    I have heard that the G5 Quad LCS is unreliable, since they are about 9 years old. I was wondering if it would be possible to use a Corsair H100 or something for the LCS in the Quad. I don't own a quad so I am not sure how they put the cooling on. Just curious if I ever pick one up.:)

    If you're skilled enough, I'm sure it's possible. I imagine you'd have to fabricate a few parts that might require access to special tools.

    In principle I can't see why it mechanically wouldn't work with the correct adaptor to mount the CPU block. It's self contained and manages the pump/fan speeds itself.

    I run an H100 in my gaming PC - it's very quiet and efficient.

    So, hate to wake the dead, but has anyone got a different liquid cooling solution in their Quad yet? I have a single pump Delphi model in my Quad but the fans are loud all the time and both CPUs fail thermal calibration for overheat. Still boots and works though, but I have not put it to any real work to push it.

    I seem to be stating this regularly, but if your G5’s cooling system isn’t as effective as it once was, it’s time to renew the thermal paste, LCS or not.

    I have exactly the same problem, can't calibrate the fans because of CPU overheat. I need to replace the thermal paste, I hope I get around to do it next week.
