G4FanControl is an useful Application that can be used to specify a certain minimum temperature limit that much be reached before the fans on a iBook/PowerBook G4 laptop start up.

What's New
Version 2.2.2:
Fixed crash in "Check for updates"
Requirements
PPC, Powerbook G4, iBook G4
Be the first to recommend a similar software title.
i too paid for this app, thinking this was all there was out there that could save my Powerbook from eventually melting.
I then found Temperature Monitor elsewhere on MU.
TM (free) plus a $10 laptop gel cooler mat off ebay now shows my Powerbook running at these temps (with the first figure the present temperature of my mac, and the second figure Apples specified upper limit).
Battery 30/42, Power supp bottomside 40/82, CPU bottomside 38/75, Processor-controller 37/76, Trackpad 29/48. My mac has been running for 14 hours today.
Ok I know Temperature Monitor didn't help to keep things from frying, but I wouldn't now be without it as an app, it really does give you so much info about what's happening inside the box, and a ten dollar gel pad means I don't ever have to tinker with the inside of my mac.
An amazing app, I normally dont trust anything off the internet but I decided this was something that I had to try for the sake of my G4! So far after only a few minutes of running it my temperature has dropped very rapidly!
This is a great little app that works just as specified. You must be smart enough not to set the setting too high so as to damage your computer. One nice thing you can do is set the temps low so the fan goes on fast for a while and cools the computer down - then you can set them back to factory defaults and the fans won't come on again for a while.
One thing I would like to know is what are safe maximum temperatures so that my computer does not get damaged? I'd prefer my computer to be hot then noisy, but I wouldn't want to cause any damage of course. I read somewhere that a software update sometime a while back lowered the default temps because people were complaining about their macs getting too hot, so I assume the current defaults are for comfort and not equipment saftey
This utility worked perfectly from the initial install. By lowering the "thermostat" on the PowerBook G4 it allows the fans to run at a higher speed and kick in sooner. This successfully cools off the laptop.
I used to have to take breaks from writing because my G4 would get so hot it was unbearable on my lap. Now I've set the "thermostat" to 40 degrees Celsius and I can work comfortably for hours with the laptop on my lap.
Note: The temperatures are in Celsius. It would have been nice to be able to switch to Fahrenheit but that's a minor issue.
Expect the fan noise to be higher since the fans will run at a higher speed to move more air through the computer.
Finally be very careful about setting the temperature, make sure it's not higher than factory settings.
This program is good in that it allows you to let your PowerBook or iBook to run cooler, but it also allows you to do a potentially damaging thing: Setting the threshold so high that it disables the fans altogether.
This is a ridiculous oversight by the developer... It is extremely easy to accidently set the sensor threshold too high and damage your computer. There should at the bare minimum be a warning before doing this, or it would be best to disallow high thresholds completely.
So if you do use this app, you must make sure you don't set the threshold too high, and permanently damage your computer
My computer is making weird noises and I don't know if it's the fan or the hard drive that is damaged. I am considering buying this app so I can test disabling the fan for 5 minutes and seeing if that stops the sound (if so it's a fan problem, if not it's a HD problem). So having that feature, although potentially dangerous, can be useful I think.
It's funny that it has a GUI now, as I wrote up my own GUI front in in AppleScript yesterday. I would prefer that the GUI use the native Authentication dialog, so I think I'll be sticking to my own front-end for now.
The only way this could be better is if it were a MenuExtra. Keep up the great work!
This downloaded quickly, and when i went to open it, it just bounced in my dock, and then dissapeared. When I tried to open it from finder that didn't work either. Someone help!
I would love to use this app but when I tried to launch it nothing happens.
Running a 17 " PowerBook G4 1.5GHz and since I've used this poor computer so much the fan is a little whirry and it distracts me so I'd love to control it (without cooking it of course).
try and update your java to the latest version available through software update. after doing this, G4FanControl should launch.
....this application operates as advertised; it allowed me to increase the threshold level of one fan in particular which activated constantly, even when doing 'simple' activities such as skype conferencing. nice to have some quiet for a change.

Any thoughts?
