Hi Claggy,
I did a general cleaning, heatsinks too, but the inner airflow of the case must be better regulated. I built a airstream cunductor from hard paper and set it in between CPU1 and CPU2 so the hot air from CPU1 goes upwards now and not to CPU2 directly. Some measurement with AIDA64 Extreme Edition will help a bit. Outside it is cool now I can open the window. Roomtemp is 21 grd celsius at the moment.
Looks like my conductor did not help a lot.

It's strange that the core temps on CPU 2 are mostly lower than CPU 1, but CPU 2 has a higher overall temperature, perhaps that heatsink needs new thermal compound, or the sensor is inaccurate.

I found the Northbridge heatsink (40 x 40 x 5mm) make noise and the FB-DIMM heatsinks is too slow and sometimes it hung so both must be replaced in the next days. CPU2 is the right CPU if you look into the case. It seems the sensor or AIDA64 has a problem and reports wrong value.
Or now compound paste, bu I cant believe it....

seems the PSU can do it...
the middle GPU is problematic, not enough(still 2mm) space to get enough air
will see how long it does, before the driver crashes

[_heinz]

it was a short time (1 hour) and driver crashes...
must power off now

[_heinz]

I run the new installer v0.39 on the V8-Xeon, But I can't get any work from seti, pitty.
With stock frequency all 3 GPU's are now running fine.
I set all 8 CPU's under 100% full load with other work.

[_heinz]

Today I got some work from seti GPU and CPU. All are done now. One has  a -9 error, others looks OK, some are waiting to confirm

Last 24 hours I had have 2 driver crashes. On the FB-DIMMS I had have 100 grd Celsius, so I stopped work on any CPU. I need a new FB-DIMM-heatsink, the old is under repair/reclamation.
The GPU temps are GPU1=89 rpm=3360, GPU2=94 rpm=5400, GPU3=91 rpm=3360.
As you can see there is still 2-3mm space between the cards, really small to get enough could air.

Make it look like this. This is how I have my pc. I've tied the bottom of the fan to the chassis and the top to the cpu heatsink.

[_heinz]

Hi sunu,
good idea to set a additional fan before the 3 GTX, but from the right side in the case.
As you can see the door of the case has 2 big fans each with potentiometer to regulate rpm.
Best would be to construct a own heatsink for the FB-DIMMS.
Will see what I can do...

heinz

[sunu]

With 2 CPUs and 3 high performance GPUs it's impossible to keep low temperatures with the case closed unless you watercool all of them. And even with the case open you will still need a fan placed as I've shown you, to force air between the graphics cards. I use a 38mm thick fan for high static pressure in order to push air as hard as possible in whatever cracks are open.

Where are the FB-DIMMS located? I can't locate them clearly from the photo. Are they those things between the CPUs and the top card? Have you tried something like these http://www.computeruniverse.net/products/e90199636/corsair-dominator-airflow-cooling-fan.asp?sr=corsair+dominator+fan  http://www.computeruniverse.net/products/e90322367/corsair-dominator-airflow-fan-triple-kit.asp?sr=corsair+dominator+fan

You could also change some things in your CPUs. What thickness are the fans on the thermalrights? Those thermalrights have high density fins and they perform better with high static pressure fans, that is 38mm fans. Or use dual fans in each thermalright in a push-pull config (this will also help with the following).

Also there is a huge hot spot between the two CPUs. You'll need to get the air moving in the space between the two heatsinks. Move the fan from the left heatsink to the front of it, pushing instead of pulling air.

My P4 2,6GHz machine died, 
I shut it down and now never switched it on.
If I push the "on" switch nothing happened,
maybe to replace the PSU

I could reanimate the old P4 by insert a new PSU and changed the graphic-adapter.
Removed the NVIDIA GeForce 4 4200Ti(NV28) and set in a HIS Radeon HD4670 (H467QS1GHA).
