Default H100i V2 - doesn't appear to be working after move

Quick back story, I been using the H100i V2 for over a year with no issues. Recently moved, and while the machine was packaged securely I believe something internally must have broken on the cooler.

The machine turns on fine, but I get a CPU overheat error within 5 minutes without running much in the way of programs. The light on the H100i V2 also turns red.

I've taken the entire cooler off and checked all of the screws, the continue to work properly as well.

Any other suggestions before I grab a new one?

This pops up now and then with this model. Usually someone takes it down for cleaning, changes fans, etc., then 5 minutes later the temps are terrible and continually escalating. Most likely some internal debris that should not be there got stirred up and is now clogging the the pump strainer. You could try shaking it and hoping it relocates, but hope is the operative word. Either way that gunk isn't going to dissolve and will come around again. If you can watch your temps tick upwards 40-45-50-60-65... etc. while in the BIOS, I would say it's time to RMA or go shopping. Just make sure CPU_FAN or wherever the H100i v2 is connected has a full 12v/100%/disabled/Full Speed fan signal. The pump may not start if the voltage is low, like for a standard DC fan curve.

Something similar happened to me. I was using my H100i V2 for about a year without any issues and then all of a sudden I noticed the CPU temps were absurdly high and I panicked and immediately shut off my machine. After reading some posts in some forums, I thought the pump went bad so I bought a new one (went from H100v2 to H100i v2 pro and so I left most of the mounting hardware in place and swapped the unit out. To my horror replacing the unit did NOT resolve the issue so I circled back and found out that one of the motherboard posts was all willy nilly dangling on the board, looked like it was in place, but was not really fastened in place as well as I thought it was, I opted to remove the (4) posts from the older unit (instead of using the included back plate) and replace all of them with the modified ones from the newer unit. Then I put my unit down as usual and mounted them down with the mounting bolts and that did the trick. I immediately noticed heat was starting to dissipate again and my temps were back down to 26 * Celsius.

Kinda sucks that I had to buy a newer unit to get the newer motherboard bolts but I think they're a better design so I'm overall happier. Also I noticed in the pro version the tubes are thinner are made from a different material, & seem to bend easier without causing any kinks. I also like how in the pro version it draws SATA power

One way to differentiate your situation from the one described in post 1 is to look at the coolant temperature (or H100i v2 Temp on your old model). When you see continually escalating coolant temps that slowly build up over time, you usually have a cooler problem or some kind of restriction. On the other hand, when your CPU temps are wickedly high, but the coolant temp is back down just above room temperature, that means you probably have a contact issue between CPU and cold plate (or way too much Vcore). I am sorry it worked out that way for you, although I do think you are better off in the long run with the H100i PRO.
