3:55 Pro-Tip: When draining a closed liquid loop, open an air-intake near the top of the loop before opening the drain port. It'll drain faster, and flow more smoothly. By "more smoothly", I mean you will avoid the -glug glug glug- type of flow that causes the stream to alternate between gushing and dribbling as it allows air to enter through the same hole the liquid is trying to exit from.

@DCS_Garage Год назад

@blipman17 2 года назад

Yeah it turns out that thermal conductivity doesn't matter for a transfer fluid that much. The thermal conductivity mainly comes from the metal waterblock, which can be enlarged or shrunk quite easily to have better heat exchange with water. What is needed is thermal capacity in the water to soak up more heat, or a bigger pump. If you'd want any reasonable increase in performance and have thesame tubing and waterblock setup, you'd need to swap the liquid out to ammonia.

@boiledelephant 2 года назад

And then your PC would smell GREAT

@AkamiChannel 2 года назад

That's why I use my own piss as coolant

@misterjonas6991 2 года назад

Why ammonia? I mean, yea, if you turn the whole thing into a refrigeration cycle that would do, but as a liquid ammonia has about half of water's heat capacity. Actually, water is just about the best medium for heat transfer between 280 and 400-ish K you can find. Nothing (I know) beats its heat capacity. You're right in that a larger pump would likely help out more just because it helps with the temperature gradient in the block. However, I suspect the bottleneck in this particular system is the water/air transfer, mostly because it always is. In fact, the higher conductivity liquid would probably show the largest improvement in settings where the pump is severely undersized. Any flowing liquid will form what's referred to as a "boundary layer" on solid surfaces, which is essentially a stationary film that heat must pass through by conduction rather than convection. This boundary layer is thicker when the flow velocity is lower.

@blipman17 2 года назад

@@misterjonas6991 About the heat capcity of water being higher? Depending on the temperature, ammonia has a higher heat capacity per litre. It defenately has higher heat capacity, but it's less dense. Point is, you don't really have to care about heat transfer that much if you're cooling to such extreme colds.

@Keri-Kerigan 2 года назад

A 1% graphene addition to cooling fluid increases thermal conductivity by 61% and reduces viscosity by 31%. Note: is really only useful at high flow rates to give benefits over other coolants as it absorbs/dissipates heat quicker, but has identical heat capacity. What we would have needed to see in this test, is a high-flow pump setup, as you don't get the max benefits until you hit around 6L/m flowrate to take advantage of the increased thermal conductivity of the fluid. In addition, you could probably use a single pass high flow radiator for increased performance with this fluid with its higher heat transfer rate, instead of the 2 pass rad installed.

@chincemagnet Год назад

I regularly work with a variety of chemicals, including anti-foam. And the problem with anti-foam is it leaves behind a residue if you use too much of it, or when it dries, which would insulate the inner surface of your loop, preventing, or at least impeding thermal transfer. Your best bet is to simply design a loop that can be vented, and is properly configured to minimize foaming, which mainly just means there’s as little air as possible in the system.

What did they say about the resistance across a little distance of coolant ? I would have thought graphene would act as wires if it really changed the water? I think its such a tiny amount added to make it go black,that the electrical conducivy didn't change much. The fluid will just be glycerine or something, which will just boost specific heat a bit... Or its the antifoaming agent only making a change?

@darkavenger10k 2 года назад

I think you would find a larger temp change with short burst loads rather than sustained load. As with most water loops once the fluid has reached equilibrium you are limited by how much heat can be removed by the rad/fans.

You should do a long term (6months or so) of constant use with a heavy load put on for like 3-4 hours a day to see if the heat causes the graphine to solidify to cooling fins in a cpu/gpu water block and since its more viscous and heavier per millilitre than distilled water and see what wear/flow it does on the pump

not really, this isnt the type of foaming they are meant to prevent, i made a post apart, the liquid is meant to prevent cavitation bubbles, these are bubbles that generate due to the drop in pressure in certain parts of the pump, they are an issue because when the pressure rises back up they will implode, and the incoming pressure of the liquid will be like the tiniest pistol shot ever, ohh so slightly eroding the surface in which the cavitation bubble had happened.

