Not having a built in fan to take away the heat from my Yoga 2 11 really causes me a lot of headaches. I can't use it outside on any kind of warm day. Browsing the Internet without using a cooling pad is hit and miss and everytime I take it off the laptop off charge it quickly heats up to the point it freezes.
Severe headache everyday from this laptop and it could all be remedied with a built in fan.
Do all fanless Yogas suffer from these issues?

Passive cooling assigned to the CPU as built for most ultrabooks, due to the compact and slim designs heat may be a factor to consider (less space inside to move the air).
Common to this generation of Yoga at that time were concerns about throttling performance as seen here.
The workaround on disabling the DPTF in the BIOS is not recommended but did help some users as they sacrifice the feature for better performance.
DPTF regulates the CPU so that heat is controlled. Here you can also check if the change in setting would help.
Aside from disabling services like YMC (controls flipping the screen in modes but also can increase CPU activity) and decreasing active processes through clean boot, disabling synch service like google drive/ one drive and addon browsers can help.
If you are definite with the heat and absence of active cooling in the design, aside from cooling pads at the bottom then you can also try this trick from this discussion. Else, drilling small vent holes strategic to the bottom cover can be a bit aggressive (open to external dangers of dust and liquids) and less cosmetic since there is no space inside to add an active fan system.
Hope this helps answer your query.

The issue with DPTF is that when you're switching the laptop around into Tablet mode or Laptop mode the processor gets throttled too hard.
That isn't the issue I'm having.
Just during general use of my Yoga 2 11' overheats and throttles severely. Once the temp hits about 62F then the laptop will slow itself down until it locks up. Once the laptop cools down a little then it will be speed back up.
I honestly can't even use my laptop because of the overheating and CPU throttling. Having no active cooling really hampers my Yoga 2 greatly.
This heat problem happens in Linux as well (not as severely) and also happens on clean installs of Windows.
The only solutions I can come up with re-thermal pasting the CPU & installing active cooling to suck the heat out. The CPU just runs too hot to not have a active cooling.

If the above steps and workarounds did not work (if it was at tried) then DIY changes surely can be done as mentioned though hardware modifications. this may be a factor to balance performance against cosmetics.

No. My fanless Yoga 900s runs much cooler at ~30C than most of my ThinkPads. Granted that's just a sample of one.

You don't ever have over heating problems with your 900s when using it outside or in a non-air conditioned environment?
Right now my Yoga 2 is at 55C and it is on a cooling pad with just Chrome and TightVNC opened.

Nope. I find that to be one of its "coolest" features.
