i7 7700k is this a safe temperature?

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.

  1. Perfectly fine for 100% load. You'll see a lot lower temps doing things you do on a daily basis.

  2. If you really want to see your temps drop, delid the CPU and put Liquid Metal between the CPU and the heat spreader and heat spreader and heat sink (no aluminum!). You will get 15-20C and love it.

  3. the 7700k definitely runs hotter than my 6600k did even when overclocked to the same speed

    so yeah got to blame it on some one in intels accounts department for wanting to save pennies by using rubbish tim again

    this might turn out to be the first cpu i ever had to delid

    though my cooling can handle it ok just not used to seeing temps as high

    Try turning hyperthreading off. I noticed several degree drop with it off. Depends on what you use your pc for though but most games actually perform better without hyperthreading on :wahoo:

    Also turning off XMP and using manual seems to help temps. I manage to push to 5GHz before hitting 80 deg at full load

  6. yeah i've actually come across a few games that actually do perform smoother with HT off which is disparaging :( although the games are few and far between.

  7. My temps went down 10 degrees with hyper threading off... maxing out at 68-69c
    Reply to Xeffx
  8. With hyper threading off I managed to get only 75c @4.6ghz which is nice considering most games dont support HT.

  9. ...Doesn't having to disable hyperthreading not make you really angry? I'd be livid.. That just makes it an incredibly expensive and very hot i5....

  10. 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

    No not really. I had an i5 6600 and decided to go for the i7 purely for the increased core speed for FSX as it relies very heavily on single core speed and very little else.

    I've got 5000MHz overclock on the i7 and FSX runs great in VR - with ORBX vector and landclass and FTX scenery addons pretty much maxed out. Running simulator at 50-60fps and VR at 90fps, Could get nowhere near this with the i5. As for other games the i7 is overkill and the i5 handled them all easily.

    I wouldn't have gone for the 7700k if it weren't for FSX/P3D. FSX only really used 1 core - although I have it tweaked to use 4 but using HT gave poorer fps - even tweaking to use 7 or even 8 threads and it hiked temps a LOT. I did a bit of research before buying and there are quite a few youtube comparisons of games with HT off vs HT on and there are very few games that take advantage of 8 threads - most actually do worst :ouch:

    But the i7 still has the fastest single core potential - irrespective of HT, with a few exceptions of older gen i7's maybe. The price difference is prettly negligible - even compared to the new gen i5 - there's only about £40 differencce between the 7th gen i5 and i7on Amazon and the 7700 still offers the faster potential single core speed. Also I could keep the same z170 mobo with the 7700k as compared with going back to say a 4790k. :)

    I guess mcnumpty's correct about the 6700k, although I wasn't sure I could get this to 5GHz but I still prefer the option of being able to turn HT on, on the rare occasion that I do a bit of mkv file converting:no:

  13. Yea makes quite a difference. Got mine to 5.1 only running the 4 cores and hitting high 70s, may push it a touch more

    Looks about right to me. Depends on your cooler and ambient as well of course. I only have a single radiator with push/pull fan setup. I tend to use Asus AI suite now to software oc when runnning FSX/P3D - these flight sims will push the limits of the cpu even at 5.1. The rest of the time (default) I leave it at 4.5 via BIOS.

  15. I have the same exact same setup 7700k 3200mhz Corsair 16gb gigabyte ultra gaming 1070 amp. But i use a thermaltake 360mm aio cooler. At stock i get temps around 60 on load and at 4.8 I'm hitting 80 on realbench but all stable. I do need some new thermal paste on my CPU tho as it's old artic silver 5 that i had lieng around .

  16. Undervolting cpu is another option. In OP pic first post, cpu is getting 1.37v which is very high voltage for 4.5ghz(because VID hits that much and motherboard obeys because voltage is on auto).
    I am running my 7700k currently on auto voltage and minus offset of 0.100v which equals 1.51v at max load.

  17. Complaining about temps and not delidding your CPU is just insane. Turning off hyper threading on a processor is also insane. My i7 4790K at 4.7G with 1.3V runs 100% stable doing anything. If you do stuff without AVX extensions it doesn't go above 65C on air. If you run AVX (Prime 95 v28.10) it will hit 78C on the hottest core. Now this is with hyper threading on and a room at 68 degrees F. Delidding and using liquid metal thermal paste on both sides of the TIM just works.

    According to intel max temp is 100C so you're in sped. http://ark.intel.com/products/97129/Intel-Core-i7-7700K-Processor-8M-Cache-up-to-4_50-GHz

    i realize its a bit late now, but you guys should really consider buying your chips from companys that bin them. i bought my 7700k from silicon lottery garunteed at 5 gig for the same price as a retail 7700k.

  20. Hmm.. 4949.05MHz isn't really 5GHz btw.
    Reply to ahnilated
  21. no but ive had it to 5.1 i just dont like my temps hovering in the low 80's . will again go back to 5.1 hopefully even more when i install my custom loop.im running a captain 240ex which is fine for mild ocing just not anything more.

    Did you delid your processor? That does help a lot.

  23. no not yet i could have silicon lottery do it for $50 but i think im just gonna buy the tool and do it myself, sounds like more fun that way.and yea even if i only got a 10c drop would be a mammoth gain for me .
    Reply to OuttaMyWay
  24. 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.

    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.

  28. 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

  29. 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.
