KNC Miner - temperature controller - solves problem with DIE off

[mzahor]

Hi Guys,

I've created MCU controlled temperature regulator.

Controller adjusts fan speed to achieve target (selected) ASIC temperature.

It resolves issue with "DIE off" problem ( some DIEs need higher temperature ).

3 sensors version - 95 EUR [ or BTC eqiv. ] - you can control 3 modules
[ chosen hardware is unable to handle more then 3 sensors + fan control ]

looks like a great solution but there is no guarantee it would fix the problem and the cost is probably 5 times the revenue a resurrected die would make.

It depends on how many DIEs are off.

Good idea but there's nothing scientific yet on bringing back dies. I would be a customer since I do have three boards with a die off but I have to do some tinkering with each one to see if they are fixable

Yes it seems that there are more  different problems with ASIC. One can try heating up ASCI by covering fan or disconnecting it ( ASIC FAN )- if it will lead to start the DIE than controller is solution
