One catch to you design though, you are going to have very large head losses through the block itself. Without knowing much about the pump itself, I'd caution you realize that you are going to get much, much lower flow than the rating on the pump.
I'd also have to agree with Tec about milling it thinner above the core. Doing so will limit the cross sectional area through which the heat can flow away from the center of the block and in my opinion would cripple the use of the outer area of the block. For now I would personally just shoot for a constant baseplate thickness.
maybe this will work better then deper in the midel and going up to the site's (see pic.)
going to use a 5000l/h (1200g/h) pump so that wood be planty even if i just get 25% of that do to dreag of all those small channels
have bin talking to the site a bout this but was thinking its also usefule to the rest of you so copied it to here
When I saw you first design, I immediately wondered why you chose an "end-to-end" flow approach as opposed to a "center- outward" design like most of the mainstream blocks use nowadays. Of course, it would be hard to not use an end-to-end flow with your fin design. From my tinkering with different blocks, the biggest revelation for me has been the fact that regardless of the block geometry, if you have a decent pump and radiator, just about any block works well. Certainly better than most air cooling solutions.
As to base thickness, I believe with an end-to-end design like yours, start with something on the order of 1/4" (6mm) or so. Like the last fellow who replied to your thread, you can always mill it down further. I personally like your idea of thinner right above the CPU. Keep in mind that the best performing water block I have tested to date, had a thickness of only .050" (1.25mm) but that was a spiraling center-outward design.
There is beginning to be a split in water block design, whether informed people want to acknowledge it or not. There are water blocks that excell at cooling straight CPUs without the use of a peltier device and blocks that perform ever so slightly less with a straight CPU, but do better with a peltier device. End-to-end designs like yours seem to fall into the second category. Thin base spiral blocks tend to fall into the first category. That is my gut feeling and my gut rarely lets me down.
Yeah I have bin thinking of a spiral block to but haven’t find any solution to the surface aria problem, whit what I am look at till now, haven seen one yet
Only in those new all copper heat sinks use the same approach to the problem thinner fin’s and more surface aria
The problem I see whit those spiral block’s is that even do they do a real good job you still have a dead aria where the water come’s in at the back of the channel and I don’t have that problem whit mine design
And I am going to use a real powerful pump 5000l/h (1200g/h) little overkill I no but what the hack got it for free
and whit those little channels I going to have a lot of turbulence in them so they will cool even better (that’s anyway the theory behind it but what the heck have seen some wild stupid one’s here so how am I to think mine is any better
All whit all think that whit the huge surface aria this will work even better only to bad I cant compare it whit other design’s it wood be very interesting to see
And if I ever wane put a peltier on it that will also work perfect
So I hope I have the best of both
