The Graphics Card That Cleans Itself
Dust-Be-Gone!
Dust inside your graphics card can be a real killer. Not only can built up dust reduce heatsink and fan performance, but continued accumulation over time can lead to a total failure of a part.
MSI claims it can solve this issue. The company's latest graphics cards are starting to sport what it calls "Dust Removal Tech." Clear and simple! Essentially what happens is that when you start up your computer, the graphics card will operate its fans in reverse mode, pulling air away from the heatsink instead of blowing air onto it. This reverse fan movement is suppose to draw out clogged up dust.
Unfortunately, the air and dust gets blown back into your PC. At this point, one will be hoping that any aux fans or the PSU will be able to remove the dust from the system. After 30-seconds, the graphics card will switch to normal mode.
We can see this possibly working if you turn off your computer after each use, but most tend to leave their computers on for long periods of time. Some users never turn off their computers at all.

Anyone knows if my supposition is correct or not?
Anyway, it seems like a nice try to solve that simple irritating little problem
Cheers!
Edit:
Not entirely true. I turn it off to take it apart and clean it with an air compressor.
Yeah, but I'm sure there's a sensor so that if the core starts being loaded the card will bail out of the reverse mode and switch to normal operation. Or if there isn't some MSI engineers need to grab some frisbees and commit seppuku.
Also if there is humidity involved I question if the dust would be so easily dislodged.
No problem whatsoever. The thermal mass of the heat sink can easily absorb this heat if it starts out at room temperature.
Since this is only used (as far as I know) on their Twin Frozr III heatsink, I'd day that it can nearly run cooler than a reference cooler with the fan in reverse ALL THE TIME, let alone just for 30 seconds to clean itself. Now, that was an exaggeration... or maybe not... but either way, you get the point. The Frozr III cooler should be more than capable of handling things.

I use my compressor regularly for cleaning up the pc and components. Several models are available and small enough for apartments as well.
If moisture is a concern, there's an attachment to your compressor's hose that catches any outgoing moisture.
Where I live, you have to either cover your car, or wash it 3x a day just to keep it nice. Even with filters on the intakes, it still gets in there.
Unless MSI's system is really quiet, you won't be impressing anyone when you start up your pc. You might scare them instead hehehe
Would be better if it picked up on a point where the thermals where low and reversed based on a daily time, or something like that...
