Assistance with external cooling project.

[Hansfragger]

Hello everyone. I have begun building an external water cooling setup. So far I have purchased a HW Labs Black ice 2 extreme radiator, Angel eye acrylic reservoir, 2-Enermax 120MM fans, 1/2" ID tubing and various other fittings. Right now I am stuck trying to figure out what the approximate total volume of cooling fluid will be. As this is my first stab at WC'ing, I am going to play it safe by using one of the non-conductive fluids(Fluid-XP or InertX). I have been searching for months now for any formulas or charts to measure how much fluid per foot in 1/2" ID tubing, how much in the rad, etc. With the outrageous cost ($35 USD per 32 oz), and probably another 10 to 15 USD for shipping per bottle I would like to come as close as possible. At this stage of the project I am using approximately 10'. Finding a forum with so many experienced, and extremely intelligent enthusiasts is pretty exciting! When I first decided to begin this project I thought my studies of hydrodynamics and thermal transfer at the US Naval Propulsion Engineering school would be enough, but a quick perusal through this forum showed me how in-depth and advanced the PC watercooling scene has developed. The extremely thorough and technical reviews and comments tend to keep one very humble. Once I finalize the last design details I will post this as a work in progress with photos along the way. I want to thank any of you in advance for your help and I appreciate your time. Have a great one!

Fill the system with distilled water and measure how much you put in. Voila.

US spent millions developing a pressurized pen that wuld write on anything

russians used a pencil

keep it simple?

[Hansfragger]

Heh, Heh. Nothing like a little humor to brighten up the day! Thanks. That was going to be my last resort. Cool story.

Well, you could always do some extremely complicated math involving volume of a cylinder and other shapes and sizes...but yeah I'd say keep it simple.

Nah, thats why the US is a Super power still and Russia is no more. The US strives to do it BETTER (having the money to do it is a bonus). Ink is not erasable. However, in this case the point stands. You should always wash the system out before you do the final fill anyway. Manufacturing residues, dust and whatever else can be inside the rad.

I agree. If your gonna spend that kind of dough, than I would do the same. Fill the system with distilled water and see how much it takes. Make sure you get enough for spillage and testing. No need for mathematical equations. A rough guestimation is still good. It's always good to buy more than not enough.....simple.

[Hansfragger]

Thanks for the feedback. Rinsing the rad out sounds like solid advice. You can't beat experience!

I filled 1 foot of 1/2" tubing. It took approximately 1 1/2 ounces. Later I will fill my Black Ice Extreme 2 and Angel Eye reservoir then post the results in case anyone would like to know.

(pi*d^2*L)/4 , but yea the easiest way would be to fill with distilled water and measure it out.

pi*r^2*L is shorter

Where else can you find so many neurons firing in one place!?!?!?!?!?!?!?!?

[Hansfragger]

FYI:

1/2" ID tubing - 1 1/2 ounces
HW Labs Black Ice Extreme 2 - 9 ounces
Angel Eye acrylic reservoir - 8 ounces at working level, 10 ounces to the top.
( Rad and reservoir were measured with no fittings)

Sorry, but that's not what happened.
Paul Fisher developed the "space pen" on his own (with his, not gov't funds) and donated several pens to the Apollo missions (previous Mercury and Gemini missions had indeed used pencils) recouping his development money in additional sales (big "space" fad on at the time).
IMHO, the major advantage his pen had wasn't the pressurized cartridge (I think this dates all the way back to Biro - Hungarian? inventor of the ball-point pen) but on using solid ink that was liquefied by the "shear" of the textured ball rotating against it.
I'm pretty sure the pens were used on Russian space missions as well - although they probably had to buy theirs - and they might have put the cartridges into Russian-made bodies (complete with "CCCP" emblems) as they were having a space fad at the same time - and competitive feelings ran pretty high.

Now, if you were to compare the radio in a F14 to the radio in a pre-Sukhoi MIG there's be a completely different story in complexity (AFAIK, Russians were late to move from tubes - although I would guess that some of that was simply due to tubes' resistance to EMP - they almost certainly were way behind the US in hardened ICs).

Should've read this earlier. Easiest would have been to just put the loop together and weigh it empty and filled with water. Density of water is close enough to 1 g/cm^3 for our purposes.
