Default Re: GPU Caps Out of Spec?

Polymer caps don't have a liquid electrolyte that can evaporate over time. BTW, the dielectric in an electrolytic or polymer cap is not the electrolyte or the polymer. The dielectric is a layer of aluminum oxide on the surface of the anode foil. The electrolyte-soaked paper or polymer is a conformal conductor between the cathode foil and the aluminum oxide surface.

Some ultra-low impedance electrolytics have had problems with the electrolyte attacking the aluminum oxide layer, but I've not heard of problems with the polymer affecting the aluminum oxide layer.
