If it is like the g10 you will not even know it has a fans. Yes fans in tvs can be bad, I have a Sony SXRD & before I got that everyone said the fan is not the loud or they can not hear it.. Well I could hear it, that tv is in another room & whenever I turn that on, I think I can not beleave that I lived with that sound when watching movies. It is night and day.
The Panasonic tv fans are very quiet, you will really not know there is a fan, if you hear it there is something wrong with the tv or the tv is not getting good ventlation.
I'm about to replace my 5 year old 42" Sony plasma tv. One of my main faults with this device is that the cooling fan noise is distracting. Apparently all plasmas have cooling fans. Anyone out there have experience with the TC-P46G15? Any noticeable fan noise?
