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.
