Heatpipes, most likely. Like in Sony's Z4/Z5 (Z3 too?)Liquid cooling for the new Lumias?

Yes. It's a bad physical design implementation.Does anybody know why this SOC is having so many heat issues?
Wonder what happened... Qualcomm isn't exactly a slouch at making chips.
That guy was complaining about sourcing/using ARM's architecture instead of in-house, which is totally besides the point and really makes me doubt he has any clue of the issues.I saw a comment from someone who claimed to be a Qualcomm employee saying that the work was more outsourced than usual.

Qualcomm has been using ARM's cores for a very long time in the low and mid-range, so heat issues with the S615 are not really explained by "inexperience". They don't use ARM macros.
No but you worded it exactly like one claimed employee was complaining about stuff. Might be two different people.That's not what I remember, are you sure we're talking about the same post?
I don't think the size of the IP has any impact on the quality of the physical design, maybe a bigger core takes more time but that's about it. Again, I can be wrong here but that's what I understand from researching the matter over the last year or so.I'm not convinced experience with the lower end cores directly translates to the higher end ones which are significantly larger and more complex. I could see this still being a blindspot for them.
Yes, pretty certain. Users of ARM's hard macros for seem to be limited to Chinese vendors. Any of the big vendors (QC, Samsung, MediaTek) have their own design teams.Do you have a source that they didn't use hard macros for these parts?

That's old news though, arstechnica did some article half a year ago showing the same thing: http://arstechnica.com/gadgets/2015/04/in-depth-with-the-snapdragon-810s-heat-problems/Was reading the anandtech nexus 5x review. Never knew the 808/810 could throttle so bad as to shutdown the A57s.
Kinda cool that ultrasonic finger print works thru aluminum.
