Pelteir junction for liquid cooling

[Ghostrunner]

hi there i just wanted to ask, has any body tried using a peltier junction and a radiator to cool a cpu or gpu? if you want to know how a peltier junction works, here's a link to explain. http://www.marlow.com/resources/general-faq/6-how-do-thermoelectric-coolers-tecs-work.html

 

i have heard that peltier junctions can cool very well and i thought it would be cool to use one as a cpu cooler.

 

if linus or any of the members of LMG read this post, maybe consider doing a video on this idea

Peltier units can cool very well, but they also require a really good cooling system on the hot plate side. Otherwise the unit burns up.

 

Since you need a really good cooling system anyway, it's better to just use that to cool off the processor rather than using a Peltier cooler.

It's been asked many times before but it basically boils down to efficiency and being able to insulate the GPU or CPU socket to prevent frost or moisture. It's the reason why it's fallen out of phase as it was something that was available at the time, now if one wants to go sub zero going with a phase change system is more ideally suited.

I wish we could have seen that phase change case push the boundaries of the 4790K. I have said this even on the video itself (in the comments) and no response to that. 5GHZ is NOTHING on that case. You should have been able to get in the 5.6ghz + range with that chip and higher voltages. (Around 1.65v) 

 

I dreamed of seeing that.

For sure it can be pushed further but that wouldn't be something really recommended for daily use, at voltages that high degradation does become a real problem in the shorter term.

Degradation at that low of temps? I think not... 

 

How so? (Not trying to be rude but I don't believe at those temps you'd fall into the degradation category)

Degradation is a combination of multiple factors, temps and voltages being the main focus, where voltage is the thing that is really important. It can slowly cause issues with the transistors degrading as your pushing more and just wearing out from running at the higher voltages. 

 

For temps the CPU will throttle itself down to preserve itself, and with adequate cooling it will not have problems as in the phase change build.

OK... not nitpicking but I seem to have a different understanding then you? I guess? and I am going to call it out here because you may have a better understanding of it and I respect this but in the same sentence maybe I am also possibly right here?... 

 

" It can slowly cause issues with the transistors degrading as your pushing more and just wearing out from running at the higher voltages. "

 

The whole point of a phase change cooling is to change the "phase" in which a chip will run. When you icy cool down transistors, capacitors etc... such as the quoted case.. and alter the state it runs at to allow the higher voltages without damaging. I would consider degradation a factor if it WASN'T cooled by these means. 

(and not trying to steer too far off topic here... it relates to the OP. )

Phase change is the cooling system itself not transistors being changed, the fluid inside the compressor is changing phase basically causing a cooling effect while carrying heat away from the source in this case the chip. The idea you have for the silicon running at low temps would need to be much colder, close to absolute zero or super cooling them for it gain or change it's properties as a material.

So then the case is pointless because you're gonna fry your chips then?

Not necessarily, it's a niche product basically for someone who want an everyday sub zero system. For high voltage overclocking >1.5V it's more for extreme competitions like LN2 cooling to achieve world record results since you won't be running a chip like that for long.

I would love to run 5.4ghz on mine   I think it would be fine around 1.45-1.48v 
"ish"

 

This case did come to mind and i considered to have it be a daily driver as it is expensive the speed I would run at would be astronomical.

If you can run a stable overclock that is, 5.0Ghz is not overly difficult to achieve on skylake, it does get exponentially more difficult though once you start going past that requiring more voltage and extreme cooling options like the phase change case which would come into play.
