Antminer S9 Fan speed too high!!

[Rockou]

Hi guys How is it going? I have a doubt, las day I saw my first S9 with 15.000rpm and I got scared about that. It normally has about 4.300rpm in both fans... Is it normal? I mean I never saw that before and today It got 33.000rpm... I just turned it off to verify with you about this problem... It does not sound badly, indeed it sounds very well... It's temperatures are normal behind 80 in chip 2 and behind 60 in chip 1... So please help me with this and tell me if this is a problem that should be fixed by warranty or I should stay ok about that...

Not too old, like 5 months old... Right now its running on 30.600rpm... Is it too bad? Should I do something? the temperatures are :

CHIP 1              CHIP2
65                    82
68                    79
62                    81

Guys!! Please help me on it!! I need your comments about this

Unless you're running a turbopump I highly doubt you're getting 33k rpm out of those fans.  That can't be right...

Its fine, the fan is just misreporting its speed. As long as your temps are good you have nothing to worry about.
