MSI introduced a new feature it's adding to its graphic cards called Dust Removal technology, and right now it's only available on the meaty N580GTX Lightning Xtreme Edition add-on.
The fan Itself Changes Color  ;D


Essentially this new "tech" merely runs the GPU's fans at 100-percent in the opposite direction when the system is turned on,
expelling any dust from the heatsink fins and fan blades that may have accumulated since the system was powered off.
After thirty seconds, the fan will then resume its correct rotation and blow heat off the chip.

"Experiments show that cold air can't effectively remove the heat from the heat sink fans on a graphics card if they are covered with dust," the company reports.
 "The result is reduced cooling performance and the GPU's working temperature may even increase by 15°C! With the advanced MSI Dust Removal Technology,
the fans spin in reverse for 30 seconds upon system startup, helping to remove dust buildup on heatsink and ensuring optimal cooling performance."

It's surprising that card manufacturers haven't thought of this before, but you can bet non-MSI vendors will surely follow in the coming months.
 It will be interesting to see if this fan-reversal for 30 seconds will actually keep the GPU and its cooling components clean, or if it ends up becoming just another gimmick
to sell more cards. That said, the dust removal "tech" may not be too useful for those who keep their desktops powered up 24 hours a day, 7 days a week.

The dust on my GPU HSF's and CPU HSF don't blow off with the force that the fan can provide.  You can sit there and blow at mach 1 with your mouth and it still won't all come off.  Only an air compressor or can of air can get it all off.  This tech might help a little bit, but it's going to be [falsely] marketed as a 100% cure to the dust problem.

So let me see if I got this right. They say that a fan sucking air from the heatsink will clean dust that can't be removed with the fan blowing towards it? Who's the idiot who thought of that?

Don't know if anyone mentioned here or on any other forums, but imo this is idiotic. Point: For one, there is dust on the fan already, slowing down on cutting the air. Two, dust on the hs or w/e, you reverse that fan to "auto clean" blows all that dust up inside/outside all of your pc/over the place in your room. Shine a mag flash light, while doing this "auto cleansing" you will see all the dust particles every where.

Meh, I see only one way cleaning, that is take the PC apart, fans off and clean it the "right way". All the way up to using from a vacum (http://www.amazon.com/Metro-Vacuum-ED500-500-Watt-Electric/dp/B001J4ZOAW) to Q-Tips.
