Help required! Custom Universal GPU Block Design

post #1 of 3
Thread Starter 
Hi guys,

I'm currently in planning stage of my new project to build a 100% passively cooled system using the Zalman TNN-500AF

Currently the GPU block is rather puny, made entirely out of aluminium and maximum cooling capacity is 75w via 3 heat pipes.

I would like to have a much beefier version of this with minimum 6 heat pipes, capable of cooling a 150w + GPU.

My 3d modelling skills are none existent and my Photoshop skills just as bad smile.gif

I've been in touch with Marc @ Liquid Extasy and he has said he would be interested in taking up this job, so before I take it further would like to get a better grasp of things.

This is the original Zalman HeatPipe Block (click to enlarge)



I wish to create a block with minimum 6 holes for heatpipes, pref 8. Heat pipes are 6mm in diameter, and assume holes in the block are too (but will double check)

This is how it is layed out in case, and how it works.



I would like to use for example the EK-VGA Supremacy as a base for my new block, perhaps with a widening at the top so can get more heat pipes holes in there. This is a rough Photoshop of my vision (please don't laugh)



Please could anyone more experienced in the field offer a helping hand with a better design or suggestions to mine, and perhaps a better mock up than my poor Photoshop attempt. The above images were sent to Marc @ Liquid Extasy and he kind of understands my vision, but since he speaks no English it's a little difficult to grasp if we're on the same page. So if I can offer a clearer vision / mock up it would help greatly)

many thanks

You need to resize your images, they're tiny.

I'm curious whether a 10 year old design has enough cooling capacity for modern components.

I've included links below the images, but will edit to remove thumbnails for full size

Cooling capacity is more than enough. According to Zalman specs, each side panel (2 of them) can handle 200w cooling capacity each.

You have to remember these were designed to cool 90nm 100W CPU's, so modern 22nm Intel stuff is a breeze. I plan to use a low power i7 Haswell 45w CPU, which leaves me around 150w cooling for the GPU. That's only on one side, the other side is practically free, usually just cools the PSU.

Another example would be motherboard, older ones the Northbridge would need to be cooled as well as VRMs, modern day boards heat sinks are pretty much for decoration so thats another source of heat pretty much removed from case. Original 10 year old PSU, inefficient would also generate a lot of heat, replaced with a platinum psu which produces significantly less heat.

Generally modern stuff in way more efficient and produces less heat, apart from GPU's since they have become much more powerful than from 10 years ago, hence why the cooling is inadequate.
