I have a NUC5PPYH with the Brasswell Pentium N3700 processor. I put it in Akasa fanless case.

I have a habit of feeling it to see if the fanless case is doing the job.

While running LE 7.0, when idle, it is barely above cold. After watching a 2 hour movie just warm.

Running build 518,

It gets very warm while idle and borderline hot while viewing a movie.

When debug mode is on, and idle, it reports the CPU as very busy, of 50% average of all cores.

I surmise that there are still race conditions in the Kernel when running on Brasswell.

Nobody can help you without a Debug Log. But yeah, if you want speculations. Here is another one: Stop intrusive scripts while watching videos :-)
