CPU Hitting 1.304V on its own.

[hssnkhalid]

here are the specs of my pc

CPU i7 7700k (not OC)

MOBO : GA-Z270X-Ultra Gaming (rev. 1.0)

Cooling: Cooler Master MASTERLIQUID LITE 240

Ram: CORSAIR VENGEANCE® LPX 16GB (2 x 8GB) DDR4 DRAM 2400MHz C16

PSU: Corsair RM750X.

Case: thermaltake Commander C32

i am a little confused or might be wrong right now.

my CPU was hitting high temps during gaming, (80C-85C) during gaming, i had a small cooler on it before, Cryorig M9i, i bought this cooler because i thought it can handle 7700k with stock clocks, but i was wrong, i even added a high RPM second fan and it did bring the temps a little down but i was still hitting 80C, so i thought about changing it to a liquid cooler and i bought cooler master liquid cooler mentioned above. it did bring the temps down, but when i stress tested the cpu through prime 95, it was still going to 90C after 15-20 minutes(with old cooler it was those temps at 5-7 minutes). but during normal gaming i never crossed 80C.

i was still confused and looking at HWMonitor for answers like max power and voltage stuff and then i saw this.

 

 

 

if you look at the voltages, they went as high as 1.304v on its own when the voltage in bios is set to 1.224v(default). i cannot understand this, is this the reason the cpu is constantly getting hotter ? do i need to set a voltage limiter some where in bios. during the prime 95 test the power went above 100W and around 103~W it started hitting 90C and i stopped the test there. the fan and pump profile for cooler are set to max at 80C. 

what am i missing here.

VID is not the number to look at, Vcore is the somewhat right one but it's best to find VR Vout (which is the voltage controller's intended output). HWmonitor is poor for this, HWinfo sensor mode is the way to go. In fact I dont understand why people still use HWmonitor when HWinfo is clearly better and still available for free.

 

As for temperature, maybe it's just paste underneath the IHS.

Or a cooler that is not seated correctly

i have changed the thermal paste twice and reinstalled cooler, but the results were consistent, next thing i am going to do is changing fans to SP fans, i dont have any idea which ones are better. and then i ll try to change the paste.

i just installed HWinfo andmay be HWMonitor is a little more user friendly, but i dont usually use it that much, normally i use MSI After burner for temps monitoring. 

 

i am not even sure if changing the cooler at this point is gonna make difference, i ll try to change the fans first, then thermal paste, and then may be cooler.

 

but coming back to your answer, does that mean that HWMonitor is not showing the correct Voltage values ?

VID is essentially the voltage that the cpu asks for

VDD is what you provide 

VID doesn't show what actually voltage you got at the moment

ooo, ok, thank you.

 

can you tell me which entry to see in hardware info for that.

 

 

this is what i am seeing right now.

from this pic i can only see the VID

if you want cpu-z (imo ) is easier to read than hwinfo64 

it should show both the VDD and the VID

You have to start HWinfo in sensor mode.
