Attaching two fans together?

post #1 of 4
Thread Starter 
Hey guys,

I'm no physics major but I'd assume there may be some complexities involved when attaching fans together. For example:

[fan1][fan2]{HEATSINK}[fan3][fan4]

Does this type of set up help air flow in the least bit?

No, that would be bad for the fans. What you can do is use a fan as a shroud. Cut the blade and motor assembly out and save the rest. Example of mine:

Notice the fan housing that is closer to the cooler is the shroud, then the fan is attached to it, eliminating the dead spot on the heatsink, improving temps and reducing noise.

I see very little to no benefit from doing that. I think the first push fan will get the majority of the air blocked from the second push fan.
But I may be wrong.

You are correct unless the fans are counter-rotating. That's a whole different story but those fans are very expensive.
