Hello i am wondering whats the purpose of the heat sinks in a power supply. I'm looking to see if i can safely extend the heat sinks by individually adding small copper rods to each of them so heat can be transferred to them. I'm doing this to see if this helps extend my psu life span. Please no one come here and tell me opening a power supply is dangerous etc. I know already. I plan to do this when there's no power in it.
