I have had my mac mini for about 4-5 years now and its worked just fine, ive even upgraded the hard drive to 120Gb. I reformatted my computer for some spring cleaning and installed leopard (ive had leopard on here for about a year now) and now my computer seems to be overheating and going into sleep mode on its own. i dlled temperature monitor from versiontracker.com and it would go to sleep mode around 123 degree f, and ive seen it go to 131.8 F. i decided to top off the top and let it sit there uncovered and avg temp seems to be around 116.0 and it occasionally spikes up to 120 but drops. my fan seems to be working (atleast i hear it), and ideas on what to do because i cant keep my mini uncovered forever.

Specs:
1.5GHz PowerPC G4
512 MB RAM
Mac OSX Ver 10.5.6
HD 120Gb/ 70Gb Avail

I don't know if they ever really made the temp sensor in the G4 chip any good by the time they were making the 7447s.

Step one might be, since you took the cover off, to see if there is an accumulation of dust in the bits of the computer, or the vents? If so, perhaps one of those cans of compressed air(or whatever) for blowing out computers might be a good iDea.

When you do that, you can also upgrade the memory!

I tried Temperature Monitor, but it doesn't work with the G4 mini. It only returns the SMART sensor information for the hard drive. So, perhaps there is another issue with your mini?

Quote:
I am using the latest release of the application which should support my computer, but still no sensor at all, or only a S.M.A.R.T. hard drive temperature sensor is found. Is this normal?

Unfortunately there are some specific Macintosh systems which don't allow that sensor values can be read out by a normal application program. There are two different cases:

The computer uses a self-contained cooling control system. The hardware itself controls its own monitoring. No transfer of data from the sensor to the operating system is possible because there is no bus connection between the sensor and the actual computer.
The computer contains sensors accessible via a data bus, but cooling control is independent of Mac OS X. Apple does not provide any device drivers which would allow application programs to get data from the sensor. Only the firmware or a closed part of the operating system core has access to sensor data.
In both cases, it is not possible to develop an application program which could read out sensor values. The following Macintosh systems are affected by this problem:

PowerBook G4 Titanium (all models)
eMac (all models)
iMac G4 (all models)
Mac mini (all PowerPC-based models)

Hi

I had a similar but unrelated uncalled for sleeping.

I'd swapped out a HDD.

No hot air coming out in the enclosure.

The sleeping stopped with the enclosure off.

Turns out I'd accidentally rotated the fan unit 90 putting it back. Easy to do with its symmetry and 4 functioning screw holes.

Too easy to do. Embarassed

Regards

Paddy

Mine came out in 2005, and I'm still using it. Let me know how long "long" is, so I can plan it's replacement. Don't forget to factor in that it runs 24/7.

I figured it out the stock mac mini g4 is only 1.2 ghz his is 1.5 tells me someone has overclocked the processor i would do a complete system clean strip down the machine clean the heatsink replace the the heat sink glue and clean the fan also make sure the fan is working also for hard drive size max is 100 gig's to 150 gigs so your good there no problem's there i would do a full clean also check the capacitors on the main board to see if yours has been overclocked

this should help narrow down the issues[/u]

G4 minis came in 1.25, 1.42, 1.33, and 1.5 GHz.
