I think I might do your mod, how has it been working so far after the mod? Thanks! :)

It's been working great. I don't leave the unit on all the time, but I do use it 3-4 hours a day and it hasn't overheated once yet. From about 7ft away and the tv on, I can't even hear the fan anymore. I'm really happy with it.

Hey guys, just a heads up, but I was messing around in the settings and discovered how to enable hdmi cec. All you have to do is turn Easylink on from the settings menu and reboot. As long as your tv it's compatible, you can control the gamestick with your tv remote. Hope this help.

Is there something you need to do to turn on the fan? Pretty sure mine isn't working or is broke... :-/ 

You don't have to do anything on an unmodified dock.  The fan should turn on by itself once the sensor detects enough heat. 


A quick way to check without opening the dock is to turn on the dock without the gamestick inserted. Refer to the picture from my tutorial to locate the thermalcouple (sensor) and use a hair dryer to heat up that area (don't melt the plastic, just hot to the touch).  If everything is ok, the fan will come on automatically.


If that doesn't work, I can help you troubleshoot the exact problem, but it will involve opening the dock and probing voltages.

ok, but IMO a shitty fan in low speed would not do much,  I think if I was to mod it I would just change the fan.

But here is the deal... I measured the voltage signal of temperature sensor of the dock before and after the mod. The voltage of the temp sensor drops as temperature goes up.


Before mod: Temp sensor voltage drops below 2.5V => fan turns on

After mod: Temp sensor voltage never dips below 2.8V => fan signal never activates


As another data point, I used a hair dryer to artificially heat the gamestick so the voltage dropped down to 2V and the modded fan cooled it enough to bring the voltage back to 2.8V after a few minutes. 


The problem with the stock cooling solution is that it only comes on after it hits a certain temperature threshold.  When it does come on, it is full blast and stays on for 2 minutes.  My solution is to keep the fan on as long as the dock is powered up, but have the fan at a constant low speed.  This way, the heat doesn't get a chance to build up as the constant airflow is regulating the temperature.


As I mentioned earlier, I couldn't find my own temperature sensor, so I don't have data points in terms of degrees, but I did monitor the internal temperature sensor built into the dock.  I don't think the fan itself is bad, it's the way the cooling system is implemented that is flawed.

Thanks for the tutorial :)  If I had a dock I would definitely give it a try.

Quick question: looking at the pics, what exactly is the fan doing?  Is it blowing air into the side of the GameStick or sucking out hot air from it?

Just curious.

The fan blows the air into the side of the stick with the help a plastic shroud.  (I'm using my paint skills to illustrate the flow)
