    Lightbulb Q9300 Temperature on EP45-UD3P (RealTemp, CPUID, CoreTemp)

    Ok this is now officially not making much sense to me. I wanted to start OCing my new machine so I am taking inventory of my stock temperatures and they seem extremely high. I even turned off bios control of the cpu fan and have it running at 100% and disabled EnergySaver.

    I have an intel Q9300 (w/Zalman HSF), as per intel's Thermal Specification the processor can go up to 71.4. Ortho is driving up the temperature to 68 which seems way too much after only 45 minutes.

    Below are my temps (all applications reporting same numbers):
    RealTemp 3.0: 56 56 51 51 (idle to 2%) || 68 68 60 60 (Ortho 45min)

    CPUID: 56 56 51 51 (idle) || 68 68 60 60

    Core Temp 0.99.4
    : 56 56 51 51 (idle) || 68 68 60 60

    Other Temperature Readings:
    EasyTuner6: System 35 || CPU 29

    I am running a Hush NXT Case which is padded and 2 Enermax 120mm fans (1500rpm max) controlled by Aero Cool EasyWatch (which has 3 sensors for temp)

    AeroCool Sensors Reading: 34 CPU || 29 VGA || 28 CASE
    Its rotating my Enermax fans at 1400rpm front and 1100RPM at the rear.

    So am I panicking here? I can't seem to find conclusive answers on what it the correct temperature and what isn't on this chip.

    The core temps are very high.Idle core temps are over 10 degrees higher than mine at 50% o/c.Load temps are at least as high.

    Your ancillary system/case/CPU temp seem fine tho about what you would expect.

    If i was running stock speed i would expect my lowest core temp to be within 10 degrees of main cpu temp at idle (probably within 5 degrees ).

    To me it seems like a heatsink /cpu problem?.Reseat it maybe?
    Try speedfan too for the temps n fan speeds,i find it reads the same as the other 2

    My idle temps at 3.5Ghz(o/c) are 37-43 degrees(on the cores).Cpu temp is reading 27 degrees.
    Unclocked :cpu temp was about the same(ie about 7 degrees above room temperature),the core temps were more like 30-35 from what i remember.

    Don't use Orthos for quad cores, a single isntance only supports a dual core CPU.

    The 71.4C refers to a different way of measuring the CPU temp, the maxium temp that it's important for you it TJMax, which is 100C for your CPU so you're still quite far waway from that.
    Is the 68C load Orthos with the CPU at stock speed? if that's the case then re-seat your CPU cooler, because that temp is way to high for stock.

    nb: I made my suggestion to reseat the cpu hs having checked your realtemp screen shot ,distance to Tj max etc ,including the fact that the cpu was running standard speed/actually below with stepping.
    Youve overclocked before Fc,yes?.

    As I said even if overclocked the temps would be too high tho for idle.

    Yea those temps are high, my Q9300 @ 3.0gzh is idling around 30,34,41,41 and 50,52,50,50 @ 100%. I would try resetting the HS and make sure the surfaces are as clean as possible. Also try some "a-little" Arctic Silver paste.

    Exclamation Re: Q9300 Temperature on EP45-UD3P (RealTemp, CPUID, CoreTemp)

    This is crazy. Someone suggested the my zalman 7000 which I was using to cool this chip was too old. Zalman has a bracket that lets you use the 7000 with this chip so i got considering the HSF was like 50 bucks and is nice copper and the fans is great. Well to eliminate that as the cause I took it off and reapplied Arctic Silver (as per the instructions) and rebooted. Same temperatures being reported. So I took off the Zalman and put the rinky dink intel HSF.

    The intel HSF can't be installed incorrectly. It is a pushpin design and has a circle of thermal compound cut into 3 stripes. You put the HSF down and push your clips in and your set. Can't mess that up. Booted up and after a few same temps as the zalman install so I think the HSF is not the culprit here.

    Also the reason the screen cap earlier wasn't showing 2500mhz was because in the bios I had "C1E" enabled which powers down cores frequency when not in use. Here is a shot with that turned off and my CPU fan running 100% and my core info as well. IN the bios I have auto set for everything cpu voltage wise.





    Others on another board have stated that the readings in RealTemp, CPUID, and CoreTemp are not accurate because intels sensors on these chips varies from chip to chip. But again I have not read anything officially.

    Question how does the motherboard report CPU temperature? I ask because easytuner can be set to throttle the cpu fan based on temperatures (also can be done in bios). If the CPU temperature isn't accurate, then how can manufactures use that in order to control and throttle the cpu fan?

    Nickel, yes the 68 degrees was at stock speeds. When I run Prime95 "blend test" temperature also shoots up to 74 72 72 72. Both programs cause the temperatures to rise pretty much along the same line. Distance to TJMax is 27 28 28 28 using the intel HSF, CPU fan 100% and "C1E" off.

    Could the fact that the cpu voltage in the bios is set to auto also be causing this heat issue? Or are the sensors just reporting the wrong temperature?

    Here is RealTemp screen cap with prime95 running for a few minutes. Temps showing 74 72 72 72 seem to be holding steady running the blend test.

    I have the same problem with my Q9300 and GA-EP45UD3P...

    Coretemp gives me

    • Core0 : 47C
    • Core1 : 42C
    • Core2 : 48C
    • Core3 : 37C

    on idle.


    When I ran Orthos, it worked for about 4sec. and ended.. here's the log..

    If someone can help us, please do.. cause we have the same problem.. I dont know what to believe anymore.. coretemp?realtemp? everest ? BIOS ??? (in Bios..temperature is 24C.. !!!???) I mean.. thats strange..

    PS : if it helps.. My heatsink is a Scythe Mugen.. with Zalman thermal paste..

    ultra, your temps are way lower then mine. I just put a new HSF I am going to take some new readings in a few and post back.

    Just as an FYI I posted this topic over at hardforum, and the people there say that the core temps on our chips don't report accurately especially when near lower limits. According to a few people as the temp gets hotter and starts to reach TJ Max, then the numbers are more realistic. Here is that thread.
