Is Fan Speed Change part of the recent PEN?

I received my 6700 4 weeks ago. Thanks to FlexRadio for the great packaging and the speedy delivery. Although I haven't had a great deal of time to use it on air yet, I am very happy with what I have seen so far. The received is sensational!

I have noted that the fans in the unit do not perform as per Tim's post of about a year ago. The 2 larger fans, on each side of the case, only rotate at slow speed almost of the time, as Tim indicated, however instead of the other 2 smaller fans rotating at a constant speed, either 1 or both of them cycle at a more or less constant ratio of 10 seconds slow the 10 seconds fast, on a continuing basis.

As my unit was shipped after June 11th, I am wondering if the PEN email received this morning is the reason for the changed behaviour of the fans, or if I do in fact have a problem. It is not intermittent and happens all the time the rig is switched on. There is not a heat problem in receive as the unit is quite cool to touch.

Has anyone else who has received delivery of a F6700 since June 11th noticed this?

Any suggestions or comments would be appreciated
