Can someone recommend some safe bet solder points for a tiny 12v fan? I picked up some vram heatsinks and was going to place this fan on 'em.

There is no 12V on these TV sticks! It's all 5V.
It might run your 12V fan but doing that means lower RPM and higher current draw than using a real 5V fan.

I understand that its only 5v and the fan will run at lower RPM. Thats how the RPM is controlled anyway. I was looking at getting a different PSU, but also wanted to see how it would run on the 5v 2a PSU first.Originally posted by Finless View Post
Just curious if there was one spot better than another for power.TV Stick: MK808 // Tronsmart T428

An easy place to pull off 5V is from the large USB port board solder points/pins. They are large and easy to solder to. The outer pins are +5 and grnd.

Thanks. Have you noticed another spot for a second antenna on these boards? Having 802.11ac support and 1 antenna doesn't really work.Originally posted by Finless View PostTV Stick: MK808 // Tronsmart T428

I do not recommend to use the same power source to add a fan to your device. First you will generate more noise on the 5v needed for the cpu and memory. second you will stress your psu with a higher demand on current and this will lead to power supply defect. Past 1.2 amps the psu 5v is already starting to collapse you can see that with a scope or multimeter so i recommend a dedicated power supply for your fan. If you remember well there was a company that created an external cooling system for the xbox360 with 3 fans connected to the xbox360. Results: Unstable xbox360 and many damaged power supply.Comment

If you go to the link below you can buy a 5v fan with a usb connector for $9 the best thing is the fan turns at 4000rpm and hopefully less then 20db most 5v fans I have seen on the web run at more then 5000rpm making the fan loud..just plug the fan in a Powered usb hub
