Hi Everyone, I have a Duo2 and it is experience freezing sometime. So I am suspecting a heat problem and would like to install an internal fan. I have found some connecting pins on the main board and would like to know which of this pin I can use for fan connection (attached photos). And how many pins should the fan have that I should get? Thank you

My Duo2 never had a fan nor did it ever need on & I kept it in a TV unit behind a glass door 24/7. As the PSU is also external do not believe adding a fan to it would serve any purpose at all.

Hi Guys, thank you for your reply.

I must admit of not looking properly and miss out seeing the vertical fan. Most properly I was feeling sad and miserable about the freezing as it had disrupted my timer recorded shows. It freezes during playback, sometime with timer recordings running and sometime there isn’t. I was thinking installing a larger fan to eliminate this abnormality. Any suggestions are most welcome. Thank you

Original Duo2 does not have internal PSU nor a fan.
