What are good idle temps for my cpu and gpu?

My idle temps for my cpu is at 38-40C

and for my gpu its around 48-50C

Are these good idle temps or do they seem a little too high?

More about what good idle temps
  1. Forget idle temp
    for healty hardware cpu below 55c for amd and below 70c for intel under test stress
    And Gpu find your fulload gpu temperature when test stress.
    All Maximum temperature depend on your hardware
    See temperature in hwmonitor : www.cpuid.com
    You must test it
  2. How are we meant to answer if you don't even say what parts you're using lol.

    Anyway.. as henydiah said, idle doesn't really matter.. it's stress temps that matter.

    I had a CPU that idled at 45C (quite high) but stressed only ever got to 52C so it didn't matter. If you had idle of 15C that would be great, but if then stress was 70C we've got problems ;).

    Let us know what components you've got and we can give a better answer.
  3. If you have a 15C idle temp in an air cooled system either:
    It is winter time and your system is in an unheated room or
    You have a malfunctioning thermal sensor. :)

    Idle temps in an air cooled system (or most liquid cooled systems) will never be lower than ambient air temperature.

    And 70C is at the upper range of acceptable for load temps in a Core2 system.

    Like acer said, your components will make a big difference. This means everything:
    motherboard, CPU, GPU, case, fans, construction choices including cable routing, room temperature.
  4. Hehe yeah, didn't quite mean to put 15C as an example ;]. I did once boot my computer to find all 6 cores at 15C and CPU at 21C though.. middle of the worst winter in years and years lol.
  5. My i7-920 (OCed at 3.82 GHz) idles at 26 C in winter.

    The Dell in an unheated room idled at 4 C when I started it up to perform updates.
  6. My AMD x6 1090T at 4.0GHz is currently idle at 28C on air ;).

    Silly thing is.. this chip runs 10C cooler than my old x3 chip, which had half the cores and was only ever clocked to 3.6GHz.
  7. I recently had a athlon X4 640 idling at 13C. probably got into the 20's when running stress. Then I just threw a phenom X4 955 in and it idles at 30-34C idle and then maxes around 51C during stress. I thought it was quite the difference. Are you guys saying that my athlon wouldn't be reading right then? Or do they run that much cooler?
  8. Anything that idles at 13C means your room temp would be at least 10C - VERY chilly house you have there! Are you talking about CPU temp or CORE temp?

    I'm sorry,but what cooler do you use for your 955 phenom to keep it so cool?

    And as it said before. It's impossible for any proccesor unit to operate at temperatures bellow room temps.

    It's not impossible - the FreeZone Elite can hit sub-ambient temps, but it's a thermal exchange conductor or whatever it's called and also costs £200 - so yeah.. not really valid.

    I believe they were looking at core temps and not CPU temps, as some mornings I have woken to cores running at 15C or so (winter).
  11. Like they says, Idle temps aren't as important as load temps (mainly because you are using your PC for the time) but I can see your like me and freak out even if it rises 1C. Mine idles around 30 ~ 34 C with a heatsink and separate Thermal compound. On stress it doesn't go any higher than 47C.

    Processor: AMD Phenom II x4 955

    I think that might be the issue with me :( Here the ambient temperature is 38-42C and my PC goes upto 60C while playing BF3.
  13. My 4790k with stock cooler idle's and doing general tasks (like right now im on fb, Have skype open and downloading a torrent in uTorrent, while on youtube listening to music) at 27-30 Degrees Celsius and its been on for nearly 10 hours without going above 35 degrees. And my Gpu is sitting at 25 Degrees Celcious (saphire radeon r9 280x) Both are not over clocked, And i have two standard sizes intake fans, 1 standard size exhaust fan and one large side intake fan. I just built this PC , and am new to this, are these good temperatures? When i stress tips it goes upto around 70-75 degrees celcius.
  14. My PC amd fx-8320 with h100i cooler upon boot up my bios says all cores are at between 15-17Cm(winter) and my room is around 65F. (American. Don't know C conversion off the top if my head) is that bad? It's a brand new build and runs great so mobo isn't broken. If it's bad email me please I have never used toms hardware forum gearhead443322@gmail.com

    Thank you
  15. my intel i5-3330 @3.0 ghz idles at 37-49 degrees during summer just wondering is that normal?
  16. One thing that should be mentioned with others talking about sub-ambient temperatures being possible. It should be noted that sub-ambient is actually a bad thing for your computer because water droplets will form on your components. We all know what water does to powered electrical devices.

    Just an FYI since the topic was broached.
  17. oh yeah i compleatley forgot about that my computer seems fine and their is no water their, really hot here where i live it was about was 37 yesterday and now it was 39 today way to hot for me and my computer since i dont have good airconditining :bounce:
