The last waterblock is majestic

I wonder how the heatpipe wb performes?
The heatpipe should spread the heat pretty efficiently.

I had some similar scetches of a DP 102 Limited Edition submerged in a cylindrical tank with angeled barbs to create a circular flow. But someone beat me to the auction and a since I couldn't find another one in Sweden a new one w/ shipping cost more than I felt like investing in the project.

[TerraMex]

imo.
you'll have two problems with a heatpipe waterblock.
first, you're adding another layer to the heat transfer,
second, there's optimal temperature points to heatpipe operations.
managing both is not as easy as making a plastic tube around it.


edit:
what i mean is that a heatpipe depends on larger temp differences,
means is that if you cool it too well, it wont be as efficient, as temp differences between
the base and the fins will be reduced considerably.
well, at least that my take on heatpipes.

edit 2:

remember this?

Yeah, heatpipe not performing well under those circumstances was one of the reasons why I didn't want to invest much in the idéa. The heatpipe on the DP 102 is most probably designed to work under a much larger temp delta.

But if you build a heatpipe specifically for the temp delta between cpu and water it should at leas perform better than silver?

Maybe not... but at least it would look nice!

The only use I could ever come up with for heatpipes in water cooling systems was as a transporter and spreader of heat from small and/or inconvenient locations (VRMs; northbridges; inside PSUs maybe?) to external super low flow resistance blocks.

Otherwise the best case scenario would be that the heatpipe portion of your cooler presented 0 thermal resistance right? If that's the case then why have it in the way? And if it's resistance is more than 0, then why have it in the way compared to directly wcing the part? Perhaps if the heat spreading or suitability for running water to it are your primary limitations (see the examples I used above).

My idéa was that the heatpipe could spread the heat to a larger area and increase the contact surface so the wb could be less restrictive but still perform well. I find heatpipes kinda fascinating, mini phase change in a pipe. I guess that's the main reason why I wanted to build something with them.

But you're right, it would just mean more losses.

Btw. I saw someone using a heatpipe the way you described to cool a inconveniently located NB. I belive it was in some norwegian forum, can't find it now.

mmm, that would be an excellent solution for a silent rig, actually. Heatpipe the lot, have a low flow pump + large external radiator, you could attain near silence easily enough.

[Long Haired Git]

The whole point of heat pipes is heat relocation and increase in the surface area where heat is moved to the air.
What point then water cooling?

pH has a good point: fiddly bits can then be serviced when perhaps previously they could not, but other than that?

And for all the hassle, simply putting a heatsink on the condensor of the heatpipe stuck out in the airflow of the case may well cool it well enough.

[Brians256]

Or just heatpipe the heat to the sides of the case and have no moving parts. Success is removing complication. Zalman's idea is great. Too bad they want $3k.

This thing is just scary. The base design has potential but the top is a disaster. From the painted aluminum to the completely ridiculous mounting system.

I am not to sure what to think about this. The only pro I can think of is easily routing hose to an external radiator. This eliminates the need for precision bent hard tubing. However I don't see how this would be any better than a regular water block. Maybe all the extra surface area is for low flow quiet systems.

Would be interesting to see how well it works. Looks more like a bling product though than performance.

Interesting review there TerraMex. Note the thin radiators outperforming the thick ones by a small margin at 12V and by a large margin at 5V. Seems consistent with old discussions.

[fameless]

if i'm not mistaken, the cooltek extream rad in the technic3d.com review is the same rad swiftech uses in their kit, no?

[TerraMex]

seems so. will check later.
visually they do, as the tanks look the same.
(ordered me a swiftech rad )
(hopefully be here by the weekend).

[fameless]

it's a nice rad. nexus fans work very well with it. i just got some panaflo l1's. can't wait to finish my case mod to see how well they work.

[ricecrispi]

They are the same rad.

chinese clone or same manufacturer. We know all how china loves to export.

[TerraMex]

we shall see.
will measure the darn thing and see what comes out of it.

ps: lets not jump to conclusions

[TerraMex]

no, not the rad. still waiting.

Glad to see Swiftech go back to its plan; commercial (wide scale) target market. I wonder if it really fits in a 1U case.
