Error detected with the CPU fan.
Error detected with the CPU fan.
I've noticed similar discussions, but they didn't quite capture the exact concern I'm facing. I'm looking for clarity on the problem behind the "CPU Fan Error!" message. My PC is about a year old, and I encounter this issue when starting up. Initially, I tried turning off the CPU fan speed settings in the BIOS, which resolved the problem. However, I wasn't sure if that was the best approach or if further adjustments were needed. To help me better understand, I shared two screenshots from the manual of the mainboard (ASUS ROG Crosshair VIII Dark Hero Gaming). I connected my AIO via the correct cable in slot "AIO_PUMP" (number 4), and followed the instructions for "CHA-FAN1" on the bottom left of the CPU (also number 4) and "CPU_OPT" with "CPU_FAN" in the top right. I left everything as it was because I had no other cables, and I didn't want to change anything else. Now I'm puzzled about why this error still appears and how to fix it without using the Corsair software.
For another point: Can I customize the color of my RGB fans without relying on Corsair tools? I suspect a faulty RGB fan hub from Corsair might be the cause, which led to overheating. After disabling the software, temperatures stabilized. Once I removed it, things improved. I haven't installed any other software and prefer a simple static color.
Regarding temperatures: In one of my photos (Armoury crate), idle CPU temps are around 50°C and the CPU package about 60°C. Is that reasonable for the Corsair iCUE H150i ELITE CAPELLIX? I currently have five Corsair LL120 RGB fans in the case, planning a sixth soon after upgrading to an RTX 4080. I'm concerned temperatures might rise further with more cooling and better airflow. Since my current 1080 Ti can reach up to 100°C, I wonder if newer GPUs could handle it better. Would undervolting help? After updating BIOS to PBO and Curve Optimizer, I faced some problems. Blue screens appeared after optimization, but they stopped once I disabled both. I ran Memtest86 and Windows Memory Diagnostic with no issues, so RAM seems fine. My CPU may still have stability issues with OC/PBO/Curve Optimizer. Overall, this frustration comes from assembling a new PC and dealing with unexpected problems. My previous i7700K was much more forgiving.
It's an ASUS board, so connect the AIO pump to AIO_PUMP and the fans to The CPU_FAN. If your hub is used, all components should be linked; otherwise, one fan must be active to prevent the system from shutting down to protect the CPU and avoid CPU fan errors.
I modify the BIOS to match my setup and settings, ensuring I’m always aware of which fan headers are active and why. I’ve avoided problems, including situations where fans stop working unexpectedly, like when a CPU fan turns off entirely. The temperatures feel elevated, but your pump is running at acceptable speeds in the BIOS?
Hi, I haven't updated the CPU header after getting my first AIO. Now I'm running a custom loop with a water temperature sensor and turning the fans off. The CPU fan adjusts based on temperature, changing frequently—usually every 5 minutes when a task starts. Use the AIO socket for your pump and case fan 1 for the fans. If you have a temp sensor, you can connect it. My board came with one I could place anywhere, but it's threaded so it fits directly into my waterloop setup. Since the Armory Crate is unreliable, I've set the fans in BIOS.
Obtain a fan. Connect it to the CPU_FAN header. Problem resolved.
Corsair's AIO stands out in its design. Remove the RGB fan cables from the commander core.
