Interesting, my pc is about the same. I've a cm elite 370 with only stock fan and gpu the same but from club3d overclocked edition.
my idle is 30 for cpu and about 36 gpu but it underclocks to 300mhz. does yours to go to 300 when not gaming? I've not seen by gpu past 63 but It can probably go higher. I've used kombuster. The max I've seen my cpu is at 57 with 100% load in handbreak.
