I recently purchased a used 980 ti hybrid on the used market. Is it advisable to remove the cooler and apply a fresh layer of thermal paste?

Thanks bob.

Oh by the way, wanted to tell you if you use Conductonaut to be careful with it..It's extremely electrically conductive being, well, liquid metal..If you roll with that it's a good idea to paint the area surrounding the chip with a couple coats of clear fingernail polish for insulation just in case, like I did, there's circuits there..The stuff is beyond awesome though..Kryonaut is good stuff too, conventional thermal paste.
