I upgraded my PowerPC 7300 with a first-generation Powerlogix G4 350 daughter card. The G3/G4 Cache Proflier 1.3 control panel shows the operating temperature of the chip at 109 degrees Fahrenheit now that I've also dropped in two 128 Mb EDO Dimms and two more VRAM Dimms. There's a built-on fan on the daughtercard to cool the chip. Is this high/normal/ whatever? Anybody know if this means the fan is within parameters or needs replacement?

109 Celsius would be at the upper operating limit, but 109F should be okay.

There is a lot of temperature discussion going on in the processor upgrades forum you may want to peruse.

Is the fan running? Can you see it turning? How about the other cooling fans in the 7300? Are they turning? k

The fan for the power supply is turning, and the fan on the daughtercard is turning. Was wondering if adding a PCI slot fan would help by exhausting more air from the case?

109 Farenheit isn't too bad, that's only 35 to 40 degrees over ambient. But another fan can't hurt and may extend the life of your processor.

109 F (42.7 C) is cool for the G4. I wouldn't worry about it or do anything about it.

The 450Mhz Powerlogix G4 card that I am sending back because it does not work ran at 109-116 degrees Farenheit, and I beleive its too hot if it is over 139 degrees Farenheit. When I opened the case each time on my Powermac 8600/200 to try to get the upgrade to work properly and the card was extremely hot and made all of the other components in the case rather warm. I'll be sticking with an XLR8 G3 with this machine.
