Stiffness: Sleeved modular cables

Hello,



I received the Corsair sleeved cables and was wondering if there was a safe way to make them less stiff. I would assume potentially heating them up would be a solution, maybe with a blow dryer on a warm setting so it doesn't overheat the cables, but was wondering if any of you have done this or something else before I go ahead and attempt it.



I'm just trying to make them as untangled and flexible as possible.



Thank you.
