Humax fixes fan noise on its PVRs

We've had complaints on our Forums of certain Humax personal video recorders suffering from excessive fan noise, and now Humax has come up with a fix.
There will be over-the-air software upgrades to minimise fan noise for both the Humax PVR-9150T and PVR-9300T models.
The new Smart Fan Control software will keep fan noise to the minimum, says Humax, by ensuring the fan only switches on if the PVR exceeds a temperature outside of that necessary for safe operation and will switch off after a short period of time.
The upgrades will take place automatically, provided the PVRs are left in standby overnight, on the following dates:
Humax PVR-9300T: November 27th-29th
Humax PVR-9150T: December 5th-8th
All Humax PVRs manufactured since October 2008 already contain the Smart Fan Control software.

When will this upgrade happen again? I got my model (300T) for Christmas but it must have been manufactured ages ago because the fan is a nightmare!
Thanks,
