Heat is the enemy of most electronics including FPGA's. Overclock them 20% and increase their heat output by 50% and you are reducing their life. Properly cooled and stock speeds/specs and they should last more then ten years.

Stock clock for a miner, or stock clock as meant by chip mfg Wink

Yeah, it's quite soon to get reliable figures, but a general direction is possible to calculate.
With enough of them out there, it will be possible to calculate quite early on quite precisely. That's how manufacturers get the MTBF readings - not by testing a huge amount of the product for years upon years.

FPGA usually run much cooler than a GPU. I suppose that give them a longer life expectancy

Remember that it's all solid state things

I don't think there are enough FPGA boards out there to reliably calculate a failure rate. I haven't heard any reports of failing FPGAs so far, and most issues seem to be either software or "heatsink needs to be reseated" kind of things.

I think GPU can happily mine for much more than 3 years if kept at a decent temperature.

I'm trying to figure out what should be the next mining related purchases i do, but one question remains: What is the life expectancy of FPGA based miners?
Has people have them fail?
How long were they running before they failed?
and how many do you got which are still running, and how long has each been running?

That data would help me calculate the annual failure rate, from which one can derive the expected average lifetime

Versus GPUs it seems people expect GPUs to have an average lifetime of 3years, correct me if i'm wrong.
