Cheap is relative, based on your power costs.  V9's only make sense right now if your power is hovering around "free."

do we know what exactly is a hw error ? it makes no sence to me since only 1 board seems to get em out of 3

I believe most of my hw errors are from, temperature/fan timing, and network delays. I also see 1 board more than others
sometimes. In cgminer, and awesome miner, it shows independent temps per board , and if 1of them takes longer than
the set time to "warm up" in operating range, it throws an error. Vise, versa, if it takes too long to cool down when it runs
too hot.

These are most of the errors I've dealt with. I expect them to be better, once the miners are in my basement. They are
out in the ole 30°f garage until then.

I have a s9 fan that has some vibration and is getting hot. If I purchase from bitmain by the time I get a replacement with shipping the fan will be approx $27us each. I see a few options on ebay but I'm wondering about the cfm. Can anyone recommend a vendor for replacement fans in the US?

Depends on your location, but...
This is the closest unit I've been able to find that ships soon/reasonable. What I've found on eBay takes a slow boat to the States.  Sad

Edit: This compares to the Delta QRF1212GHE that Bitmain sells as a replacement.

An afterthought: any 4-pin 120mm fan will work, but it NEEDS to put out at least 240cfm to match the original, which will turn 6000 rpm. You may have to swap the tach and pwm pins on your new one.

...
Network has nothing to do with hardware errors.
A HW error is internal to the miner - somewhere in the process of passing data from the chips back to bmminer, a checksum or counter is wrong.
Note also that Bitmain miners hide a lot of the hardware errors Tongue

Um ... that's facts I've stated there Smiley

I've posted about the issues with their code and also put in a public git updates to fix their code years ago - S1, S2, S3.
They do seem to have at least finally stopped hiding stale shares with the S9 ... since that also meant throwing away possible blocks Tongue

As for which hash board gets the most errors, well you'd need to take a much larger sample to be sure that there's a pattern there.
Remember there's probably at least 10EH of S9s out there ... i.e. probably at least 0.75 million of them

Ugh... ~10% increase.

Isn't there a possibility of the difficulty lowering if a lot of these New Year's Resolution miners give up already?

Not likely - they'd sell their miners to someone else who'd use them.
... and if they didn't sell them, but just switched them off, there'd have to be more of them switched off, than new miners coming online.
