Matt from the OverclockersClub has let me know that he's just finished his review of the Thermaltake 80mm SmartFan!!! I got to say Thermaltake make same great fans as I use the blue orb myself :D

So here's a byte from Matt's review:

I reviewed the Volcano 7 heatsink/fan a couple of months ago, which did very well I might add. The Volcano 7 heatsink comes with this same exact ThermalTake smartfan. Well today, I will be doing a specific review on this fan and getting in to deeper details about it this fan. [...]
Is the Smart fan here to stay? Well, it all depends. I think they are here to stay, but some things need improving...

So for the rest of the review warp to the Overclockersclub.com.
