    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.
