MSI unveils self-cleaning graphics card

Component company MSI has detailed its latest exclusive graphics card fan technology - it packs a number of new features, the most interesting of which is its dust removal technology. On booting, the fan runs backwards for thirty seconds, sucking out any debris that may clog the heatsink.


It seems they estimate that dust in the cooling solution can insulate component to such a degree that it can raise its temperature by 15°C, which can be a major cause of crashes (which I'm sure many of us have come across), so they've come up with this to help. They also say the design of the fan, which has "arched edges, grooves and a gloss coating" and can give a better airflow, to the tune of 20%. Apparently, the fan also changes colour when the GPU runs too hot! :D

They're planning to release this first on their model of the Nvidia N580GTX.

That is interesting.
It is good that they are still trying to be creative and not just saying, that's good enough.

A few thoughts though.

If a fan is directional, they may have to redesign a fan that blows air in two directions, so it is effective backwards.
it seems like it would be effective on lint, more so then dust as from experience, it takes higher air pressure to remove the dust, not just a fan spinning with X amount of cfm.
Keep in mind that you now just dumped dust back into your case to now be absorbed by every thing else, psu, cpu and video card again.

But at least it is a step in self preservation for those who don't take care of their own electronics.

I see it as mostly a gimmick.

The circuitry/programming to define which way a brushless fan spins isn't new of course, but it will add a tiny bit more to BMC...something manufacturer's hate unless there's a real advantage to it that will result in more unit sales.

They'll have to give it a real sexy-important sounding name."Now with CPU Fluff-B-Gone" just won't cut it.

Maybe something like Radeon/ATi Video Cards' "Ruby" will help motivate consumers? She'll fight that nasty dust for you!

Or Nvidia's Adrianne (have to give equal exposure, right?)

However, implementation may increase the time between deep cleanings but won't eliminate the need for them. Probably most useful in a difficult to access fan (like notebook fans...which are difficult to access mostly because of case design needs).

It won't replace either routine deep cleanings or the need for users to monitor temperatures and manually cleaning when the temps begin to consistently trend upwards.


I wonder if a "teflon"-like fan blade coating would be more or less effective? (but, might be too easily damaged by handling). Same thing for any heatsink coatings or manufacturing changes...they run the risk of being too fragile to survive "normal" hobbyist handling and cleaning and could quickly lose effectiveness...like camera lens coatings and 1/4 wavelength display anti-reflective coatings.

That is a good thought. I had never thought of a fan blade being anything but plastic/steel/aluminum. But there does have to be some material that is anti-static, or can be negatively charged.Perhaps go back to the old wooden ones, though cutting through the air should still add a static charge. Perhaps a pre filter that is charged to help pull the dust out of the air.

Perhaps grounding the pc case to ground would help.

On second thought,i am going to start spraying "Static Guard" into all of my coolers and see if it helps :/

An ion anti-static generator and/or an ionic collector/filter, or maybe even just a high-power HEPA filter inside the case might help without impeding air-flow at the air vents or heatsinks to any significant degree.

Higher Humidity?
Just keeping humidity higher (25-30%) will help reduce static charge build-up significantly in some homes, but too high and it would probably start aiding the dust build-up.

External Room Air Filter?
By the way, I use a HEPA air filter in my room and it "just happens" to be in front of my computer. It does seem to have reduced the frequency I have to clean the computer filters and guts...but I can't really quantify it as I haven't kept cleaning records. Of course it also adds noise to the room.

Canned "Air" to Clean Computer?
I also have to seriously wonder about the "bittering agent" in some canned "air" cleaners. The thing that makes it taste awful so people won't intentionally inhale and abuse it.

I have VERIFIED the foul-tasting agent remains on computer parts for many MONTHS after using such a product. I thnk it's a dust attractor. It may even be based on an organic plant oil of some sort (so it's "safe") and mixing oil and dust is just plain BAD NEWS. I've stopped using any canned "air" cleaners that contain any "bittering agent".

OK so soak a paper towel and tape it to the case bottom below the VGA fan. The reverse will blow the dust into the damp cloth and stick. plus it will give you your higher humidity. can we name it after my first wife. "nVidia introduces Barbara. She sucks as good as she blows. See peep show video for details." or build a case with integrated strategically aimed duct work and a small air compressor. Fire it up once a month with rear panel switch, hit the button when it's charged and it delivers one super blast inside the case. THE RONCO BIG BLOW CASE! As seen on TV $19.95 plus S&H. But wait. Order now and get a second Big Blow Case ABSOLUTELY FREE (Just pay the additional $75 shipping and handling). Order yours today. Barbara is standing by to take your call.

EDIT: Paper towel thing not a good idea if you have one of those PSU on the bottom cases.

Get Hippied out!

Don't forget you can also pay with Ronco's Easy Payments for the Blow-O-Matic PC Case. ;)

"Now how much would you pay?"
"Not $100 dollars, not $90 dollars, not $80 dollars, not even $70 dollars..."
"It's just 10 Easy Payments of $19.95!"
"Remember, you can set it and forget it!"

LOL, despite it's outrageously cheesy, that guy's infomercial lines really stick to your brain. ;)
