sunu:
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.

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...

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


--- End quote ---
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).
