dual fans

post #1 of 19
Thread Starter 
im sure this isn't new but i took a little epoxy today and glued 2 fans together ... and noticed a good 5* improvement in the temperature of my mobo and processor. the flow is much more powerful i was really happy with it. has anybody else done this and is there any "bad" that could become of it ?

Actually, it is somewhat common. The only thing I would worry about is having more intake than exhaust or vice-versa. This can create turbulence inside of your case and can result in a whole lot of dust intake.

This idea more or less only works for a 100-120mm fan. The smaller fans won't have the same air push. It would work best with a 120mm, me thinks.

isn't that what the 220 deltas are. 120mmX120mmX76mm fans... that's 2 120X38's stacked beside eachother. And if i remember correctly, the two different fans spin different ways. Let me see if i can find a data sheet.

[edit] here it is: http://media.digikey.com/pdf/Data%20...120x76.2mm.pdf

If you look at the drawing, you can kinda see way too many fan blades. that's b/c it's really two different fans.

Because the air is being boosted, then boosted again = extra spped (air becomes colder at speed)

Think about it, its like going 60 (adding extra gas) and going 100. You get more boost because you have more power. Not sure how else to explain.
