ShadiElwan,
1) The 3 tests I have run (successfully) are OCCT, EVGA OC Scanner, and Intel XTU to get those temperatures. I ran the tests both with stock cooler and then again with a Corsair H60i cooler. I also ran the tests 3 times each. The tests were run for a duration of 5 minutes the first time, then 10 minutes, then 15 minutes. When I get the time, I guess I can run it for longer. I just fall in the category of if the processor can stay stable under torture for 15 minutes, I don't want to keep torturing it for 12 hours more, especially if it is a daily use computer. I could be wrong, but in my experience, usually about 15 minutes is sufficient time to see if a processor will stay stable.
2) VCore was set to auto in BIOS and it was running at 1.15V. It was at stock frequency of 4.0GHz+turbo.
3) Room temperature was 70F which equates to 25C.
4) I actually have 2 cases that I ran these tests in to make sure the new processor was good. One is a Silverstone PS07 with 2 120mm intake fans and 1 120mm exhaust fan (all 3 are Corsair Performance). The other case is a Silverstone GD09 with 3 120mm intake fans (Corsair Quiet) and 2 80mm exhaust fans (Arctic F8). Airflow inside case isn't the best by any means, but it is adequate with good aerodynamics/flow of air. I know some schools of thought think "chaos" is better for cooling, but I've always built computers with good intake-exhaust flow of air through the case.
5) The Silverstone PS07 has a Asus Z97 Maximus VII Gene and the Silverstone GD09 has an Asus Z97-Pro (Wifi/NFC Model). Both motherboards ran the same settings in BIOS and both gave very similar results as far as stock temperatures go. I was able to overclock to far higher temperatures with the Maximus VII, though, with stable OC of 4.896 GHz.
Hope that information helps!
