M1X has a heat pipe.

Re: M1X has a heat pipe.

Anyone know if this heat pipe is just for the Dual TruePic VIII Image Processors or will it reduce the sensor temperature as well. I am thinking of possible use for long exposure photography where lower sensor temperatures has a significant beneficial effect of lower thermal / dark current noise. Dedicated astrophotography cameras have thermoelectrical cooling (TEC) cools down to -45C below ambient but requires external power supply.

I look forward to seeing milkyway images produced with the E-M1X.

The sensor has to float for the IBIS to work so I don't know how much would be for the sensor cooling.
Heat dissipation construction


1. Heat pipe
The heat dissipation construction of the E-M1X is achieved via the use of a heat pipe to dissipate heat generated whilst shooting. In particular this feature limits issues caused by rising temperatures from continuous shooting or shooting videos in hot weather.

Re: M1X has a heat pipe.

The review above claims that the heat pipe keeps the sensor cool

"An integrated 'heat pipe' helps keep the sensor cool while shooting bursts or videos for a long period of time."

I think Ross makes an interesting point about the sensor having to float. I would have thought however that when IBIS is turned off the sensor would rest on some form of solid block allowing it to benefit from some cooling. This seems like a question to ask the Olympus designers.

Yes, I have been wondering about this as well. I suppose it could float in a heat-conducting magnetic fluid, but Im sure theyd say that if it did. A fan for forced air cooling?

Perhaps the Haynes Camera Repair Manual for the EMIX might explain.

I wasn't aware Haynes had spread the net, but apparently so:

Re: M1X has a heat pipe.

All the photos I've seen to date suggest that the heat pipe is for the processors, though I guess removing any heat from near the sensor must help a little, but it appears to be the other side of a casting to the sensor...
