nanofluid!

[relttem]

I just shook my head...we are still trying to track down an author of an article in there most recent issue..or last months.that wrote an article about water cooling.

[skinnee]

Well, once I get everything tested, I'll register and post my results there...I could care less if they ban me for posting a test report.

[skinnee]

Testing is in progress!

I am going to take multiple runs of distilled and nanofluid using the same CPU block mount. This way I keep as many things constant as possible.

[relttem]

good work, Skinnee...ever hear of the band 2SkinneeJs?..check them out

littleowl?..bob?..c'mon

[skinnee]

good work, Skinnee...ever hear of the band 2SkinneeJs?..check them out

Yup, thats where the spelling of my nickname came from. I had the chance to see them perform a few times when I lived in Nebraska for a couple years.

Onto Nanofluid run #2.

[littleowl]

good work, Skinnee...ever hear of the band 2SkinneeJs?..check them out

littleowl?..bob?..c'mon

I know I need to test a little more! I am working on it so to speak.

[relttem]

it will be interesting to see if Skinnee gets even something similar to what you had initially found.

I saw the Js so many times back in SC..they just played here in DC a month ago...I think they did a short re-union tour.

[skinnee]

Dual Core tests complete. Crunching the numbers and doing the write-up...Dual Core results soon.

[skinnee]

Well, here is the shortened version. I need to take some photos for the full review and test report that I'll post in the LC section here and a few other forums. But here are the details. Keep in mind this is only a dual core, I will be adding a Quad to the test bench and running the tests again to track a much higher heat load.

Test Specifications are detailed with each of the data tables and graphs. Each and all tests was performed using Prime95 version 25.7 using In-place large FFTs for a 15 minute warm-up period with a logged test cycle of 60 minutes following the warm-up period. Ambient temps are averaged between two different sensors. After each test a 30 minute idle period was observed before starting the next test.

High Flow: Very close, averaged temps are 0.35ºC and 0.33ºC difference for a 60 minute load cycle with Nanofluid having a 1ºC advantage on max core temps for the test cycle.


Medium Flow: Medium flow produced strikingly similar results to High flow, Nanofluid has a lower Max Core Temp by 1ºC, and the difference between average temps shrinks to 0.24ºC and 0.25ºC. At this point its looking like a real duel.


Low Flow: High heat loads is where the Nanofluid really starts to outpace Distilled. Nanofluid still grabbed the lower Max temp by 1ºC, but the average temps were what really stood out, Nanofluid has a 1.39ºC and 1.42ºC advantage in average temp and a 2ºC minimum temp advantage.


The low flow tests really makes me eager to put the fluid through a much longer and more rigorous set of test runs with a Quad due to the heat load being higher, I have a feeling this is where Nanofluid will pull away from Distilled. I also plan on doing multiple runs of the same test settings with a quad, this will allow me to see if there is any major deviation from run to run for the same test.


A big thanks to relttem and his business partner for supplying the Nanofluid, was a pleasure to test your product on this first run and will be just as enjoyable for the quad runs! Also, thanks to littleowl and Hicks for pressuring relttem into involving me in the test.


Since you guys get the first view of the test results and the way I am presenting the data, let me know if this form of presenting the data works or needs changing. Also, any feedback is greatly appreciated.

wow! very interesting results for 'first run'

I too would be interested in seeing a longer test period for the low-flo test.. & a quad as well

thank u muchly for time & effort!

edit: btw the graph & results etc are easy to read & legible - good stuff!

[BlueAqua]

Great work Skinnee. I find it quite interesting how much flow didn't matter in your tests. This needs to be investigated further.

The CrystalFontz really helps monitoring, and with great consistency of ambiants. I'm impressed.