@@revdarian That's a good point, but i think those would form from shaking a bottle aswell. Though I'm not sure about that.

graphite is technically a lubricant, so I would guess that there shouldn't be any issues with additional mechanical wear... settling is a legitimate concern, but graphite building up in the cooling fins could hypothetically improve thermal transmission, however depending on the size of the microfins blockages might be an issue over time... if instead of graphite, you had nanotubes and older generation fins in the loop, there could be a benefit to nanotubes getting caught in larger fins and increasing their surface area. If they're feeling insane, a water loop filled with gallium would be a lot of fun to see. especially if some "accidentally" uses an aluminium part...

@SovietGrazz 2 года назад

@@davidpretorius2984 No, obviously graphene settling in microfins wouldn't improve heat conductivity, because you're reducing surface area AND/OR increasing flow resistance, and you're also adding material between the copper and the water, and thus reducing overall conductivity even if the thermal conductivity of the material is pretty good. Imagine for a moment coating the exterior surface of the fins on a standard air cooler in graphene. Even if that increased surface area, would that help heat conductivity? Obviously not. At the micro-level it's much worse, roughly analogous to filling most of the gaps between the air cooler fins with graphene and choking flow.

@erico7245 2 года назад

@@SovietGrazz the thickness is literally one molecule, however. And the thermal conductivity isn't "pretty good" it's off the charts and better than anything it's coating. IDK, it seems to me that if you look up graphene coolants for other applications (because they are out there) a coating of graphene on the interior surface is the point. In fact, several applications go so far to say that after being internally coated by graphene coolant the performance of the radiator increases and will eventually lead to much more efficient radiator technology in the future.

@@blahorgaslisk7763 Evaporation rate shouldn't be an issue since it's inside a closed fluid system.

As for suspension I don't think just having the fluid circulating is any guarantee that there wont be deposits. Just look at all the opaque liquids available. It seems most of these has a problem with deposits building up over time. Now this is one thing that might be less of a problem with this new fluid as the graphene should be extremely light and the particles very small.

A longer-term test would be great to see because it does look amazing even if you ignore the marginal cooling efficiency improvements.

@macledou 2 года назад

Okay, so I've worked with graphene liquids before and the reason why it foams is due to the dispersant and the stuff that keeps it in suspension.

Id like to see them try the automotive coolant additive called "water wetter", they claim up to 20°F cooler temps when used in a car.

@animefreak5757 2 года назад

the issue is the temperature delta. In a car the coolant is around 100c (212f), and ambient air is going to be, let's say 25c (or 77f). That's a 75c (165f) difference between the coolant and the air you are trying to dissipate heat into. In a watercooled rig what's the delta between coolant temp and ambient? 10, may 15c (50-59f)? There's just not all that much improvement to be had from the coolant itself. Even differences in the radiator itself are going to be minimal with those kinds of delta numbers. I'm sure water wetter would help, but the difference it will make is going to be very minimal. If we want to see significantly lower core temps, we need to either improve the thermal conductance of the die itself, or go sub ambient.

@BixbyConsequence 2 года назад

@@bilateralrope8643 I thought so too, like integrate it into a new "heatsink" design

this is not correct at all, please do some research on nanofluids. the heat transfer mechanism is still up for debate but there are very concrete gains in conductivity with nanoparticle suspensions. that being said i would never put them in a pc cooler as suspension stability is the hardest part of the equation - an engineer with research experience in nanofluids.

it wasn't, that is just an optical illusion

To be fair butter doesn’t cut very well. It’s just not sharp enough.

Can we see a long term test? I want to know how the particles would drop out of suspension.

been using my stuff for over a year and is still working normally, leaves less residue than some dyes and all opaques.

Have you guys done any testing with Nano Fluid? I tried it and was pretty impressed but then I'm not a tester tech and don't know what I'm doing, so my view doesn't count. I would like to see a review outside of the lab testing. I think Mayhems has some but the one I used/have is Ice Dragon and it shows about a 10o decrease.
