62+ degree ok for PB?

kimo,
USB and Bluetooth are not the same. What I think you meant was that you wanted to get a bluetooth device (such as a mouse) with a bluetooth receiver that plugs into a USB port. If you have a powerbook with Bluetooth built in, you won't need this; if you are using a computer without BT built in, the USB dongles work pretty well.

Can you convert those temps to F? They do sound a little high. How do you measure the temp?

60c would be about 150f

My iBook runs at that temperature sometimes doing the things you are describing. I posted a threat about this earlier and got replies about how it was normal and everything would be okay if the fan is turning on. My CPU gets over 70 degrees C sometimes while just after playing WarCraft III and that is the only time I hear the fan. I think the fan kicks in when it hits 70 degrees or 68 or something. Anyways, I think you aren't having any problems and things are looking like they should be. I don't know why they run so hot, apparently G3's run cooler. So it is normal to have a hot G4. I wish they wouldn't get so hot too.

As for temp, 60C = 140F roughly. it is like 2.33 x C = F

Youre not serious are you?

The correct formula

is 1.8*C + 32 = F

but your result is correct.

I thought the C to F conversion was 1.8 * C + 32 = F?

Oops, the poster above beat me to it...

But I'll add this...

To answer the original question, 60 degrees is fine. Even 70 or 80 would be tolerable by the 7447 or 7457. In fact the maximum junction temperature for these chips is 105 degrees. The junction temperature is what the temperature sensor on the powerbooks measures. Take a look at motorola's specs for these processors.
