The size is used to, I myself had not at first made sure I had the fan already considered as large. After opening the package there was also an "Oh, dear" ... the whole cooler full 17cm high. But he still fits in my geradeso housing.
Installation is also easy. Probably because my order was a returns, it was the wrong instructions, but it has all worked out anyway. The only sticking point is just only that the board needs to be removed, at least for AMD boards.
