ZERN PQ PLUS new Waterblock

Jag · 10-23-2004, 04:27 AM

Check out this waterblock from a German manufacturer - ZERN.
It managed to go all the way up to nr. 2 in the Watercoolplanet chart.
The work on the channels is very good.
The walls are like 0.2mm thick?

The block is 49x49mm. I count 40 channels in what roughly appears to be a 24mm width, or 0.3mm channels with 0.3mm wall thickness.

Impressive to get that level of fine cutting without damaging the fins.

They didn't use little bits, they used saws. 40 to a shaft I'll bet.

What was that block recently that used two plates that went together to produce micro channels? Looks kind of like that as far as I remember, though I haven't seen a review of either's performance that I can totally trust as yet.

I believe it was a 1A block.

Cutting saws is something that was suggested, when I was designing Radius. Yes, possible.

I've also been pondering lately if there's some kind of cutting wire out there that could do this...

Roscal · 10-23-2004, 02:03 PM

There's nothing difficult here and yes it's cutting saw + CNC. No problem because fins aren't tall (~2mm). But here is a 0.25 mm version with ~8 mm copper fins using cutting saw too from a polish friend and no problems (so little bent) :

Another technic said by BB2K is the wire EDM I used to do minichannels from 0.5 to 0.25 mm too without constraints :

You've got the choice to make such design...

I knew that they were being cut with saws. NeoMoses had attempted such but saw the fins start to flex and get damaged when he went too fine. I did a 0.5mm channeled block with saws, and had similar issues. I think it's more of a case of either of us not having the correct saw blades with the wrong attack angles on the blades for cutting copper.

Cool stuff. Wonder how long it takes to make such a block.

I guess cutting both sides of a fin at once would equalize pressure on it. Did either of you use multiple saws?

Apart from laser, straight, tensioned cutters could be finest of all. *Ponders kitchen egg slicer* Toothed blades narrower than wire?

#2.....No f'n way!!!! Hell their #6 is overclockers #1, if that is the case then they have some serious blocks that definately need to be looked at by Phaes!!!!

It must be said that 0.4C separates #2-#6, and on a testbed where they only do a single mount, that's still well within normal mounting variations right there. i.e. in a single mount scenario, #2 to #6 are statistically inseparable.

Additionally their testbed flow rates are typically within the 0.25-0.5gpm range, and blocks do behave quite differently down at that level.

In any event, both the NexXxoS XP (the #1 block at that site) and the NexXxoS HP Pro (the #4 block) are on their way to Phaestus, and should be with him as soon as Canadian customs clears the delivery.

Is there a US distributer?

It's not just a question of difficulty, but of implementing such design without scrapping a lot of blocks, and they seem to have done it (and to top it all, it's the excellent price of ~35€ or 44.37 dollars).

Well let's see how long they stay in business.

somebody on the forums said they only test with the Eheim 1048
