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 want a regular fan to do this so my radiator is self cleaning, blowing it out backwards while vacuuming it from the front is a pain, specially while it is running.

I hope they offer a way of disabling this "feature"

This will prevent some fan death as it will expel the larger chunks of dust to a degree, but the fine stuff tends to be pretty sticky. Needs compressed air. Also that style of fan is the one least likely to die on a gpu. The fans that really need cleaning are those blower style ones on slim profile cards. Those are pretty much the only fans I've seen die on a card and it's always related to clogs. As for throwing dust into your case I'd rather wipe out the bottom of my case than pull dust balls out of my card with tweezers.

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 !
Never mind the fans will not work as efficient in reverse

Wonder when they will start shipping cards with this "technology" in it.

Now I know I saw this feature on a card like 2 years ago. Seriously. I'm pretty sure it was on a Palit card.

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;)
and since i use sleep mode and never restart my PC...

Dumb idea

I think this "feature" is a dumb idea for all the reasons brought up in this thread.

However, for me, the real killer would be the bloody noise. 30 seconds of loud, irritating fan noise is too much, especially if you're in a quiet environment while other family members are trying to sleep.

And what about when I'm restarting my PC multiple times for troubleshooting or installing Windows and patching? This thing would be making noise all the time.

Mama mia this thing would drive me mad! :banghead:

Can it be switched off?

Off late, MSI has been at the forefront of graphics card innovations.
should it read, "of late," ?

thats the first thing I noticed, but it always brings a smile to my face to hear blokes jump straight to fart jokes, blowing jokes etc. warms my heart :)

Personally I love blasting my pc gear with compressed air every so often, it's .... satisfying.

Finally a Graphic Card with the proper amount of suction.

The only card that can be dust free is fan less. What we need is special coating that would repel dust. I belive we need better chipset that will generate zero heat = zero wasted energy

Why wouldn't they ?
