If I see something good, I'll let you know.
No worries, but yes I'm quite sure that it wasn't my case or anything else but the card. CPU temps on a 3.8Ghz 920 were ~65C on a 92mm 3 heatpipe arctic cooling CPU HSF, but of course that just gave you like 4 extra variables to consider so it doesn't tell you much.
Best I can do to let you know the case was cooled properly is the temps from the GPU I temporarily took out to test the new card, the stock cooled 260 c216 ran at low 60s C with ~60% fan speed... airflow was good.
That's my personal experience with it, which you can take or leave because I admit it's only one data point. However, in addition to my own personal experiences though I also looked at a cooler disassembly of it upon it's release, and it's plain to see that the cooler is just not up to the task. The surface area and mass of the piece of metal they asked to dissipate 200+w of heat is about 125% that of a stock intel cooler, it just never even had a chance honestly. So after realizing how bad of a cooler this was and knowing better options existed I started strongly recommending against that cooler, some listened and some didn't because of how aggressively EVGA priced them (even new, they were always clearly cost cut to hit a lower price than other decently cooled cards). Those that bought the card started to quickly grow tired of the heat and noise and started making threads asking for custom aftermarket coolers that fit the 570HD and then I got to mention to them that there were no aftermarket HSFs for it because it's also a custom PCB and I/O so they were stuck with it. I can't say I didn't enjoy reading those threads when I saw some of the same names that ignored me previously
