The fans are very empfehelen for people looking for the glowing 120mm fan. The brightness is good and very quiet Laufer !! Have 2 installed and it really is a friend quieter computer. The rubber mount is ok and makes a quick assembly possible. For the page range of a computer but I have these removed and since then, unfortunately missing spare screws for fixing. All in all but a very quiet 120mm fans in red ^^
