Yep, thank you to everyone for their input.
I did clean the GPU and tested it last night, but it just does not display anything. I then went on to notice that my one PCI Express slot was drenched in coolant, so I tried to clean this out using some isopropyl alcohol. I also then noticed that the motherboard was full of coolant around the CPU, I only noticed this now when I tried to refit the stock cooler to do the tests I will explain below. After a proper cleaning of both PCI Express slots as well as all around the CPU, I was able to:
- Run a GT210 in the secondary slot successfully
- Run a Radeon 7950 in the secondary slot successfully
- For both of the above working states, the PC still seems to reboot from time to time
- The RX 580 does not work in the secondary slot
- None of the cards work in the primary slot. The Hard drives do not even spin up when a GPU is inserted in this primary slot.
My next step would be to test the GPU in another PC but I have not had the time to do so yet.
So from this it seems like not just the GPU has been damaged, but my motherboard has seen damage too. Even cleaning out all slots using Isopropyl Alcohol has not really helped, and this is after a PROPER clean and drying out afterwards.
Then after this all happened, I tried to put the H100i back into the box, and take some photos of how and where it leaked. When I did so, I noticed that the one connection going into the CPU water block was so loose, that when I straightened the water hoses to fit it back into the box, it spewed coolant and then the connection came straight off. Seems this was even more damaged than I thought, could have just been years of warm water running through a plastic / rubber fitting that caused this?
I will submit a ticket to Corsair today to see what they can do. I surely hope they will realise that this has just cost me:
- My H100i
- My ASUS Gaming Motherboard
- My brand new RX580 (4-5 months old)
- My Corsair PSU looks water damaged from the coolant... Not a pretty sight in a windowed case...
Again, thank you to everyone for your help. I will keep you updated if I hear anything from Corsair!
