What's the maximum 'safe' temperature for inside a computer? The only sensor I have in my G4 for temperature is the SMART sensor on my 120Gb hard drive, read through Temperature Monitor. Yesterday was an especially hot day (for the UK) at 30 degrees C, the hard drive temperature went to 52 degrees before I turned off. I've taken the back panel off my cabinet, so that the air can get out instead of being stuck around the computer. Anything else I can do in this hot weather to help the temperatures?

My Maxtor usually runs somewhere between 30-32 °C, but it has been hot here too lately, and I saw it going up to 40°C (and this is the least active of the 2, the std Hitachi in the G5 doesn't give me a temp). However 52°C sounds really hot. Have you checked the manufacturer's website to see the safe operating temps of the HD ? Don't know about inside the computer, but I think it is more a matter of individual parts. Of course the heat inside the case heats up everything. Maybe you can put a fan on it so there's more air movement ?

I looked around a bit and for my Maxtor there a 60°C operating limit (datasheet). It is very hot here today as well (right now 32°C) and my HD Bay fan is going full throtle. The Maxtor is at 36°C and I don't know about the Hitachi std HD, but it must be pretty hot since the fan is spinning so fast.
So 52°C sounds hot, but depending on the brand, if it is a Maxtor it is withing operating limits.

It's a Maxtor 120Gb drive, as a second drive in my Quicksilver G4 (at the back mounted on top of the standard 60Gb). Thanks for the datasheet.

Here's what Apple says about your Quicksilver :

Environmental requirements
• Operating temperature:50°to 95°F (10°to 35°C)
• Storage temperature:–40°to 116°F (–40°to 47°C)
• Relative humidity:5% to 95% noncondensing
• Maximum altitude:10,000 feet


The PDF provided by Apple
I'm assuming a max of 35°C / 95°F is assigned to the inside of the case. With that temp the CPU would probably not be able to be cooled properly. It's the first time my G5 has seen temps like today (32°C) and while almost idle 15-18% CPU usage, they are at 68°C and 66°C.

My PC drives reached about 62-64C during an Australian summer before I worked on the cooling. Didn't explode, but obviously they were above the recommended temperature.
