Monitoring CPU Temperature?

Tuesday's postings on Versiontracker had a freeware CPU temperature monitor.

Visit www.increw.org. You will need both the speedit.kext and the CoreDuoTemp app.

Has the CoreDuo Temp program, which is what I use. The temperature of your CPU is displayed in the dock icon while the program is running.

What's not clear is if you have to install Speedit before the CoreDuo temp app, or not.

I could not get it to display frequencies last evening and it was giving me some errors also. But I had already been running the Speedit kext...

Well I cant help you with the first point.
But 63 celcius sounds normal to me at 100%. I'm no expert, but I tend to get in the 53 to 65 range under normal to fairly heavy workloads. I wouldn't worry about temperatures at this range. I would say 75 celcuis and above is getting too hot.
Hope this helps a little.

speedit.kext is a Kernel EXTension, therefore has to be loaded using Terminal.
put speedit.kext in your home folder, fire up Terminal and type in:
sudo kextload -v speedit.kext

Type your password when prompted, then voila!

Oh and, when you want to unload it for various reasons, type in:
sudo kext unload -v speedit.kext

Oy, oy, oy.

If you’re going to run this marginal software, for god’s sake don’t leave it running, especially on battery power! It’ll run you batter down far faster than any of the so-called whine-stopping fixes. It genereates excessive CPU load and constant disk activity (that will prevent the disk from spinning down, e.g.).

Get some real utility software. Use Bresink’s Hardware Monitor or Temperature Monitor.
