Hey everyone, I'm wondering if I could get some tips on how to cool my G4. I just checked my temps today (I have 21 torrents downloading and my cpu never gets turned off,) and it is at 64º C while my main HD is at 58º C. That seems a bit high.... I already read the cooling tips on http://www.xlr8yourmac.com. The problem is, their mods either take up a HD slot or involve some cutting. I've seen PCI exhaust fans, and I have 2 free PCI slots, but I'm afraid they won't do much. I also don't want to get into anything too evasive such as Arctic Silver Thermal Paste, Liquid Cooling or replacing the heatsink (actually, someone replaced the heatsink and added the thermal paste. The temps only dropped ~ 5º C.) Does anyone have any ideas they might be able to lend me? Are those PCI exhaust fans really worth $5? is 64º C even worth fretting about? Thanks!
