I have an i76700k and concerned with my stock temperatures . I am getting 34 to 43c at idle. With spikes up to 50c which quickly return to the 34 to 40 range. Surfing the web it stays about the same. Playing games new games It is reaching to the 50 to 70c. This seems a bit high for me on the idle and surfing temps at stock clocks. There isn't much on the internet due to it being a newer chip. What I saw is most people getting 27c with a liquid cooling setup, even some fan and heat sinks are. I know these aren't critical temps to where they can cause damage, but I plan on over clocking, but afraid to because of these high temperatures.
I have re seated the water block 2 times and going to try a third time after writing this. I am using a NZXT Kraken X61 as my cooler with Noctua Industrial 3k RPM fans, so I don't have many doubts in my cpu cooling system. The case is a NZXT H440 with three 140mm Noctua Industrial 3k RPM fans. A very recent bios came out for my Asus Maximus Hero VIII and updated it hoping it would help. On prime95 I have only done a half hour stress test and it gets no higher than 80c. I only do short tests because I'm not going to be putting this through extreme conditions like that for extended amounts of time in my daily use. I mainly use for games, normal low resource programs like Photoshop. I don't do any video editing, but would like to be able to OC if I ever plan to.
I wouldn't consider myself a novice as I have been building my own computers as well as other's now for 18 years (wow, I'm getting old). Couldn't even tell you how many machines I've built but I would say definitely over 30. I have mainly been using AMD but have had 2 intel chips before and they were problematic. AMD had nothing current so I went with the i7. This has been one of my more extreme setups.
My setup is as follows:
Windows 7 Professional 64bit
i7 6700k Intel CPU
Tuniq TX-4 Thermal paste
Asus Maximus Hero VIII motherboard
Kraken x61 180mm closed loop liquid cooler with 2 Noctua Industrail 3k RPM fans.
Crucial 32GB 4X8 D4 2666 Elite CL Ram
Asus STRIX 980ti Video Card
Asus Xonar STX sound card.
Samsung 840 Pro 256GB Hard drive for OS
Samsung 850 EVO 256GB Hard drive
Western Digital Black 4TB Hard drive
Western Digital Black 2TB Hard drive
Western Digital Blue 1TB Hard drive
NZXT H440 Case with three 140mm Noctua Industrial 3k RPM fans (2 intake, 1 Exhaust not including the ones on my radiator)
CyberPower 1325va Battery backup monitored via USB
USB single foot switch which I use to toggle the microphone
Only the Samsung 840 pro and the Xonar card are not new to this build.
I will list my peripherals even though they may not be relevant:
Asus ROG Swift 144mhz Monitor via display port.
LG 22" 1080p monitor via HDMI
Logitech 6710+ Keyboard
Orico Hard drive docking station USB 3.0
Roccat Mouse bungee with 4 USB inputs
Asus Bluetooth 4.0 Dongle
Logitech G502 Mouse
Cambridge Audio DacMagic 100 Dac connected to the optical out of my STX sound card, which goes to my headphone amp. I am not utilizing the USB interface on it.
Wireless XBox controller
Logitech G13 gamepad
To measure my temps I have been using the NZXT Cam software, CoreTemp, and Logitech ARX control. They have all been reading the same numbers give or take a millisecond of each other. These temps just kinda bother me I guess. I had a decked out AMD 8350 rig before this and is now my HTPC and was max OC'ing to 4.6ghz at 1.5v and holding 29 to 31c at idle and wouldn't go above 50c under load using the predecessor to the Kraken x61, the Kraken X60.
Here is a pic of my temps as I write this taken from my desktop.
Thank you for any input.
