Hi guys, After taking in the advice I recieved from a few people in this group on cooling my G4 upgraded biege desktop, I went and bought a few things.
First off I decided to remove the scsi hard drive from the lower bay as it was generating alot of heat. I got a hard drive cooler fan for it and installed in the floppy drive bay. I don't use the floppy anymore so won't miss it. The hard drive fan just screws to the bottom of the hard drive and blows air on to the main part of the drive. Before I added this to the hard drive, after a few hours use it would be very warm too touch. Now its nice and cool. So that should help in removing alot of heat from the lower levels. Next came the processor. I picked up a CoolerMaster chipset fan... its really for applying to graphics card chipsets and came with a tiny heatsink. I removed that and added the fan to the top of the processor heatsink. I got this fan as it was the only one that was thin enough to fit and allow the top chasis to close down. I've looked on CoolerMasters website to find details on it but its not listed in their products page. Anyway since I've done these few bits, the tempature of the processor is around 48 degrees celcius, jumping to 64 when I have a few applications running. So the fan hasn't impacted that much. What I plan to do next is to drill some ventilation holes above the processor heatsink to allow the fan to draw more air through the top compartment... since its so close to the chasis I feel it can't pull in very much air. I may also add another fan of the same type to the side of the heatsink as I have a spare power plug and I might aswell use it. Having 2 fans, one blowing down and the other blowing across should help. I will also get some thermal goop for the heatsink and add that. I'm a bit reluctant to mess with changing the fan in the powersupply to a higher rate cfm model for the moment, but if I come across one I might give it a try. Any thoughts would be welcomed, thanks to all who provided me with tips and advice, Niall Niall Julian BA MSc E-Learning Support Officer Information & Computing Division School of Medicine University of Southampton ext: 24250 email: [EMAIL PROTECTED] -- G-List is sponsored by <http://lowendmac.com/> and...
