Theoretical Overclocking Cooler

Rally0078 · Jul 27, 2014

Think of Helium at 25 ATM pressure as a liquid. is it possible to make it circulate in a custom loop for overclocking?

Someone Somewhere · Jul 27, 2014

People cool using LN2, but only usually for records.

Condensation and where your dump the heat are the issues.

Hi
Theoretically yes but practically no.
You would have to cool the Helium to -269 C to make it a liquid.
A cooling loop to take temperatures that low would be difficult as things become brittle at those temperatures and then to add a pressure of 25 Bar to that just adds to the problems and best of luck getting a pump that would work at those temperatures and pressure.

This isn't theoretical it is actually in operation right now, and probably much safer.

4Ryan6 :

Yeah but thats water cooling not helium and can run at 13 C below ambient not nearly 300 C below ambient there is a huge difference.

4Ryan6 · Jul 27, 2014

makkem :

Of course there is a huge difference and though it cannot reach 300c below it can go sub zero with motherboard insulation and running anti-freeze type of coolant and is much cheaper than attempting to incorporate and maintain running liquid helium circulating through a cooling system.

Assuming he would like to circulate the liquid helium for a 24/7 overclock, if not and it's just a one time high clock usage he may as well stick to LN2, disregarding any cold bugs he will encounter.

Yeah you are totally correct and it is a much more practical to use a Peltier or even liquid nitrogen.

Rally0078 :

I would suggest seeking information from overclock.net as there are many more projects closer to what you may be considering there, as for Toms Hardware, I am already considered over the possibility line of insanity here with my cooling, much less anything that extreme.

makkem :

I actually run a 10c water temperature and have fine tuned the system I'm running to run at 15c below ambient and right now I am 15.5c below ambient and it is allowing me to run a 5ghz 24/7 stable overclock of my 3770K without it being delidded, check the CPU-Z validation in the sig.

I control it to run at 10c as it will go much lower than that but I am operating above the condensation forming temperatures and have no condensation problems at all, not bad for a system that always runs below ambient.

Rally0078 · Jul 28, 2014

Ok leave that Helium. Is it possible with LN2 in a loop?

Someone Somewhere · Jul 28, 2014

Not really. The main thing with LN2 is that you use the heat from the CPU to boil it.

You can't really keep it cold; you just condense more and use it to replace the stuff you've boiled. And making it as fast as you're using it would be tough.

Rally0078 · Jul 28, 2014

Is this configuration possible? Those Copper tubes Connected to a refrigerator compressor. Dont mind those condensation things and blah blah. Will IT WORK?

Rally0078 · Jul 28, 2014

Ok ROOM TEMPERATURE -196 C???? Possible? in Vaccum

Someone Somewhere · Jul 28, 2014

No - there's nothing making the coolant evaporate in there.

You'd also have to get hold of a lot of refrigerant.

Rally0078 · Jul 28, 2014

Without that coolant evaporate you cant overclock???
Circulate the coolant at extreme pressures and temperatures. it will cool down the heat sink

Someone Somewhere · Jul 28, 2014

It will then heat up, try to boil, and just keep on increasing pressure until something gives. How many thousand PSI can your pipes handle?

And if your coolant is flammable, you get a BLEVE. Which you really don't want.

Rally0078 · Jul 28, 2014

ok then put a blowtorch in Liquid helium at - 220C

Someone Somewhere · Jul 28, 2014

It will rapidly boil off, and the He gas will put out the flame.

Rally0078 · Jul 28, 2014

A cooler(Dry ICE) to cool the hearsink?

Someone Somewhere · Jul 28, 2014

Dry ice is a bad choice. It's a solid that will sublimate straight to a gas, so you can't easily transfer heat to it.

LN2 is a better choice, but you still need a large source if you want to use it continuously.
