PC fans as intake?

[KieuVanQuan]

Would it make sense to flip my fans around and use them as intake instead of exhaust in order to like...suck the dust out of my PC?  I don't have an air compressor either + I cba to clean my pc always.

Never thought it would be relevant but anyway, here you go:

I would go outie, much exhaust and let it passively suck in air through dust filters.

Not ideal but that will give you the least amount of dust, at least that's what i concluded from it.

All dependent on what case he has though.

Yeah you can and it worked in the video above but I wouldn't recommend it if your doing a lot of gaming or high end tasks because you are significantly reducing airflow. Remember that even if you have an open spot where there isnt a fan such as at the top or bottom of your case, there is going to be a lot of dust build up anyway. This is shown in that video.

 

Personally just get more dust filters and then you hardly have to clean your PC. Also, you could just not clean it. Why does it have to look good? I clean mine only like once a year if that.

For cleaning dust that won't work. Normal case fans don't have enough pressure to move dust fast or efficiently overall. They are designed against such as in normal operating you want more air and less dust to be moved.

 

Plus the fact that dust inside case lays on areas where there isn't active airflow or that may have some static charge to keep it as flock.

true. But in the video there was less dust with all fans as exhaust

The point of the video is to compare how different fan placements affect on gathering dust. In which it succeed. They didn't compare performance (which would show that all exhaust performs worse than with some intake).

Because the case had decent dust filters...

Yes there would be a performance hit with cooling in this configuration
