Hey, I just installed a new optical drive and 320gb 7200rpm drive from the stock hardware that came with the emac. Everything went smoothly and things have been running fine until I noticed that the temp was at 181.4F today. My G4 MDD usually can get up to around 125-135F but that seems way too hot. I was positive I put the thing back together perfectly but now I'm questioning whether or not the fan is even running? Is there software to test this? Also, the drive I installed was thicker 3.5" than the one that was in there already but there was an appropriate spot to mount it so I didn't think it was a big deal. Please help.
