The fanless heatsink.

The fanless spinning heatsink: more efficient and immune to dust | ExtremeTech

OK, how do I adapt this to my engine & AC on my 911?

The fanless spinning heatsink: more efficient and immune to dust | ExtremeTech

This new technique is so efficient that if these heat exchangers can find widespread adoption in computers and air conditioning units, Koplow estimates that the total US electricity consumption could drop by 7%.

It looks like a good idea.

Maybe this can be used in electric cars as well.

Interesting but seems kind of gimmicky, for cpu/gpu use. Most likely will be priced far to high and at that point it would be better to just go with water cooling.

I did just overheat my 4890 the other day though :X

So, instead of a plastic extruded fan with a mini motor and fin cooling surface, we have a highly machined, heavy, aluminum disk which has to maintain a 0.03mm gap with the air bearing. That sucker will have to be FLAT! SUPER FLAT!

It ain't gonna be cheap. Now apply this to an A/C unit with heat transfer requirements on the order of magnitude of 100 times. You need pounds of aluminum super balanced!

Do these people have any idea what this will cost?

[red-beard]

My opinion is confirmed. It is a CNC machined disk of AL-7075. That is some expensive stuff. And it is under extremely high tolances. Also, from their own thermograph, the thermal resistence of the air bearing is not negligible.

Wow, bad science.

Give one to a smoker for a year and then I'll believe the "immune to dust" claim.

[ErVikingo]

we could attach one to the oil filter in our cars and ........

That's what I was wondering, how will a moving part compare in heat conductivity vs a thermal paste + a stationary block.

[red-beard]

Here's the Thermograph

[RWebb]

hah!

More efficient with a water-cooling system...

[scottmandue]

When I started as a tech... CPU's heat sinks didn't have fans...

I'll be in my cave feeding the pterodactyl if anyone needs me.

[island911]

How is it NOT a fan?

[island911]

Dyson will put it in something w/ clear plastic...

[scottmandue]

“Thermal Brick Wall” that is preventing computer chips from moving beyond 3GHz

I though the 3GHz "wall" was because above that frequency things go microwave?

[island911]

I'm just going to mount my cmprt to a ceiling fan blade ... so it can be also cooled w/o a fan. ...won't collect dust that way either.

does it eat punch cards?

If the software and o/s guys would figure out multithreaded code, there'd be no need for >3GHz. For certain tasks like communications and networking, also graphics of course, they get stunning performance from parallel processing on multi-core chips (64+ cores).

[Scott R]

This uses 2 watts, a standard CPU fan uses 1.5 to 1.9 and costs a lot less to produce, with adequate enough cooling to be mass selling PC's. Looks like snake oil,

[Brando]

Just because they're doing something differently doesn't mean they're doing it better.

As for the multi-threading... I believe many blends of *NIX have been doing multi-threading for some time.
