Thanks Heinz.
That's pretty respectable performance.

if you have FB-DIMMS on your server and you have some good ideas to cool them down, so let me know.

regards 

looking around I found in inquirer FB-DIMM with Heatpipe cooling a very interesting review.
I ordered now GEIL EVO Cyclone MemoryCoolingSystem
the mounting kit looks a little bit better, varying the high is important and 5000 rpm of the fan

As we can see the temperatures of FBDIMM1 and FBDIMM2 are 94 / 92 grd thats 7 grd higher than OCZ cooling system.
We see further that DIMM3 and DIMM4 have now 10 grd more than the OCZ system.
This means the one 5cm cooler is not enough to cool the FBDIMMS down, although the fan runs 4212RPM, thats 800RPM over its specification, very well, but its not enough....
Further we see my inner sensor which is placed between DIMM1 and DIMM2 shows 74 grd , with OCZ it shows 67 grd.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The EVO shows 41 grd and 4286 RPM on its LED Display. (After one and a half hour operation)
Out of my view the EVO Cyclone is more a funny kit than a very good cooling solution.   
Pitty, it fits perfect over the FBDIMMs.
And now the upper x16 grafic-slot are usable.
Here are some pictures:
EVO Cyclone mounted.
EVO Cyclone with additional fin-plate bottom for better airstream and that the fan not getting hot air from the graphic adapter RV670.
I mounted the additional finplate bottom(white) for better air-streaming from the fan sitting right bottom before the big cooler of the RV670. As you can see on left side 4 slot-plates are open now for better airstream.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Now after 4 hours and switch on a additional 28cm case-fan near frontside temps are:
DIMM   79 °C  (174 °F)
FB-DIMM1   92 °C  (198 °F)
FB-DIMM2   88 °C  (190 °F)
FB-DIMM3   86 °C  (187 °F)
FB-DIMM4   81 °C  (178 °F)

CPU1   662 RPM
CPU2   638 RPM
North Bridge   4900 RPM
South Bridge   4182 RPM
DIMM   4231 RPM
Aux   722 RPM

The EVO shows 35 grd C,   4136 RPM  on its LED
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
OK, I will run this EVO Cyclone cooler, but I must search for a better more effective cooling solution.
Lets everybody make his own conclusion. 

modify EVO:
EVO with tube
EVO look into tube
The EVO shows 24 grd C,   4050 RPM  on its LED
DIMM   79 °C  (174 °F)
FB-DIMM1   88 °C  (190 °F)
FB-DIMM2   83 °C  (181 °F)
FB-DIMM3   80 °C  (176 °F)
FB-DIMM4   80 °C  (176 °F)

CPU1   659 RPM
CPU2   652 RPM
North Bridge   4936 RPM
South Bridge   4157 RPM
DIMM   4157 RPM
Aux   935 RPM
~~~~~~~~~~~~~~~~~~~~~~~
my modification shows effect, from 92 down to 88 grd. (Case open)
I construct a tube, so cool air from outside the case can now come in.

[Raistmer]

>10C difference between edge memory slots?! Too big gradient IMO to call this cooling system good one.

on such a "hot" source a little H2O sometimes will be up to the job.

modify: picture tunneling, longer tube, better values
A full tunneling of the passive RV670 transport the heat out of the case now. (its all paper-maché to see if it works, will make it later from any plastic thermo-isolated material)
The tube is now 21 cm. Case is open.

A better solution would be a cooling-unit with 3 Fans a 5*5 *1cm running 5000 RPM, complete in a flexible tube so that it can get cool fresh air from outside the case.
Conclusion: The EVO Cyclone without modification is not qualified to cool the FB-DIMMS down.
 

[Pappa]

The silly question I have is the fan blowing Down onto the cooling fins or UP pulling case air through the fins...

So looking at the pictures you have posted you have what looks like a dead space for air movement in the area of the RAM. What I think I would do is install one of the fans that covers a "blade slot" in the back of the case to exhaust from that area and insure that the RAM Fan is pulling outside air (forcing down onto to the cooling fins). Then you are creating specific airflow for just the RAM.

Then you are creating specific airflow for just the RAM.

The fan in the tube is blowing the cool air from outside onto the FB-DIMMs. The fan does not blow on the cooling fins left and right. These cooling fins goes still under the fan along. When the fan blows the air on these fins under it, they cool down, but this has no big effect if the case temp is 40 grd celsius. (Therefore I must the case open now).
Where the airducts are I could not see exactly.
Remember to our first try the EVO shows 41 grd and 4286 RPM on its LED Display. (see above)
Right on the paper-mache tunnel of the RV670 is a big fan, it blows cool air from right through the tunnel to three open blade slots backside.
The case has 2 fans 22cm diameter, each with separate switch and variable RPM regulator.
If I close the case and switch the two fans on, a lot of cool air blows in, but the temperature of the FBDIMMS are going upwards.
See our sample above, to run the machine without special FB-DIMM fan-cooler, temp goes up to 102 grd celsius.
Its very mysterious, but true, the two big fans disturb the inner airflow. I had them always off.

modify: Review from InsideHW GEIL EVO Cyclone Memory Cooler

[Pappa]

The hard part is every case is designed to "look nice" for the user to impress their friends. Other than a few, it was not designed to move air to cool an extremme machine. So it is known that there will be dead spots that air does not move well.
Otherwise we would see a BIG Honking FAN in the Front with a Grill on every machine.
Your drive cage prevents moving air Front to Back which would cool the Chipset, RAM and Hard Drives.

What I would look at is if you have two of the 5.24 bays open in the top to mount a 120mm Fan just push air into the case. If under the plastic front of the case is mounting area for an 80mm fan put one there (poke holes). The idea would be to force as much air as possible. Then fans that exhaust air out of the case will work more effectively.

One might consider mounting another fan at the exhaust of the power supply to help pull more air out of the case.
