[Discussion] Experiments in air cooling: More fans do not equal better cooling in all situations.

I made this crossfire build a couple months ago, and since then I've been trying different things to try to bring down temps on my graphics cards. This discussion is to illustrate the different things I've tried and how they've helped or haven't helped my temps. For those of you who want cooler temps and have the aftermarket GPUs that don't exhaust heat out the case, but can't necessarily afford water cooling, I hope this will give you tips to keep your temps down.
My build consists of two GIGABYTE GV-R797OC-3GD 7970s inside a Fractal Design R4 case. I use the cards for gaming and bitcoin mining and my temps were 69C/71C in gaming and 79C/77C in bitcoin mining. Now the gaming temps were fine, and I don't have a lot of time to game so that wasn't a concern. But my main concern was my temps during bitcoin mining which stresses the cards a lot harder than gaming. ~80C is ok for short-term but I was concerned about temps long term as the machine was on 24/7 doing mining when I wasn't using it.
This was my initial fan setup. I found that this was the best configuration with the fans that I had. I had 2 140mm intake fans in the front, 1 140mm intake fan on the bottom, and 3 120mm exhaust fans. I also had 2 80mm fans zip tied together. At first I put the 2 80mm fans so that they were blowing in between the two 7970s, but that didn't help temperatures. Before I placed the 2 80mm fans, I was getting 79C for the top card and 81C for the bottom card. When I suspended them so that they were blowing inbetween the 7970s, I got 79C for the top card and 80C for the bottom card. This was probably because my cable extensions restrict the airflow coming from the fans. I then put the 2 80mm fans where they were pictured, and got 79C for the top card and 76C for the bottom card. So this placement helped a lot with temps on the bottom card.
Of course I wasn't happy with that because I was still getting around ~80C for the top card. So then I tried this fan configuration.. I bought 3 140mm fans to replace the 120mm fans I had for exhaust. I zip tied the 3 120mm fans together and placed them so that they were blowing towards the CPU/GPUs and then I took the 2 80mm fans and repositioned them so that they were blowing towards the GPUs from the side. I also tried to reposition my cable extensions so that they wouldn't restrict airflow inbetween the cards (not pictured). With this setup, I was getting 76C to 77C for the top card and 75C for the bottom card. In terms of the 80mm side fans, I also tried pointing the 2 80mm fans so that they were sucking air away from the GPU, but this made the temps a lot hotter. I also tried positioning the 3 120mm fans so that they were blowing against the 2 140mm intake fans (makes no sense, but I wanted to see what would happen) and that made the temps hotter which was to be expected.
So in summary, if you want better cooling, you might benefit from adding fans inbetween your intake fans and your GPUs so that you get more air blowing on your GPUs. If you have a case with a side intake, these experiments might not apply or you might have to configure your side fan differently to optimize airflow. Some flaws in these experiments is that I'm not using the best fans for my setup. This pcpartpicker list includes my fans. If I really wanted the best cooling, I would have gotten the best fans for each size fan, but I couldn't afford it and hell, if I could, I would be spending closer to a water cooling setup. The fans I have listed, I already had, or paid $2-3 dollars including shipping for them on ebay.
Of course I still wasn't happy with my temps, so the next thing I tried was replacing the thermal paste on the GPUs. The results will be in another thread if this one gets enough attention.

Cooling for casual miners

I guess this might not apply to all in this sub because the more important things in a mining rig are adding as many cards as you can and blasting them with a box fan, but this might apply to those who have a primary PC that they also use for mining. This is a xpost that I posted in buildapc

Finally bought my new PC. Can't wait until it comes in.

Type Item Price
CPU AMD FX-8350 $199.99
GPU GIGABYTE GV-R797OC-3GD $399.99
PSU CORSAIR Enthusiast Series TX750M $124.99
RAM G.SKILL Ares Series 16GB $99.99
Motherboard ASUS M5A99X EVO R2.0 $139.99
Case NZXT Source 220 $49.99
SSD SAMSUNG 830 null
Fans NZXT FN-120RB 120mm Case cooler x 2 $8.99
Total (after the promo codes, coupons, etc, with shipping) $1010.41
I'll be using a couple HDD's I have laying around for storage, and I've had that SSD for a while, it's a real fast little drive. I decided to go with the 990X motherboard because it was cheaper than the 990FX board, and the 990X board had a combo deal going on with the 8350. The only feature I'll miss, really, is one SATAIII port, but 6 will be more than enough for me. I just went with the 990X board because of money, if I had a few more dollars I would have gone with the 990FX board, but I'm not too bummed about that.
Otherwise, this will be used mainly for running Linux VM's (and Mac OS X, I got it to work on my Phenom, at least) for Android development, and general Linux related things. Main OS will be Windows 7 Pro, I mainly play SC2, but now I will finally be able to play BF3 and War Thunder. Other than that, I do all kinds of things, it would be too long to list, but that and bitcoin mining, I'll definitely be utilizing this rig to it's limits. It should be here Tuesday or Wednesday, I'm so freakin' excited!