[relttem]

good work. I was wondering if you were able to overclock at all? I see you mentioned 'high' heat loads, but I am not sure what that means. And, do you know what your flow rates were?
We think the nanofluids will really come into play when the CPU (or whatever you are keeping cool) begins to get hot - as is the case with overclocking. The nanofluid will be able to remove more heat than the H2O. Therefore, as littleowl saw, the temperature of whatever you are overclocking will be able to remain cooler for a longer amount of time and let you overclock it more. What do you think your next steps/tests will be?

Thanks again, Skinnee..it looks good. I am will be waiting to see more results.

Bob - your turn.

[littleowl]

OH I want to do some more testing but I cant get things moved around here

[[XC] Hicks121]

Good testing brother!! Keep up the great work & Im lookn forward to the quad tests.

[CyberDruid]

Nice Work Skinnee. If indeed your set up was kept consistent it indicates that there is something (finally) with a better coeffiecient than distilled water...which is surprising.

[littleowl]

I also would like to see some OC.

Great stuff Skinnee. Waiting for Quad runs.

[skinnee]

Thanks!
A quad will add more heat to the loop versus a dual core at the same Vcore...more cores = more heat.

I went straight to OC'd on the E8400, 4.275GHz at 1.52 Vcore.

And, do you know what your flow rates were?

I did not have a flowmeter in the loop, that should be arriving any day now. I will included measured flow rate in the Quad test.

Yup, the max core temp on the nanofluid was a lower, I really need to get a quad in my test bench and run the tests again. This time I will do multiple runs (3 I think) of the same test and record the standard deviation among the tests. With equating the standard deviation I will be able to see just how consistent my tests were.

First, I need to round up some coin and buy a Quad for my test bench, but once that is covered I will be doing a Mini CPU block roundup, and will do some more distilled vs. nanofluid tests using a different block, one that doesn't have the performance of a Fuzion. This should also increase the temps and show a bigger difference in the numbers...thats my theory anyway.

Thanks again, Skinnee..it looks good. I am will be waiting to see more results.

Bob - your turn.

Thank you!

Nice Work Skinnee. If indeed your set up was kept consistent it indicates that there is something (finally) with a better coeffiecient than distilled water...which is surprising.

Thanks! I tried to keep as many things constant as possible, no block re-mounts, no settings adjustments, nothing. I kept everything constant except for the fluid in the loop.

Everyone, thanks for the feedback and kind words, makes the testing worth it knowing you all got some information out of it!

I need a quad for the bench...gonna have to get a sugar momma on the side.

[littleowl]

hey you find that sugar momma make shore you send her my way also!!!

[relttem]

Skinnee, can you do some bench marking?

[skinnee]

Skinnee, can you do some bench marking?

Sure...what did you have in mind, anything specific?

[relttem]

I ran a bunch of standard benchmarking programs to push the chip a little and compare results. Another thing, if you can manage, would be see how high you can overclock with the nanofluid v's the H20 - as long as you feel safe doing it. I do it with my AMD chip all the time

[skinnee]

Yup, I need some more HWBot points anyhow, plus I need to learn more on this board...I'm a noob on DFI boards.

[relttem]

I thought of another thing that would be nice to see: a simple block diagram of the test rig and where the temps are being measured. I want to crunch some heat transfer numbers, but I need a set up to get a rough idea of what is going on. And, like I mentioned earlier, flow rates (even estimates) and tube size.

thanks

Well...I've been doing some bench runs. I have to say, this is completely non-repeatable tests and I cannot even compare the fluid to distilled, the order of the bench apps run and crashes and everything else cannot be exactly reproduced for comparison. I won't put out numbers like that...its completely against my test methodology.

Attached is a pic of the test loop. Loop order is as follows.

Rad Oulet -> CPU Block -> Res -> Pump -> Rad Inlet

I do not have water temp sensors or a flow meter presently...flow meter should be here Monday. All of my settings and equipment were on the header of each graph, but temp sensors are on each rad fan for intake and exhaust of the rad fans. I will be able to give you exact flow numbers once I get the flow meter on Monday.
