CPU temperature

    There has been a lot of talk about FPS but I don't seem to have found discussions about CPU
    I have recently changed the CPU and I switched from an I5-4690 (4 core) to an I5-8600 (6
    After many tests I can say that the CPU in ACC heats up much more than other games.
    Here are some examples:
    In ACC at Monza 15 hours with 20 car graphics all HIGH or all ULTRA (does not change much in
    performance) CPU temperature 75-80 degrees.
    In AC at Monza at 15 hours with 24 car graphics all FULL CPU temperature is 60 degrees.
    In Euro Truck Simulator 2 the CPU temperature is 45-50 degrees.
    In War Thunder the CPU temperature is 50-55 degrees.
    With the old CPU the CORE worked at 90-100% in ACC.
    With the new CPU the COREs work at 50-60% in ACC so not even put under strain.
    On the CPU I mounted an Arctic Freezer 11 LP heatsink and I'm sure I mounted it well because
    in IDLE I have 31-32 degrees.
    As a video card I have a GTX 1070 and I saw that without v-sync I have GPU temperatures of
    77-78 degrees while with the v-sync active I always have GPU temperatures of 55-56 degrees so
    I decided to keep the v-sync activated.
    I wanted to know if you too have very high CPU temperatures only in ACC.
    If I wasn't clear it's google translator's fault.

    Your temps in ACC are high, but not too high. Part of the problem is almost certainly the cooler you're using. It's an old design and wasn't built for modern, high performance CPUs. If you're using it because it's slim and you need that to fit in your case, then there are much better alternatives available. If it's just because it was left over from a previous build, it's time to retire it! You have a good processor which deserves a much better cooler to keep it running efficiently. A good, modern cooler would probably knock at least 10 degrees off your temps.

    What are the CPU loads in War Thunder and Euro Truck Simulator. If they are lower than in ACC, that's your explanation right there.

    Don't know why the temp would be higher with the 8600 than with the 4690 - 8600 has 65 W TDP as per Intel specs, 4690 has 84 W. TBH I don't really believe that claim for now.

    Its "TDP", there are limits for clock speed and time for those, but mb manufacturers ignore those and specially these new ones take much more power and so generate much more heat

    thanks to the answer, the CPU loads in the other games are obviously much lower.
    Sorry, as a CPU before I had an I5-4690S with TDP of 65W and even with that CPU I had high temperatures of 77-78 degrees with ACC.

    so would you recommend another cooling fan? I thought the Freezer LP 11 was good but I will try better. As a width of the case I should have no problems, do you have any suggestions? thanks.

    It may be that ACC is heating the CPU more than other games.
    Yet i'd suggest you to double check your cooler, as those temps are quite high.

    I have a I5-8600K and its max temps never exceed 65°C.
    Noctua NH-D15S installed.

    renato63 Gamer

    yes, but in IDLE it remains about 31-32 degrees, maybe I first look at the output 1.0 of ACC to read if they managed to optimize it, thanks.

    Do not exceed 65 degrees in ACC? And what cooling did you install? Thank you.
    "Noctua NH-D15S installed", sorry I had not read.

    I shouldn't have referred to the TDP. I only recently read some CPU review saying that the Intel spec sheet figures don't say much about the actual power consumption. I won't use thopse numbers, anymore.
    For what it's worth - here's Intel's explanation on the test procedure:

    Source: https://ark.intel.com/content/www/u...5-4690-processor-6m-cache-up-to-3-90-ghz.html

    This all seems logical - less CPU power leads to less heat. And old CPU got as hot as the new one.

    I'd also triple check the cooler - proper installation and fans. My i7 8700 is always between 65 and 70 degrees with the small Coolermaster Hyper 102 running very quiet.

    I would not worry about running 75-80 degrees. It is fine to run all day long... 90+ then I would be more worried. I have good cooling however I live in a hot climate so I regularly run at 80 degrees whilst under heavy load.

    It might be worth running some tests with the case cover removed to make sure your airflow isn't a factor. Those temps are fine but a little on the high side for both a non oc chip and a 1070. Any issue with the cooler mounting wouldn't show up until under load either, so don't completely discount this but with both components a bit warm I'd check for airflow first.
  16. renato63

    renato63 Gamer

    yes I'm not worried, I know the CPU limit is 100 degrees.
    As I said before, I wait for the release of v1.0 of ACC to see if they have optimized it and then decide whether to change cooling, thanks.
  17. renato63

    renato63 Gamer

    yes I have already done the tests even without the side cover and there are no variations, thanks.

    I would not expect too much. The UE4 is heavy on CPU.

    I have an i7 7700k CPU, I use a CooleMaster liquid cooling "master liquid pro", in play with a 4K monitor and with fps 70/80 the temperature settles between 60/65 C ° even with 24 cars.

    GPU temps are a little high too....Are you sure that the chassis cooling fans are well mounted? When I assembled my first PC i got a little high temperatures, repositioning the fans helped to cool down.
    You can find some videos on YT about case air flow

    Just for info, I run a i7 8700K@4.9 GHz, never gone above 75° (with a room temperature of 28° and more), same for the GPU, as in specs and overclocked, never above 69°

    It depends on your budget. If that's not a problem and you want an air cooler, the Noctua NH-D15S is very good and is a little more compatible with different RAM sticks than the NH-D15. However, check that it will fit in your case as it's very big. If you prefer an all-in-one liquid cooler, I'd go for the Corsair H100i.
