Caps that can tolerate higher temperature is a good thing to try, but so is
cutting down on the heat produced in the first place.  These kind of caps do
take more to manufacture, but if you have high ripple current it's either
that or the problems you see.  This is why the Panasonic FK series
(specifically designed for low ESR and high ripple current) are physically
bigger and more expensive than those with otherwise the same spec.  There is
no free lunch.  Many of the other series are meant for other applications,
and if you look carefully they don't even have a ripple current spec.  This
is common for "computer grade" caps, for example.
