    CPU High Temp

    eTron

      Hi all.  Just completed a new build with P8H67-M  EVO and Core i7 2600K using stock Intel Heatsink/Fan included with  processor.  Other details probably don't matter, but it is in an Antec  Mini P180 case with a Seasonic X-560 (Gold) PS, has 8GB G.Skill Rip Jaws  RAM (2x4GB), a Seagate harddrive (SATA) and ASUS DVD Writer (SATA).

       

      After  carefully completing the build, I turned on power for the first time,  and it powered right up and gave me the BIOS screen.  In the BIOS, the  CPU temperature shows as 63C-64C at idle!  In my opinion this is much  too high!  I've never seen idle temps this high in any previous builds.

       

      Can anyone suggest any reasons and/or solutions?

          Hello,

          Is a good practice to keep an eye on system temperatures, it will prevent computer problem. Now Those readings are normal for a i7-2600K as the threshold Temperature for it is 72.6°C even though  we can see 2 or 3 more °C degrees beyond that specifications when running heavy loads (like gamming and video rendering).

          Best regards.

            Hi Ricardo,

             

            Thanks so much for the reply.  I will install Windows and see how the temperatures are then.

              IN your ASUS BIOS you can turn up the CPU fan and bring down those temps on the CPU.

                The new ASUS mother boards for Sandy Bridge CPUs are notorious for having rather high CPU temperatures when you are in the UEFI (I have one.)  There is a FAQ post in the ASUS forums about this, which states the CPU temperature will be up to 20C higher than normal when in the UEFI.  Why this happens is not entirely clear, but it seems the new UEFI "BIOS" puts a high load on the CPU.  When in the UEFI, none of the CPU power saving options such as EIST or C-States are active, so the CPU is running at it's standard frequency constantly, and the CPU voltage stays at about 1.2V.  Next, the CPU and chassis fan speed control software is not active when in the UEFI, and the fans run at or near their full speed.  Given that, it is even more strange that the CPU temperature is that high, but it is.  I wonder if that reading is actually correct.

                 

                So, the CPU temp you see in the UEFI is normal for your board given the information I have seen and my personal experience with a board similar to yours.  I don't use the stock Intel CPU cooler, and my temps are lower than yours.  Everything is probably fine, just check the temps after booting into Windows.  If you use the ASUS temperature monitoring program, do not run any other programs like that (Real Temp, etc) at the same time, as the ASUS program gets bad data when that is done, and you'll see overheating warnings or very strange temperature readings that are simply wrong.

                  I don't have the reasons but this could be a solution (http://www.theregister.co.uk/2009/05/11/koolance/).

                    Boyett , you are realy tring to put these people in the deep freeze ??   Or you just having fun ??

                      Not really. I think it is a better solution to their problem.

                        Oh yes, I agree.  I use one of those liquid nitrogen cups, but when a mother board is mounted in a standard PC case, I find that the LN spills out of the cup.  That does help chill the video card, so not a total loss.  Where do you guys get your liquid nitrogen from?

                            Flashed BIOS to 1850 (the latest for this board at this time), installed Windows 7 Pro  64-bit and all drivers.  Haven't installed any monitoring software yet,  as I've been struggling with Windows 7 networking, trying to get it to  play nicely with XP machines.

                             

                            Prefer to use the same software  across all machines, and have been using SpeedFan on all the other  machines for monitoring, but someone elsewhere mentioned CPU-Z, and parsec mentioned Real Temp (which I haven't heard of).  Any thoughts on  which may be the better choice, and why?  [At this point, I haven't even  checked to see if any or all of them will run 64-bit and handle  this particular mainboard.]

                              It really doesn't make much difference which monitoring program you use, mostly which UI you prefer.  They all run on 64bit platforms, or have a version for 64 bit machines, that is nothing new and not an issue.  Personally, I like HWiNFO, which works great with my ASUS P67 board.  I mentioned RealTemp since it is popular but I don't use it personally.

                               

                              If your mother board (ASUS?) includes AI Suite II as a monitor, it was pretty good but after a UEFI update, they ruined it.  They changed the sensors used for CPU temperature from the on-CPU ones, to apparently ones mounted on or near the CPU socket.  I noticed this when after a UEFI update, my CPU temperature at idle was dipping below ambient temperature.  Yes, below room temperature, consistently and repeatedly.  This was on a high performance CPU cooler, but it is impossible to cool a CPU below ambient with an air or liquid cooler (no I don't use liquid nitrogen.)  Why they did this is beyond me, possibly to stop the questions and complaints about the high CPU temps in the UEFI/BIOS.  I contacted them about this but was ignored, so I simply don't use the temp monitoring feature in AI Suite II.

                               

                              This does not affect other temperature monitoring programs, so use what you prefer.  I think I recall that I thought RealTemp's temperatures were a few degrees lower than other monitoring programs, although that could have been SpeedFan, and I may have been mistaken.  Some users prefer seeing the lower temps, but I prefer reality.  This does  demonstrate the reality of these programs, they can be adjusted to display anything the programmer (managment) desires.  The vast majority of these programs are honest IMO, but there can be exceptions.

                                really?

                                 

                                Well, just as really as your other statement:

                                  Thanks for the info, parsec.  I will try a few (coretemp, hwmonitor, realtemp, speedfan, maybe others if I come across them) and see which I like best.  Will report temps.

                                    The statement in bold above is my answer to Roberts statement " Boyett , you are realy tring to put these people in the deep freeze ??   Or you just having fun ??"

                                    The "really?" question refers to your statement "I use one of those liquid nitrogen cups, but when a mother board is mounted in a standard PC case, I find that the LN spills out of the cup."
