In this tutorial I show you how to install an AMD CPU (FM1, FM2, AM3, AM3+) and boxed cooler on a mainboard. Always make sure there is thermal grease on either the CPU or the cooler. If not, apply it before you assemble your computer! Don't use too much, just a "pea sized" portion on the middle of the CPU; it will spread when you place the cooler. You can also spread it yourself with an old creditcard. There are videos to show you how; in doubt, first watch a video about applying thermal grease and/or paste.
This video was shot with my "Samsung Galaxy Note" in HD 1080p.
