nanofluid!

[D_A]

Yes ... the nanofluid. How is that working out?

link to where can buy?

I do not know of anyplace to buy it as of yet. The guy I got it from has created a name and is trying to get on here to reply to people and explain more.

He may have a ready market here.

[littleowl]

I want to see mcoffey or someone do some hard testing of it before he would start selling it.
I am also waiting to see what 123bob has to say about it. he also has a nice bottle of aquafena (sp?)

this is really nice, we can start buying it

[littleowl]

you never know xtclocker. It may not be worth buying! We need to get some heavy testing done to see.

[karl_eller]

I'd definitely consider buying some provided that it:
1) Gives a definite improvement in temps over distilled water (obviously mileage will vary depending on where the heat limitations are in each particular loop)
2) Has enough anti-microbial properties that you don't need to add anything else to the loop
3) Will last a decent amount of time (9-12+ months) without needing to be flushed and changed
4) Can be flushed down the drain or disposed of in some similarly easy manner.

I can now answer some of the nanofluids questions..

We have had some on the shelf for almost 6 months. My partner has had a bottle of it at his house in his shed for almost as long. We have notice no microbial growth at all. The DI water will also help with the growth. We will look into the amount of the chemical needed to inhibit any microbial growth and see if that is less than what we have mixed.
With all the samples we have sent out we are hoping to get a good idea of what the capabilities are versus regular water. Of course this will depend on system as a whole..ie..if your radiator is too small, then it will peak out.
I really don't see any reason that it would have to be changed at all. The nanofluids can't break down or decompose. As long as the system is closed and leak free it should be good for quite some time.
As for being poured down the drain. The MSDS sheet received with the concentrated nanofluids say not to pour it down the drain. We will have to look into what concentration is safe for disposal.

Hopefully, littleowl will get some results soon, as will some of the other places. I currently have it in my system now without any problems, but I do not push the computer...that is why we wanted to send it off to people/labs more capable of that.
I am going to work on a graph to post based on some pump flow rates. It should show what kind of enhancement littleowl might expect due to his diluting the mixture. I will try to get that in the next few days

relttem,

I have the bottle you sent. It will go in my main rig this weekend. We did not have any guidance as to how to use it. So that I'm clear and you get good data;

1. Do I use it 100% concentration, just as you sent it?

2. I suppose we do not want to put in any additives like antimicrobial stuff? Just the pure fluid, for out test, right?

3. Toxicity. I'm not planning on drinking the stuff, but what if the cat likes it? I need to know a little more here. I'm not afraid of it, with all the other chemical stuff I use, but I want to know how bad it might be. (I.e. If I decided to do shots of the stuff, what do I tell the folks at the hospital???) You've said not to pour it down the drain. What would be the proper disposal method?

I'll collect "before" load and idle and ambients, then "after" load and idle and ambients. Anything else you want to see?

Thanks and Regards,
Bob

[relttem]

yes, we sent you our optimum concentration, so do NOT dilute it. I'd drain your water out and pour that straight in and follow the rest of the cooler's instructions - no air bubbles etc. I am pretty sure your cat won't like it. You can handle it, get it on your hands etc, but don't bathe in it or drink it - as you said. Pretend you are handling anitfreeze or dishsoap. When you are done wash your hands.
what we want to see is a comparison. So, if you could run your current set-up thru some tests and mark down what your temps/MHz are etc and then run thru the same tests with the nanofluid. Over-clock if you can. I bumped my FSB up, ran some bench marks and temp readings..then did the same with the nanofluid. Anything like that would be great.

We appreciate it.

thanks

I can perform the tests if mcoffey is busy or booked on block tests. I have a similar setup to mcoffey and Martin, I just don't have the experience under my belt they do.

[123bob]

OK relttem. Will do.

Don't forget to tell anyone else testing this on other forums to carefully measure ambients as well as the run temps. Our test data won't mean much without it.

I'll plan on testing a matrix of test points.

@Stock clock - before and after - load and idle

@My max crunching overclock - Before and after - load and idle.

I should have results late Sunday, with the weekend schedule I have. I'll post them here.

Regards,
Bob

See that is my problem I cant control the ambient temp at all.

[tiro_uspsss]

this is exciting!

[123bob]

I don't think you need to control it, just be accurate in recording and measuring it when you test. If you test at the same point, we can adjust the data to account for variation in ambient.

Just thought of something, I might add.
When using a nanofluid, wouldn't it be like super conductive?
So I'm scared because if you get a leak, and the computer's on, it would like.....fry everything.

[karl_eller]

See that is my problem I cant control the ambient temp at all.

You don't need to control it, you just need accurate measurements of the ambient temperature. If we were to compile all the results, they'd most likely be reduced to deltaT (the difference between CCPU temp and ambient or liquid temperature).

[Movieman]

nanofluid;
Is that what us old guys get when we get too excited?

[Gamekiller]

I wish I had a loop to test this stuff out in because it sounds very promising to me.

[karl_eller]

I have a loop (and holidays soon, so I'd have time), but I don't have the knowledge or the testing equipment (by testing equipment, I mean good thermometers both in-line and for ambient) (or the patience, for that matter ) to do a proper test with it.

Eller

[relttem]

it is no more conductive than DI/distilled water..on that note, if you dilute it you need to use either distilled or DI water. You don't need to worry about it spilling anymore than water. If it leaks..shut down, and wipe it up.
Ambient is important to keep track of, but if you are in an air-conditioned/heated room it should be pretty constant..as long as your system isn't by a vent. You want to make sure the same apps are running etc. I restarted after each benchmark to clear everything. My MSI boards has an applet that will automatically step up the FSB and test for stability. The problem I ran into was I maxed out the FSB and ran into hardware issues before I had any problems with heat. Based on what we did for our research project this should work like a charm. We will see soon enough..I hope

What we think will happen is that plain water will reach its max heat removal earlier than the nanofluid, thus not allowing you to push the chip as much.

thanks

Correct, if tests and measurements are valid, you will see a linear rise or fall of the liquid temp, core temps, etcetera as the ambient temperature flucuates. Well, as long as core load, voltage, fan speed and flow rate remain constant.

sub'd... Can't wait to see some results
