Hey guys, today as ive turned my PC back on, ive noticed there is a large bubble at the top of the tubing going into the reservour
I haven't noticed it before, nor have i found any leaks, but there is very little water flow through it, im afraid of it building up to much pressure and it leaking somewhere

I have noticed however that a part of my gpu block has cracks in it, where the other side is plugged. Ive held paper towel there and no leak was apparent, but im thinking that might be the cause of where this air has come from.

Ill post pictures from my phone in a sec

Thank you very much, any help is appreciated.

Heres the pics
Computer is off now.

NZXT Cam was still saying that the cpu fan was running (the header i have the pump on) and also the cpu and gpu temps were normal
