Putting a small case fan above a double-fan GPU in an SG05 is a good idea and will help with temps, because it will create a negative pressure space for the heat off the GPU to flow into. I had a Scythe mini Kaze 40mm doing just that. It made about 5C difference when folding.

However... wink.gif

It doesn't work like that. The CFM rating is measured when the fan is entirely unrestricted with 0 pressure difference between the space behind the fan and the space in front. As soon as the space behind the fan is closed (ie as with a box) then you have to calculate or measure the pressure curve which isn't trivial but depends on the pressure curves of all the fans, the size of the box, the surface area of all the openings, and the proximity of the openings to each fan.

Think of it maybe like one of those kids' roundabouts. If it's just you pushing it round, it'll start slower but eventually you'll get it to a good speed. If three of you are pushing it, it goes faster but not three times faster, it'll just be a bit easier for each of you to push.

Wow.

Will that Galaxy DF 670 fit in the SG05?
I would think it's longer than reference length...

(on the go atm; can't look it up)

I guess, although I see it taking all the air that the dual fans intaking from the radiator will blow towards it. Might not be as much air as I originally thought, but a lot none the less. And the sugo is very well ventilated so I wouldn't imagine there is a lot of pressure to exhaust heat. Also heat rises, so that would at least pull the hot air from the top of the case. Idk, if I buy the fan, which will most likely happen once I get my gift card from newegg for buying a 3570k and tt water 2.0 performer I will order the fan and check the heat difference.

Yes, it will work exactly like that. As I said, it's a good idea and I know from my own experiment that it makes a significant difference. I removed my mini kaze though because I stopped folding GPU and tbh it was a bit noisy smile.gif

Also, Stealthybox, the Galaxy 670 GC will fit, should be with 4mm to spare.

Yeah, and the galaxy gtx 670 dual fan will fit I believe. That is the gpu I am getting some time soon, have to make sure I can get the 4gb though, its 10 dollars cheaper than the 2gb for some reason.

Anyone else have to made their Corsair H70 brackets to get it to fit under the motherboard? I have to do some minor cutting for mine.

I'll try and post a picture or two tomorrow. thumb.gif
