The main advantage to me is that they raise the laptop above the working surface and allow good airflow.

I don't rate the USB ones, as they are using power from the machine and that generates heat. It also drains the battery.

Increasing the RAM doesn't generate heat, only using it does.

Your best move that you have suggested is to replace the HDD with SDD.

Using an external drive as opposed to the hotswap would also reduce power demand and hence heat? Otherwise look at SSD, although I haven't seen 1TB yet, and it is expensive.
the only problem im having with externals is they are designed soley for backup they arnt geared towards everyday use ive had 3 fail on me that way , thats why i was looking at getting a 1 tb magnetic for the hot swap port and a 200gb ssd for os drive just wanted to clarify i think i was half asleep before again thank you everyone so much for your help just wanted to clarify and share knowledge
