Hello.

I'm planning to do a copper water cooled HD casing system for my 2
drives (IBM/Hitachi 180GXP and 7K250). I've come up with 2 designs both
using 0 curves just one copper pipe going through (touching) the copper
housing. I'm planning to make another, bigger housing in which i'll put
this copper one. I'll put some sound absorbing material in the larger one,
than I'll mount the housing on the bottom of the computer.

Here are the ASCII art designs:
Code:
DESIGN #1

2PPPPPPP1        P                   
ccccccccc     ccccccc     ccc2ccc     
cDDDDDD c     cDDDDDc     c  P  c     
cDDDDDD c     cDDDDDc     c  P  c     
c       c     c     c     c  P  c     
cDDDDDD c     cDDDDDc     c  P  c     
cDDDDDD c     cDDDDDc     c  P  c     
ccccccccc     ccccccc     ccc1ccc     
side view    back view    top view     

DESIGN #2
                                ccc2ccc
2PPPPPPPPPPPPP1        P        c  P  c
ccccccccccccccc     ccccccc     c  P  c
cDDDDDD DDDDDDc     cDDDDDc     c  P  c
cDDDDDD DDDDDDc     cDDDDDc     c  P  c
ccccccccccccccc     ccccccc     ccc1ccc
   side view       back view    top view

Legend:
c = copper
D = HD
P = pipe
1 = pipe in
2 = pipe out


I think the design #2 is a bit better since there is twice the length of pipe
going through twice the amount of copper as in #1.

OK, now i'm wondering if this even works? Both drives are touching the
copper housing at their sides but there is only one pipe going through the
top. Will the cooling effect even spread to the sides? Will the temps be
reasonable?

Another question conserns the other housing (packed with sound-
absorbing things). In my design there is 0 air comming in or out. Is it safe
to run my HDs without a hint of air? The reason I'm asking is because
there is this hole on top of the HDs with a warning "Don't close this hole"
written besides it. So is it safe to have it air-proof tight?

Thank you for all the answers...

Oh yes,

I won't close the two holes, there will still be a bit of space in the
copper housing (on top).

Cheers

Welcome to SPCR, TheJFK!

interesting ascii art, surprisingly yours is very clear and easy to read.

you have the tube going straight, that's interesting - how are you going to get the water coming back towards the source? i.e. you have water flowing from '1' -> '2', eventually the water will have to come back in the general direction of '1', yes?

i think your design suffers from the fact that it's too unrestrictive. water will simply pass through and may not be sufficient enough to significantly effect the hard drives.

i think a cheaper and more effective design would be to have 2 copper slabs either side of the hdd, with copper tubing running up one side, coming around the back of the hdd in as gentle an arc as possible, and then coming back down the other side.

Hello.

And thank you, nice to be welcomed ;)...

OK, I was thinking about making the whole thing like this:
Code:
-------------------------
I                I      I
I   CPU          I      I
I   p p          I      I
I   p p          I      I
I GPU p          I      I
I   X p          -------I
I     p           pppRRRI
I   PPPppDDDDDDDppp  RRRI
I   PPP  DDDDDDD     RRRI
I   PPP  DDDDDDD     RRRI
-------------------------
Computer casing (from side)

Legend:
R = Radiator + shroud + fan (drawing air over the rad)
p = pipe
D = HDD casing
P = Pump
GPU, CPU = blocks for both
X = straight line back to radiator


Yes, it only has one in and out water plug on the HDD case, a straight line
tube that goes into the pump. Do you think that wouldn't be sufficient
enough (not enough restriction)?

As you can see, I'm aiming for simplicity and clean design. Yes, I'm
aware of the "two tubes at each side" design of a HDD case. I am giving
that design a thought too, but I'dd have to put the HDs into the upper
slots, where the CD drives reside. Was just thinking about doing
something different... Anyhow I'm using a bit of that design here too,
because the HDs would be on the copper boards touching the copper at
their sides (they would be screwed to the side). Plus I was thinking that
the heat goes up, so to keep the water flowing on the the top copper area
would help disperse some of that kind of heat (plus, hopefully, would
spread a cooling effect to the side too...).

Thanks for a prompt reply.

not to sound mean or anything, but i don't think it would be worth your trouble, especially with the hard drives in that position in the case. they would be cooled by the airflow from the radiator, which is sufficient to keep the hard drives cool.

if it doesn't inconvenience you too much to make it, then i'd say go ahead and make it. theory and speculation can only be so accurate :)

Hmm....

Guess there was a misunderstanding. I'm building this watter cooled
copper housing to put it into a bigger (non copper) "box" stuffed with
sound proof materials. There would be no air whatsoever going into the
box (or sound going out). I'm just going for the complete silence of the
HDDs. Since there is no airflow they would easily overheat (hence the
water).

Cheers

ahh ic sorry my misunderstanding.

in that case you have a very good reason for cooling your hdd's.

how are you going to get air through the radiator?

Heh, sh*t happens.

It will be pulling the air in the housing (not blowing on the fins).

Here's the ASCII :):
Code:
   sRRR
  FsRRR
<-FsRRR
  FsRRR
   sRRR

Legend:
R = Radiator
s = Shroud
F = Fan


I heard that's the best way to do it (better than blowing on the radiator).

Cheers

so this would create airflow, which will end up inside the case?

Nope,

I have a 80mm blowing air out placed below PSU (Chieftec case), plus I
have a 92mm on the bottom of the PSU (Enermax - 2 fans). Both
undervoltaged.

yep so you have those 2 fans exhausting air out of the case, and the fan on the radiator pulling air into the case - thus you have airflow in the case going from front to back.

if you place your hard drives in this path of airflow (like you have in your 2nd ascii art post then that will provide sufficient airflow over the hard drives to cool them.

True,

but kind of hard to get it into a path of airflow since I'll have them closed
in an AIR PROOF BOX. Again, I'm not going for the cooling effect (I
know I can have that without a water cooling thing) but for the silencing
one (I'll close them in a box where no air could get to them).

Check this link out: click
It's an article on silentpcreview. Notice the last pic on page 1 where he
puts the water cooled HD into a plastic box and than the first pic on page
3 of the finished product. That is the same to what I'll do (but don't think
I'll use plastic for the outer housing).

So what I was originaly asking was the design of a copper HD water
block, that I'll put in a housing (similar to Ron's on the above page).

Hope that clears all the misunderstandings in this post.

hi, im prettymuch doing the same as you but im gonna make something like this
http://forums.procooling.com/vbb/showth ... hlight=hdd
i have the stuff all cut up it just needs joining togeather, mine will be for 1 drive each and ill be making 2, theyll be put in cases that fit in the big drive bays with sound proofing material in them, theyll be running in parallel. hopefully when its done in a couple of days i can get some pics of them
