Production Aquanaut Basic/Extreme - Ultra Low Profile CPU Block & Pump Mount Combo

[samyope]

All of them can if you rewire the molex power to the 4-pin power. I don't know of any that has a 4-pin only by design though.
Only thing you have to make sure is that whatever you plug it to can take the load but you are fine with your controller.
2A fan headers on motherboards can take a 12V, 1.5A ddc pump no problem.

From my experience it is best to leave the molex, for testing and filling the loop. You may not want to power up the whole system when the loop is not filled and/or not working. With molex you can power the pump with ATX power jumper without powering up the motherboard. You can use a potentiometer to adjust pump speed when filling/testing.

I agree, however for less cable clutter I still cut out the molex. I use a Noctua NA-FC1 to do what your describing when filing my loops. Great bit of kit.

I missed this by a week. Any idea when this will be available for general ordering?

Maybe this will be obvious when assembling, but I can't picture how the pump attaches... the screws that fasten the MCP35X top to the pump are definitely intended for the POM/Delrin material that Swiftech uses, but I can't imagine it's suitable for cutting its own threads into the Acetal block?

Hmm, ok, looking more closely at the prototype images, I see that threads are already tapped in the top part of the block. Are we responsible for sourcing appropriate machine screws? I only see the counter-sunk screws for the cold plate. ?

If you have any specs to share (i.e. threading), that would be amazing!

Are there any DDC pumps that can be powered through the 4-pin connector only? Wouldn't mind getting rid of that molex and plugging into my aquacomputer, which can handle the maximum loads

EKWB DDC 3.1 can do it. It has only 6w power and it able to push a loop with two radiator and two waterblocks. However it's a little hard to find it lol. I found it from the second-hand market.

I have a 3-pin to molex adapter for that purpose but you are right, it is convenient to keep the molex for filling the loop.

Just FYI, the person asking about that was using the Aquacomputer controller (the Quadro, I presume). It works without powering the whole system on.
Once the PSU is jump-started (so the Quadro is powered via Molex), any pumps connected to the quadro ports that are pre-configured to be turned on will work. I used this method for bleeding my custom loop with the Alpacool DC-LT pump (by connecting it directly to the Quadro and jumping the PSU).

I think it is standard 20mm M4 screws that you get with any ddc housing, Swiftech uses shitty self tapping screws.

All pumps that you buy should include the M4 screws already. Different pumps may have slightly different height due to its housing (and different screw lengths). So it is not practical for me to provide screws for pumps.

Thanks, that's totally fair!

In case anyone else is planning on using the MCP35X, heed @samyope's comment—it won't come with the appropriate hardware. The body looks to be about 20mm thick, but the head of the screw may actually seat significantly below the surface.

All in all, this makes me want to pick up a proper heatsink… the Swiftech one is oddly-sized, and also attaches with self-tapping screws. ?

I have bought a switftech, I can confirm the screws they use is not M4.... I have bought about 5 different DDC brands, and it is the only odd one out...so buyer beware

I grabbed a cheap Barrow ddc housing that should do it. I will try to tap the Apogee drive to M4 to get rid of the original screws. Disassembly is always a pain with the self tapping screws, I always fear that the little supports will break with the torque.

Don't think you need to tap to M4, you don't need the top, which is where the threads are. You just need to get some M4 screws with similar length to those of original pump. No need to "break" anything.

Oh yeah I know, it is M4 threaded which is great and standard
I tapped my Apogee Drive 2 top to M4 because there were no threads and I broke one of the protusion on the top where you screw the stock housing with the self-tapping screws.
Had to glue the bit that broke with loctite, @August appears to have one too, so I was just describing what I did in case he wants to use his pump with an aftermarket housing, while waiting for your block.

I haven't looked at Swiftech too closely maybe will do that when get back to office tmr. Swiftech "DDC" seems "slightly different" from others. Hope apart from the screws, the rest will be ok.

Just realized that Swiftech MCP50X (the one I got) is not compatible with standard DDC pump tops. But MCP35X seems to be ok.

 

[samyope]

The MCP35X is supposed to be a standard DDC. The MCP50X you got pictured here does not look like a DDC at all.

Double checked MCP50X, physically it fits into Aquanaut water block. But more testing is needed

 

[fabio]

Maybe the new EKWB VTX is similar to the MCP50X? I really loved the VTX, but is thicker of 1cm than the DDC. But support all the DDC top!

Any photos of the VTS pump (internals)?
