Cons: The mounting hardware is not easy to setup and if you are trying to use the hoop mounting set then it doesn't give you much room to move the heat sink around, you have to almost dead on or you can use it.
Pros: BIG heatsink, dissipates lots of heat, just make sure you have the room for it
Cons: I have a ga-ma78gm-s2h motherboard and the j-shaped mounting hardware simply do not reach the mounting the holes, even from the every edge of the rail. I had to make my own longer version of the j-shaped brackets out of some stainless steel scrap metal. After installing these, I still don't feel ...
Summary: I have installed 6 heatsinks and this was the only one i had any kind of problem with installing. You have to line up the screws with your MB's holes but without the screws falling out of the socket they are in.
Pros: Fanless, but still managable tempatures for NB.
Cons: 5C hotter then stock cooler, very flimsey even when installed correctly, problems with many vid card and MB combos, SCREWS AND NUTS ARE EXTREMELY EASY TO LOSE AND YOU GET NO EXTRAS, the installation is horrible.
