Hello boogiee90
You don't need to reapply TIM on a new card. Just plug it into the correct PCIE slot on you MB, straight out of the box.
Extra cooling for the CPU would be needed if you wish to OC beyond the capacity of the stock cooler.
First check your power plan in Windows, as default will usually throttle the CPU at idle, unless you tell it not to.
To determine this, run a game or intensive application whilst monitoring with CPUz and you should see core speed changing to match demand. This is basically a power saving feature. You can easily change these values to have your cores at 100%.
