I bought it to cool my I5 processor 750, to replace the original fan (5770 graphic card). Nothing to see. It fulfills its role very well and stabilizes the temperature to about 50 °. The only drawback would be the noise. You hear it working well but it's not unbearable. Personally it does not bother me more than that. Very good value for money. The small downside to the facility that is not practical. Anyway, once in place, we forget!
