got my 5 antminers from batch 4 and all works great on p2pool but showing strange fanspeed 5000-9000RPM

ofc its a bug becouse it would be jumbojet noise. I flashed one with same firmware from 21 july (downlaoded from bitmaintech site) and fanspeeds didnt change ;p so its the same firmware not as someone above said that its diferent ;p
Dang 5000-9000 rpm would be cointerra loud!
and even at those speeds the cointerra would be pushing 90-120C (cointerra tech says 120c is ok

)even with AC blowing directly on them. Soo glad I got rid of those abominations. The Bitmain are sooo much better, cost less, cost less to run and run cooler.
i think it must be some kind of error because all of mine are getting crazy fan speeds too.
i even had one reach as high as 14000 .. they do not sound like jet engines so must be an error.
btw overclocking:

225 -1x 440g/hs
250 stable 495g/hs
250 stable 510g/hs
250 stable 495g/hs
237 stable 475g/hs
250 stable 480g/hs
250 stable 500g/hs
250 stable 500g/hs
i have one asic number 10 hashing with one x .. i might pull that one and open up heat sinks again and look.
i think the other one at 237 could reach 250. i probably test again soon. the last one that is 0's is on my
workbench opened up waiting on my 30g of thermal paste to arrive. i am working on additional thermal
paste tests on that one when the thermal paste arrives.
