Random CPU Temps on Start-up

Hi,

I have a i7-6700K CPU. Normally, after boot up my cpu core temps will hover around 30C while idle. After gaming for hours the temps rarely exceed 60C with the Corsair H110i all-in-one cooler and the temps return to 30C almost immediately when returned to idle. I can leave the PC on for days with no issue. However, at times when I boot up my PC the core temps when idle(~5% cpu usage) will be anywhere from 50C to 90C!!!. And will remain at that temp until I shut the computer down. If I perform a restart immediately the problem persists. If I shut down the PC for several hours it will often return to normal temps but not always. The temperature doesn't spike to this range either. It sits at 50C or it sits at 75C, like that's the new normal. Which makes it impossible to operate or game. The temps increase to an unsafe region when under load.

I've done some basic troubleshooting, such as reset the heatsink on the all-in-one cooler. I've checked to ensure all drivers where up to date. I've made sure my virus protection was up to date. The Corsair Link software has issues at times. Sometimes the program lists my mobo and other times it doesn't. I have no idea if a problem resides there. All this confuses me since the PC works fine at times.

I built this PC a little over a year ago and this issue arose about 3 months ago but has been increasing in frequency. It was so rare before I didn't even realize what was happening. The problem is so odd it's hard to even explain in a message. I'll list some of my specs below, PLEASE HELP.

Windows 10

Intel i7-6700K
Asus Z-170 Deluxe mobo
EVGA 1050G psu
32gb G.Skill 3000 mHz DDR4 ram
EVGA GTX 1080 FTW SLI
1TB Samsung 850evo SSD

 
Hello... Do you have the correct cable connections to the CPU fan and System fan inputs to your MB?

The software use is optional with this unit... and the default BIO's settings for FAN and CPU FAN will work... there are passive and aggressive cooling settings/options in your BIO's for them.

If you were to un-install the "software APP" and monitor and run some tests using the MB BIO's Fan speed controls, do you get better/different results?
 
@RARRAF I have the pump set to 'performance' mode.

@Ironsounds, I have the original cables from the all-in-one cooler. The unit appears to operate as intended.

It's as if the voltage control to the cpu is out of control. It's just generating too much heat, the radiator continues to operate normally and does it's best to keep the cpu cool.
 


You need to see what's abnormal during the abnormally high temperature. As if is not is. Did you verify all your electrical numbers were where they need to be. Let's not just look at the CPU core voltage which can be 1.8V and higher. OMG! It's supposed to be at ~1.025!!!!!!! Dig a little deeper and see the individual reading for vcore and the rest. Take a screenshot so those of us that are in the know can tell you if a number isn't where it should be. http://www.overclockers.com/forums/attachment.php?attachmentid=145825&stc=1&d=1404139393 is an example from a MSI BIOS screenshot. The erratic behavior would seem to suggest a mounting issue. I did see you remounted it. It could still be wrong.

 
I have attached a screenshot of some BIOS settings.

This morning when I booted up, the CPU temps were at 29C. I played BF1 for about two hours, during which time temps were holding steady at 55C. The temp of the Corsair all-in-one cooler was at 40C. When I stopped playing the CPU temps returned to normal and the all-in-one cooler returned to a steady 30C. I booted in the BIOS to take this screenshot and when I loaded into Windows the temps were at 60C and holding steady?!

I did have a BIOS update in October.
 


Of course they will look good at the moment. The troubleshooting can't start until you see trouble.

Can you post your RAM specs. Mine are Kingston 1866MHz 2x4GB CL11 1.5V .

Aside from the it appears you have made voltage changes. Is it possible you made a mistake? Perform a jumper/cmos/ push button reset to start with a clean slate.

Fan settings. I control the fans and water pump through the Corsair Link software. The all-in-one cooler has plugs into the CPU-Fan header. The water pump has two different settings, quiet and performance. I always use performance, however, I never notice a difference in sound. The rpms do increase in the software monitoring program. If I adjust the fan profile in the software, the fans change accordingly. No issue there.

I have G.skill 3000Mhz 2x8GB 1.35V
