i7-6700K Max temps coming at around 90°C while playing a game, is that too hot?

I have an i7-6700k.

For cooling I am using the Corsair H60 with 2 Corsair SP120 fans as Exhausts.

The temperature sits at around 23°C-30°C when I am not doing much however the Max temperatures can go to 90°C when playing games. I feel like that's too hot.

EDIT:
When idle cool air comes from the radiator. When gaming the air is hot only coming from the radiator of the H60. Air coming from the case Exhausts stays cool.

Just testing by playing PlanetSide 2 for a few minutes:
Maximum: 91°C
Average: 69°C

  1. Assuming you running stock speeds/voltage. Yes that hot. Check if the H60 pump is running and the water is actually flowing.
  2. even with an overclock thats about 15degrees too hot
    check your case cooling, especially that H60,
    you have no intake fans?? only the 2 SP120 for exhaust?

    I have 2 intake fans coming from the front. 4 Exhaust fans(2 of them being the H60's fans). The case has holes on the side where two extra fans can be placed so that lets in more air. The air coming from the case Exhaust fans is cool. Only the air coming from the H60 fans is hot.

    I don't know how I would do that. I know that hot air is coming from the radiator so I assume its working.
  5. 90c is hot, but not unsafe.

    Does the waterblock feel hot to the touch? Does the radiator feel hot to the touch? Is the fan blowing off hot air?
  6. are you sure the h60 is seated properly on the CPU paste and all?
    im running on air and OC and im getting nowhere near those temps..
    and your cooler should be adequate if seated right and functioning proper...

    any chance you got like a "power virus" or something like prime95 running in teh background lol... very strange..

    "Sustained Core temperature greater than 80C is too hot for ultimate stability, performance and longevity" directly from the guide
    id venture to call his 90c on gaming temp way too close to dangerous for comfort
    considering he is not overclocking there is not teh added voltage, so the heat makes even less sense

    The block get slightly hot and the air is hot coming from the H60's radiator. When idle the air is cool. When gaming the air is hot.

    H60 is seated properly. Actually my motherboard seems to Overclock it to 4.6Ghz.

    Which guide? The one on this forum? I read through the articles cited as reference, and could not find any data to back up the "80c" figure.

    Notebook CPUs run at 90-100c for years. OEM desktop PCs run at 90-100c for years. Intel warranties their CPUs up to throttling temperature, which is 100c on Skylake; these CPUs will happily run for years at just below throttling.

    Intel rates the maximum Tcase temperature, which is the temperature on the surface of the heatspreader, to be 71c. This is a factory calibrated number that is supposed to reflect what the top of the heatspreader is when the cores are at maximum temperature. So, cores @ 71c != heatspreader @ 71c.

    I agree that it's not optimal to be up near throttling temperature, in case the CPU actually does throttle. It's also a very good idea to be well away from those temperatures if you start adding clockspeed and voltage, because it's a combination of voltage and heat that cause degradation in CPUs. I additionally agree that 90c is warmer than I'd expect given the chip, cooler, and clockspeed, so something is probably off.
  11. If your CPU is running at 4.6ghz with auto voltage, that temperature actually seems about right. Can you check and see what voltage it's actually getting?

    thats prob why, tcheck your voltages
    my motherboard did teh exact same thing, it just upped the voltages to something crazy like 1.48, i couldnt turn it down fast enough
    bios might say its 4.0ghz and stock voltages, but if it auto overclocks to 4.6 its definitely drawing more voltages too
    run hw monitor or aida 64 and check voltages while gaming

    I'm not sure which would be that information. Here's what I think could be:

    On HWiNFO64:
    "CPU Current: 4634.1 MHz = 45 x 103.0 MHz @ 1.3468 V"

    Is that it?

    Also updated the question description:

  14. yup thats an overclock alright , just glad yours didnt dial up the voltage as much as it did mine ;)
    good thing is those voltages are safe, no worries there
    what you want is to lower the voltages (should be possible even while staying on 4600Mhz)
    What BIOS are you running?, need to tweak those voltages a tad in there so you dont run so hot
  15. Those temperatures seem about right. The Corsair H60 has only a 120mm radiator, and thus has no more cooling surface area than an air cooler of similar size. You'd see similar temperatures with a Hyper212 I'd imagine.

    1.3468v looks right for those clocks. Most people throw around 1.4v as being the upper safe limit for Skylake, but this number didn't come from Intel. However, lower voltage is better, because ultimately voltage is what degrades a CPU over time, and temperature goes up exponentially with voltage. See if you can dial that back a little bit, and you'll see your temperatures drop dramatically.

    My i5 3570K running at 4.0ghz @ 1.192v stress tests around 80c, for instance, but at the same clockspeed with voltage lowered to 1.064v, I can shave around 10c off of that.

    Just don't go so low that you cause instability.
  16. also, i wonder why the z170/6700k prefers to autooverclock by going mutltiplier by x45 and BCLK by 103... mine did teh exact same thing.. so strange

    I played the game again for a few and the Maximum voltage I got from HWMonitor was: 1.471V.

    I believe the BIOS version is: American Megatrends Inc. 1402 as found in the System Information.

