So I've got a Titan X(M) SC that I upgraded with an EVGA hybrid kit for the 980Ti since the boards are exactly the same. I recently cleaned the card, replaced the thermal compound and reassmbled the card but ever since its been idling and running at the same temperatures as if I didn't have the hybrid kit and just the stock blower cooler. I'm considering double checking by pulling it out again and re-cleaning and reapplying, but if anyone else could give me some options I could try, I'd greatly appreciate it.
 
Thermal compound used is: Prolimatech PK-3 (I also have a spare arctic silver tube for emergencies)

No, I'll have to order some more pads for the memory chips. They might possibly be getting old. I also took another look under the hood and I noticed the tubes from my CPU cooler were brushing upon the center of the radiator fan for the GPU. So with a little bit of work and zip ties, I managed to pull it away a bit and secure it firmly. Upon rebooting, I'm back to a more acceptable idle temperature of 35C. I'll update again after some gaming and new thermal pads.
