Key Features:
High Rated Intel CPU NVIDIA Graphics Scratch Build Water-cooled
System Specs:
  • Intel C2D E6600@3.42GHz /ADATA@2GB_360MHz /ASUS Commando / Home made WC with ZALMAN CNP9500 /Sparkle 7950GT@512mb
Performed Mods:
Home+hand made watercooler with ZALMAN CNP9500 /2x80mm LED fan /RAM fan(Pentium 3 HSF) /a bit cable mangement
I've cut out the heat pipe from CNP9500 near the base of the copper base. Rebending and reshpaing 6 copper pipes into curves to match the orginal size and shape of CNP9500. Aluminuim car oil radiator 400x185x20(LxWxH). Industry used high presure air compressor tube. LG fridge ice box containor used for water tank(4Litres). CAR raditator coolant and lots of soldiering, its pretty hard to soldier the copper pipes together because one is soldier but then the others melts. I used a water feature pump which produces 1000LPM@20w useing 240V

Superb idea very nicely put into practice. 9 from me.
Would be interesting to see what temps you are getting from it.

Thanks for the conment.

It redue the temperature by 20*C : oc'ed 380x9=3420
idle=37*C
load=50*C
BEFORE the moding using ZLAMAN 9500: oc'ed 380x9=3420
idle=48~52*C
load=68*C

ALL the temp is at a room temperature of 30*C

I gave you a 9 as well. That's an impressive amount of custom work you did there. Good job. Just imagine how low you could get the temps if you mounted a couple of fans to the oil cooler.

I am not sure but the raditator not that warm maybe 3~7*C higher than the room temp.
I have 5 80mm fan but I am not going to install any more fan because its good enough for me, I like quiet ^_^

Hmm.. so they dont have wicks O_O. Yeah it would be better if water blocks had an intergrated heatsink.

Does anyone have a water cooling system. I want to compare with thier's WC system to see what are the difference.

That's some nice work, I also like your use of that old P3 fan for the memory chips. If after all that modding and you have no leaks I give you a 10,

very nice modding there. im sure a lot of thought and effort has been put in to it. i gave you a 9 too :) however, the temps you are getting could be bettered by high quality *normal* watercooling.
then again, you would have to spend a bomb for any better, so well done!

Thank you for the comments. You guys must not forget the result are compared use the orginial ZALMAN CNP9500 not the intel stock cooler.

I do not think this is a bad peformance due to the following reason:

1-The room temperature is at 30*C and my idle is at 37*C, that is only +7*C. Now I can't can get any closer than that because there is just no way I can get lower than room temp, room temp is what cools down the raditator.

2-I overclocked to 3.42GHz@vcore on auto and in BIOS 1.488v

3-The humidity is very high at 81%

4-Which Water cooling system are you compare with at what temperature,humidity and how much it overclock.

There is nothing inside the copper pipe from the CNP9500, so many people just doesn't believe in me. I been there and I have done it" THERE IS NOTHING INSIDE" Those people who think there is fluide or gas inside will.... they just can't take it that they are wrong, its as simple as that I am afriad.

LOL :P don't you just love my P3 cpu fan used as ram fan.

my AMD X2 5200+ watercooled runs @ around 18-20'c idle and upto a max of 35'c at full load.

It is overclocked from 2.6Ghz to 3Ghz @ 1.45v though.

Beautiful work man, I am very impressed and I knew you could do it with the Zalman. Well done. Just for the hard work, I give you a 10/10. Ingenius for the use of the p3 cooler for the ram. I love it.

Nice Setup

That is a pretty wild setup. I've always wondered how hard it would be to customize your own Water System. Nicely Done. You can check my water system out if you like. It is listed in the case mods. http://www.techpowerup.com/gallery/667

Nice Work. 10/10 for the labor alone!

Thanks guys.
And yes its hard work, it took my father and me 1 month to think, plan, buying the right material and do it in scales. And it took us(father+me) another 1 week to solder the pipes to gether and the most easy part is installing the whole thing into and onto my computer case only one day. The water tank is pretty tight in my case but lucky I have 4x 5 inch bay. The water tank took up 3 bays>.<

Your spelling/description is a bit iffy, but the pics explain most of it. 9/10, i wish you'd made it a little clearer what youve done.

