Acer Aspire One D270 fan continuously running

I recently purchased a new Acer D270 netbook and observed that its fan is continuously running. Although fan was not making any audible noise at all i thought of using Acer Aspire One Temperature Monitor and Fan Control software even though it mentioned to use the software at your own risk I installed it on my netbook.

Now as soon as I ran it my fan speed increased 2 to 3 times the original speed. So, I uninstalled it and restarted my netbook. Now I am observing that even after uninstalling it my fan is running at a `faster speed(may be 1.5 times)` than when I had not installed it.

So, my question is why am I observing this behavior in fan speed and what can be done to reverse the effect of the software.

Constant high fan speed can be caused by a lack of graphics drivers. Did you accidentally uninstall them when you did this? You might want to do a System Restore to a time previous to installing that fan utility.

FliGi7,

No, my graphic card is working fine and its driver is also installed correctly.

I also did a system restore but no effect on the fan speed.

Go to Device Manager and see if there are any yellow exclamation points. You might try re-installing the software again (or another fan control software), setting the fan speed to its normal setting, and then uninstalling it again.

Occam's Razor: Are you sure the fan's not back to its normal speeds and you're not just more sensitive to the fan sound now that you've used the program and heard the increased fan speeds?

There are no yellow exclamation marks in device manager.

I am sure that fan speed has changed because earlier when my netbook was at 40C I was not able to feel any vibrations but now as fan speed has increased I am feeling vibrations from my netbook.
