From: Jack B. Pollack on 17 Jul 2008 16:14 I've got a G5 PPC tower running OS10.4. Using Temperature Monitor to monitor system temps it looks (and feels) like my system is running very hot. All the fans appear to be working when needed and the big ones come on when I remove the clear plexi-glass. The two internal SATA hard drives also appear to be really hot. Readings are as follows: Main Logic board air inlet 35.5c Main Logic board ambient 42.8c Main Logic board backside 45.1c Memory controller heatsink 59.2c Processor card ambient 42.8c Hard Drive 1 52.0c Hard Drive 2 48.0c Thanks

Do you have manufacturers' specs somewhere that say the components should be running at lower temperatures than you're seeing? -- My latest ballroom dance performance: http://www.youtube.com/watch?v=_W5Z5DGYIvM I kill Google Groups posts.

From: Jack B. Pollack on 17 Jul 2008 17:42 No I dont have any specs. The computer is like sitting next a heater! I also thought that I read somewhere that you want to keep you HDs below 50c (there so hot you really cant handle them).

However, the drives do appear to be running a little warmer than normal - mine were nearer to 35c (2x 320GB Barracuda drives). Don't be too concerned about the feel too much, they do get hot to touch, the sensor is only measuring the air around the drives, so will read lower than they actually are. ISTR that the sensor can drop down off the casing, and rest on the upper drive, might be worth checking that. It's also worth checking all the fans and vents for dust build up, you can remove the front CPU fans easily enough, and give them a good vacuuming. How you clean the rest is a matter of debate, personally I've used a plastic vacuum nozzle *carefully*, and never had any problems, otherwise a soft natural brush, but the best is to use compressed air to blow it out. -- Andy Hewitt <http://web.me.com/andrewhewitt1/> |
