Kaby Lake 7700K - Really spikey temperatures

post #1 of 7
Thread Starter 
First and foremost, apologies if this is in the wrong area but I have been reading nonstop for the past 4 days about the 7700k since upgrading to it. Always read these forums for years, but never posted or made an account for that matter.


The rig is;
i7 7700k - 4.5Ghz (Won't throttle down to standard 4.2ghz automatically)
This is cooled by a Noctua NH-D15
Asus Strix Z270-E Gaming motherboard
16GB 3000Mhz Corsair LPX ram
EVGA GTX 1080

All in a Phantek Enthoo Evolv ATX case.

At Idle, the core temperature hovering around 31c, with the current room temp being around 23c.

Motherboard settings are all on Auto in terms of voltage (Hovers around 0.7 up to 1.275 when checking HWMonitor), and only XMP enabled for the RAM to hit 3000MHz (which is rather temperamental when first changing but boots after 2 automatic resets).

When playing Metro Last Light at 1440p it shoots up to about 63c max, same when running the Cinebench test. Just idle, the processor starts to do some work with background processes and the temperature shoot from 31 to around 55 and instantly back down.

Just at a stump on how to best solve my temperature issue, I read all about the De-lidding but the chip is only a few days old and I never tried it before. I have looked all over for somewhere in the UK to offer a similar service to SL ($38 shipping both ways kills that idea for me.)

I have 2 Noctua 140PWM fans on the front blowing in at about 60% minimum speed, with a Phantek 140mm mounted on the roof just in front bring air in and finally a Phantek 140mm fan blowing air out at the back just behind the Noctua. All of my fans run at 60% apart from the CPU hits 55c then it will go to 100% as the spikes cause any other curves to just have a constant spin up and down sounds.

Any help would be appreciated.

Attached is the HWMonitor readout from just leaving it Idle and loading some webpages (Youtube videos etc)

The simplest solution would be to change your cpu fan curve, so it is not so aggressive and does not ramp up to full speed at 55 degrees.

The cpu spiking up and down is normal and the temperature difference of your cores is perfectly fine.

On top of adjusting fan curves, you can also lower your cpu vcore voltage, and your temps will not spike as much.

You will have to experiment and lower the vcore by 0.01 volts at a time, until you find the lowest volts that are still stable.

change voltage from auto to manual its best.whit offset or adaptive respective auto motherbord will do overvolt.hapens to me to from 1.34 to 1.4 so i set it to manual and no more spikes.

I will give that a try, I have never tried manually adjusted voltages before.

Any tips?

Apologies, I meant that my case fans start at 60% and end up at 100%. It is still blowing rather cool air out the back of the case rather than the expected warm air. My CPU cooler is at a bit of an aggressive fan curve. Just the noise from the case fans is a little off putting, but I am worried for the temperatures if I have them low and from the severe spike nature of the processor. I am finding it hard to find a balance between keeping it quiet and having it spin up and down constantly.

Cheers for the replies.

Quick update,
I have tried setting Manual voltage in the ASUS Bios to 1.2 but it is still seems to be hitting 1.268 still. I am guessing I am missing a setting somewhere?

Went into Advance Mode, then CPU/Cache Voltage from Auto to Manual and then entered in 1.200 before saving and exiting.

7700k - overclocked to 4.6ghz (via ez mode in bios)
16gb DDR4 corsair vengeance 3000mhz
Asus TuF mark 1
Kraken X52 cooler


Hi all,

I've got the same case and the same issues with my new 7700k - basically thought it was to do with radiator mounting so moved from top to front. Then checked air flow and removed case front. As you can see from picture below the cores are hitting 85 degrees in under 4 minutes using occt. sorry i am a complete noob to this, but other than buying new thermal paste and reapplying I am unsure what I can do.

Also i've never rma'd anything before and having bought this from an ebay seller (brand new) i don't know if the warranty is voided?

The temp spikes are literally game related atm. As soon as i esc out of bf1 they drop like 20 degrees something ain't right frown.gif

Any help on this issue would be great.

well my chip spikes to 79.c using Intel burn test,but I have used "HWINFO64" and I checked the average temps playing B1 or Dirt Ralley,GTA5,,and they are around the mid 50s gaming,i have no overclock headroom on mine and I plan on delidding the chip,when I get brave enough....
try HWINFO64,,game for a while and quickly check your average temps,,you might feel a little better,there an option to just run the sensers

btw how do you like the TUF mark 1,,i almost bought that board

also is your pump going full speed,on my board the AIO header was set to PWM by default,so it was only running at 60%,so I set to 100% DC
