Please excuse the extremely late reply, found this thread hoping for more info on FP3 boards.
Thanks. I'm still looking, so it's definitely not too late.
FP3 is actually a rare and exotic beast -- the embedded-market solder-down AMD R-series socket (Kaveri/Steamroller core based). TDP is in the 17-35W range, far above fanless, but with higher performance.
Indeed for the 35W parts, but 17W is not that much higer than E-350's 18W
, so I don't see why wouldn't it allow fanless operation (especially since't it's soldered down: there's no need to accomodate the possibility of replacing it with a 35W part)?
What you're actually looking for is "FT3b" -- Kabini, Temash, and G-series embedded SoCs. Those are Jaguar core based -- an iteration after the e350. They're available up to 4 cores with higher clock rates and a healthy IPC improvement.
Here's a fanless ASRock board on NewEgg: http://www.newegg.com/Product/Product.a ... -_-Product
But this ASRock system is only rated at 1.5GHz, so on sequential workloads, it's probably not that much faster than my E-350 at 1.6GHz.
