I just moved my 2.7 from liquid cooled to air cooled (moved the air cooled heatsinks from my flakey 2.3 over).

So far it works great. I'm seeing around 168 F to 172 F in normal use for the CPU, fans go from barely noticeable to spinning a bit more where it is just backgroud noise. Using the native thermal module for the readings.

What temps are you seeing with your G5 and what are the fans like?

Note I haven't run the calibration software from apple, I just moved it over and went with it. Does it make a big difference?

Performance wise, it plays media pretty well so far with the 1950, surprised it play some denser 1080p videos just fine.
