Introduction: Computer Water Cooling System

Picture of Computer Water Cooling System

Hello. I'm Korean living Korea.

I like looking So many instructables in this site and making my own.

today I like to introduce my Computer Water Cooling System - it's my own design!

It was made at 2008.october

I don't have any confidence in my English so will show you many pictures with lesser word.

Step 1: Radiator

Picture of Radiator


I used Oil Cooling Radiator for car.

I went Hyundai motor shop and bought new but if you want to get cheaper one, can get in an auto junkyard or auto repair shop.

the radiator is aluminium so easy to cut and tap.

and some plastic two touch fitting - to avoid Galvanic corrosion

Step 2: Making Body

Foamex is very good to making something.

Cheap, various thickness, easy to cut, easy to glue

with cyanoacrylate bond, can make very fast

Step 3: Making Body Step 2

Now Look Pictures Carefully please.

I used Some technique but hard to explain all in English.

Sanding Edge 45 degrees makes look good when two plate stick together
and some little across tooth makes two plate are in same plane

Step 4: The Face

Picture of The Face

I don't like easy, simple Instructables anybody can do.

To make special system, I designed face in 3D cad program.

(could more complex design but it means hard to make)

Step 5: The Face Step 2

Picture of The Face Step 2

I prefer polyester putty, but this time there was only epoxy putty.

wet sanding is more better than dry sanding

Step 6: Painting

Painting and lettering.

text is Dry Decal.

Parkoz is biggest Computer community in Korea.

One man in parkoz tuning forum made fan controller board named parkoz controller.

-can control 4 fan speed(auto/manual)
-can display 4 temperature
-compatible several character lcds
-full speed fan when staring
... etc

it's some big and oldie cause made before several years.

Step 7: Test and Fix

Picture of Test and Fix

12V Thermaltake motor was not good. weak and noisy.

Changed cheap(about 4$) aquarium motor. quiet and powerful.

New motor means new water tank.


Motor need 220V so used SSR(solid state relay-non mechanical parts) for switch.

Step 8: Fix Again

Picture of Fix Again

Oh no.....

Parkoz Contoller doesn't work in test suddenly...(crying)

I tried fix it but can't so replace with Parkoz Controller II!!

More little, More Powerful now. :)

Step 9: Installing Jacket

Installing Zalman water jacket.

It's full Aluminium so don't worry about Galvanic Corrosion.

Step 10: End

Picture of End

Finally done.

I thought some LEDs to put in but sooooo tied at that time.

it works good. full load temp is about 45' and about 35' at normal.

forgive my awful english(but I tried). and Thanks for reading ;)

pashiran (author)taratata20152017-02-24

sorry, it was Co-produced by forum members long time ago.
No material was available at the time.

mrmetallica (author)2015-08-24

jeditemple2001 (author)2014-04-11

Your English is better than my Korean.

hansumkrishna (author)2012-07-05

That's called perfection.......and you dont find that in most of the diy of all diy water cooling system i've ever seen......better than the one i made.......btw what are the specs of ur gig.....????

Dr.manic (author)2012-06-21

You did an amazing job and i like the fact that you used lots of photos.Thanks for your contribution.

kostika741 (author)2012-01-20

hi pashiran i really want to know. where can i find a water block ????

greyhuk (author)2011-11-28

Id have to agree. Trust me your English is better than a lot of people. And the case is amazing.

_Scratch_ (author)2011-04-28

Love the front panel, nice 'ible

pashiran (author)2010-01-03

do you mean my own pdf(not-instructables)?

xagop (author)pashiran2011-02-09

yes tnx alot sir.. :-)

abadfart (author)2010-04-06

 very nice you might have already sayd this but what did you use for your coolers

Azurial (author)2010-02-12

just out of curiosity - is Foamex the same as foam board you can find in a craft store?

pashiran (author)Azurial2010-02-12

No, Foam board is very weak. Foamex is more stronger like acylic plate

napoleonis (author)2009-10-04

nice job and design :D

theblindferrengi (author)2009-08-14

What controller did you use? is it posible to make a controller or improvize something?

It's not commercial thing. one man of korean computer community made this.

hmm, interesting. could you perhaps get the circut design schematics for it?

sorry no. I have no data for it

albertfuzion (author)2009-09-03

Great job, your ingenium is complemented with your good taste for design, claps on you

netxpert (author)2009-07-02

brilliant work...

kungza (author)2009-06-16

i don't believe that I meet Parkozen unexpectedly here.

pashiran (author)kungza2009-06-18


L0rd0fferret (author)2009-05-31

Wow i have to say that this is by far the best made instructable so far...extremely well detailed and very innovative. Nice job!

