unlikely to be screws then if it is a phanteks block. EKWB just throws in a bag of assorted screws so its easy to mistake the wrong ones.
Any update? seen anything wrong with the card/loop?
I haven't got around to draining the system yet as i still need to use the computer for the next few days. So will likely be the weekend until i can do it.
On another note, i was wondering if the PSU could be an issue? i have the corsair rm850x so plenty of power but i was thinking for whatever reason maybe the PSU is causing some kind of power issue to the card and in return its causing something to overheat underload and cause high temps? Is that even possible?
