Hi, I own a iMac G4 20" (usb 2.0). Lately I noticed the fan is spinning louder than before. It's now making sound at a level where it becomes annoying. (+ it never stops). I think age has started to wear it of, so I would like to replace it. However this fan is kina special. Since the design of the iMac G4 uses the whole case as a heatsink it pusheds air out on the sides. As someone demonstrated on the following image: Did anyone replace this fan? Kan anyone advice a replacement fan? I'm a bit reluctant to replace it because the iMac G4 is sensitve to heat issues. Any tips? When I'm going to replace the fan, I was thinking of putting a SSD drive in at the same time. For two reasons: slight speed bump + less heat production. But i'm not really up to date on the latest SATA/SSD technologies. I know the iMac G4 comes with IDE ports, however in Belgium it's very hard (and expensive) to get a IDE SDD drive. So I was thinking of getting a Sata SSD drive and a sata to IDE converter. Does this work? I can get something lik a Sandisk Standard SSD 128 GB SATA3 at the computer reseller nearby. What kind of convert should I get? Does the 3 in SATA3 matter? How about the dimensions, Can i fit a 2.5 drive in a 3.5 cage? What kind of hacks should I use there?
