Just a correction...
Chokes are nothing like capacitors... They are coils of wire which "CHOKE" the current... in effect, they limit the current flow thru the circuit it belongs to.
They do not store any electrical charge whatsoever.

I think they'll be alright. From searching on Google, I found that there are really no results showing people's chokes burning up, just people like me asking about how hot they can get.

A lot of high end boards also don't have any cooling on them.

But, the thinner the wire, the more it heats up as current passes through it.

Yes, they will get hot, but they are just passive coils of wire in a box.
They are not VRMs, which are active devices with one or more transistors in them.
Don't worry.

There are no boards currently on the market that have the chokes heatsinked.

Second time I've corrected that but I'll take your words for it.

Chokes dissipate next to zero power since the resistance of the coils is in the milliohm range. It is most likely picking up heat from something else.

You can argue that they store current. But the more accurate description is that they store energy in a magnetic field.

Well actually no, you couldn't.. simply because you cannot store current
But yes, you are correct.. they store energy in a magnetic field which opposes and "chokes" the flowing current.
