You are a pedantic bunch. I changed the post to say fans. My question about whether modifying the miner invalidates the guarantee still stands to be answered.
Does this really need to be asked? Just stop.
Yes it does.
If the heatsink on a hosted miner fails, I guess knc will replace it.
If the heatsink on a miner owned by a guy in the US fails, does he replace it himself and invalidate his guarantee? Which means if the miner entirely stops working 2 days later, he has a piece of garbage on his hands.
So that guy might also like to know how long it takes to be repaired if he has to send it back to Sweden, how long that round trip might take, so he can maintain his guarantee intact.
How is that not a very valid question for many customers?
