Solved Irregular fan speed

I purchased a Windows 8 laptop early last year and have had minimal problems up until recently. A few days ago, when running a resource intensive game, I noticed that the fan on the side of my computer would randomly become louder, then quiet down, then get louder again. I checked the system monitor when it would speed up and it showed that the fan speed jumped from about 76% to 90%. This has been happening whenever I play strenuous games now. It would not concern me as much if my framerate on these games would not also decrease randomly as well. If anyone knows of a solution, please inform me.

That means your Laptop is getting over heated.
Use a vacuum cleaner to suck out the dirt on the bottom of your Laptop where the fan is located or you may have to disassemble to clean it real good.

Thank you, I suspected over heating myself.
