[ENG] Novel Concepts' ThinSink claims title of world's thinnest air-cooled heat sink - Page 4

post #31 of 54
Quote:
this low-profile ThinSink has a volumetric cooling efficiency 25 times greater than today's best microprocessor heat sinks, which means it cools 25 times more heat per cubic centimeter
The claim is 25x the volumetric cooling efficiency, NOT absolute cooling efficiency. It's stated a bit misleadingly in the article, but the press release makes this clear. So they claim that cooling performance per cubic meter is 25x that of the best heatsinks out today.

It's very possible to meet this claim given that the cooler occupies the volume of a credit card plus a small motor, I'm guessing on the order of a few cubic cm. Think of how much volume a Megahalems or TRUE occupies, probably on the order of several hundred cubic cm, and maybe 1000 cubic cm including the fan(s). Obviously, I don't have access to their data to know for sure. Even current notebook CPU coolers are much larger than the ThinSink. It probably won't result in lower temps, but to be able too achieve the same temps in a much smaller cooling package is a big deal, especially in the mobile segment.

Also, consider the fact that 2.73 degrees C per watt on a 25W TDP notebook CPU today would mean that the CPU would run at 68C above ambient temps at full load.

Remember, they're not claiming 25x the cooling performance... they're claiming 25x the cooling performance PER VOLUME of the cooler.

I don't think this will work. Like another poster said, the surface area is too small to shed heat well, and even if it has a vapor chamber I doubt it would work well, and shelling out 750 bones just to TEST IT?? Scam alert is right.....

Edit: To the post above, even if it has a massive amount of flow through it, you only can reject the heat as fast as the material can conduct it.

I was mostly addressing the "25x the cooling performance is BS" posts.

And while it is true that you can only reject the heat as fast as the material can conduct it, you don't need a breakthrough material to conduct heat effectively across something that's about the thickness of a credit card.

The company claims 25x better cooling efficiency, which does not necessarily have to translate to actual performance. Part of this is marketing no doubt, but the company could technically mean this heatsink performs 25x better than another heatsink that's the same size.

The ThinSink's claim to fame is that it's only .75mm thick, and cools with much higher efficiency than conventional heatsinks. That doesn't necessarily mean that it'll keep a processor at 2 degrees while a regular heatsink keeps it at 50 degrees. Tape a piece of metal .75mm thick to a processor and see what it does to help your temps - absolutely nothing. If the ThinSink can keep the processor from overheating, then technically the company can say that it's 25x more efficient blah blah.

In the real world, if this thing actually makes its way into a real product, we may not see much difference in terms of temperature. But it's a step in the right direction in terms of allowing adequate cooling in thinner products or better cooling in the same form factor we have right now.

This is an article about a new conceptual product (heck, the company's even called Novel Concepts) that may be a step in the right direction toward better and more efficient cooling. The idea in itself is cool enough (pun intended ), and the concept may be based on the Tesla Turbine from what I can gather. I don't understand why people feel the need to hate on something they know nothing about, based on 0 testing of their own and no apparent expertise in the subject matter.

I don't understand the bolded part.

The surface area might be small, but the surface area to volume ratio is going to be relatively larger because it is thin. Also, TDP's are rated with the IHS taken into account. If a CPU is rated at 25W TDP, that means your cooling solution needs to be able to remove 25W at the IHS.

Assumption on your part. No where in the article does that statement exist, nor is it implied.



Actually, it's "TOO EXPENSIVE for a product that looks like a scam, with no scientific data (especially independently collected data by respected sources) to back up their outlandish claims."

But, if you like. Go right ahead and buy one for testing.
No, you clearly didn't, otherwise you wouldn't be making remarks about people actually buying it. Also, irrelevant information, but nice try, trying to flaunt.

Assumption? No, that would be to take information as a given. A consideration, yes. I said PROBABLY.

You're one to make remarks about assumptions when you assume I want to buy one. The point is you make derisive remarks like that when the product is clearly not meant for the mainstream market at this point. Let me quote you:

Huh, so even if it goes into mass production (for use in popular devices) it'll be $750? You assume that the cooler will be consistently priced at $750, I can see why though as every other pre-produc- oh wait. The article clearly states,

but the company promises it will be cheaper in larger quantities
Honestly, I'd say you were a troll. Feel free to assume more about the product's status and my own intent. Degeneration at its worst.

I don't think people's doubts are misplaced but I don't think people should totally dismiss it. I don't expect any Joe Schmoe without any kind of portable tech company to buy one of these prototypes.

This part has been covered pretty thoroughly.

There is no statement saying that they couldn't do that. If this company was approached for a big contract than free samples or loans could be a possibility.

I think it was mostly a response to your other post (Edit; I guess it was lol):

If this enters full rate production costs would come down significantly.

This is basically a low rate production proof of concept which this company is parading around looking for sponsors. There are costs incurred when ever you build one of these prototypes so they are probably charging you for the cost of production as well as some insurance. This is incase if you decide not to invest.

This is not out of the realm of possibility. There's a chance that they are trying to get an independent test authority to validate their claims. It's never too early to look for investors.

I agree that this it's intentionally misleading at best and completely fake at worst.
