I got the EVGA GTX 980 SC, and an EK GPU block (Thermosphere) I never used. I was considering to use the Thermosphere and some modded Enzo heatsinks for the VRM part, but leave the memorychips free as its not possible to do anything with the 3 chips under the Thermospere cooling block. I got a pretty good static airflow through my chassis. Anyone tried a thermosphere on a GTX 980? Do I need memory cooling?
