From time to time I'd get random freezes during load, but it became unbearable recently when ambient temperature started to hit 28C during summer. I've bought one of those nonsense "laptop cooling pad" to see if it makes any difference and boy it does. No freezes ever since, I can video call on web skype for hours (almost 100% freeze reproducer before) with battery charge not falling below 88%. Mind that I'm running stock CPU frequencies by now (stock as in RK3399 stock: 1.8GHz).
Makes me wonder if rk3399 is suitable for passive cooling.
The second major issue -- not enough power for all the peripherals but more power likely means more heat. Personally I'd prefer thicker laptop but with active cooling.
1.8 GHz might be a bit too much for the RK3399, but in my Samsung Chromebook Plus (also with RK3399 and passively cooled) I only noticed a lot of heat when running Rosetta@Home. When playing the Android game Riptide GP, there's hardly any heat.
Once we get more ARM based laptops (and who knows what will happen with RISC-V), it's highly likely passively cooled will become more mainstream.
I think the next Pinebook needs better controller chips, so we get quick charging and proper power to the USB3 port.
That should be easily achievable with a revised power circuitry, so no need for active cooling.
