So I have an EK pump that started making a rather loud annoying noise. I had just finished bending the tubes to add my GPU to my loop, filled it back up, and this is what it was doing. The only think I can think of is I put primochill prep in again since the GPU never had the prep but the rest of the loop had prior when I was just cooling the CPU. So I am wondering two things, if the prep is what started causing the noise. Is this a bad noise, as in is something going to break? The noise is much quieter when idling, the clip is during a leak test so the pump is running at 100%.
