Title: Unified Thermal Core for antminer S5 blades? Post by: Crypto84 on June 26, 2015, 10:26:53 PM I was thinking, if apple could cram all the computing power into a little mac pro case, that thermal core must be really effective. It would probably be a really effective way of cooling for asic blades.
Couple of questions.... 1. does apple have a patent on this? 2. how would one produce this? 3. it it even worth exploring? http://images.anandtech.com/reviews/mac/MacPro2013/thermalcore.jpg Title: Re: Unified Thermal Core for antminer S5 blades?

but a prisma pulled 1400 watts. a triangle setup with 3 s-5 panels = 900 watts maybe 1100 if you push to freq 412. two fans push pull with external controller I guess it could be done.

I thought the Prisma problems were more related to firmware, the exposed capcitors and breakable stuff and no thermal monitoring/shutdown of the chips? In the right environment, some people had no trouble with them. The Tube was a fantastic design/form factor. It took the hashpower, power rating and efficiency of an S2, and crammed it into a very effective and dense package. The fact that the BE200 chips were tough very thermally "tough" probably helped, those things get freaking hot. Anyways, I think 3 hashboards could work with the right amount of airflow, it's about the same wattage as a Tube. Title: Re: Unified Thermal Core for antminer S5 blades?

Post by: padrino on June 27, 2015, 03:20:06 AM Manufacturing that setup is a premium, it's all about maximizing profits and time to market here, not the elegance and market segment of Apple.. Would it work, definitely but I don't see it happening due to the additional costs..

What for? Does anyone think that this will lead to some better S5 cooling? We all know that the main S5 problem is that the heat is removed not from appropriate side of the chip. That is why sticking a little radiators from another side of the PCB is so preferable. Even Bitmain understood this. That is how S5 should look from the first sold unit: https://ip.bitcointalk.org/?u=http://www.pohrani.com/f/3o/oX/Ky40HfS/01.jpg Title: Re: Unified Thermal Core for antminer S5 blades?
