    Very compact low profile cooler, quiet and efficient operation. Some challenges to install though.
    The Cooler Master GeminII M4 is a CPU cooling solution that was purchased for an Asus P9X79 Pro motherboard with an Intel 2011 CPU socket form factor. Due to the layout of components on the motherboard, accessing the fastening screws is nearly impossible. In order to start the screws into the threads, a small amount of downward force is needed on the heat sink cross bar. The heat sink is held in contact with the CPU by tension on the fastening crossbar (like a flat torsion spring). So installation with the supplied open end box wrench was not really possible. I think this would have worked if the entire mother board was removed out of the case on a work bench for the heat sink installation. Not a very practical procedure on existing in service mother boards. My work around involved using a long metric allen driver and inserting it between the aluminum fins down on to the fastening screws. The four screws have a hex allen slot that made this possible. This is a viable and a much easier method of attaching the heat sink to mother board socket. The procedure required removing the fan assembly from the heat sink. I'll include pictures if I can upload them. I recommend allotting time and patience to complete this project.The only downside is that some memory types on this particular motherboard may not clear the lower heat pipes and heat sink fins. Its a a very tight fit next to the memory modules. See my attached picture to see what I'm referring to. You should go to the manufacturer's website and check details about this before buying.With everything installed and put back together, the result is a nice looking, compact, and quiet fan assembly. I recommend this product as it is quiet and light weight. Ideal if you have to ship your PC around the country. Having the fan assembly compact and out of the way is helpful when servicing and removing other components from the case. I'm definitely going to buy more for my other computers that have noisy CPU coolers.
