Panasonic SD707/TM700/HS700 - fan not masking tape!
Frage von DocD: August 2010
Miscellaneous forums users have reported that you mask off the fan for noise reduction of Panasonic camcorder. I measure straight with my HDC-SD300 has (synonymous of a fan), the duration of third-Batteries. As a small side effect I noticed the enormous heat generated during continuous operation:
After half an hour of continuous recording, although the case is only slightly warm. On the PCB we can already measure about 50 degrees. And when you press his fingers against the slightly recessed metal parts of the video - or HDMI connectors, you will burn almost! My infrared thermometer measures s.diesen parts up to 64.5 degrees. If the sockets already reach this temperature, the circuits on the board will probably have around 90 degrees. The fan is so far from useless knick-knacks.
It might incidentally synonymous suffer the noise behavior when the camcorder is too hot: Apparently, the fan cools so the 3 CMOS sensors - which has brought a member of the forums Panasonic support in experience. Of cameras is known to be more noise, the hotter the sensor is - after some time Live View is the noise more.

This was perhaps synonymous anyone even halfway controlling his mind, expect synonymous ... I still have no camera at issue (for Mac / Win threads already) Vollpfosten so many experienced, as in the 7 Series Fan ...
Antwort von JMS Productions:
I've synonymous all the time in various threads here and each time was made known to you laughed at or ignored. Not only is because the fan in me an external Micro in action;) How can you only come up with the idea, to cover the fan ...
Antwort von WoWu:
The data for the noise are the manufacturers based on a uniform 23 ° C. Each with 7 ° increase doubles the noise values.

Elsewhere, I have already referred to the principal once a fallacy only moderately heated plastic housing. Just the opposite is the case: the case of metal housings, which do not hinder the heat dissipation so, should the user the right way can actually see very quickly what is going on really internal.
