I had originally bought this cooler when I ordered a Fujitsu n5010, http://www.x-tremegeek.com/templates...sp?T1=148+0752 but I had to send back the n5010 because of a dead pixel so I now use it for my new 4780. There is another review of the cooler by someone else in this forum and thats how I first found it. The cooler with the fans turned on did reduce the heat on the left palm side but it made a really annoying vibration so I rarely turned the fans on, that is until I modded it somewhat. I cut out some styrofoam padding about 6" in length,1" in width, and taped them on the bottom of each end. This worked rather well and the vibration was eliminated. It also had another benefit. By raising the rear of the cooler about 1", it created more circulation for the cooler's fans.
Now I don't have an internal thermometer so I can't tell if the temperature actually went down or not but what I do notice is that the left palm rest and left side of the keyboard are noticeably cooler and the fans on my 4780 don't turn on as often and when they do, the don't run as long.
I probably paid too much for it because I saw similar products for much less, but it does also act as a usb hub and all in all, the cooler does an adequate job.
