Have you got any updates for us on this? I've got the Gen 1 model cooler that seems to be slowly failing (but mercifully not leaking...yet) and just swapping it to some modern air cooling seems far more preferable for longevity of the machine
Could you elaborate on that? I've got a Gen 1 G5 Quad that seems to be slowly dying to overheating and would love to replace it with something more reliable. (I suspect mine either has pump failure or coolant blockage. Thankfully no leaks, yet!)
