yeah, I had to have my 60mm vertically mounted in the front of my STH10 so I could use the valves to bleed the air, otherwise it was a crap shoot.
also - removing it + the leaky ancient EK radiator increased my temps by basically nil. Not a huge shocker really, the original loop was built to cool 3x GK110 titans, 3930k, 64gb or memory, & mobo.
The EK radiator sprung an unknown leak somewhere inside the radiator after 4-5 years.
The Alphacool radiator formed a leak at one of the plugs after 2 years.
I'm excited for the day that the rest of my radiators fail so I can finally upgrade to some epic black ice tier units, then I can use half of my 40+ AP15s in a different build
