Progressive peltier cooling device

[Mouse-Potato]

I was wondering if anyone has had any experience with peltier systems. I am curious about the benefits of a peltier system that is electronically controlled by temperature.

 

Wouldn't it be more beneficial and economical to have a system that has a electronically controlled CPU temp detector that varies the amperage of a peltier system to get a nominal setting for the CPU, it could be cooled by a 240 or 360 mm water cooled system to dissipate heat.

 

What are your thoughts?

 

Would this be feasible and more compact than a compressor chilled system that costs only a fraction than other systems?

it would be more compact, but nowhere near as efficient. peltier coolers take quite allot of power to get decent results. I have seen them used to chill water in a water cooling loop instead of being directly on top of the cpu which may be a better way to go about it.

Nowhere near as efficient compared ti what? Liquid nitrogen? What energy consumption compare to other devices?

I have used some small thermometric generators, but you need some serious power to get good temps, but it could work.

its 1 watt per watt of heat dissipated. i have a coolit elite with a bad pump but it the actual peltier unit definitly works great

So if you want to cool a 90W TDP(intel i7) with a peltier system that runs a low temp only once and a while when multi threading or on full load. Basically set a target temperature that you want, lets say 10°C, the device automatically detects the CPU temp and adapts the amperage to the peltier unit. I think it could work like a supercharger system on a car, except instead of horsepower it would be heat dissipation.

That would require the peltier cooler to be 100% efficient which they are not. Peltier coolers are only roughly 15% efficient in a good environment, so the power needed to adequately cool a cpu would require a few hundred watts of power.

nope 100% all the time

[Mouse-Potato]

nope 100% all the time

So you'd have to run an extra 90 watts all the time to cool the CPU even if it's idle?

yes

unless you use a potentiometer or something

So if you were able to sandwich a thermally efficient monitoring system that could regulate a peltier system to match a temperature that was predefined by the user you'd have a system that is more efficient than a refrigerated system, also it'd use less space. No compressor, or refrigerant pumps, etc..

If there was only a way to make peltier systems more efficient than they currently are.

yup. I would recommend 150w+ systems

They have got a lot more efficient over the last 10 years but they still aren't near perfect. For example with an 80w peltier, you would be lucky to get 8w of cooling ability.
