unconventional design
 

hi,
I've drawn a model for a cpu water block. It will be solid copper cube and channels will be drilled through. Its a rather simple work since there is only drilling process and the idea is to use it as a heatsink cooled by water. I'll apreciate any ideas. below is a render (original wont have curved channels as this model shows)

Re: unconventional design
 

it looks quite difficult to make from where i stand (4 drillings in top and baseplate), multiple drillings in side planes.

it doesn't look like it would cool well too. if i were you i'd go for a rotor style block

first link is made by my mate puzzdre, second is an article i did for madshrimps.

they are good performers and quite easy to machine with limited resources and equipment.

That's a really nice drawing... but I'm with glamour on this one. You'd have a hell of a time machining that waterblock. However, if you wanna give it a try, by all means go ahead. I'll be happy to help you out in what way I can. Then please tell us how well it performs. Good luck!

Re: unconventional design
 

thanks for the comments,
I thought that it would be easy since I'll drill just straight holes then seal the proper ones from outside. I want to contain the heat inside the heatsink rather than dissipating it with fins and the water travelling inside will absorb it. Surely I have no idea how contain and absorb idea will work and how hard the production will be but I'll give it a try and we will see :)

hmm without wanting to go into a too lengthy discussion, the wb will absorb the heat from the cpu anyway, its just how fast you can transfer that heat to the water.

but by all means, feel free to experiment

Re: unconventional design
 

The bend in the middle isn't necessary.

You should take a look at Lytron's flat plate coolers: similar design.

Re: unconventional design
 

As one of lecturers once said, unconventional is a by word for expensive, low performance pains in the ass.

I'm sad to say i think that the block falls into this catagory.

Re: unconventional design
 

here is another one,
this is the simplest design I could think of; 2mm thick copper plate bent to fit a plexi glass in the middle and fins at both sides. plexi will be the part to route water from side to side and create some turbulence with some grooves and bumps inside.

by the way I wanna now how you test your blocks before putting it over your cpu. I don't wanna burn my processor while trying these custom blocks.. how can we simulate a cpu with small resistances, how many watts do they produce (athlon xp), any ideas for a test setup?

Re: unconventional design
 

There's little work being done in adding air sinks to a water block; I'm guessing because it's hardly worth it (which seems reasonable).

I'd hold on to that design for a GPU block.

To test, as long as your block design is roughly better than a Danger Den Maze 1 or 2, you'll be ok, but make sure that it's mounted to make good contact.

If you want to get into some serious testing, that's a whole different ball game...