Looks better now that you've added more pics of your setup.

Just one further question, did you remove the wick from the tubes before attaching the additional copper tubing?

Yeah, if he had a Zalman VF900, he could do something similar, although there are only 2 pipes to work with.

Yes, I still would be able to mod VF900 using the same thing that I did do my CNP7500.

Join one side with copper tubing and the other side I need to cut enough copper fin so it will have enough room for the tubing.

Yes but I don't have any of those coolers, all I have is CNP9500 LED but still I can apply what I have done on this onto other coolers.

I am going put some green LED on my side window,drill 6 holes in the front cover and on the base. I am also changin my LED fan into either Yellow,white or green LED. Some cable management with the circular tubing thingy (dont know how to say it).

All will be done after my goods are carried to Australia when my relative comes for holiday. ^_^

Oh yea I also replace my water tank with a tank that has TEC placed onto it. Its now nice and quiet.

Dude you rock!!
This is a mod I was planning myself I am unimpressed by the cooling radiator on my liquid cooling system and was going to add a similar mod for a second radiator.

I want to talk about WHY there's no fluid in the heat pipe when you took it apart. I've read descriptions on heat pipes before and they say there's liquid inside.but then no ones taken one apart like you have.So whats the point of heat pipe. to move hot air back and forth.

Will this is my theroy.
1. Copper is a very good conductor.
2. The heat has to be spread out through out the cooler.
3. Using a huge solid tube would cost too much.
4. So How to solve this probelm. Use thinner tubing.
5. But wait its still to expenive. Thats make it wholo inside.
6. OK now cost down but the consumer wont buy it.
7. We have to make a special feature out of the heat pipe.
8. Thats say."Inside the heat pipe there is liquird or gas in side."
AND PEOPLE LIKE ME would say "WTF its common sence, pressured gas to make it liqiud ? wtf no way to dangures. Liquid ? what liquid I dont see an. poision gas that I open it would become CARBON or H2O.............. I dont think so I dont think any posion labeling on the package.


SO yea that is what I think happed.

I'm starting not to like heatpipes, everyone I touch is super hot, built 6 or 7 systems with a heatpipe theme, going to stay away from the lie, so my new build will be a Foxconn N68S7AA nForce 680i SLI, going to put it in a Silverstone BJ07 Black case, just waiting for my new camera and some other parts, going to make my first worklog with this setup.

I thought this was explained somewhere on TPU... I guess not though.

What I've read about how it works: Water will boil at a lower temperature when put in a vacuum. Since Zalman, or any other company for that matter, cannot use special supercooling liquids for cost's sake (and for safety regulations), they must resort to using plain old distilled water to serve as the active ingredient in heatpipes. They put a small amount of water into the tubes and then vacuum seal it, reducing the water's boiling point. From there it's common knowledge; the heat from the CPU causes the water in the vacuum sealed tube to vaporize into gas and rise to where the fins are, taking heat with it. After the heat is released, the water then proceeds to condense and travel down the tube where it will repeat the cycle for as long as there is enough heat to vaporize the vacuum sealed water. The reason why you don't (or didn't) see anything when the heatpipes were opened was because the very, very small amount of water that was in the tubes either a) evaporated into the surrounding air or b) diffused into the air to the point where you wouldn't notice anything there.

Either way, very cool mod and a very clean setup. It would be awesome if you could polish the copper tubing up a bit but I guess you can't have it all :laugh:

i have been there also. and i believe you.lol

I worked my ass of to solder a few extra heatpipes on my previeus motherboard..
Asus m2n32 sli-deluxe
its in my old gallery..
just visit my new gallery first and there is a link to my old


But i cut the old heatpipes open and changed them with thicker ones.

And yes, there is NO fluid or gasses in them...

its works by moving hot air back and forwards...

vote for me too. i dont know how to make a link..
but just search for firefly's
the you will find it i think..
