"Chilled"

[SIP YEK NOD]

The Tools

 

 

The water cooler: Designed to cool 4L of drinking water to 7*C every 1/2 an hour. in a closed system test, i found it to bring the water closer to 4*C.

 

Here it is with the water heating element removed. rewired, and ready to be installed back into it's case.

 

 

 

The hoses and pumps: 1/2" ID outlet split and feeding 2 3/8" ID hoses.

 

 

The set-up and testing:

 

The system was run without waterblocks to test for leaks, the 1/2" hose runs from the pump, through a small hole in the bottom of the resivor(if there was a leak, it would be here) and to the 2 outlets. it ran for 24 hours without a single leak, and got the water down to about 4*C

 

 

 

The waterblocks:

 

CPU: Gold plated copper/anodized aluminum Zalaman ZM-WB3

GPU: Anodized aluminum Zalaman ZM-GWB2

 

installed:

 

 

 

 

The result:

 

 

 

 

Upon start-up after sitting for a few hours, the CPU temps are around 15*C and the GPU temps are around 28-29*C, after running prime 95 overnight with a 900mhz OC(from 1.8 to 2.7) the CPU temp was at a steady 31*C Load, 25*C Idle and the GPU temp was at 40*C load, 35*C Idle with a 50mhz Core OC.(from 350 to 400). the water in the tank remains steady at 15*C. so Overall a drop of about 8*C at the CPU(with an asus star-ice), and a drop of almost 35*C at the GPU.

ghetto-ass

so you just dropped the pump into the water chiller? heh, awesome.

i say get some sort of a heat-exchanger

 

however, zalman makes poo waterblocks.

[sate]

Gah, first Az is customizing his PC, and now you.

 

I feel like doing mine special too now.

 

BTW don't you have a computer with better specs to test your liquid cooling system on? Or wouldn't it be sufficient?

submersible pump no inlet tube. much quieter(although it does add a little heat to the water)

 

as for heat exchanger, with the water in the system being approximately 10*C lower than the room temp, a radiator or such would seem counter-productive. what i need is a metal reservoir to replace the plastic one to better cool the water, the cooler is on the outside of the plastic basin.

i say ditch the reservoir, put in a t-line. as for heat exhanger, a radiator would be useless since its ment for air. what i meant was something like this

its a copper coil.

 

myself, i was once thinking about building something like a 6ft bong cooler

You suck.

 

 

Thats all I have to say.

Don't be hatin', Mr. unoverclockable

[Forfit]

 

I must say SIP, do you hold a record for injecting NOS through your computer and keeping the temperatures at a below freezing level?

[SIP YEK NOD]

no. but i did look at phase change before going with the water thing. the phase change was just too damn expensive. this whole set-up cost me about $130

[anus]

Plain awesome. The temps are looking great atm, if they weren't overclocked they'll be running so damn cool . Great work, Sip.

[Devyl]

That would be awesome on my rig, only thing is (like phase-changing setups) the 7800GT's & GTX's have a "cold bug", letting them not work @ temps under 35C...

[SIP YEK NOD]

that kinda sucks. i am freezing 2 containers of water right now in our freezer, later i will throw those in, and see what kind of temps i can hit

 

 

 

edit: i took the cooler out of the corner there, and saw about a 5*C water temp drop, and 2*C cpu drop

phase change for both cpu and gpu? yeah that'd only cost about $800-1000 per cooling unit (prommy or vapo). Of course if you meant TEC, then its like, $80 per block and you need power for it

[Forfit]

Sip, maybe you can also buy one of those Mini Fridge things that college students have for beer and stuff you know, and put your computer in there...and see how much lower the temps will get, i think it would be cool as long as like nothing freezes. lol

5809 in 3dmark 05

 

I don't know why, but that reports my fsb as 44mhz, its actually 300, but that's not important.

 

CPU:

CPU AMD Athlon 64 2707 MHz(1800MHz stock)

 

Video card:

Core Clock 433 MHz(350 stock, 370 factory OC)

Memory Clock 1128 MHz(1000 stock)

 

 

(could be affected by the graphics card difference, but my cpu score was higher than that of a FX-55 w/ a gigabyte 6800GT as tested by toms hardware)

 

 

 

ps: compy likey Icey

 

 

 

 

@Forfit: daggdave actually suggested that, and i thought about it for a while before seeing the massive ammount of ice formation in my mini fridge. Humidity = bad

 

 

[Majestic]

A mini-fridge is not a very good idea for simple reason - its made for cooling sources that constantly produce heat. food is simply cooled and then kept that way... food doesnt generate heat ;p

 

so to sum it up, the fridge would die/break. actually, now that i think about it - a water chiller isnt a very good idea either... but hey, if it works
