Hi, I recently built myself a new gaming rig and belive im beeing a bit paranoid about the temprature of my cpu but would like to get a second opinion.

This is my build:

PSU: Corsair AX 1200i, 1200W PSU
Motherboard: ASUS ROG Maximus VIII Formula, S-1151
RAM: Corsair Dominator DDR4 3400MHz 16GB
CPU: Intel Core i7-6700K Skylake
CPU cooler: Corsair Hydro Series H100i v2
GPU: ASUS Geforce GTX 660 TI (Going to be replaced by a ASUS Geforce ROG Strix GTX 1080)

Case and fan settup:

Im using an Phanteks Enthoo EVOLV ATX mid tower with the following fan settup:
3x Corsair Air AF120 Quiet in the top mount blowing air out of the cabinet.
1x Corsair Air AF140 Quiet blowing air out of the rear exhaust.
1x Corsair Air AF120 Quiet in the bottom intake slot blowing air on the cabinet hard drive case.
4x Corsair Air SP120 Quiet mounted in the front intake configured in push pull on the Corsair H100i V2

The Idle temprature on most of my components are around 29 - 32 degrees Celsius witch im happy with but the issue is mainly with my cpu. First of all the CPU package fluctuates from around 28 to around 36 C and sometimes even up to around 57 C (it only jumps this high after a session of gaming so i guess thats normal). My cooling block however usualy is steadily at around 29 C and only usualy goes up to 35 c when gaming but the CPU package goes up to around 58 - 64 C. When stress testing the cpu with a 100% load the temp was around 69 - 73 C and the cooling block rose to around 33 C

Is this normal or is something not right? The only thing i can think of is that i should have replaced the stock cooling paste that comes on the H100i V2 cooling block.

Hopefully someone is able to respond and i thank you in advance (Sorry for bad grammar English is not my first language). :wahoo:

Contrary to the other opinion expressed here, which is inaccurate, there is no problem with any of those thermal readings. They are normal.

Temps in or below the mid 70's for 6th Generation Intel processors while under a 100% load is perfectly normal.

If there is anything you still don't understand, I'll be happy to offer whatever clarification I can.

The VCPU value is on 0.80 usualy but can rise to about 1.40 is this the value your refering to ? will ceck the BIOS Value and get back to you (This VCPU value and tempratures are messuerd from the corsair link software by the way if that matters)

Update:

Here are the values from BIOS:

CPU core Voltage/cache Voltage : 1.280
CPU VCCIO Voltage : 0.968
CPU System Agent Voltage: 1.064
CPU Standby voltage: 0.993

DRAM Voltage: 1.200
PCH Voltage: 1.008

Standard PSU values:

+12V : 12.000
+5V: 5.000
+3.3V: 3.313

I also noticed that my CPU temprature in bios was only fluctuating between 31 - 32 C can it bee that the corsar link software is playing tricks on me ? is there any other reliable software that you recomend i test with ?

I have tried pressing down on the cooler and the temperature did not change, The BIOS temperature was also immediately after a reboot after the mentioned stress test. I have however made some headway. By setting the power profile in Windows to high performance instead of balanced, this made the fluctuating in the cpu voltage stay at 1.36 instead of going between 0.800 up to 1.400

This made the temperatures more more stable at the same stress test I preformed yesterday the cpu was only about 61-62 C (around 10 degrees lower than last time ) and only peaked to around 66 C a few times.

Also my ambient temperature is higher than normal as it is a small room (I'm not sure but would bet it is around 24-26 C)

Thank you for the information that guide helped me understanding the behavior of the CPU allot more.
For some reason setting the power plan to high preformance leaving the CPU core voltage at 1.36 instead of letting it go up and down in power saving mode helped aloot. also.

No worries. My 6700k is totally stable at 4.5Ghz with 1.325v, using Trident 3000mhz memory 2x8GB on a Gigabyte Z170x-Gaming 5. Your setup isn't all that different actually. While your BIOS IS different, being an ASUS board and mine being a Gigabyte, the majority of Skylake settings are consubstantial across all the vendor boards. There may be a few minor nomenclature differences from brand to brand, but mostly they are the same.

Here are my settings if you decide you want to do some further tweaking, you might find them useful, and you might not need or want them at all. Either way, gives you an idea of what other people are doing.

Thanks for the info i will look into setting some of these values myself, I see you have turbo boost disabled is this for stability purposes or personal prefrence ? (I have read that turbo boost only activates if one of the cores are unused)

Turbo is generally not only useless, but problematic on systems with a manual overclock configured because it can destablize an otherwise stable overclock. It can also create heat issues. Turbo is controlled mostly by the system, with a few configurable user input settings, but a fine tuned overclock can be undone because with it enabled the system has the right to make adjustments to the voltage and multiplier, and those changes may not be desirable or necessary. Often times, the overclock is already higher than the max turbo speed anyhow, or if percentage based, may allow the system to turbo beyond your overclock setting, causing excessive heat or instability.
