Heatsink idea

[Deckham]

Just a little idea I was mulling over this morning - what do you think?

A tower-stack-style CPU heatsink, with 2 80mm fans mounted vertically and opposing each other - 1 blowing inwards, the other outwards. Outward blowing fan attaches to 'heat-tube' which exits case.

Noisy perhaps - but initially it feels like it would go a long way to cool then exhaust hot air.

Comments?

Oh?

Well, that's what usually happens to me

Would you care to point out which 'ones' you mean?

True Demo24. The theory he has though was found to be inefficient since the fans create a useless vortex if they aren't matched perfectly, which is also impossible. The manufacture (name slips my mind at the moment) stated both fans should being going at each other or away from each other (best efficiency).

If they were 'aiming' at each other, wouldn't that cause a vortex/turbulence?

I was thinking of a system that would effectively 'drain' hot air from the heatsink to outside the case.

I understand that the exhaust fan would need to be slightly higher cfm due to the heatsink interrupting the 1st fan's flow - in this scenario, fan2 would be assisting fan1 to draw air.

If the unit was enclosed except for inlet/outlet, then the only passage for air is through the heatsink itself. The enclosure would also reduce turbulence noise.

That link shows a single-fan style HS with heatpipes - not what I was describing at all.

no another fan goes on the other side

I saw something similar once where someone took a Zalman 7000 and removed the fan and placed a tube over it then put an exhaust fan at the back of the case drawing the air throught it and out of the case. IIRC it worked pretty good.
