Question for the electricially inclined folks who are following this thread:
I was consdering what to do about the "jet engine" fans on the miners.
I thought perhaps I could clip the "red" wire (not both) on the fan...and in-line one of these male/female connectors: https://www.radioshack.com/product/index.jsp?productId=2104016
This way I can easily enable/disable the fan and not have to put connectors on both black & red wires on these...but by simply disconnecting the connector or reconnecting it as needed.
Is this a good idea? Assuming I'm only going to ever scrypt mine...but I think this approach could help me to reconnect the fans quickly should I be inclined to use the SHA256 chips for mining some magic new coin which may pop up and be worth it...very doubtful but...who knows?
Thoughts?
As long as either end of the + doesn't short out on the body of the miner, you should be fine.
I'd do the ground wire (black), myself because it's negative and if it does short to the body, nothing bad should happen. If the fan end of the black wire shorts out on the body, the fan should simply run.
As usual,

Thanks for the response Wolfey2014...
I'll try this out on 1 miner using the black wire instead. The connectors are insulated so I don't think it should be an issue of shorting out...that is unless I do a crap job on crimping the wires into the terminals...I'll also put a bit of electrical tape across the open ends of the terminals just in case so it should be fine.
Let's see how this goes...wish me luck!
You are welcome.
You may be wasting your time because the wire between the fan and the PCB - first - isn't exposed to the outside world as it's snugged up inside of the pod fins - second - the wires are not long enough to add plugs to and have enough to do any crimping on much less plugging of.
I simply disassembled mine (4 screws for the fan and 4 screws for the heat sink) and de-soldered the fan wired from the PCB. They are completely removed and there's just a nice little golden pod sitting there now with no fans on it. Make sure you put a little bit of torque on the screws when you tighten them back up. I found several of mine were lose. On one of them, you could tell that the heat sink wan't snugged up against 2 of the ASIC chips which would allow them to fail due to overheating if I were mining SHA with them. Gridseed definitely needs to improve their quality control!
Also, I left the fan mounting bracket on each pod and used the 4 screws that held the fan in place to act as a stand off so there is some room for air to circulate from the bottom up through the fins and out the top via 'convective' air flow.
So if they get warmer than room temp, they'll self cool to some degree. Certainly enough to prevent any overheating problems while running Scrypt.
It's too bad that the engineers didn't incorporate temperature sensors to not only monitor the unit but also to act as overheating protection.
I'm running mine now with no fans at all. OH! THE PEACEFUL SOUND OF NO FANS!
The only fan running now is the one in my 25 Amp Radio Shack switch mode power supply which is very quiet. I'm cool with that.
As usual, do any of this stuff at your own risk!Wolfey2014
