Well, the CM Hyper TX3 EVO does work, but I was wondering if I could improve the temps even more if I went straight to something even more beefy. The weather's getting rather hot lately (thank all-year summer weather in my location), and, well... something just bugs me about the temps even though it's not thermal throttling at any typical use case.
The CPU loves to idle at around 40-45C and can hit 70C easily in a something like IntelBurnTest, though it isn't exactly much better with a real work like a Handbrake encode queue (around 60C).
It probably is also a good idea to also ask about this. What would be a good idle temp delta from room ambient, and load, for a standard-power desktop Haswell i5? Maybe my temps are actually pretty good and I probably shouldn't worry about it?
