Software for Cooling a PB ?

Okay, this is probably a silly question.
In my pre-switcher days I came across a few laptop utilities which would do (or claim to do) smart things with processor, disks, fan control etc to help keep various laptops running nice and cool.
My Rev.A 12" PB (with bluetooth, airport extreme and total of 1.12GB RAM. Original battery, still working really well) tends to run a little on the hot side (50C) even when sitting on a Targus ChillPad (twin USB Powered fans)
Are there any equivalent utilities for a PowerBook that may help ? While I don't want the fans running all the time I like the idea of my machine not dying because it's been running at 51C+ for an hour (it just hangs until it cools down a bit, then recovers as if nothing had happened)
Any suggestions ?
Are the new 12" or 15" PBs better in this respect ?

As far as the CPU goes, 51C is not hot. Though the case may be a little warm to touch.
The only thing I am aware of is the built in control panel/preference "Energy Saver". It allows you to change the Processor Performance from Automatic to Highest. Setting it on Auto allow the processor to cycle.
Hope this helps...

Agreed on the Automatic settings for Energy Saver, especially if you want to increase battery life.

As stated, 51 C is nothing. The machine is designed for this type of heat. And if the machine ever gets too hot (rare unless you're computing with a blanket wrapped around it), the machine simply goes to sleep on its own. Your machine is not going to die because of overheating.

if it's not stopping because of the heat... then what's causing it to freeze ?
leaving it alone on the coolpad (or the iCurve) for a while and it happily comes back to life after a while, and the "Temperate Monitor" app reports CPU is down below 50.....
It's got me stumped !

my bad...I missed the part about the computer hanging up when it gets to 51C.
I don't know what the problem is, but if you have any warrenty left, you should take it in. Mine will run all day (and night) at 60C+.
Sounds like there is some part that doesn't like the temp.
The amount of memory you have looks strange to me (1.12GB). I assume it is really 1.25GB? In either case, did you add the additional memory, or did you buy it from Apple that way? If you bought and installed the memory yourself, the memory could be suspect. Try running it without the 1GB stick and see how it performs vs. temperature. On second thought, try running it without the 1 GB stick no matter who installed it.

Rev A only had 128 MB of memory onboard.

memory doesn't make a difference (would have been easy).
Supplied and fitted by my original dealer. It's not Apple branded but it's caused no issues.
the freeze isn't consistent. Some days it runs happily at 55+ but on the days it's sulking 51 seems to be the bad point. Swapping the RAM out on those days (either back to bare 128MB or just swapping the 1GB stick with the old, Apple, 512MB stick) doesn't help... if it's having a bad day ... it has it all day !
It's been in for a look twice now (once under warranty and the power management unit was replaced - apparently a common Rev.A problem ? and once not under warranty but the dealer looked at it FoC - it helps I'd just ordered two PowerMacs for a client I guess !)
I guess I'll live with it until the new G4 (or dare I hope G5) PowerBooks are announced and I save my pennies for a new machine !
