Accessories that reduce overheating
« on: June 17, 2014, 03:36:30 PM »
Hey guys,

I have been hypothesizing about ways to reduce overheating since summer is here and I am shooting outside on a lot of hot days.

I was thinking about the camera's internal voltage regulation. I'm sure that it has several DC-DC converters that regulate the incoming 8.4v (from battery) to the needed 5v, 3.3v for the various components inside. I was wondering if feeding the camera an externally regulated 7.2v might reduce some of the heat generated by the internal DC-DC converters.  What do you think? I'm not so sure using a battery grip makes as much of a difference as using an external powering solution that regulates the voltage.

I wrote an article about some other techniques I have used to reduce heat here:

and I also wrote an article about building a shoulder mount that uses externally regulated Anton Bauer batteries to power the camera here:

I'm not trying to spam the forum with my blog posts, I'm truly looking for feedback about reducing heat with externally regulated power. I just thought I would share the info since it's relevant. Just to show that I'm not biased, here is a great  article not written by me that pertains to this subject:

I'll have a 7.4v battery setup soon so i'll report how it effects my notorious 550d and 50ds.

Both like to get too hot and I hadn't considered that external power could help.

The battery itself getting hot contributes in the 550d certainly, using a battery grip helps a little.

Astrophotographers have been dealing with this issue for ages. There are lots of different accessories that are used. Here's a commercial one that will get you 43F below ambient:

Of course there are lots of different custom and DIY solutions as well (that are a lot cheaper), just search some astrophotography forums such as cloudy nights or google 'peltier cooler'
