i7 7700k is this a safe temperature?

[Xeffx]

So I have an i7 7700k, Gigabyte Z270X Ultra Gaming, and 3200mhz ddr4 ram.

CPU cooler: Noctua NH U9B SE2

Here is an image of temps, voltage and all that funky stuff.
Is that a good temperature for full load?
Idle is whats minimum on that image file. Had to lower the voltage to control my temps.
Fan speed had no effect, nor did thermal paste, no heatsink trouble. I just think it's the bad TIM.

Well the higher you overclock the more gain you see it seems. Also if you run AVX extensions on it makes a huge difference in temps, mine were over 25C then.

out of curiousity what off set are you running on avx ? mines set to 7
also too you guys if your unsure of how safe or close your temp is to being unsafe you can download the intrel diagnostic tool here https://downloadcenter.intel.com/downloads/eula/19792/Intel-Processor-Diagnostic-Tool?httpDown=https%3A%2F%2Fdownloadmirror.intel.com%2F19792%2Feng%2FIPDT_Installer_4.0.0.29.exe this version is for windows only. it will run a stress test on your cpu and tell you if your temperatures pass as safe by intels guidelines.

I don't run an off set. The system can run full speed without temperature issues.

i didnt pay 350 quid for a 7700k and then turn off hyperthreading

would just have got a 7600k and saved myself 140 quid if that was what i wanted

luckily for me even at 5ghz my cooling can handle it

but yeah i agree with crumpet i would be really annoyed if had to disable hyperthreading to get temps under control

i use my pc for much more than just gaming so i want all 8 cores/threads i paid for running

There is a very simple solution to this dilemma:

1. You buy an i7 to get get improved multithreaded performance as each physical core presents your software with two virtual / logical cores. Yes, in apps that take advantage of multithreading you will see a performance increase with the 7700k

2. In recent generations Intel has boosted the out of the box clock and the higher base clock certainly contributes to the improved performance .... but even when both set to the same clock speed the i7 has the edge because of the extra virtual cores.

3. However, as has been said multiple times on this thread, we don't see gaming, at present anyway, benefiting in any way from the extra virtual cores.

4. And yes it is true that HT makes the CPU run hotter (7-10C reported). Running less threads / virtual cores delivers lower temps and, along with other factors / settings adjustments, it is possible to get a higher stable OC with HT turned off.

So now to that solution I was talking about. My son was an avid gamer (stil is) and when he was in college he minored in media arts using PhotoShop / Premiere. He had a 2600k and he faced your same dilemma .... optimize for media apps or optimize for gaming ? Why not the best of both worlds ? ... Most modern era enthusiast motherboards allow for saving BIOS profiles so here's what we did:

A. We tuned / tested BIOS settings with HT on hitting high core temp of 79C in the stress test ... little higher than we wanted but considering a) nothing (other than P95) will ever drive the CPU temps to those levels so it will never see that again, b) TIM curing will improve that over time and c) tweaking would improve that over time, we left it alone. Saved these BIOS settings as "WorkSta" profile and eventually got to 75C max temp on hottest core.

B. We then tuned HT off hitting temps of 70C in the stress test ... went on tweaking the BIOS and managed to get an extra 0.2 Ghz stable with a highest core of 80C ... eventually got that down to about 77C and saved that as "Gaming" profile. When booting the PC, he would simply choose which profile to boot from depending on whether he was Gaming or working in Premier. There was a difference in gaming performance in some games not others .... but in the ones that mattered most (FPS multi-player) it was figuratively at least ... sometimes made the difference between life and death

That box has been handed down to a younger brother who still uses it today w/ a GTX 1070 and is still going strong, even tho the workstation profile is rarely used since he uses nothing in frequent use that benefits from the 4 virtual cores that HT provides.

i do much more stuff that requires the hyper threading on than i do gaming any way

and luckily my cooling can take it any way

but for people whose cooling isnt quite as effective yes 2 bios profiles might make sense

Try updating the bios on your motherboard. I noticed with both my 6700k and 7700k both my mobos decided to set the stock cpucore voltage too high for stock K speeds. On the asus z170 a I just manually dropped the voltage to 1.25 the turned on power saving options so it would drop voltage when not under load. The 7700k voltage was around 1.375 stock then after I updated the bios on the gigabyte z270 k7 mobo the voltage dropped itself to 1.25ish and I seen temps go from 90c under load to 60ishc under 100% load. These small voltage changes make a big difference in temps...just remember to check for stability after lowering your cpucore voltage.

Hi. I just bought the i7 7700k few days ago and i also have the same CPU Cooler as you do.
Okay i have done the same cpu burn test as you did and here are my results:

https://imgur.com/mRk8xH9 4.5GHZ
My build:
ASUS Z270 TUF MARK2
INTEL I7 7700K 4.2GHZ(Turbo 4.5GHZ)
NOCTUA NHU9B SE2
8gb DDR4 2400MHZ
W10 PRO x64
Have my bios updated to the latest and all drivers are up to date.
My thoughts: I am a gamer i play games a lot but not an extreme OC Gamer, i dont have my gpu bought yet, it is on the way, cant wait for it! Anyway about this CPU Cooler, if you want to play on 4.5GHZ then i wouldnt recommend this, i read about the safe temps for a cpu it shouldnt go above 80 degrees but still being higher than 75 is quite a lot.(least for me) I will do more testing once i get my GPU . I am using the black RPM adapter which has much higher RPM speed therefore cools the cpu more efficiently and still very silent!
As you see in the pictures with the Turbo boost on it goes very high... i ran the test only for a couple minutes and it was already on 77 degrees! imagine running the test for 5 hours? i bet it would go up to 80s even until 90. I heard about delidding this cpu but why? do i want to damage my cpu? nope, the safest way but more expensive one is to buy the NHUd15 Noctua Air CPU cooler (look it up on amazon or newegg) and keep it cool if you want to OC this beast. If not then just turn off turbo boost and your temps go way down 5-10 degrees. my ambient room temperature now is about 20 degrees.
See proof in next picture without turbo boost it goes up to 65 degrees.
I love noctua cpu coolers they are the best air premium coolers available on the market i just think this one doesnt cut it for 7700k, not if you want to OC it. More safe and cooler at 4.2ghz without Turbo boost.
Speaking from my own experience. It all depends on each game you play. Some use more of your cpu and some less. It varies.
And ignore the 127C on hwmonitor. That is a false sensor! haha
