So I just rebuilt my PC no more than a few months ago with the following hardware specs:

CPU: i7 7700k not overclocked
MB:Gigabyte Z270X Gaming K7
GPU: EVGA GTX 1080
CASE: Phanteks P400
COOLER: H100i w/ fans blowing out the front of the case
THERMAL COMPOUND: Arctic Silver 5

Just recently I starting monitoring my CPU temps and noticed they were very high:

Idling: 45C to 64C
Under load: 65C to 90C (the highest being 98C)


Some of the things I have already tried:
- Reinstalled the H100i water block (making sure it's level) and using the rice method for thermal compound. The backplate was loose but tightened up when the waterblock was mounted.
- Checked the BIOS for voltage settings but couldn't change any of them
- Replaced my liquid cooler (with new compound again) with my old Hyper 212 Evo and saw a slight improvement in CPU temps
- Changed the direction of one of my case fans with no improvement

I contacted Corsair about this issue and performed some of their troubleshooting. They began the RMA process but to me the cooler seemed to be operating fine. Even when the PC was under load, the liquid temp of the cooler barely changed and maintain roughly 34C. Neither side of the liquid tubes were hotter than the other.

I should add that another thing I looked at was my CPU VID in HWMonitor which I noticed to be fluctuating between 0.694 V and 1.432 V. Keep in mind, I have not overclocking setup.

Does anyone know what could be going on?

 


Do you have any air coolers you can try with it?
 
Clear cmos. Turn off pc, unplug power, press power button on case for 30s, plug power back in, turn on and load bios defaults, save and reboot, go to bios again and load optimized settings if possible, save and reboot.
 
@aquielisunari The Hyper 212 EVO that I replaced my liquid cooler with is a air cooler. Had hardly any improvement.

I should add that I just changed my PC power plan in windows from "Balanced" to "Power Saver" and almost instantly my VID stabilized at ~0.755 V with my CPU temp not stable at ~35C. When I changed it back to "Balanced" or "High Performance" my VID and temps go crazy again.

@fry178 I'll give your solution a try
 


Just did this and still seeing the same results.
 


It is an EVGA 650 Watt gold that was purchased new in August 2017.
 
either board or win.

backup your data.
download true image from acronis (trial is ok), and backup the whole C drive to an external/different drive if possible.
compression is pretty good, so will only need about 60% of the space it takes up now (for the image).
make sure to change the settings for true image, so you make full/single backups, and backup the whole drive.

dl the latest drivers for the board (chip/sata/usb), also check if intel has newer ones than what gigabyte offers.
disconnect the pc from internet access.
clean install windows, shutdown right after install.
turn on, install chipset driver, reboot, install chipset driver again, reboot, install sata, reboot, install usb, reboot.
see if it still behaves weird, if yes, its 100% from the board.

if its not the board/the clean install didnt fix anything, you can install true image, point to location of the backup image you made, and restore it back to the drive.

if its the board, see if you can get it replaced/repaired.
i personally dont buy/recommend gigabyte anymore, as they tend to have less features/lower component "quality" than same priced asus/asrock boards, and asrock is the best on vrm/power phase quality right now anyway.
e.g. i can get a midrange gigabyte/msi, when i can get the next step up from asrock or asus.

besides that, they tend to drop in quality after the first reviews are out (for R 1.0) by re-releasing it (R 1.1 or 2.0 etc),
without mentioning anything on the site/box/description and not even dropping the price.

e.g. releasing a gtx x70 with samsung vram, after a couple of weeks there is a R1.1 with different ram (NOTHING else changed),
and it now clocks nowhere close to the samsung, actually led to issues/crashes since the new chip required more voltage than the samsung..

 


I've spent more than a few hours researching the micron vram in the nvidia GTX 1070 boards, and that was Nvidia substituting the micron chip due to shortages, not the 2nd party vendors.
 
thats was for the 1000 series..
what i meant, happened back with the 700 or 900 series and hynix ram, but neither asus nor msi did anything similar.

i dont mind them changing stuff, but NOT when its not clearly "shown" to possible customers AND/or without dropping the price.

and especially for the gpus, their heatsinks are the cheapest grade (besides maybe on their top-ocing cards), that i can only find on either low-priced cards from smaller companies (like pny, or some asian market only brand), when others like msi/asus/zotac charge me the same, while offering better heatsinks and/or include vram/vrm cooling etc.


personally i will never buy GB again (boards/gpus), as their parts arent really that much cheaper than other brands, while not offering the same feats/quality.
might have change in recent years (mainboards), but the fact that none of the 30 builds from the past 15y had any issues at setup/install/within 1st year, i will stay with asrock/asus
 
"...thats for the 1000 series and wasnt what i meant, since it affected ALL brands.
what i meant happened back with the 700 or 900 series and hynix ram, but neither asus nor msi did anything similar..."

i wasn't aware of the issue with those - i've just been wrestling with issues that finally nailed down to my GTX 1070 when i moved it to a 2nd computer and the issues followed it.

sorry
 
i was actually (wrongly) remembering the 1000 series issue (voltage ramping up to slowly for vram) when i posted,
so this made me rethink that it was a different issue (cheaper ram), and i was able to change/update my post to reflect that.

so all good ;-)

P.S.
lower the ram clock with afterburner by 5 Mhz, and you wont have any trouble with the 1070..
