How often does this need to be applied? is it just when you install the aftermarket heat sink or like ever year ever 6 months?

Also iv read some things online of people applying it to there GPU's does it need to be put on GPU's???

1. It really depends of the quality of the thermal paste. Some thermal pastes can last for ages, some a year or two. You do need to reapply thermal paste when installing a new cooler, yes.

2. It is not needed. However I made a video of doing it, and as you can see the applied thermal paste by the manufacturer looks really dry and was splattered all over the place. So reapplying thermal paste did help on the temperatures. It is not needed, but the enthusiast will definitly consider applying new thermal paste.

It needs to be applies anywhere that a heatsink or cooling surface needs tight contact to a heat generating surface, like a GPU and CPU, mostly you only need to worry about a CPU.
It will need to be fully cleaned of the cooler and/or CPU after cooler removal. Many aftermarket coolers come with it pre-applied though.
Unless a GPU is getting abnormally high temps it is not advised to remove the cooler and re-apply thermal past as the manufacturer has already done so.

Only once, unless there are temperature problems. Same for gpu. And of course every time you change a heatsink.

Correct - GPUs come as a complete finished - heat sink included. I've had my cpu heat sink installed for 4 years - no temp problems.
