Okay, I know at a glace this could come across as a stupid topic but I would really appreciate it if an articulate discussion came of this...
Cryptocurrency mining hardware is very expensive, and we should look after our rigs as best we can. After all, the build up of dust reduces air flow, raises temperatures, kills blades/miners.
However in my (limited) experience, the components that get killed on the boards aren't often the mining chips as you may think, but the often disregarded power regulating components. Mosfets, capacitors etc. Without this becoming a rant at some manufacturers that under-power their boards, over-stress the power supply circuitry, so it runs fast until it out lives the warranty. Some of us are doing this at a hobby level and don't have the high turnover of constantly getting the newest model of ASIC. We need to make our units last.
So my next point is regarding temperature. For one, people refer to overclocking ASICs and state the temperature that their interface is telling them the unit is at. Often this is wildly inaccurate, giving a surface temp of a PCB or once again measuring the mining chips and neglecting the Mosfets. Yes, when you overclock a mining chip it may raise in temp from 60 to 75, and you'd think with it's upper limit of 125 that'd be fine. But what's the temp of the Mosfets, capacitors etc we're stressing driving this equipment? As I said before it's not often the mining chip goes pop.
So my last point and the punchline really. The power supply components are often smaller than the mining chips in terms of surface area. They are also of unequal heights and this makes it very impractical to fit heatsinks. The designer places them in the airflow as best they can, but as I mentioned, with the enclosure around them this can be partly obstructed especially over time if not maintained. Is the answer not fluid cooled systems, immersion I mean, that give even heat exchange across every component? No matter how small?
I get that could be a logistical nightmare to ship. But I've seen very few hobbyists adapt their miners this way too. Am I missing something? Or if it ain't broken don't fix it?
But lets be honest on a technical level it would be no more complex than assembling a simple frame and dropping it in a fishtank of mineral oil. (A kind of gross simplification).
What about people that want to mine with an S7/S9 at home but can't put up with the noise?
A few thoughts.
Some interesting examples on youtube.
nice to hear this topic again..
at the beginning i was fascinated about this kind of solution...
With the same power consumption you can push S9 frequency to the limit...
but then i have stopped all my project when i'm not been able to find a valid Novec fluid alternative...
here you can find a lot of data avout this fluids data:http://www.3m.com/3M/en_US/novec/products/product-catalog/?N=8708160&rt=r3
last time i have checked the price, was at 125eur for 500ml and 215eur for 1Lt..
too much expensive...
