I'm experiencing issues with my CPU getting too hot. It was built nine years ago, and the AIO was installed about one and a half years ago. Initially, the specs were: GPU GTX 1080 Ti, CPU Intel 8700K, 16GB RAM, TridentZ RGB 3800MHz, water cooling EK-AIO Elite 360 D-RGB with six fans, and a mobile case from ASUS ROG Strix Z370-E. I believe the AIO is the cause since the CPU heats up significantly during use. At idle it stays around 70-80°C, but when tasks load it rises to 90-100°C as confirmed by the monitor. I noticed the AIO tube getting warm at startup and cooling down quickly. The pump header on the case is connected to the AIO_PUMP via PWM, set at full speed regardless of temperature. Normally I could overclock the CPU to 5-5.1GHz, but it returns to normal when the issue started. This has occurred three times now; after a few days it stabilizes with idle temps between 40-50°C and peaks at 80°C during gaming or streaming. If I disconnect and reconnect the AIO_PUMP, I hear a brief humming before it stops, suggesting the pump may be faulty. There might be a way to verify this. Alternatively, I could try troubleshooting steps or seek professional help. The warranty is still active, but sending it to the reseller for confirmation would cost me. Since the problem seems intermittent, I'm worried about losing money and not being able to use my PC during this time. Any advice would be greatly appreciated!
Does the pump output any RPM when this is happening? I am also suspecting that the pump is failing leading to the higher temps as there is no liquid circulation. You should ask EK first as they might send you a shipping label to send it back to them for checking, this should take a lesser time than RMA'ing via a middleman (Dealer).
The bios indicates a speed of over 3400 rpm and temperatures remain elevated.
