I have this in my Quadra 605, held on with some thermal tape. I soldered it to a molex cable I had lying around, and plugged that into the hard drive power (5V) since I use a SCSI2SD in mine which is powered off the SCSI ribbon cable. It just fits with my large 128MB RAM stick installed, the fan is pretty quiet running on 5V, and it’s total overkill but keeps the CPU nice and cool.
