Yes, those temperatures are completely normal in IBT, which is one of the hottest programs out there. Based on what I just learned yesterday from an intel heat guru, use prime95 v26.6 small fft test to get a consistent temperature. These are all synthetic tests though, so real world use will generate much less heat. I personally use prime95 v26.6 small fft to check temps, use 50 passes of IBT very high (someone on here told me its unsafe, but online, I see ppl running 250+ passes at maximum on IBT, with no issues), 2 hours of Aida64 (which I added recently since I just figured out they have a 30 day demo), and then 15 passes of memtest86. For the IBT, prime, and Aida, I have furmark running in the background with my GPU overclock to ensure stability when both are under load. No idea if thats the proper way to do it, but its working for me so far. (Disclaimer, I'm not a pro overclocker by any means, so take my advice with a grain of salt)
