This product is really excellent. Diverted from its basic purpose is to use it as fan heatsink, this fan was placed in the extraction case and performs wonderfully his job on a machine "gamer". The price really justifies the quality. The only problem, the silicone attachments that I would not have managed to use, either by incompetence or by the real difficulty in placing the This-said the bundle also provided a set of screws. Question noise, the quiet. Even pushed to its limits the fan does not exceed the noise CPU cooler or graphics card. Very good in short, not to hesitate if the budget allows.
