Not even that they are just spitting dust back into your computer. Great...

How about just including a filter with all your fans? Or making the fans removable and easier to clean the normal way?

People reboot their system? That isn't very Linux friendly ;)

So a fan that can reduce the life of the components in your PC to allow itself to last longer? I think I'll pass on this one!

Its not just spitting the dust back into the pc, its shaking off the dust, to only have it sucked back into place 11 secs after booting up.

As with a lot of "new tech", this sounds great on paper, but in practice it just spreads the dust about and then sucks it back into place.

Bet the designer got a bonus in his wages for this one.....

Hasn't this sort of thing been done before, IIRC there was a graphics card that done the same thing?

As already mentioned, a fan that allows you to remove the actual rotating assembly relatively easy would be much more beneficial IMO. Countless time wasted hoking brushes and cleaning solution round blades after having removed the entire assembly.

it could be much easier

A brand new fan with a 10 second reverse startup is genius, it basically ensures it never gets dust on it, not "blowing dust into your pc." We're talking minimal amounts here.

Yep. MSI do it with their aftermarket twin fan coolers.

If it's on the front intakes that might be a good idea, not sure how well it'd work in practice.

Gotta test this one. I admit I am intrigued.

Thanks, I thought I was going crazy reading this article, thinking I'm sure I've read about this being done a fair while ago. I do indeed have an MSI GPU.

So how do exhaust fans work? Do they pump a load of dust into the case when you start your PC?

Meh. Barely any dust inside my case anyway - and I've got a dog :p
