Hey! Sorry for the slow reply, I wrote one up halfway then neglected to actually finish/post it.
The M910q BIOS appears to limit this chip to a PL1 of 40W and a PL2 of 60W, and with those settings it caps out at about 68-70C under a 10-minute looped Cinebench R23 multi-core load. It maintains the full 2.7GHz all-core boost clock, and doesn't thermal throttle (though it does pin the fan at 100%)
In theory this chip should be able to go a bit higher on power draw / all-core boost, but I've not gotten around to removing the post-Plundervolt BIOS locks on power control to try undervolting / overclocking yet. Either way, as-is it's quite a major bump from the i5-6600T!
-- edit after reading the remaining posts in the thread --
@agapitox I suspect the shutdown issue you're seeing is not load-related, but is related to the Intel ME drivers. After I made a few more tweaks to the BIOS (trying to un-hide some of the hidden menus), the system started hard-locking a few minutes after reboot no matter the load level. Disabling AMT/ME in the BIOS, or reverting those tweaks, stops this from happening and my system is totally stable under looping Cinebench R23 tests for >30 minutes. It also doesn't happen under Linux.
Do keep in mind that Prime95 in AVX512/small FFTs mode generates an unrealistic and utterly unreasonable amount of heat, too, and is not remotely representative of any real-world workloads.
All that said, the M910x is definitely a better choice, as it has a
much nicer heatsink and has the PCIe riser slot available.

I only used an M910q because I was able to pick one up for about US$100, and the cheapest M910x/P320 Tiny was almost 3x that price. If you can get the model with the better heatsink for a reasonable price,
definitely do that.
@paf this thread starts out with a somewhat haphazard guide for hacking up the BIOS of an M700, combining it with the BIOS of the M710q/M910q, and patching it with CoffeeTime (a tool which can be found on
the win-raid forums) to make it work; the M700 and M710 are similar enough internally (near identical PCBs) for that to work, and of course you don't need to do the BIOS core replacement if you're starting with an M710/M910.
All the AliExpress sellers are doing when you send them a BIOS dump, is applying the correct set of patches to it in CoffeeTime (and maybe one or two special ones). There's nothing particularly magic about what they do, and the same approach can (and does) work on essentially any motherboard which has Kaby Lake support in the BIOS.