    I've never overclocked myself so I wouldn't know how to do that. I will look into though. Thanks.
  19. a good place to start for the i6700k @4600Mhz would be 1.32 volt, now thats ofc if you are going to actually start overclocking it proper,
    otherwise for now, just need to somehow change the autooverclcok back to stock, so it doesnt go more than 4.4.Ghz on boost and doesnt do more than 1.3 stock volt (think it was something closer to 1.28 stock tho but chip varies)

    yuuup those are near the same nasty voltages my board gave me when it thought it was being funny, that need to change real fast
    and sry by BIOS version i mean, Asus, Gigabyte, ASrock,? (what is your motherboard model, who made your motherboard)
    because their BIOS layout varies slightly so having the precise one would make it easier to guide you in BIOS and turn it down

    hahahahahaha i should have know,, system acted too similar to not be the same as mine ;)
    alright, head into bios, hit F5 to load defaults, start with that, (makes sure it actually saves)
    when you are back in windows, open up HWmonitor again/Aida64, and run the game again and see if its still being naughty regarding voltages

    I'm getting the same results. I think the motherboard does the overclocking by default. I think it tries to overclock everything one at a time when it is turned on.
  24. yea i did suspect that would happen,
    try this, in bios, hit F7 to get to advanced screen, then disable SVID in tweaker(AI tweaker or extrme tweaker, name may vary)
    that should stop it from sucking that much voltage

    yea the only problem is just it isnt very "smart" even though it might think its clever, why or where its getting those ridic OC profiles from in auto i dont know,
    and a BIOS update wont fix it cos im on 1601 or whatever the latest version is, and mine did that exact same too

    It won't turn on now that I've disabled it. I can only go back to the BIOS.
  27. alrighty,
    back in bios, same area, advanced, tweaker, there should be in the same area where the SVID optin was (still leave it disabled) an option for Ai overclcok tuner? what is that set to? auto, manual or xmp?
    if its auto set it to XMP,, and if its XMP set it to manual

    in either case a bit below should be an option that says BLCK frequency (not ram BLCK, and it should say about 103 i belive since thats what it clocked it to) change that to 100
    and there should be a tab called cpu core ratio, set sync all cores, on teh first tab, core 1 ratio which would be set to 46, set that to 44
  28. It's set to manual. I've done the changes and still won't turn on. I have to turn of and restart manually to get back to BIOS.
  29. back to bios hit f5 load defaults
    it was set to manual before you made the changes?
    if you f5 and load defaults and go back to that same tab, is it set to auto, xmp or manual by default?
  30. It is set to Auto and so are the core ratio limits.
  31. good
    and now sync all cores and change the core ratios back to 44, and BLCK frequency to 100(im pretty sure BCLK frequence wont show up because ai tuner is on auto and thats okay)
    do that and check if it boots
  32. It has booted but it looks like it's the same. Saying turbo is at 4600. VID has a max of 1.485V
  33. what the heck.. thats not possible... hang on i need to find a wall and bang my head.. be right back
  34. There's a program called AI suit 3 here I just found. When I changed things there. Now turbo is at 4400.
  35. whats your power plan set to in windows?
  36. great, try rebooting, and see if it behaves this time when you open teh game
  37. sigh.. that moment when you realize how much of a numbnuts yourself are.. sigh..
    i completely forgot about asus ai suite, because i didnt like it so i didnt install it, since i prefer to change directly from bios myself

    but ofc if you have it installed, i bet i overrides any bios changes you made to teh clocks, so they got set right back to 4600 when loading back to windows and ai suite took control lol..
    sigh..
    so sry for being senile and forgeting about that program..
  38. in either case, if your computer happens to be set on "High Performance" mode, in windows power plan settings, change it to balanced,
    that should makes boost more stable too
  39. Can't blame yourself for not know if I had it though :/.

    Its set to Balanced already. The Max voltage was at 1.503 but the Max clock was at 4404 Mhz.
  40. holy hell.. voltage increase with lower clocks.. what is happening.. i am literally dumfound now

    there be Gremlins around messing with some auto feature somewhere...
  41. can you check the voltage control section inside the suite and see what its set to?
    and if possible see what it has set the OC voltage too, or if you can lower the OC voltage tab/slider (but without changing settings such as manual/adaptive)
    because if you can atleast limit the max voltage its allowed to draw that would be a start
  42. On AI suite 3 I can lower the CPU core voltage(Default at 0.075), CPU standby Voltage(Default at 1.0) and a few more.
  43. im looking at a tab that says TPU it should be in there, atleast according to what im looking at, ofc your version might vary
  44. something like this

    that slider im mighty interested in to see if we can get down to atleast a maximum of 1.35volt
    (even tho thats also technically high for a stock 4400 boost, its still better than 1.4-1.5)
    the slider on the CPU core voltage, not the cache
  45. This is what I see:
  46. alright start by changing the ratio to 44 and save profile, (cpu ratio not cache ratio)
    then if you move the slider CPU core voltage, back, as you move it back does the first values closes to teh title name change? or only the values right beside the slider?
    and as you slide it back (gently) what does the value cahnge to
    (because i would read that as its curently at 0.075 volts but i suspect the slider is set to something higher and the current shown is not the slider value just what its drawing in that moment)
    but please check and confirm my thoughts before saving
  47. I changed it to .060 and I didn't see change.
  48. was that the slider you touched or did you just type in the actual number/value in teh box?
  49. I found a Threshold column at the bottom:

    I used the arrow to move by - .005
