I'll start with the positive: tiny size, silent operation, good performance. It is essentially silent in a mini-ITX case with an i3 processor, and the temperature did not rise above 55 degrees under full load. The bad news is that the cooler base just does not extend to the CPU cover due to the terrible mounting on the 1155 socket, the threaded bushings being 1 mm longer. I needed to toil. The sole is precisely bent, with a 0.5 mm deflection in the middle! To get a plane, I had to pound on a piece of glass. Overall, the cooler is fairly effective, but the number of movements required to achieve this effectiveness is a little excessive.
