Query: Worked for me.. Didn't melt but LOUD!!!

Forgive the short review but the subject pretty much sums it up.. Mine actually helped in terms of cooling and made a noticeable difference but it is so ridiculously loud brand-new out of the box you will be debating if you even care to use it. Then after a few months when the bearings in the fans get dusty or whatever, it gets REALLY loud.. After it runs for a while it quiets back down but still inexcusable in an era of bearing-less fans.Not recommended.
