Topic: Question about adding a specific fan (Read 1020 times)
It's the $110 Sapphire so ill try on top and ill experiment in a few places I think might help
What type of cooler are your 5830's using? If it's a turbine-type cooler with intake on the rear (the end near your drive cages) of the card, I'd position it blowing into the cards there. You'll be able to turn your GPU fans way down, it may actually extend their lifespan.
If it's a 'blow everywhere' type like the Saffire 5830's that exhaust out both ends of the card, then positioning so it aids the intake fans will have a similar effect. I hate this cooler design for mining, as it's dumping heat all over the inside of your case.
+1 on researching pos vs neg pressure - normally it wouldn't make a big difference but you're going to be pushing a huge amount of air. It may be worth trying to setup a postiive pressure system, theoretically allowing the GPUs to more easily pull air through the fans, across the heatsink, and mostly exhausting heat out the back of your case where it belongs.
Experimentation is really the key, play with positioning until your GPUs get chilly, and fly with that.

Another question is if I put the fan directly on top of my 5830's would it ruin the fan motors on the gpu's?
Would it be better to have this fan sucking air away from the case or should it be blowing air in?
Say you had a really big enclosed case that was ~3 cubic feet in volume.
You'd be replacing the air in the case ~80 times every minute at 240cfm. I'm thinking it doesn't matter much
The case is semi open. The lids off and the power supply is outside the case. Heres the case if it helps http://www.newegg.com/Product/Product.aspx?Item=N82E16811129066

Read up on positive and negative case pressure. The posts about burning out fans if the CFM's aren't equal are not true, assuming that your case isn't a PoS. I've have about 2.2x output CFM than intake on multiple computers for months and all the fans are fine.
62dBa is *really* loud
I'd be careful with placement, 240cfm is going to disrupt any other fans in your case that aren't as powerful - ie, if you use it as an exhaust your intake fans will be struggling to keep up. As an intake, your exhaust fans will be struggling to keep up.

Not if you use Deltas on both sides
62 decibals is still softer than a 6990 at max fan speed.
These would be great for an open case arrangement, but with an enclosed system you'll have to be careful about having both intake and exhaust being similar configurations or you'll burn out fans.

Ok so the fan in question is this:

I recognize that it is loud but I'm curious if any one has one similar to it or the same one and if so how much of a temperature drop did it do?
thanks.
