I haven't heard about that. Do you have a link to the write up? I did
hear about a lot of faulty caps due to a supplier that sold bad batch of
electrolyte to a lot of the cap manufacturers. What formula do you need
for caps? AFIK it's just a matter of buying them for the applicable
voltage. Yes there are formulas for capacitanace to achive the necesssary
filtering but the wrong results there won't cause them to burst.
Unfortunately, I don't have a link handy. The "formula" I was
referring
to is the chemical mix used to actually manufacture the capcitor, not the
one used in choosing it for a circuit.

I've
got a Gigabyte motherboard from the same period with the issue ...
three caps on the board are bulging or split on top. I bought three of
the same model boards at the same time and only one of them have had
that happen.
The cap failure is due to a formulation error. The formua was stolen
from a competeing cap mfr, and they got it just a little bit wrong. There
was a big write up about this when it was first discovered.
