i7 6700K air cooled with 4.8 GHz temperatures at 85°C
Hi,
I was able to successfully overclock my new i7 6700K to 4.8 Ghz using a CoolerMaster V8 Air Cooler and CoolerMaster MasterGel Maker Nano thermal paste. The core voltage is set at 1,33V under full CPU load, and the benchmarks are performing well with stable operation. However, I’m curious about the temperatures—reaching up to 90°C and averaging around 85°C during full load seems a bit high.
System Specs:
Intel Core i7 6700K @ 4.8 Ghz
ASUS Z170-Deluxe
MSI GTX 970 4G @ 1440Mhz Core
16GB G.Skill TridentZ 3200 C15 @ 3333Mhz (CL15,15,15,35)
XFX Black Edition XPS-850W-BES Power Supply
Hello!
That's quite high, well above 75°C. Running temperatures this high can significantly reduce the lifespan of your CPU, so aim to keep it under 75°C during heavy use.
the difference between 4.0 ghz and 4.8 ghz isn't significant (similar to walking a few meters). it's not worth the effort of upgrading to 4.8 just for minor gains like increasing power use or heat. if performance really matters, focus on the number of cores in your CPU. but if you still prefer 4.8, consider liquid cooling instead of air cooling.
Just to confirm, the 6700K turbo speed is indeed 4.2 GHz, correct? So comparing it to 4.8 GHz, would that mean a difference of 0.6 GHz? I want to know if a tough game would push the CPU to run at 4.2 GHz instead of 4.8 GHz.
The stock speed is 4.0Ghz and turbo speed is 4.2Ghz. When a program or game demands more performance, the stock CPU increases to the turbo clock. In my overclocked setup it consistently runs at 4.8Ghz with average idle temperatures around 33°C. During games I experience temperatures between 50 and 65°C, which are noted only in pure CPU benchmarks, burn-in tests, or when running without other loads.
85 under something similar to prime95 is okay. You won't encounter that in everyday situations, such as in a video game.
In a crucial part of air cooling, the air movement inside the case is essential; you need excellent airflow and numerous fans.
