Why don't we have pumpless water coolers yet...

Why don't we have pumpless water coolers yet? All it takes to work is two valves and a fluid with a high thermal expansion like ethanol.

Aye lemme just cool my electronics here with a volatile liquid lmao

Probably for the same reason there aren't too many fanless air coolers, even a small bit of forced convection gives you a large improvement in cooling capacity.

You could do some kind of phase-change evaporative thing I guess, ethanol boils at a bit over 70C. Essentially a giant heatpipe. But if you're content to keep your CPU to around 70C then you might as well just use an air cooler and have done with it.

Because the expansion is too slow and the temperature difference is as well. Slow movement of fluids would result in equalizing the temperature, rather than only one fluid loosing heat.

Other people have tested it already and you're just dead wrong

>not just using tap water open cycle

Thermal expansion happens across the entire temperature curve, not just at boiling point. You know how glass bulb thermometers work so well you can measure a difference of 1/10 of degrees? Heating it is enough to create a "movement", so to speak, but there can be no bubbles as the air is compressible.

We have. This one i also fanless so it needs 30 kilogram heatsink as well.

Because this isn't required if you use AMD processors. Also even with kind of extremely cooling you also have to undertake the dangerous procedure of deliding intel processors even on soldered ones which always runs the risk of killing them in the process.

IMHO just get a 2600X with a hyper 212 and good 3200 CL14 RAM to get 95% the performance of intels latest blazing infernos. Is expensive exotic cooling and risking destroying your CPU with a botched delid job REALLY worth that 5% higher FPS?

The shills are at it again

>buy freezer
>put large bottles of bottled water inside (alcohol is better but more expensive)
>put desiccant to extract moisture from the air
>put computer inside and carefully insulate the cable hole to prevent air coming in or out

Explain why this won't work. Condensation will not be a problem because of the desiccant, and heat extraction rate being too low for the cooler will not be an issue because there will be massive heat sink available in the form of -20c blocks of ice or liquid. If the machine is turned off occasionally and not blasting prime95 24/7 the heat will never be high enough to raise ambient temperature too much.

It works better if you fill it with oil

>use the CPU with better performance per watt for less heat
user is right though.

power bills?
dunno
not sure how long that desiccant will remain effective either

I have a 2600X and a H115i. :3

If there's any leak with (conductive) water everything'll blow up anyway.

I doubt this will work effectively, and by the time they do make it effective, there will be a better method of cooling available.

Yeah but you'll have difficulty using that thermal expansion to create enough coolant movement to do anything worthwhile, is what I'm saying. Whereas it's easy to move coolant with a pump.

M8 you know it's true. My i3-8100 regularly reaches 80C under load on a hyper 212, can't imagine how bad the i7-8700K would be with this cooler.

Because I use one

>Why don't we have pumpless water coolers yet?
Because they're inefficient and make noise.

>Condensation will not be a problem because of the desiccant
You would need a lot, especially because they work worse in the cold.

>and heat extraction rate being too low for the cooler will not be an issue
Fridges are made to keep things cold and occasionally cool down room temperature things. Not cooling 100-500w heat output. Maybe a good freezer could stay pretty cold, but it will be loud and use power.

>there will be massive heat sink available in the form of -20c blocks of ice or liquid
The liquid would need to be in some kind of heatsink-fin container, made of a highly conductive material in order to have a big effect.

Which leads to the question... Fucking why? It'll be huge, bulky, loud, expensive and complicated. All you're getting out of it is 40c cooler ambient temp, probably much less under load as the air heats up.

>tfw heatsink is dusty and too lazy to clean it
>just reduce overclock when cpu hits 100% and temps hit 75C

house fires.

Then use non-conductive cooling fluid like has been around for years

IMMERSION

COOLING

Yeah but it won't ignite and burn down your house

>(((conductive)))
name the jewz user

Doesn't exist. After a few months the ions from bare metal make it into the liquid

This. You can't move shit with it

so then just suck the air bubbles out with your mouth ya dambgus

>increase power bills by 9001% and fuck up your freezer's compressor by running it continuously using one simple trick
You do realize that you'd be ultimately dumping all the heat into your freezer's radiator, right? You could save yourself a lot of hassle by just running a water loop throught that instead of doing all this autistic shit.

I might be wrong, but I'm gonna guess that this happens in an unimportant scale.

I have a pumpless liquid cooler. Not water though, water isn't the greatest for liquid cooling

show me a good 3200 CL14 RAM to buy

It's never important to begin with unless you're dumping water all over your parts. I've had a 40 antifreeze 60 tap water mixture for 3 years and it's still very clear and flows great

I thought pretty much all 3200 CL14 was b-die?

This, or just keep your pc in your kitchen and cycle cooling lines through your freezer
