new swiftech block?

[AngryAlpaca]

MCP600 pump to utilize an increased head loss in the wb - making finally a more balanced kit design (the goal)

I was sort of wondering about that, but then I realized that 20" was the drop, and I wouldn't go for the MCP 600 to combat only 20". Revolutionary may be a bit extreme, but I just suggested it to someone on EOCF... First time I've ever suggested a non-TEC Swiftech block.

That said, I agree that the geometry of a block can improve turbulence, with everything else constant, but keep in mind that turbulence do not cause higher velocity, but the it's the other way around.

in other words....

sorry just could not resist....

so to sum it all up....
Turbulence is a result of high velocity....
high velocity is a result of forcing a lot of slow moving stuff through a small hole...
a small hole is a result of the design.
design got cut&pasted from Pro cooling forums... as per usual....

what I'm saying is.... area and velocity is not the goals, it should not be the goals... those are the tell tale side effects of a good design aimed at increased turbulence. turbulent flow is what you want.... the rest will be there by definition of the science involved.

well, if the flow will be restricted inevitably by the block design anyway...

and as far as I can tell, the design calls for the flow to be restricted right at the center inlet.

my take on it is that barb size in this block can only make a difference in convenience

or I am completely off base

[AngryAlpaca]

It sounds like someone thinks that jet impingement show be used. Small barbs slow the flow, but increase, guess what? That's right: the velocity, and thus the turbulence, and thus it reduces the boundary layer.

Edit: I just looked up impingement, and without the word jet preceding it, it's sort of really stupid.

you like using those words a lot don't you?

hehe, I guess I just don't like those words

don't answer that

They are technical terms! Not buzzwords! Technical terms shouldn't annoy you!

Housing:

The copper housing is stamped, and brazed to the waterblock base.
The surface is treated with protective coating to minimize surface discoloration over time.
3/8" inlet and outlet tubes are soldered to the housing.
Each assembly is pressure tested to 25 psi (1.7 bars)

Base:

The base is a one piece copper forging made of C110 copper, featuring 281 thin pins.

Well done Swiftech. Will like to see pH test this.

ever since they came from cathar's mouth--er, keyboard, they became buzzwords IMO

they don't seem very technical to me...

are they technical terms limited to the just waterblock design, or the entire field of thermal management/thermodynamics/you know, science

...

...ok, fine, I give in

/edit
oh, and I just realized that most of this potentially decent thread was ruined....by me

I'm sorry, I know I especially hate reading through a thread where over a page is worth skipping over

lol
arn't you the same guy who sent pH 4 wbs ?
with 2 more promised ?
I think pHaestus is dead in the water for months

hell, by then I could have a REALLY good product

Ok this is a pin block you don’t need to increase the velocity of the fluid at the start by reducing the flow. Instead the users goal should be flow. Once the fluid has entered the block it is immediately met by pins that will cause the “jet impingement” and increase the velocity. At the same turbulence is created as the fluid moves thorough the maze of pins. I think a lot of this falls into procooling 101 (although I have not attended that class yet).

snowwie... fear not! your cool....

oh and by the way it aint fair to blame Cathar for the turbulence buzzword.... I'm the guilty one there...

[AngryAlpaca]

Yeah, reducing the boundary layer right over the die is a bad thing.

suggest completion of said course at earliest opportunity

I have 40 yr old textbooks using these all these words, and more; and they were not new even then

well then I'm a dumbass

why couldn't you say that earlier?

[AngryAlpaca]

It's irrelevant... And yes, yes you are. (J/k, of course)

is Sunday PM more clear now ?

true but making it a buzzword in computer overclocking geekdom.... how many would even know of such textbooks...

actually I guess the first to mention it here in context with block designing was AL666 pointing to a article on overclockers.com

New block is looking good Bill. Nice lower-flow performance - well balanced for a pump like the MCP600 and "lesser" pumps that many people still use.

I especially like the straight-barbs. Much cheaper and easier to implement, and given the use of hose-clamps, perfectly safe. Have been playing with such myself for the next block, but I'm glad that Swiftech has taken the lead here.

Very well priced. Going to shake up a few manufacturers, that's for sure. Aside from the slightly higher performing White-Water variants which will be able to justify their slightly higher cost, it will introduce a new low-cost benchmark at the budget-middle end of the marketplace.

Well positioned. Good stuff.

[snowwie]

#rotor, my original point is kinda about how everyone in the watercooling community knows who cathar is, but how many know who you are?

[AngryAlpaca]

I'm totally in the dark about the Sunday PM comment. I don't get out much, if you can't tell. I'm pretty sure a lot of people know about #rotor. If they don't, they should. How large would you estimate the WCing market in NA is? What portion of that is enthusiasts?

well I know who #rotor is, and I know who Cathar is;
snowwie, why should we be concerned about who YOU know (of) ?
very small jk

sorry, no mktg info from me
Sunday PM, just folks with time on their hands

no no no .... Cathar is who he is through Dedicated hard work and determination.... combined with a superior understanding of the science involved. He is an inventor, one of only a couple that I know of....

I'm just a guy who slapped two peaces of aluminum on top of one another, with a gasket in between and called it a waterblock.The only reason I did that was because I could not buy a big enough heatsink at the time as there wasn't anything big enough back then.

I don't know who I am. Lack of sleep does that to you.
