At exactly 6' of head IIRC, so in an actual loop it would probably be lower. Its a beastly pump though.

It had struck me before how flexible you can be with this system. You are cooling a large area of uniform heat so you have a lot of options.

You could even have 2 or more completely separate cooling loops running through the same water block where the water never actually meets (by using some sort of divider).
I considered doing this



and probably will, but I'dlike to figure out a way to make the inlet be centered instead of on the sides. Plan is to make something very similar to the sketch I made that muffy linked to and then make various mid-plates to test real world what effects I get. Starting out with a simple water-cooled block wih a single mid-plate...one inlet/outlet, then step it up to two inlet/outlet, then add mid-plate sections that will have the two inlet/outlet be competely seperate loops from each other (bottem loop being very restrictive because of high fin count and very thin, which hopefully will allow it to transfer heat sufficiently to the next mid-plate up...which will be very free flowing). If that works out ok, will build upwords with more mid-plates to make a block big enough to take a 62mm tec on all four side. Or fall back to the simpler design of not having seperate loops in one block and build that upwords for the TEC.

My plan of an optional direct contact TEC waterblock for the CPU is not dead yet. Except now it will be direct contact to the cpu and a waterchiller...within the cpu TEC block as well, that can run without the TEC on......just imagine the pic above with more sections and 4 TEC's around it and then 4 blocks for each TEC. All I need now is for all our planes to stop breakng so that the shop where the mill I am using is at is not so busy.

Hay Man that Block is just ridiculous !

There's so many stages to it that wont realistically do anything but restrict the flow.. By the way like you said it's crucial to have the the water hitting the centre of the block . I don't know how you haven't managed that with 3 stages to the cover ? HEH keep up the good work

Here's my simplified version of your block

NOW it's not meant to perform well cos it's to un restrictive and needs the other barb for proper flow distribution but but you get the idea ..

Well that definitely tells us that the more even the flow is over the entire surface of the block the better the cooling as a whole.

The early ones used thicker fins and it performed ok, wasn't till they started doing micro fins that it really started being a top performer. Take a look at the internals of HK, Swiftech, EK and many other commercial blocks. I really think you'd be better off making numerous thin fins instead thicker ones with hole notches. And also add a mid plate to the block to help more evenly distribute the inlet/outlet flow or mill a thick top plate to achieve the same thing. I'd sketch a pic of it, but at work on a work computer. I'd bet with a proper mid plate to defuse and distribute the inlet/outlet or a thick top plate milled to do the same thing, you can get the difference between your highs and lows to be far closer then what it is now. But I am really just an armchair quarterback here.

O yeah the HK designs have been a round for ages and is very affective.

i dont need a mid plate to even the flow out IF thats the aim. With 4 barbs you can do this very effectively.my next post will have much better flow distribution, though not perfect as im just taking a guess at it AND my main it not = flow but = temps . it's all good fun though. I could mill thinner channels but to do that id need to uses a slitting saw which at this stage i dont want to.

i guess for me i don't want something that's gonna take forever to make and cost lots in weight and materials. Which is one of my main aims.

By the way Herc130 i assume your CNCing your block ?
