DIY waterblock questions

post #1 of 11
Thread Starter 
i have not watercooled before and i'm considering it because my current air cooler is not adequate. i have access to a machine shop so milling etc would not be a problem for making my own block. my main question is what is the downside of an aluminum block? i have read that there are galvanic corrosion issues if you mix metals, is this impossible to avoid? are there other issues or should i be ok if i have aluminum rad, block, and barbs? thanks in advance

Aluminum will not get you the kind of temps that copper will. I Don't see the point in making your own block if it's going to require a lot of work and work worse than a good store bought block. Also, the companies that make these blocks spend millions of dollars developing a good thermal design and micro fin structure and I'm doubtful you can just draw something up without requiring a lot of work, time and money to end up with a worthwhile design.

EDIT: As for corrosion, most barbs are nickel plated so no worries there. Radiators, well most good radiators have brass tubing with copper fins so the tubing isn't actually copper. In the end though, you'll still get sub par performance unless you can use copper/silver/gold as your material and you can come up with an even better thermal flow than what's currently available on the market

Something like this would be very difficult to machine. A GPU block, on the other hand, could be reverse engineered pretty easily. If you have access to CNC mills and some scrap metal, you could make your GPU blocks. This is more doable.

Uh...that gpu block isn't more doable at all, that picture is just the outside of the block. The INSIDE where the water goes through also has micro fins just like the cpu block. They're both very difficult to make and the gpu block is even more difficult if you want a full cover block and not just a gpu only block.

another thing i'm not sure on is size of the block. most i've seen are about as small as possible. if you had a larger block with water running throughout, what would be the downside?

I've been wondering about how feasible a large CPU block would be. GPU blocks are amazing at cooling the processor due to their size. A large CPU block should net similar results. Problem with a CPU block is it would be nearly the same problem as a full cover GPU block. It would need to be so custom, that it would only work on one motherboard. The design would need to be pretty radical if you were to keep the mosfet cooling stock as well.

there is a pretty good size area available especially if you go upwards with it instead of outwards

This guy made a CPU block. It even has microfins made with a dremel!

I doubt its easy, but it can be done. Probably not worth the effort unless you want to do it just for fun. thumb.gif

yeah, i've been looking over several diy blocks. im probably going to go with a simple labyrinth design with 4 turns. but like i was saying, it would be easy to stack several of these together
