Hello,
The artic silver mod did work on earlier models, v1, and v2, but when version 3 came out, they fixed the problem! They added some thermal paste ( artic silver paste ) to 2 needed spots. One on the top board, and another on the bottom board, as well as added thermal pads to some troubled spots as well. If you have a v3, no need to concern yourself with the mod! Just add an ittelite antenna, and have fun!
The phantom 2 mainboards ( all the same by the way, ) originally were designed to have a thermal sensor ( to watch internal heat signature ) and if it exceeded a certain temp, would kick on an internal FAN. but DJI decided it was not needed on the vision or P2 units, so they aborted adding them. But when the plus was introduced, the fan WAS needed, but again NOT? Not sure why.
So
In conclusion,
My thoughts on the best mod for your craft, is as follows.
ADD A FAN!
I've done research on this, and actually created a prototype, for a highly modded p2v, I have. This mod is quite simple, as the plug is already there, to use!
Here is a short video of my modded p2v, with internal blower fan.
I tried several different fans, but the blower model, seems to focus the air directly onto the wifi module, where it is needed the most!
Here are the parts you'll need:
1) crimping tool ( I use ) Engineer PA-09 approx $18 US
2) JST GH pins ( for use n existing connector )
Part # 455-1607-1-Nd ( this is DIGI-key part numbers )
You will need 2 ( 1 for pos, 1 for neg ) but get more, as they are very fragile, and can break easily. They are about $0.35 each US.
3) the blower fan ( this was the best I could find in this size ) a bit pricey, but worth the piece of mind!
Part # 259-1444-Nd
Approx $13 US.
Ok,
Now the plug,
You'll see the FAN port is being used for the wifi module, it is a 3 pin port, but only center port is used ( as a ground ).
Here is a pic.
This will give you power to the fan when you start up the bird. It will run as long as the bird is on.
Now fan placement.
There is a great spot here.
As you can see, the fan will pull fresh air in through this vent, and focus the air straight up, through this cutout
And onto the belly of the wifi module! Again, LIKE IT WAS MEANT TO BE? Lol.
You'll need to silicone the bottom fan frame to phantom shell in the spot stated above. It is not a large flow of air, as these tiny fans don't push too much, but definitely makes a difference, especially when doing computer stuff, with bird on, but blades not ( props are what supplies cooling air around wifi and other internals ) so no props, no airflow! Dangerous combo. I also always use a fan, ( desk fan ) aimed at my bird when doing IMU calibrations, and things like that, where props are not present!
I hope this helps, and congrats on your p2v+ I have 3 and love them.
