A stirling engine cooler, this is just cool.

It's a bit odd that MSI are announcing it as a CPU cooler but the pictures tell a different story.

 

Its a chipset fan, but anyway, thats FRIGGING COOL! if not a little gimiky.

 

Looks very 'natty' Wonder how many RPM's the fan gets too?

 

if i remember it runs faster the hotter it gets..

so if its screaming around then your mobo will soon die a treble death! nice acoustic warning! hehe

 

Depends on the chipset and its temperature, and a lot of variables.

 

Yup, the more heat coming from your chipset the faster the fan will go. It's a nice and effective dynamic speed control.

 

Cool idea but I doubt dc brushless + thermistor will lose much ground to it.

 

I love the stirling engine, why didn't i think of that?

 

I don't know, if it's refined to be rather reliable it could be a definate rival, especially if you can apply it to low-powered systems.

 

Damnit I knew about this first thing this morning but have just written it up

 

Now I want to Stirling cool everything, CPU, GPU, NB, SB, RAM, HDD, MOSFET's.

Some of the comments talk about the efficiency being overstated but one comment was probably correct, the whole cooler is probably 70% efficient but the Stirling engine itself is probably much less, like 7% or maybe more but even if the Stirling engine is only 7% that would still be enough, lets say the NB is outputting 20 watts of heat that means the Stirling engine is producing 1.4 watts to drive the fan, NB fans are only between 1 and 2 watts anyway so it will be fine.

Now if you had one made for the CPU and lets say the CPU is outputting 100 watts of heat then the Stirling engine would be producing 7 watts to drive the fan, most CPU and even case fans are 5 watts or less so again it would be enough to cool the CPU.

This is a great way of saving energy, a small amount but every bit counts.

 

Nice idea for self regulation. Now make the fan from brass, and make the rest of the board more steampunk

 

Nifty idea, helps to combat global warming

 

Now all we need to do is build a giant Stirling engine cooler and install it on the Earth, that should combat global warming.

Made me laugh
