I disabled the pump on purpose to simulate a failed pump. Then I tested this against using no Sense Skew (aka allowing CPU thermal shutdown to happen) vs. Asus' Sense Skew defaults (aka forcing the CPU into a code 8 crash instead of thermal shutdown).
Not sure if its a coincidence with miskew or his aio just gave up ghost especially at high temps (theyre made pretty cheaply to begin with). And miskew isn't an Asus thing, its an AMD thing lol.
It's Asus decision to enable Sense Skew and their decision to use a default value that disallows thermal shutdown.
You can buy a pressure relief valve and add it either in line or on a radiator port. I've had no issues with extra pressure to begin with, and if i did it would just raise the level in my reservoir (which i dont keep fully filled for this reason), AIOs are filled and filled fully, they have no where to expand if something goes wrong so stuff just pops off.
Yep, the reservoir with extra air and pressure relief is an advantage of custom systems. I don't know whether this would be able to withstand temperature close to 100°C, because I don't know what the boiling point of coolants is and how high pressure is inside the loop (which lowers the boiling point).
Its a shame your AIO went, if i were you id clean some of your parts with distilled water, wipe em dry then let it air dry. You could even use compressed air at very low psi if you have access to a compressor.
A simple hair dryer should also do the trick there.
Concerning the AIO, one reason for me to start this whole test scenario was that I wanted to know what happened when all this heat builds up on a system that does not allow thermal shutdown. Now I know the weak points and can work with that knowledge. I don't want our home to go up in flames just because I left the PC running unattended. Furthermore some people rely on my consulting for various computer related stuff, so I like to find out these things by practical experiments myself instead of just relying on spec material and forum "hearsay". Not that anyone will ask me about liquid cooling anytime soon, but the opportunity came up anyway.
