i5 7600k Overclock question
i5 7600k Overclock question
Last night I experimented a lot with my overclocking setup. I successfully reached a stable 4.9ghz for my 7600k in Prime95 and Aida64. In Aida without FPU stress, temperatures averaged around 60 degrees, with some peaks up to 70. When FPU is active, it drops to about 65 degrees, occasionally reaching 73. Small FFTs in Prime95 can push it to 85 max briefly before dropping back to the high 60s. I believe this test is more demanding than typical usage. I'm running at 1.275 volts with occasional spikes up to 1.3. Should I consider upgrading my CPU cooler?

@JackNaylorPE those temperatures and voltages were checked with HWinfo. I also ran the same tests using HWinfo closed and real temperature measurement. The real temp matches HWinfo. Yes, it was core temps. I was initially doubtful about the outcomes. However, I've used various monitoring tools separately. Most of them agree. That's why I'm sharing this here.
These temperatures appear quite low for the Hyper 212... Is it correct that you're checking core temperatures rather than CPU package temps?

Those temperatures and voltages were recorded with HWinfo. I also ran the same tests using HWinfo closed and real temperature measurement. The real temperature matched HWinfo. It was core temperatures that mattered. I was initially doubtful about the outcomes. However, I've used various monitoring tools separately. Most of them gave similar results. That's why I'm sharing this here.

JackNaylorPE shares a useful comparison regarding synthetic stress tests. He mentions using OCCT-Small for 30 minutes to check temperatures and OCCT-Large for 3 hours to verify stability. However, he doesn’t support the vcore/cooler chart. With an EVO 212, I don’t face problems running at 1.3Vcore. I plan to load OCCT and test OCCT-Small for half an hour, observing temperatures. If they stay below 80°C, I’ll run OCCT-Large for three hours to confirm stability.
The chart originated from the Asus website... I incorporated some categories in the middle. It was built for extreme conditions. In various climates, summer temperatures can be 10 to 15°C higher than winter temps, with significant changes in ambient conditions affecting CPU temperatures based on the temperature difference. For example, a 75°C CPU in a 68°F room would reach 85°C at 86°F, and 93°C at 100°F. OCCT is a synthetic test, essentially a collection of other synthetic tests. You can pass OCCT, Prime95, AIDA64 without issue, but may fail under a real-world multitasking benchmark using actual applications.
JackNaylorPE shared his thoughts on the chart from Asus's website, noting it was adjusted for extreme conditions. He explained how temperatures can vary significantly between seasons and climates, affecting CPU performance based on temperature differences. He mentioned that a 75°C CPU in a 68°F room would reach around 85°C at 86°F, and even higher at 100°F. He agreed with the idea but felt the original poster would be satisfied with a cooler setup using a 1.3Vcore, suggesting liquid cooling might not be necessary for his needs.
People often prefer sleeping on a Hyper 212x cooler. At the end of the day, they excel at overclocking with a (push/pull) setup. The reason for their dislike remains unclear to me. The Hyper 212 is considered a "great cooler for the money." However, the final three words usually get omitted from the description. Without those three words, the statement doesn't fully capture the point. A "great cooler" would be one that significantly lowers CPU temperatures during overclocking. Your overclock performance will be constrained by either the temperature limit you set, the voltage you choose, or stability, which relies on both. A "great cooler" removes the need to worry about those factors. The Hyper 212 can provide a solid overclock but won't reach 5.1 GHz at 1.4 volts.
I agree somewhat, but the key difference lies in our approaches. I didn’t include the last three words because they’re essential for clarity. I believe a "great cooler" would eliminate the need to consider temperature limits and voltage settings. My concern is that if this is the case, what I’ve discovered is that I can run AIDA 64, Prime P95, OCCT, and maintain stability for 24 hours, yet fail when using real-world applications.
JackNaylorPE :
No argument there ... my issue if this however ... what I have found is that i can do AIDA 64, Prime P95, OCCT and pass 24 hour stable ... and then fail running real world applications.
All good info. And as you know what his particular system will do will be dependent on his piece of silicon.
The OP’s original question was if he should upgrade his cooler. As has been pointed out Prime95 produces unrealistic high temps and for me AIDA64 has produced temps lower then I see with real world applications. If I were him, I would run OCCT-Small just to see what I get for temps. If his temps are staying below 80C at 4.9GHz with a Vcore of 1.275 (or 1.3, still not sure if he is in auto or manual) then I would say no he doesn’t need to upgrade his cooler (assuming he is stable at these settings).
