Question what’s a more efficient cooling block

[michael westen]

Hi I have a question

I have bin looking a round for water cool block’s and the only thing I see is maze block’s isn’t it mouths better to cool true a small gap whit the size of ore tube you are using, across the hole white of the aria that you wane cool look’s like 90 % of the water is doing noting whit a maze

and a other question isn’t a option to cool the perlier strait whit the water instead of first cooling the copper and then thats is cooling perlier I understand you have more change on leaking but isn’t this more efficient ????
Ore are there also other problems????

Greetings Michael

Damn Dude, Im getting totally behind on Watercooling..
I Dont even know how it works..

Fill me in how..

I'd like to purchase myself a Watercooling system in the future..

Or possibly now if i know the mechanics into it.

But for the 2-3 Weeks, Im gonna get my self a good ol' Delta for 13 dollar's plus shipping..

Delta

7000 RPM

Bit noisy.. Put's out as much air as a 120mm fan ..

Replace all ur 120mm fans with Deltas..

Nobody have work on this ore have any experience whit this
Just seen one diggrr has given me the link but I don’t think I like this option

Really wood like some feedback on this before I am going to build this thing

Well, I'm not the watercooling guy but I will see if I can help a little. The reason for the maze affair is to let the water contact maximum surface area of the block. If you use the straight design, The contact area is limited. Another thing is to introduce turbulence in the water stream. Leaving your hole or channel rough surfaced will do this. If you are using a larger block then utilize the inside surface area to its maximum. Look around on the overclockers site for some pics and info. You will get some more responses after Christmas I am sure.:beer:

Hello Michael,

To start from the cpu's surface...The copper cold plate spreads the heat from a (roughly) 10mm x 20mm surface of the core to a surface of 48mm x 48 mm, or 2,304 square millimeters, the size of a peltier.
The heat then moves from the top of a peltier (the same 2,304 square mm) distributing the heat to the water's surface, where in a maze block (guessing here) with over 6,000 square milimeters of surface area being cooled by the passing water.
By spreading the heat to such a large area touching the water, a copper waterblock by far makes up for the inefficient transfer of heat from the extra mating surfaces.

I know that direct cooling would probably work, but it could not match the surface area of the copper and water that the copper block offers.

Any other questions?

Hey Michael, here is another link to a professionally made direct peltier cooling waterblock. (aluminum)
www.leufkentechnologies.com/watercooling.shtml
Scroll down...at the bottom of the right hand column. He has a flat $19 US shipping fee for international orders. $24 for full kits.

I don't know if anyone here has tried this unit, I have not.

Hey diggrr yeah see were you are getting at but

You still have to move the heat from the perlier to the copper the 2,304 square mm and I no that copper is better then water to transport it but my feeling is still saying that a narrow gap over the hole surface does the job better because you have a greater flow over the surface plus if you keep the gap narrow but whit the size of the hoses you are using you get a other benefit that will help I think water move’s faster in the middle then on the site of tube (see picture)

Um, which delta are you talking about. The 80mm delta screamer puts out 68cfm, that's about the same as a low flowing 120mm, and it's MUCH more noisy. I high flow 120mm puts out well over 100cfm and is still quieter than a delta.
Personally I'm going for replace all fans with water cooling and have a big rad fan - I run a 172mm fan that can push up to 235cfm (at 54dBA :p), I have it throttled so it's quiet.

Acually delta's made a 80cfm 80mm screamer

Here's the link that I've really been trying hard to find. They are using your principles of keeping water velocity high, yet direct cooling the pelt's surface.

If I had a cnc or even a mill, this is what I would build for direct cooling a pelt. (the one nearest the bottom)

Note the damage to the peltier was caused intentionally by them during the testing of the adhesive. They ran the pelt without pumping water, and without a heatload on the cold side. They litterally tore the pelt apart taking it off the waterblock.

This I believe is the most efficient design that you were looking for, and it uses minimal copper stock also.
And use a peltier with the edge sealed against moisture, it will make a big differencein how long it lasts.

Have a good day...John

so more surface area for the water to touch is good, and more spirals or channels gives more surface area. So would a block with a large number of small channels would be the better design?
