Asus Probe software acting up?

[mosdef]

I installed the Probe software that came with my A7V and now every so often the program pops up telling me that my fan's (Alpha PEP66) RPMs are suddenly dropping. Is this a common error or is my fan actually screwing up? Thanks.

On occasion, I have seen the same problem, but not on the cpu fan header. Usually it's the case header that does it.
