I bought this fan a while back when I first modded my x850. Cools extremely well. For aestetics purposes, the fan has red LEDs. Well after about a month or two, I noticed the LEDs weren't as bright or working as much anymore. I took a shot and requested an rma on Zalmans website. Never got an emal, never got a phone call. To be honest I forgot about it. Until yesterday. In the mail was a replacement fan. Not the ENTIRE product, but the actual fan. No documentation on sending the other one back, just the replacement product. I am happy with that because it will illeviate my problem. You dont get to see the fan or the red heat sink blades much because of the ususal underneath orientation but if I pay $40.00 for a fan, I want every aspect of it to work. Here is the link. Just wanted to express my satisfaction to those who were interested in these products. Have a great weekend.