Teenage Skater (author)2009-05-30

Awesome Dude! the craftsman ship is great and it looks honestly professional, keep up the great work!

The_Black_Hole (author)2009-03-01

Dude that's amazing!! you should get a patent on that! i cant believe you made the case yourself i thought it was bought when i first saw it!!! and your English is great man! don't let anyone tell you different. AMAZING INSTRUCTABLE!!!!!!

boazkl0p (author)The_Black_Hole2009-05-23

I totally agree with you: it looks like you bought that case, so neat!!! And your English is fine. Congratulations with this beautiful project :D

pashiran (author)The_Black_Hole2009-03-02

wow. what a praise. thank you very much.

mattameo213 (author)2009-04-09

That is the best water cooling mod I've ever seen (not saying much, but still....) A stereotypical question (please forgive me for asking): But do you play StarCraft?

pashiran (author)mattameo2132009-04-10

I cant understand why you asking about StarCraft. somehow I dont play starcraft. Because... StarCraft is most Popular game in korea. almost my friend played it. but at then i was in army. All Korean men have duty of national defense for 2 years so when i was diacharged, all my friends is good player but i am bad player. I cant play like them in multi, so i quit :(

ddjj123 (author)2009-02-22

good looking and great project but hard to DIY for normal guy without E.T.knowledge

abadfart (author)2009-02-05

thanks I have been looking for a way to make one. I cant afford the kits.

rimar2000 (author)2009-01-23

Pashiran, I don't speak English, too. I am argentinian. Your work is very good, but I wonder if it's worth it. My computer is quite noisy, but I think is too much work to do everything you have done. Is it hot the weather in Korea? Perhaps that is the justification. Or maybe I am too lazy ... ;)

abadfart (author)rimar20002009-02-05

or they run it for a long time

pashiran (author)rimar20002009-01-23

it's worth it for me. Cause I am happy when making something. Was long time to make cooling system and last I'm very tired with that after working 10 hours everyday. But yes, I'm now happy now and don't regret So if you are think making something is hard and lazy, will be easier earn some money and buy Full-made system. and, Korean temperature in summer is about 25-35 degrees.

collard41 (author)2009-01-23

its nice to see some people learning our language, we're so ungrateful aren't we, making them learn ours and not even bothering to learn theirs.

pashiran (author)collard412009-01-23

All Koreans think Korean is the best language in the world.(seriously) But in real world, like recent world-wide interchange makes us learning English. So many students hate English ;)

abadfart (author)pashiran2009-02-05

lol ya my English isn't so good and i live in the US so are you using this for gaming?

Muscelz (author)2009-01-31

GREAT WORK! ide trust that more that ANY bought liquid cooling system, solid water blocks, heavy duty radiator out of a motorbike or sumthing so it can be thrashed around without being cracked etc, piping looks think BUT ide advise on using diffrent 90o bends and joiners, i would never trust plastic inside of a computer, maybe brass joiners and bends? and stainless steel hose clamps? you must be doing some serious overclocking on the 478, what are you running? and what temp dus it sit at under full load and what speed is it overclocked to? GREAT WORK MAN! unbeleivable work, no one would really relise how much time and effort it would take to do that, thats crazy but awsum :)

cyc4015 (author)2009-01-24

Wow, I thought this was an Instructable on how to install a kit at first, that is really professional looking!

pashiran (author)2009-01-23

Thank you. good advice for water. but i don't know where to buy isopropyl alcohol or ethylene glycol here...

uncle_al_0 (author)2009-01-23

That is one of the most professional DIY jobs I have ever seen. You've got quite the set of skills there. Good job that's all I have to say.

Bongmaster (author)2009-01-23

great make there :)

PKM (author)2009-01-23

Hi pashiran, Your english is fine. There's one or two mistakes but it's easy to understand what you mean. Some lazy people who speak english write worse instructions than you :) I like the way you built the case, especially the front panel- it looks very professional. If all you need is foamex and putty maybe I'll do a case like it :)

pashiran (author)PKM2009-01-23

Thank you. :) Foamex is my favorite stuff when making something. all you need is foamex, knife(to cut foamex), ciano acrylate glue(like loctite), and measuring stick. it's all. if you don't insert arc part, don't need putty
