Well I finally got my ball bearing fans in for the stock replacements.
They work well but they are extremely loud compared to the stock sleeve fan.
They are the same type/brand as the stock fan, just ball bearing, direct replacement.
You probably bought one that is really high RPM...these fans can go up to 15k RPM. You only need about 7-10k RPM to properly cool these. Stock fans run around 9-11k.
Yeah I got the 10k ones, couldn't find lower.
I tried a 15k and those were seriously loud.
On a side note, I have zero explanation as to why -- I threw the Asic I thought that was dead on a different hub after not using it for a few days and its been working for like a week now. I'm now wondering if the 100% HW error and extremely low hashrate rate was being caused by something else, perhaps the port on the hub I was using.
Can you share with us the model and brand name of the fan..
Thx.
