Here's an update on our tests.
I took the lid off of the NUC (V2) and pointed a fan on it. It's been running for about 48 hours and heat has dissipated from 78C to a stable 62C. That's still a bit on the warm side, but it's an improvement. Our Mediabox 200 V1 run at about 58C. Unfortunately, this hasn't improved the playback of content. Content still lags at times, but I've figured out why.
The NUC (V2) processor might be a new generation of Core i3, but it has almost half the processing power of the V1; 1.8 Ghz versus 3.3Ghz. This definitely shows, and I’m 99% certain this is the reason for our jumpy content playback. Our more graphic intense content is what jumps, while simple content plays back smoothly. However, as soon as we start including multiple zones (weather, rss, live capture) even the simple content begins to stutter. It’s clear that heat is NOT the issue here. The MediaBox 200 V1 has no problems at handling the same campaigns that the NUC (V2) struggles with. It comes down to processing power.
The player has also randomly been restarting itself every now and then. Though I have had this problem on some of our V1's as well though.
Digitalsignage/Mediasignage (what are you guys called these days?) has stated that the V1 is still for purchase. I’m going to continue buying that for as long as I can because I don't want to pay extra for the MediaBox 300. The NUC is a great idea and will probably satisfy setups that run simple content. But even though not everyone will experience over-heating issues, these players still run very hot overall. As a long-term digital signage solution, I don’t think they’re ideal, as the lifespan of the hardware will be severely affected by heat. I’m going to hold out until Intel releases the Core i5 NUC in April. Hopefully by then they will have improved the case design to allow for improved ventilation, and the processing power should be sufficient to match that of the Mediabox 200 V1.
@criley, we're not using the wifi card. There is a fan in the case, but the design is still flawed. There’s not enough ventilation.
