Increase CPU temperatures significantly when AIO temperatures remain low.
Increase CPU temperatures significantly when AIO temperatures remain low.
If your CAM readout indicates pump RPM yet coolant flow isn't occurring, an airlock might be blocking the flow. Remove the radiator from its case while keeping the CPU block attached. Turn on the system, then gently tilt and tap the radiator with your hands to check if the problem resolves. If not, proceed with a return for replacement.
AIOs aren't completely filled with coolant, leaving some air pockets. These trapped air bubbles can prevent the pump from moving coolant effectively because air is compressible.
Thank you for the advice—try tilting first, then tap later. I can't do this right now.
