I leak tested for 24 hours as of yesterday before my graphics card came. Seated my CPU in etc. checked that the watercooling was still secure, and what do you know, I turn on my PC and water gushes all over my bloody motherboard. The PC didn't cut out so I yanked the power cable. What's the likelihood of it being intact? Unfortunately my graphics card won't be coming today as a result of it being out of stock here. Reckon if I leave it to try it'll be alright?
