Core i5 6600K Temperatures
Core i5 6600K Temperatures
I'm just starting out with PC building and recently assembled my first computer. I did a small overclock to 4.4 GHz, but the temperatures I've observed are quite high—sometimes reaching 83°C or even higher on the core 1 and 2, while the other cores stay below 76°C. I've also seen people push this CPU to 4.7 or 4.8 GHz, which makes me wonder if that's typical. The room temperature is around 26°C to 28°C. I'm not sure if these readings are safe or if I should lower the clock speed.
If your auto voltage is consistently above 1.3V on average, it's likely trying to adjust for Vdroop, particularly with your ASUS motherboard—though that adds another layer of complexity. For now, reduce the multiplier until auto voltage reaches about 1.3V. Meanwhile, explore overclocking resources and try to gather as much guidance as possible.
If you haven't touched CPU voltage (VCORE) at all, your temps are way too high. Check your cooler installation, and make sure you used the right hardware for LGA115x and not the 2011v3 standoffs. Make sure everything is tightened equally to finger tight, and make sure there's enough thermal paste under the cooler's contact plate.
If you've played with the voltage and have set it to full manual mode, use offset mode to change voltage, or just leave it on auto. It's best not to toy with things when you aren't familiar with the consequences, especially when your hardware isn't cheap/sacrificial.
Abnormally high temps on just a single core indicates IHS functional deficiencies, so I suspect the CPU cooler's mounting method. Set it all back to stock and run the same stress test again. What are your max load temps then?

Quite sure I used the right hardware, I was thinking about removing the 212 Evo cleaning the thermal compound and reapplying, perhaps I used a bit too much. I made some changes just as the guide suggest, moving the voltage from 1.28 to 1.34 but at the end the best result was by leaving the voltage in auto. I'll try stock tomorrow and see how it goes, thank you for the help.
Ahhhh I see.
This guide sounds completely nonsensical, suggesting steps that are clearly wrong. The advice about increasing voltage in tiny increments is really bad, and mentioning 1.3V near the danger zone for modern Intel CPUs is concerning. It's better to stick with auto voltage settings and avoid manual adjustments.

Understood.
This guide sounds really confusing, especially with the advice to gradually increase voltage in tiny steps. Also, 1.3V is getting close to risky levels for most modern Intel CPUs. Going above 1.35V puts it in a dangerous range, and 1.4V without strong cooling is extremely hazardous. For safety, stick to auto mode and avoid manual adjustments.
Hahaha maybe I wasn’t clear about voltage settings. The guide recommended starting at 1.28V and rising up to a stable point, never exceeding 1.34V with air cooling. Right now my auto setting is 1.328V.

I'm currently running at 4.5ghz with 1.35v, using a Noctua nhd14 CPU cooler. At 4.4ghz I'm considering auto voltage, which operates hotter than your own voltage setting, or 1.26v with an LLC at level 5. I also have an Asus motherboard (z170-p). I recommend manual voltage, trying 1.26v at 4.4ghz if issues arise, and using LLC (load line calibration) at level 5 if needed.
