MSI Develops Dust Removal Technology for Graphics Cards

Of late, MSI has been at the forefront of graphics card innovations. The latest is what the company refers to as "Dust Removal Technology". Dust buildup on the surface of heatsink fins can reduce cooling efficiency. Without giving us too many details about its testing, MSI claims that a clean cooler can keep temperatures down by as much as 15°C. Dust Removal Technology uses a simple method of running fans in the opposite rotation, drawing air from the heatsink and pushing it out through its intakes, with 100% fan speed for 30 seconds at system startup can work to reduce dust accumulation in the tough to clean parts of the cooler. Since the "dust removal" happens on each system startup, cleaning happens on a very regular basis. MSI plans to implement the Dust Removal Technology on all its new and upcoming graphics cards.

I'm not sure this will work. It will probably just build dust up on both sides of the fan. I could be completely wrong though, I spent approximately $0 researching it.

Looks interesting, but I doubt it will be able to repel all the dust.
If they don't increase the price of their cards because of this, it could be a nice little touch to make their cards a bit more wanted :)

The Gigabyte Windforce coolers are also advertised as dustproof apart from being silent.I have a windforce gts450 right now so i'll probably find out if it's effective or was just pure advertising.

Only one real issue as I see it..."with 100% fan speed for 30 seconds at system startup"

So this system only works for those who shut the PC off every night.

Seems the longer it is between cleaning cycles, the less effective the system;)

It would probably happen whenever the PC restarts too, but as someone that leaves their PC on permanently, and only restart when i need to, this wouldn't work too well as you say...

The problem isn't that normal fans can't suck out the dust, the problem is that dust particles stick to the heatsink's surface :rolleyes:. Could do better with inventing a paint that is 100% smooth and has the same electrical charge as the "dust". Physics one-oh-one, likes repel !

It's been ages since I shut down my PC. And I'm sure most enthusiasts keep theirs running for months !

nonsense on: no, unless you fart outside-in!?

nonsense off: Asus latest cards also have it, maybe more silently.

So Asus fart is more subtle?

Close. More like a cat trying to cough up a hair ball.

And I agree it won't work unless the fans regularly reverse spin, like maybe every 12 hours?

100% fan speed for 30 seconds seem like taking drastic measures, usually the noise of a fan running at 100% is everything but quiet

Won't work. Just blows dust back into case; deposits it in your other fans and components, it will suck it back up, eventually. Did they develop they DVD Rewinder, too?

Now, when they enclose a maid in each box to do some case cleaning for me... That will work and I'll buy into it.;)

Who knows ? If it's running in reverse, it might suck noise as well :laugh:

Speaking of reverse running, wouldn't this method only ditch the dust into the other components ? Would be a pain specially if you had a couple of cards on SLI/Crossfire. Dust sticking to the back of a PCB isn't a pleasant sight

Take experience from server systems...
To be able to remove dust, you have to have huge airflow and pressure (server fans are capable of making a small hurricane).

Running backwards at 100% is a good idea, but only if that 100% is really powerful.

Yes, it will fart dust. Good luck with that asthma.

To me its stupid unless it expels the dust OUT of my case. Not all over my mobo and CPU heat sink. I mean I don't need a GPU that just $h!ts dust all over the rest of my components.

I would rather my GPU old the dust in like a tight sphincter until I clean it out as I see fit.

EXACTLY. It's just going to blow all this dust and dirt all over the case and probably get sucked back into the video card. It might a bit but this is more of a selling point than anything. Keeping dust out of the case is a better investment than paying more for some feature like this. I guess if they're not charging any extra it's not an issue though. At least they're trying to improve things =/

Yet people thinks the Fan on reference ATi cards are noisy :laugh:
That is the kind of fan the work-station cards use.
The fan on my 5870 only goes to 4800RPM, I have seen more powerful ones.

Even if it does work it just blows dust into case and create more work for case fans.

as far as im concerned, there is no better way to deal with the dust problem then taking the graphics card out and giving it a few blasts with some compressed air.

I'll stick to that approach.

Not just fart, but fart dust... :roll::roll: I can hear it now.. Your video card is so old it farts dust! :roll: :roll:

EDIT:I wonder does it sound like PEW PEW PEW?... LOL
