I installed this on my Toshiba laptop with a centrino cpu. Promptly locked up the machine, and required a re-boot.

Has someone tried monitoring the Voltage readings? I find that the -5V and -12V readings are not where it has to be. Is this a problem with the tool or is it a problem with the power supply itself?

I'VE ALWAYS USED IT AND NEVER FAILS TO ACCOMPLISH IT'S TASKS FOR HD HEALTH AND PERFORMANCE.

Quite a perfect one tool. Very easy to use, with little bugs, it's a tool indeed - small, sharp, smart. What else do you need? I think it's really worth using.

I am using this program to silence my fans and undervolt, a term rarely used, to minimize heat generation. I love the feature that allows for automatic clock control, similar to the speed step technology found in laptops. Highly recommended program, and it's FREE, but definitely deserves a donation to the programmer.

Only voltage control is missing

Great little freeware program that even a novice like me can master. Problems associated with it not reducing fan speeds might be solved (they were for me!) by clicking on Configure;Advanced;select your chip from the drop down list (eg. IT8712F in my case) and bring up its details, then highlight PWM 1 Mode, PWM 2 Mode and PWM 3 Mode respectively and change it from ON/OFF to "software controlled" and tick "remember it".
This worked for me having spent a long time configuring it only to find that it did everything it said it would but then the fans just kept on going at full pelt!!!
The help files and setup guide (accessed by simply pressing F1) were easy enough to follow, though the screen shots are from an earlier version.
If you want it to launch at startup like i do, you'll have to put a shortcut in your startup file. You can monitor your cpu temp in the system tray if your nervous about using the programme.
Another tip is to initially run the program and observe all your temperatures for a while and set it up to let the ambient temperatures rise by just 5-10 degrees c or so, to safely monitor its performance. when your then happy that your not going to damage your pc, you can play with the settings to tweak to your desired levels.
The options button allows you to customise the tray temperature to make it easier to see, and if you hover over it it gives you all available temps!!
Also right clicking it allows you to restore/ minimise or close the application...
Check with your chip manufacturer for safe temperature ranges for your cpu before you start and try and stick well within them to avoid costly breakdowns!!
My main reason for running was to quieten my pc a bit, but it wont reduce noisey power supply fans!!!
Overall i find this FREE Program fairly usefull and reasonably user friendly though i admit it took me a while to get my head round it! Defonately worth a try, and theres an un-installer included on the start menue. ENJOY!!!

Its a great program, and super powerful to boot! (Pun intended).

this is a great program, not a lot of features, but it has plenty and had all i needed

For a long time I was happy to use S.F. However - since updating Windows XP to SP2, I can't use the program anymore. It blocks my computer.
Can anyone tell me what to do? (I have the latest version, but that doesn't make a difference.)

Runs fine, varies speed perfectly. helps keep my system super quiet

my favorite soft for inspec

it's ok

It´s a light software, eficient, and the best it's a helpfull tool to over cloaking procesor
