Planning Graphic fullcover - Size on the fins/channels

Hi

Is looking at some of the newer fullcover, like the EK GTX680:



Any that know how big the fins over the GPU Core is + space between ? (Depht, thickness and space between)

Regards Henrik

(Its planning to my build

 

Still searcing

 

Unless some one's prepared to dismantle a block to take the measurements the easiest way to find out is to contact EK. They've always responded pretty quickly to my queries.

 

They dont really give details away around there block - Have tried ...

 

IMHO exact size doesn't really matter. if You want to make own FC block better take look at own tools and equipment. what size of fins could You produce? fins typically 0.8-1.2 mm thick, same for spacing, 3-5 mm height. most vendors have to find compromise between cost of production and performance. and due to that fin's size is more about cost than performance

 

Looking at mills do to the work, and is thinking about something lik 2mm thick and 4mm in height - Could get a 1mm mill but think is will be a lot more work (Time) and the changes of it breaking ...

 

for 2 mm thick fins think about diamond structure like on mcw60

 

Yeah, but is thinking that the flow will be worse, but more surface to transfer the heat .... Vill look at the different block on the marked, maybe some older ones ...

 

Found a 2mm mill at work, that can cut 4mm down - Maybe it could make a decent result

 

o m g , im looking all over the net for a CAD template of a 680 , the back part that makes contact with the ram , gpu and vrm and the holes for some capacitors that are on the way

i dont want to buy a block just to get some measurements ... do u guys think a company could give me their templates ?

 

Well company usually don't let own designs away. Take caliper and measure down all you need.

seems to be to find a good balance between increasing surface area of copper without killing flow...

 

Got this 2mm, but is looking at some smalles ones
