PC reaches high temperature upon startup
PC reaches high temperature upon startup
Hello. I added a second SSD to my PC yesterday. Simple enough, but after installation the system overheated. The temperature spiked to 100°C right after turning on and stayed there. Fans and the pump ran at full speed (~2000 RPM, pump set to PWM). This forced the CPU clock down significantly—like 800MHz—even when not gaming. Even basic tasks like browsing caused noticeable lag. I changed the thermal paste and checked the power cables, but everything looked normal. The pump block felt warm, while the hoses stayed cool, which is unusual at those temps. I’m unsure if a cooling issue is the cause; without another test I can’t confirm. My BIOS is up to date (7C75vAD, 2023-09-01). My setup includes: RAM Vengeance RGB PRO (32GB, 3200MHz, CL16), AIO water cooler SilentiumPC Navis Evo ARGB 240, motherboard MSI MPG Z490 GAMING PLUS, CPU Intel Core i7-10700K, GPU ASUS GeForce RTX 3070 TUF, SSD PNY CS3030, and a 1TB NVMe M.2 drive. Windows 10 Pro 64bit. Anyone experienced a similar issue? Any tips to check if the problem is cooling-related without replacing parts? Thanks in advance.
You can sense water moving through the AIO tubes, and it appears to be warm. It looks like the pump could have been disconnected during the SSD installation.
I don't notice any movement in either tube and there are no pump vibrations despite the RPM changes. I verified all cables and connections—EDIT: near the pump I felt very light tube vibrations, though I'm unsure if it's water flow or another source. Temperature remains at 100°C while both tubes stay cold.
It's likely an air bubble became stuck in the pump or block while installing the new SSD. Adjust the PC so the pump is at the lowest point of the loop. You may need to gently tilt it back and forth or side to side to help move any bubbles through.
Thank you for your suggestion. I attempted it but unfortunately it didn't succeed. It's unclear, but I suspect the issue might be with the impeller. RPM is fluctuating, yet there appears to be no liquid flow. Updated January 21, 2024 by Gwynbleidd66. I tried the proposed solution and would like to share the outcomes.
