i7 6700K Air Cooled at 4,8 Ghz temperatures at 85°C

FireRoMe · Sep 29, 2016

Hi,
I managed to succesfull overclock my new i7 6700K to 4.8 Ghz with a CoolerMaster V8 Air Cooler and CoolerMaster MasterGel Maker Nano thermal paste. Core Voltage is 1,33V with full CPU load. Benchmarks are looking well and the system runs stable. But I wonder if the temperatures are a bit high with up to 90°C and round about 85°C average under full load.

System Specs are:
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!

Wow that's high, too high in my opinion, nothing over 75C

If you run your temps up too high it will shorten the life of your CPU by a tonne so try to stay below 75C under load if you can

difference in 4.0 ghz n 4.8 ghz is not much (like walking 5m or 9m). i mean, its not that worth by oc'ing to 4.8 and increasing the power consumption and temp of the cpu..If something which really matters, is the amount of core in ur cpu..
But, if u still want to keep it at 4.8, i suggest u to have a liquid cooling in ur pc rather than air cooling.
really, 4.0ghz to 4.8, only 4-5 increase in fps, is it worth ?

Just to be sure, the 6700K turbo speed is 4.2 GHz isn't it? So won't it be 4.2 GHz vs 4.8 GHz? I am sure a demanding game will stress the CPU enough so it runs on turbo 4.2 GHz speed? Or am I wrong here?

The stock speed is 4.0Ghz and turbo speed is 4.2Ghz. If a program or game needs the extra performance the stock CPU speed raises up to the turbo clock speed. In my overclocked state the CPU runs constantly at 4.8Ghz with idle temps of 33°C average. Ingame i've got temps about 50 - 65°C depending on the game. I've got the high temperatures mentioned in the title only when running pure CPU Benchmarks vor burn-in tests.

85 under something like prime95 can be accepted. You'll never see that in a realworld scenario, like a video game.

Just saying.. but the CM v8 is a junk cooler in terms of performance/price.

85 sounds very normal for such a cooler with a 1.33v CPU applied to it.

In important aspect of aircooling it is the airflow in the case, you must ahve a very good airflow, and lots of fans

I have an i7 6700K with air cooling too and I run into those temps @ 1.305Volt 45GHz. What am I doing wrong?

LuckLess_7 :

Every CPU is different. My 2500K would clock nice at 4.4 ghz and 4.6 ghz, but 4.5 ghz would just wreak everything. No CPU is ever the same.

Perhaps you guys are missing the point of overclocking. Its not a question of if you need it or not, every single game on the market is designed to run with stock specifications. Overclocking is about pushing your system to its limits. It isn't a question of what is needed, but what can be done.
