Swiftech's new CPU waterblock MCW5000 - Page 4

MadDogMe · 12-01-2002, 04:27 AM

BillA!, how are you holding the Cu tube in the block?, I've been wanting to make my own 'barbs' from Cu/brass tube but am not sure what to fix it in with (when it can't be soldered) Lexan for the most. I thought about getting a die for the tube and a tap for enlarging holes but is there enough thickness on Cu pipe to cut a thread into?. I'm not sure...

So what's the best goop to use?

...

Doh!, is JBweld the best stuff you think?, is there anything better?, is two part epoxy better? (as long as the tube is 'keyed up' enough?)...

BillA · 12-01-2002, 07:28 AM

I use JB Weld 'cause its convenient (and it is 2 part)
I think Ciba Geigy sells their Araldite epoxies retail over there
just be sure it is 'rated' for water and a reasonable temp

yes, abrade the bonding surfaces, and super clean

Bill,

I talked to Bruce at Cooltechnica today and he is sending me the MCW5000. We discussed the Swagelok fittings (which he ordered, but they shipped him the wrong part).

I was wading through Swagelok's catalog and did not identify the fitting you used in your tests. Will you be so kind as to shed some light on the part number?

Thanks in advance

BillA · 12-03-2002, 08:08 PM

Bruce said (sorry to quote you Bruce)
"it seems like the P# of the 1/2"NPTM to 1/2"OD Male Adapter that you have is: 8-TA-1-8"

is that correct ? no idea (the connector has no pn on it)

you're not putting it on the 5000, eh ?

hmale · 12-04-2002, 06:14 AM

Thanks for the reply Bill.

I looked up p# 8-TA-1-8 at Swagelok's site and the interior dimension for this fitting is .37".

I will pick up a pair of these and test for performance Vs the standard fittings provided with the 478-UHT (which I also have).

Once again thank you.

No Problem Bill. But apparently Bruce said it all wrong

.
The correct Swagelok P# is: -8-HC-1-8
for Brass: B-8-HC-1-8
for Stainless Steel: SS-8-HC-1-8

Here's the catalogue:

Hi Bruce,

Did you get my e-mail regarding the order of a front bezel of an AMS case?

BillA · 12-04-2002, 01:31 PM

hmale

you do realize that with a TEC you have a completely different bp heat loading than how I was testing ?

ahh Bruce
that will teach me to quote w/o approval

dacooltech · 12-04-2002, 01:34 PM

Hi Onno,

AMS didn't get back to me on that yet. I'll give them a call right now, and find out what's going on.

dacooltech · 12-04-2002, 01:35 PM

No worries Bill

Halo_Master · 12-04-2002, 01:39 PM

Thanks Bruce,

I am waiting, because i have the money and want to spend a small fortune.

just noticed what you said
you do not need/want a pair
-> just one on the inlet
use copper pipe stuff for the outlet

(ignoring the TEC 'problem', eh)

hmale · 12-04-2002, 01:58 PM

Bruce,

Thanks for the info and all your help...It makes alot more sense to me now.

Bill,

Oops...I do have a UHT, but I also have the UH...seems like I'm collecting more blocks that I can ever use at this point...sigh

I remain respectfully,

hmale (which stands for easily confused)

__________________________________________________
In between cross-word puzzles here at work, I had time to think about your statement Bill.

It is obvious that the heat load impact on a wb's bp is different using a TEC Vs the heat load from a CPU die alone.

Although I was not planning to change the fittings on my UHT, but rather my UH based on your findings (and my curiosity) your question has left me more confused than I normally am.

Does your question imply that increasing the inlet fluid velocity will not increase the efficiency of the water block because of the addition of the TEC? Or am I missing something else here?

Cheers!

BillA · 12-04-2002, 03:50 PM

with the -UH you have a concentrated heat source against the bp, on the opposite of which is the jet; very effective

with the -UHT you have a uniform heat load applied across the entire bp, the jet helps but will not produce the same magnitude of change (as compared to the smaller jet with the -UH)

clear as mud now ?

hmale · 12-04-2002, 03:59 PM

Thanks Bill

You have parted the sea for me...you are my Moses

Cheers!

MadDogMe · 12-05-2002, 04:27 AM

You want the outlet barb to be as large as possible don't you?, to reduce backpressure on the jet?...

crotale · 12-06-2002, 04:26 AM

Is there any test-results on the MCW5000? Or when will they show up?
