Cooling D.I.Y Cylindrical Water Block

all the 12 picture I've built 3 cylindrical water block and 2 hdd water block
cost for material copper - us$ 20.00
Allu - us$ 20.00
fitting - us$ 20.00
Rad - us$ 20.00
hose - us$ 20.00
pump - us$ 10.00
misc - Us$ not finish yet
about the water block , i'll tell u later how i built them and their pic


this is my setup


pump-->rad-->cpu----->Gfx...........................................................
.........................----->n/b................----> Res
.........................----->hdd1
.........................----->hdd2

i,m using 3/4" od tubing for pump, rad, and cpu. after that i used 8mm od 5mm id using transparent PE hose
i've done flowrate testing for the setup above except rad, and i've got 15% flowrate from my 2500 l/h pump

for the water block, it is moderate resistance with diamond pin matrix inside it to create turbulance and increase it's surface. i've like to recieve some comment and suggestion about it.

 

Sounds cool, and I can't wait to see it! I'm interested in this homemade block idea, because I'm building a few of my own very shortly.

By the way, perhaps you should move your rad to the end of your loop? I suppose it's not that important, but going directly from pump to rad seems like a great way to restrict your flow before you put it to the cpu, and most times pumps don't add enough heat to do justice there. Maybe it would be better right before the res, after all of your loop is completed?

 

yeahhh,maybe tomorrow i'll post the pic.
with proper equipment ,it'll cost you no more than 2 hour for each water block to complete

step 1, lathe the top base(copper)
step 2, lathe the bottom base(copper)
step 3, grind bottom base to create diamond pin matrix(using cut-off wheel and surface grinding machine)
step 4, tapped the necessary hole for push-on fitting
step 5, welding using 0.6 mm silver foil with copper
step 6, surface grinding at the bottom base of the block
step 7, polish using buffing wheel

then, you're done.

 

hmm cylindrical, with pins, and spliting the flow after CPU. ... Sounds interesting. Like a crsos between bladerunner's CPU block (the 5 port one) and a #rotor

 

Remember the flow will be the same all through the loop. If you restrict the flow after the block it will slow flow through the block. That given the order of the parts is to get the coolest water doing the cooling. hence the pump-rad-block-res logic.

 

good reminder, risky. thanks! I tend to forget that the whole system will back up to the worst bottleneck to obtain equilibrium. I can remember it in regards to heat, but when it comes to pressure...

 

help, help me

How can i attach picture picture
arrrrgh

 

Don't attach, LanFe@r, link to it...not nice to use bit-tech bandwidth. Throw it up on a webspace somewhere and then link to it using the "insert image" button above where you write your post.

 

All the picture(12 all)
i've send 12 picture
take a look yourself and give me some comment

 

very nice design! I would like to see how you built it, though!!! Give some instructions...I'm interested!

 

Excellent design - surprised I dont see more of them. Only downside is need for a beefier pump due to turbulence.

 

It is perfectly OK to insert images in your post, as long as they are images that you hosted yourself. Just make sure they don't exceed 800x600 in size.
