Very well said powermove. Moreover, every component inside your PC is a heat generator. That's why airflow inside your case matters most and contributes to the useful life of these parts. Therefore, useful life is decreased if you dont have a good airflow.
In the case of capacitors, the solid looking capacitors on your Video Cards is as the same performance with the none solid looking ones we can find here.
Solid looking capacitors are still electrolytic capacitors. The advantage of the solid looking Caps for me is that It doesn't leak ( wa pa ko kakita ug solid caps nga ni leak ) slowly evaporated? It might be , and when the useful life is exhausted, it will just pop. If we are going to replace your VC caps with non solid caps, you dont have to worry when they leak because VCs are attached to your mobo upside down (mostly) not unless you have your mobo laying flat.
I don't completely agree with what is written here:
PiranhaPC - Pure Performance - All Solid Capacitors - for motherboards yes but for video cards, no.
I rely what is written on the tech specifications on the manufacturer like:
Conductive Polymer Aluminum Solid Electrolytic Capacitors
Leaking none solid electrolytic are seldom on Video Cards than on Motherboards. Capacitors that leaks on motherboard are usually the large ones.
