I recently upgraded my 1.25ghz G4 iMac with a Pioneer DVR 116DBK and OSX 1.5.6. I've never had an iLamp open before so I was careful to clean the thermal pads and apply fresh paste. Since it has run for almost 5 years continuously it was choked with dust and cat fur, which I cleaned out thoroughly. The copper tape strips I pulled off the old drive didn't stick to the new drive very effectively, and one of the screws crossthreaded and wouldn't go back in very easily. But after I plugged it back in and rebooted the second time everything worked OK, and the OS upgrade installed with no problem.
A couple of days later I noticed the top of the dome was extremely hot to the touch, and a little while later the computer shut itself down. I unplugged it and left it overnight. In the morning it was working just fine, and I noticed the fan running a couple of times. The fan keeps it only barely warm, when it's running. A day or two later it started overheating again. and I shut it down overnight (but didn't unplug it). Now it overheats withing a few hours of use, and the fan never seems to run. I poked at the fan blades thru the vents and they move freely but the fan doesn't seem to want to start. So, can anybody tell me if this sounds like a bad fan, a bad sensor, something unplugged, need a new PRAM battery, or what? I would think the thermal pads are probabaly making good contact or else how does the metal on top of the dome get so hot? Thanks! Owen P.S. My wife replaced her Flower Power with an MBA instead of a newer iMac. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to Low End Mac's iMac List, a group for those using G3, G4, G5, and Intel Core iMacs as well as Apple eMacs.
