Very easy installation of heatsinks on Rasberry PI 2 as it is bonded to a sehrdünnem 3M double-sided tape, which means you just the other side must make the protector down and correct centering on the block and it was. Caution Only do not be surprised who buys this heatsink for the Rasberry neursten PI 2 B has only 2 chips you can paste over a third smaller heatsink remains. The two small heatsinks are equal, so what sausage it takes. Although there is a third chip at the bottom but is not meant firstly not no longer goes there view from the height then and secondly, which is a little larger than the heat sink of the left, perhaps for previous model of Rasberry Pi of 3 chips had. Yes otherwise there is not much to write because it's a pretty simple part of the function has has to dissipate the heat. Let's see the long-term test to now 100% satisfied. I'm going to write a recession later and report my experiences.
