Hi Kevin, Here's a link to Versiontracker url: http://www.versiontracker.com/php/search.php? mode=basic&action=search&str=temperature&plt%5B%5D=macosx&x=13&y=8 Looks like there are a couple of programs to do what you want. I used one (forget what) in OS9. Stopped using it because my 450DP temps were pretty stable and unexciting - fortunately. No idea how these will perform - YMMV Jon Original Message: ----------------- From: Kevin Willis res19rmg at verizon.net Date: Sat, 2 Oct 2004 23:14:38 -0400 To: G4 at listserver.themacintoshguy.com Subject: [G4] G4 overheating? I am wondering if my Gigabit G4 is overheating. I replaced the stock 400 Mhz CPU with a Sonnet 1 Ghz CPU last week. I had the system lock up on me last Saturday night after some extensive game playing. I haven't ran it very hard all week. Mostly checking e-mail and surfing the net. It worked fine all that time. I decided to work it a little harder this weekend to see how it handled it. I fired it up about 8:00 PM last night and have had it running ever since. It has mostly been running at idle... nothing very taxing until tonight. I started playing "Max Payne" for about 2 hours until the game crashed. I restarted the game and it crashed again. So, I quit that game and tried another game. Less than a minute into that game, the whole system locked up and I received one of those Kernel Panics. I received a similar message on my sons iMac a while back. After a little investigating, I finally put the little stand thing on the bottom down so the computer was up off the desk which improved the air flow. I have had no problems with that one since. I am wondering if I should add a CPU fan or not. If it needs a fan, can someone recommend a place to get one and a type to look for? Also, is there a program that monitors the CPU temp?
