alrighty, i have quite the problem on my hands here, the company i work for has hired a company (out of professional courtesy i wont say who) that, despite there numerous alleged "degrees" in engineering, cant seem to create a working liquid chiller for our systems... i guess i'll start with what there trying to accomplish.

an average system is running an overclocked AMD Athlon FX-51 and an overclocked N-Vidia 5950 Ultra on either an SK8N, K8V, SK8V, P4C800, or P4C800-E motherboard, in a custom LianLi chassis. and now quietly taking those extreme temperatures from both CPU and GPU (primarily the ram chips on the GPU of course) to an incredibly low temperature is there job.

-now with there cooling solution:

ok lets start with the radiator, (i'm sorry dimensions arent really my thing), its about 70mm long, and is 120mm wide as it is in height, with a 120 mm fan running at 2300rpm to "cool" it, and this unit is stationed right at the rear of the case. now there are a total of 4 tec's (running at about 74 watts per tech thus not really cooling anything) all of which are on the radiator itself with 4 waterblocks stationed ontop of them. the gpu has a "thermal transfer" plate with a cooling block mounted on top (on both sides of the gpu) and the cpu simply has a waterblock mounted. thermal transfer on the gpu is achieved by thermal pads.. and thermal tranfer for the cpu is achieved by arctic silver 5. now in the front of the case we have dual 120mm fans running at 2300 rpm and... well.. that just about does it, oh and instead of running water,, there running a glycol/water mix.

now, i may not have a "degree" in engineering, let alone a little peice of paper saying i know what i'm talking about... but bloody hell this things a disaster. these guys think they have it all figured out and refuse to change anything and after our last meeting, and 2 straight hours running a quieter air cooled system beside there liquid cooled (air cooled ran about 20 degrees cooler on the cpu), they've decided to drill a hold in the top of the case for yet another chiller of yet the same crappy design to "hopefully" get the temperatures they desire..

what i see is wrong is for one the tec's, there for one cooling the liquid itself then running to the GPU and CPU instead of tec's running directly on the GPU/CPU then to disperse the heat, via, the radiator. also the tec's are running on too low a voltage.

now heres where it gets interesting, my boss is totally down with these clowns despite him being unsatisfied with the temperatures, even though they have ACTUALLY said that "in NO WAY can there system be improved WITHOUT modding our case"... now say if you were given one of these chiller systems and ripped it apart, how would you mod it to make it work (general temperatures were seeing are about 70C for the CPU and near 90C for the GPU. and just to recap, ripping one of these systems apart will give you the following:
-4 tec's
-a 70mm x 120mm x 120mm radiator
-a 120mm fan
-4 tec waterblocks about 40mm x 40mm x 15mm
-1 CPU waterblock about 60mm x 60mm x 25mm
-2 GPU waterblocks....the top is about 35mm x 20mm x 15mm
the processor side is about 40mm x 40mm x 15mm
-as much thermal grease as you need
-as much tubing as you need

i'll get as much additional information if anyone requires it.. and i'll check back here soon.. thank you soo much for your help.
