This is happening to me to with h.265 1080p content, a heatsink hasn't made much of a difference unfortunately. I'm going to try keeping the lid of the case off and test again.

No, I don't believe they have.
They have said that cpu throttling may occur when CPU is maxed out for sustained periods.
If that is a problem then a heat sink is recommended.
For some use cases like compiling a large program, the cpu throttling is perfectly acceptable (your laptop almost certainly does the same thing),
but for something like HEVC playback, where the throttling may cause dropped frames, then a heat sink is a sensible option.

I wouldn't say that, since I've added the fan I've overclocked it and 1080p hevc is decoding with no dropped frames and staying around 60degrees. I've only tested a couple of files but it looks really promising
