO not making good contact or a faulty AIO. Check if your AIO cable connects to the AIO connector on your motherboard or a standard fan connector.
