66.5 dBa?! You have any idea how much noise is it going to generate???
Less than a 6990. I measured 88.6dB at 100% fan speed, lol.
It literally sounds like a jet takeoff.

I'm really not trying to spam anyone, and I encourage anyone to grab these anywhere they can find them, but the tiny risers I found make about a 6C difference by staggering the heights of the cards. By letting more air move around the cards, and letting some of them directly suck in more air by being higher than their neighbors, it works really well. It's harder to use if you're using a traditional case because the cards can't be screwed down then, but it made a big difference for me.
Using two 12cm Fans, both lying right on top of the cards, blowing air into the gaps. I'm getting 56 - 74°C, all cards OC'ed from 800 to 950Mhz.
+1 just put two or three fans right on top
You should space each card with some foam or random stuff you find :O
If you are using a case, take the side panel off and get a fan (those standing square ones are best) and blow straight at the cards. Lowered the temps on my 6990 by 15C.
If you are going caseless, put 120mm fans on top of the cards, and other standing fans around it. Go look at the mining rig pic thread for more reference.
Make sure the room the rigs are in has good airflow. I put mine next to the window.
Good luck!

Atleast i do, Yes, 66.5 dBa
In all seriousness tho:

That is about as much as normal conversation.
Currently at my workstation the noise level is probably plenty above 66.5.
A 6990 at max load is like 70-80 decibels. :O

I had a similar problem with 4 5850's in a case,
I bought 2 PCIe extenders (kinda pricey @ $25 each, but you got to take care of your tools as my father would say.)
and built a aluminum bracket and my temps are now way cool. from 88ºC down to 60ºC.

That wiring job just screams fire hazard.

And just let this sucker blow on the cards?
If the case is going to be closed (with this fan as a side intake), you'd need to improve outflow as well somewhere else in the case...
MOAR FANS. or open the case, and point a big fan into it. If the case is going to be closed (with this fan as a side intake), you'd need to improve outflow as well somewhere else in the case...

No, Jack, don't discourage asbestos use. If other miners get mesothelioma then that leaves more blocks for me.
(Kind of ironic here how we're bringing in the risks of real-world mining to virtual mining.)

long time ago there was asbestos liquid spray if you can get something similar just spray on the back of your GPU if you dont have any other alternative just put a piece of glass make sure the fans dont touch the glass
that only insulates each card from each other. the heat produced and dispersed is still the same, so that doesn't fix the problem at allAsbestos has been illegal for over 30 years in most countries, google it.
If you go into a room with asbestos (let alone spray some in your near vicinity) you are increasing your risk of fatal cancer by a factor of about 100,000. Not really a good idea.
Yank that mobo out of the case, build a two-tier chassis out of angle aluminum or wood, and take two of the cards off the mobo and put them on adapter riser cables. That'll free up a lot more space between cards and give you a lot more room to run fans. If you already have a bunch of spare wood laying around like I did then you're only out the cost of the cables, which ran ~$30 in my case.

that will stress the PCB/PCIe connectors

As you asked for a quick and dirty solution: have you tried putting two 120mm fans onto the sandwich? They should blow between the cards in order to support the cards fans.

How much did you pay for the water colling system? Is it realy worth it?
