temps? that radiator is so F****** HUGE!!!!!! geezus.....
Whats the heat dump of a pump that can force enough flow through such an oversized radiator and still get required flow rates in the blocks?? Thats what your massive rad will be getting rid of.
I dont see how your going to get any better temps than with a pa120x3 or whatever. Doesnt matter if your water temps are always at ambient, if you havnt got good flow rates through your blocks your not going to see up to scratch cooling.
This size rad would be great for about 10 200W pelts.......not for around 200Ws of CPU and GPU....
^^^^
give this man a cookie he thought of the one thing no one else did.
but theres no reason it should be a "brick wall" to flowrates. sure, its huge, so water spends more time there. but it also has friggin 1 inch inlet/outlets, single pass, and probably largish flow tubes. while its utterly useless in a standard WC loop, it's perfect for either multiple computers, a multiprocessor server, or a high-powered TEC system (ie parallel TECs, GPU/SLI TECing, etc)

go and buy the fan for that rad :P
Recently it is quite warm wether here. At night its not much cooler. (South California), so little use of keeping rad outside. I will put it outside though, because nights may be cold (but recently not been cold)

I'm not saying it will be a 'brick wall', but believe me, even with huge bore pipework, its still a MASSIVE resistance to flow compared with a normal radiator.Quote:

Load temps top off at around 36C CPU, 38 GPU1, 37 GPU2, 32 Motherboard. This is with No Fans or any Induced Airflow
I don't know if I mentioned this, but McMaster-Carr has not shipped the 1" to 5/8" Reducer-Coupler needed for attaching the Iwaki. I coudn't wait and proceeded by using a 1" - 1/2" Reducer for the Radiator connectioin and stretched a 1/2" Tube over the Iwaki's 5/8" Intake. This will reduce its flow, but I do not know how much.

I must mention that This Radiator has 67 Tubes in the front around 17" high. It is also Dual Row, meaning it has actually 67 X 2 = 134 Tubes. The MD20RZ has 22 Feet of head, yet the tubes do not burst with power as they have done without the Radiator. When you touch the Radiator, you can feel the water moving. It vibrates. But Flow is reduced a lot more than I expected. If I were to change a few things.. I would have got the 1 Row Version (Civic RX) which is identical, except only one set of Tubes, thus a lot less flow restriction (at the sacrifice of surface area, but its overkill anyway). Just for comparison, Black Ice Pro has 11 Tubes, Xtreme has 22.
If I use the correct fitting, the volume of the tube will be increased 1.9531 =~2 times what is is now. I hope this can increase flow somewhat.
oh you mounted it to the side of your case? thats awesome, and so are those temps :) nice job.
Now im tempted to clean out an old radiator and use that for my setup. Those temperatures are making me drool.:slobber:
Dual Row is actually less restrictive than single row. Xtreme has less restriction than the Pro. I have test data of my own showing this.Quote:

Interesting. I never would have thought that. Assumed twice as thick, twice as much reduction. Thanks for correction:)Quote:

for passive, a thin (1 row) radiator lyin on its side (so that if lookking from above you can see the fin surface and sorta see through it) is optimum. easier for convection to occur this way.
so to answer your question. yes.
After the Winter break. I put a table fan and shrouded it the best i can with towels around the koyo.\
3dmark05 ::
ambient 22c. CPU: 27idle/32load 31idle/31load on gpu1 30/31 Gpu2. 30C chipset.
Cpu went down 5C , with delta of 5C idle/load. Gpus lost 9C, eliminating the delta between idle/load.
Increasing the fan to loud speeds gave no gains. I can conclude that only a small airflow is needed to cool the water back to ambient with its 167 fins.
I'm looking for automobile radiator fan(table fan is ok, but not look neat). As well as ways to make a gigantiC shroud for this.
Maybe AC to 3V Converter so its a undervolted to low RPMS. Or a Pulse Width Modulating controller. I don't know any way besides that to lower a Car's Fan RMPs.
I heard somewhere takes many amps (40) to start up. but can run at 6 or 7. Might be troublesome.
ideas on fans? or how to make shroud?
Thanks
man those temps are great even without a fan, i would flip it like maxx suggested and just stay passive like that.
One thing of notice is the Fins are very sensitive, and I've bent a few inches of them by accident. If I can get a good fan, I can get 32/31/31/30 with ~20dbl.
I Need to shroud this radiator to protech the fins from accidental dammage.
Anyone know as to how to make a Custom Shroud for this. I have dremel tool. Maybe sheet metal?
My goal is to fix the radiator+Shroud/Fan so that it can stand upright by making the bottom flat by maybe gluing it to a sheet metal. Then Place the Case and the Radiator on a Sheet metal leaving 2 inches between them. then the iwaki behind the case screwed into the metal.
Also the problem how how to power a 12V DC Car Fan
Im sure there are shrouds for this radiator in retail. Probably the manufacture of the car that this radiator is supposed to be made for..
Also, with your SLI setup, the GPUs dont read lower than 30C. that is why t he temps seem to have no delta.. The actual core is below 30C at idle.
OO, Nice Maxx. Was wondering why no delta (seemd little too good to be true)
I serached everywhere, and couldnt' find a shroud for not only this specific koyo model for 88 accord.. but for any koyo radiator.. koyo seems to only make the radiator. Possibly the original shroud for the radiator the koyo replaces fits on the koyo itself.
Eitherway, New Fans are very expnsive. Will be hard to find one cheap, while not knowing if it fits or not.
I was just suggesting getting the 88 accord shroud.. not anything from koyo.. Also I dont suggest getting the 88 accord fan. It will be louder than youd ever want anywhere in your house. a Low speed box fan modified to work with the rad would be optimum.

Ebay sells many cheap radiator fans for mainly honda and toyota cars.
This resembles the table fan I used to test temps.
For US $27, it may work well. I dont nwo how to power it, maybe through some AC to Dc Adaptor with Variable Voltage.
Or a cheap radioshack AC to 3V Adaptor, and use join the wires to the adaptor jack.
Any ideas? Only way is to undervolt this thing I suppose.
Sweet lookin mod ther Zen. OT you live in Irvine! Im about 5 minutes from it (Tustin) :)
How are we doing here?
