I got it because the M2 was "boiling" under heavy use, despite the heatsink of m/g Gigabyte. It contains 2 blue strips (thermal conductive with 2 protective stickers on them), and a thinner orange strip (with a sticker only on one side). The instructions mention a thick and a thin one. I put in the 2 blue ones, but it just wouldn't fit at all. With one blue and the orange, it required HUGE pressure for the screws to "find" the holes, and I managed to screw in only one side correctly (2 screws). The other 2 barely screwed in crookedly. Nevertheless, it does the job. The temperature is quite decent, with the fans at maximum (I don't know how to measure the temperature of the M2 with any program, it's not available in the BIOS). It remains to be seen when the mini fan will "give out." I don't think I'll find it anywhere; it will all go to waste when it breaks down.
