Water cooled DDR :)

[froudeg]

I've had a lot of interest in the water blocks i made for my ram that can be seen in my avatar.

They are made from bars of aluminium, i drilled a simple channel down them, epoxied off the one end, then cross drilled the 2 holes, fitted in a small bit of brass tube for the hose connection, epoxied and thats about it.

On the ram modules themselves i used normal thermal paste, and used hot melt glue to hold it on the ram module - if i ever need to change the ram i can just carefully peel the glue off.

Some pics:






More pics of them (and the rest of my work in progress system) can be seen here :

if you have any copper in the loop, you already made trouble!!!

[froudeg]

Not with inertx - atm its water, but im building a chiller using a litre of inertx preflurocarbon coolant

holy ,your my hero

[EmineM]

nice, one quick question... how did you get your NB so clean... no matter what I do the stick guey stuff on my Abit ic7 g NB wont come off.

Goo-gone

[Unseen]

incredible.... I want two of those for sure!

Let's see some temps bro, maybe this'll catch on like wildfire

[froudeg]

Temps.....

Well i run the ram at 3.5 volts, without the water blocks the modules heatspreaders (which i of course removed) get scorching hot when gaming/prime95...with them, the blocks themselves are only 1c above ambient.

Hard to tell what the ram module temps are themselves, but if i stop the water flow and play a game/run prime95, they soon warm up and become scorching hot - so they are definately doing their job lol

[slavik]

check the water temp in vs the water temp out ... that'll give you some idea

[bh2k]

You have one of the coolest systems I've ever seen.

[tylerhskate]

Thats crazy, you should start selling

[boshi]

why do you run them like 1 in the figure, rather than like 2 in the figure? 2 would use less tubing.

[Lithan]

2 would be more restrictive due to tighter bends.

[froudeg]

Yep, 2 would be impossible to do the tight bends - without having to have great lengths of tubing to reduce the radius of the bend.

froudeg nice setup! What chanel diameter?

[deadmanwalking]

i have been trying 2 build ram water blocks for quite a while and i keep running into trouble

is it possible 2 get the design of your water block off you so i can overcome some technicalitys

[nicholarse]

what size barbs/tubing is that?

[froudeg]

Here's a pic of the channels i drill in the block (ive drawn on it in black):



As you can see its fairly simple, just a straight channel down, then 2 channels for the brass pipe inserts - to connect the tubing to. I used a very long drill bit to do the job, was bit fiddly as i had to empty the swarf out all the time - but it did the job.

All i did then was seal off the hole i drilled on the side, with epoxy...and also epoxy in the brass pipe bits.

These blocks r tailored to my motherboard btw - they are quite thick and will only work if there is a good bit of space btwn the 2 dimms you intend to use them on. Luckily with the ic7-g there is plenty of space. If there is less space you could always use a thinner block of aluminium - but your channel diameter may have to be very small. - altho that problem could be alleviated by a more elaborate design using 2 channels in and out in parallel.

The tubing size is just 5mm internal, 8mm external - its small but very flexible and nice to route round the case. I wouldnt put this inline with a cpu cooling loop etc as its too restrictive - but i've used a seperate pump to cool this section...you could always use a splitter with a good pump.

It doesnt need much water flow to keep the blocks at room temp

[masterofpuppets]

COOOOL! I'm gonna try this one day when I get off my ass.

[Mod_Evil Br]

This very roox, what you fiz your conections on your DIY block

[deadmanwalking]

how have you managed to get the ram inside of the block??

If you pay attention to 1st pic, you see that he've two blocks to cool one ddr module

The blocks are 'attached' to ddr module with transparent glue by glue gun I think.


Btw, nice job froudeg

[froudeg]

Thx lasac

Yep, they are held on via hot glue....and i used oridinary thermal paste (white goop) btwn the chips and the block.

[deadmanwalking]

yer but how did u make the slot for them is wat im asking???
