yeah...but for 2days non stop without a single leak and somemore the wb is sealed with silicone and same with the pump also..
now i have to fabricate a bracket for my am2...

wah lao @_@

1800L/H? would it effectively absorb the heat? even my 1500L/H nirox is overkill in 2 WB loop.. seems like waterfall on my reservoir when i fire it up , not to mention my WB gives pretty big restriction... (Whitewater)

dude..i dunno about that...

but i read some info from overclockers.com

http://www.overclockers.com/articles1088/


cnp here..


Myths about Water and Flow
Myth: Water must slow down to fully absorb heat.

Reality: In a closed loop, a given water molecule actually spends the same amount of time in the radiator, no matter how fast it is moving, as long as the water is indeed moving.

If this is a difficult concept to understand, think about a race car on a track. If the track is one mile (5280 ft) long and the car is driving at 60 mph, the car will spend about one second in a 100 ft stretch. Think of the 100 ft stretch as the radiator.

If the speed is doubled, the car only spends ½ a second in the 100 ft section, but it passes through that same section twice a minute, so it spends a total of one second in the 100 ft section per minute.

errr i dun really understand this also..but triple read it..seems logically enough

the concept is simple, just think it as the energy to be transfer in that period of time thats all.......

basically, water has limted heat transfer coefficient, so faster flow may be better if u always having a steady supply of cold water. But the radiator has limited heat dissipation rate too rite. So in a close system, faster flow limted the time for the heat to be absorp and dissipate, so it ends up does not perform better. U make a simple energy balance calculation then u will get the concept.

i'm interested in looking at ur custome block, i was thinking of making my own too

That's the total balance that one have to achieve with the WC set chosen .....

trade off ..... the way of setting up and performance of each component have to be taking into account....

thats what i thought too, IMHO, the flow rate doesnt affect the water block too much, but it affects the heat dissipation on the rad. The longer the water stays in the rad, the better it is being cooled off before beginning a new cycle. The bad part of having very high pressure, chances of leakage are higher than lower pressure pumps, and sometimes you can hear the water flowing sound as well...

The main thing to balance IMHO would be the amount of water block in your setup, the resistance of your entire loop, and the size/quality of the rad which will affect the temps.

Correction here

1. Flow rate affects delta values of certain water block design. Usually of pre-Apogee designs. This is because water evacuation influences the heat soak at plate itself

2. Flow rate however does not affect radiator efficiency. What affects it is these:
i. Number of passes
ii. "Bar and fin design" or "tube and fin design"
iii. Material of construction
iv. Restrictiveness of end tanks
v. Air flow restriction of radiator
vi. Bar rows in radiator

3. High pressure is not of a worry to consider because if you did your homework well and sealed up tightly hoses at barb points, you should not be worrying stuff like that. If it was, pumps like those from Iwaki wouldn't be of recommendation for big loops

However I do agree with your last paragraph of statement as balance is a key issue. No point in having a 3*120mm BIX radiator when all you're doing is cooling a processor. Nor does a Delta 25mm*120mm tri-blade fan going to be of help if you use a low air restriction radiator either

A damned good guide which I keep referring to is this:

thx for the correction.

Im rather new to WC, just finished my complete loop yesterday.

My journey started with TT Bigwater 735, from there on changed the rad to the 120mm ones (got it extremely cheap, RM60).

From there on.. got a 2nd hand water block from a forumer here (AquaExtreme Whitewater), and made my very own nirox pump with moderno's help.

My setup back then was Nirox > Whitewater > TT 2x120mm Rad with 1/2barbs > reservoir > pump. Well... i wasnt satisfied with the performance, performance wise, its not that bad, but on par with high end air cooling, just minus the noise.

And now.. at last the ghetto setup is gone

Current setup

Nirox P3800 > Cooltrek DP1202 > Apogee GT > MCW 60-R > MCRES Micro > Nirox P3800.

Pretty much satisfied with it at the moment, able to cool down my rig @ overclocked speed with only 800RPM. Total silent setup

what do the oldtimer here think about my setup below?
1st time ever got heart to try watercooling even though heard about it for the last 10years(yes im old)
maybe scared also..Im abit clumsy..

Got a old oil cooler from BMW with a good design.Quite big..clean the old oil thru..
the pump aqua zonic 1800l/h
waterblock design got from various site in the net with some mod done to it.2 layer with copper block and nylon bar as top layer not arcylic
would be using T-Joint for the moment b4 made a reservoir or buy.


Ill upload a picture if anyone request it..
and do correct me hard ..as im newbie in wc stuff.

Oil cooler.. O.o

hehhe yeah........bought it to use in my car last time..
but retired play car liao.....the thing nvr use for 2years liao...
but will change to heatercore soon also..

from my readings, oil cooler could work pretty well too
im really curious of your setup, mind to post a pic and some performance screenshots?

car oil cooler i think , need a very powerful pump....

not really since heatercores/cooling cores are generally not so restrictive. What makes it supposedly restrictive is how the inlet and outlet is oriented. Otherwise it's no worse then a Black Ice Xtreme. This is because since oil has a lower viscosity then water especially after factoring sludge build up, less restriction is quite critical

Sure..I will post it up some picture of the cooler and whole setup.
For performance wise...still waiting for time to make the bracket to fit my am2 mobo...
once everything ready I will post up the temp screenie.

the oil cooler is a diff kind of design.Its not the same design as those u saw before..
Ill post up the picture soon..

nice nice... ive seen a BMW Bike oil cooler before though, would be awesome if its something like that

Here is the diy wb that i did..
hehehhee not soo impressive though

sory about the pic quality.






There would be some revision of it soon.
Would make some more hole on the mid section part.

Any advice?


Here is cooler picture...
No good camera phone...

nice... but i think there can be a lot of improvements on the waterblock

here some result for my rojak system heheh..

Idle.




Load temp is around 50C.Duh! Better about 10c than my old hsf same spec and vcore..BUT Im quite satisfied for the cost n setup option.Upgrade option is very wide.
I believe a good result can be a achieve from better aftermarket wb or better design diy block and also radiator.
Soon will try heatercore from car.

not to shabby..I guess

after relocate the radiator position.manage to shave another 7c from load....
heheh now that is better hehehe
