So I recently finishing my watercooling loop for the pc I built not too long ago. This is my first time water cooling and I can say it went pretty well...until I looked at the temps of my gpus (Two ROG Strix GTX 1080s). The top was hitting temps of 170 F on idle, while the bottom one was sitting at a cool 86 F on idle. I do not know how to fix this. I for sure know that I put the water blocks on correctly since I went step by step with the manual. I would love to start overclocking the gpus but this has been a problem I cant seem to fix. I don't understand why the water is bypassing the top gpu water block. Can anybody help?
