Definitely it is not a good sign. Try to reduce it. On running virtual machines in any laptops (using i3) will probably overheat your laptop and also makes your fan's speed to increase to improve the cooling rate.
To solve this issue the driver which you installed is not the solution. Because it may cause your fan to undesired effects. Your problem may be due to the RAM capacity.
Before RAM upgrade
I used my lenovo laptop using i3 3110M ivy-bridge processor with 2GB RAM, 1GB dedicated NVidia graphics processor for running High-end games and virtual machines which made overheating of 70 to 78 degrees of Celsius with high-speed sounds from fan.
I came to know this will seriously reduce the life of the laptop. After searching many forums and websites i found that increasing the RAM capacity will not only boost the performance and speed of the system but it will also increase the life of CPU due to overheating.
After RAM upgrade
After upgrading the RAM capacity of my laptop from 2GB to 6GB system became smoother and the temperature reduced to 54 degree celcius which is normal.
Normal CPU temperature details can be found here. Your laptop is probably ivybridge. See its range.
I advice upgrade your RAM from 4 GB to 6 GB or 8 GB for usage of VM(Emulators also) and High graphical purposes.
