I already have a case (ICY BOX IB-RP102). I might invest in a second case if I get problems.
You should have bought a Flirc case.
The case you have is nothing more than a pretty Pi case. The aluminum construction does nothing for the cooling. Adding a heatsink alone will only prolong the inevitable thermal throttling, because the heat still has to be extracted from the case. If you are trying to use a passive heatsink for cooling you are better off not using a case at all. Otherwise you'll need to add a fan to the case, which creates noise and dust problems.
The top and sides of the Flirc case is a single piece of aluminum that makes contact with the SoC (CPU/GPU) and acts as a huge heatsink. It will keep your Pi3 cool without a noisy, dusty fan. The bottom and area near the WiFi/Bluetooth antenna is plastic, so using a Flirc case with a Raspberry Pi3 has a negligible effect on wireless performance. Note that there is an original and Gen2 Flirc case, and the Gen2 is designed for the Raspberry Pi3B (the original was for the PiB+ and Pi2B).
Most of the tiny, cheap heatsinks sold for the Raspberry Pi computers have nothing more than double-sticky tape on them. They don't actually have any thermal interface material, so removing that tape and using a proper thermal adhesive will help, but I don't think those Arctic pads you linked to are adhesive.
