    Over Heating Issue please help.


      okay so first my rig.


      Mainboard : Gigabyte Z68A-D3H-B3
      Chipset : Intel Z68
      Processor : Intel Core i7 2600K @ 3400MHz
      Physical Memory : 8192MB (4 x 2048 DDR3-SDRAM )
      Video Card : NVIDIA GeForce GTX 550 Ti
      Hard Disk : Western Digital WD10EADS-00L5B1 ATA Device (1000GB)
      Hard Disk : Western Digital WD10EARX-00N0YB0 ATA Device (1000GB)
      DVD-Rom Drive : _NEC DVD+-RW ND-3650A
      Monitor Type : Acer X223W - 22 inches
      Network Card : Realtek Semiconductor RTL8168/8111 PCIe Gigabit Ethernet Adapter
      Operating System : Windows 7 Ultimate Professional Media Center 6.01.7600 (64-bit)
      DirectX : Version 11.00



      I have not overclocked at all.


      In the bios on boot up it says it is 87 degrees.


      In windows idle it is 45-50celsius


      Prime 95 full load it gets up to 98 celsius.


      While playing BF3 it gets up to 90-95 celsius.


      What is the issue?  It is a brand new CPU.


      Local computer hardware store owner told me that it sounds like i got a bad CPU that something like thermal paste even if i had absolutely none on there would only make about a 5 degree difference.  He was convinced that newegg sold me a recall they sell as new.  IDK.  Maybe that was just his way of trying to get me to buy from him.  I want to know what the issue is and what ways I can go about fixing it.  From what I have read around the web I shouldnt be above 80 celsius even on a full load via prime95.


      btw I have stock cooling and w/e thermal paste it had on it when it came out of the box.  I still dont believe intel stock stuff would be this bad cooling wise.  Any ideas anyone?

          The thermal specification (TCase) of the Intel® Core™ i7 processor I7- 2600K is 72.6°C: http://ark.intel.com/products/52214/Intel-Core-i7-2600K-Processor-(8M-Cache-up-to-3_80-GHz)


          This a number established by Intel® as a point of reference in order to understand what could be expected as per normal processor temperature.


          Anything from the Tcase and below will be the expected temperature of the processor in normal use, anything that doesn't stress out the processor (watching movies, burning CDs, browsing the internet, creating documents, etc.) When the processor is stressed out meaning that you are running heavy processor applications that take control of the CPU or uses it at 100% the temperature will go beyond the Tcase. It can perfectly reach 90 to 95 degrees and the processor will still be OK. The cooling fan is in charge to keep that temperature there.


          If the processor temperature reaches 100 degrees or more it will send a signal to the motherboard to shut down to prevent mayor damages and most likely it won't be possible to turn the computer back in until it cools down.


          When accessing the BIOS, the thermal control features are disabled and due to this, the processor’s temperatures raise and are usually higher than within the Operating System where the thermal control features are enabled.


          Furthermore, we do not validate third party software testing results since, it is very common for them not to be fully optimized for the specific processor model in use (these tools are more generic), being very common for them to provide inaccurate results.


          If you would like to test your processor’s functionality, we recommend you running the Intel® Processor Diagnostic Tool which can be found here: http://www.intel.com/support/processors/sb/CS-031726.htm


          According to the system behavior description presented, the processor is currently running within specifications.

            Just to echo the good advice from Intel that although these temperatures seem rather alarming to us, it's not very hot when you are a piece of silicon.


            The typical retail cooling solution is designed for real-world use which very rarely sees all cores driven to the maximum, so when you run something like Prime you can overheat a perfectly good setup. Modern CPUs are designed for this and if driven too hot will automatically take precautions to slow themselves down to avoid damage.  In order to allow stress tests like Prime to work without causing alarming temperatures Intel would need to ship much bigger heatsink solutions, which for 99.99% of the people is a waste of money and metal.


            Temperatures in the 80s and 90s are quite normal when modern CPUs are understress.

              and 50-55 celsius while idle sometimes is good too?  Thing shoots up to 95-97 celsius when I open league of legends and browse the internet at the same time.  From what I have heard from other people it sounds like the heatsink isnt touching properly.  because even thought its hitting 97 celsius the heatsink itself is cool and not warm or hot.  So for the next couple days I am gonna use my gaming rig to just browse the net.  I ordered and aftermarket HSF the CM 212+.  make sure I have proper contact when I install it this time.

                What cooling sulition are you using now , Air or H2O , I would sugest looking at some of the H2O Products that cousair makes , I have two High end machines , that I just could not get the temps that I was looking for and I installed coursair H2O sys in both , they have been running at 40C  for over a year now , temp never goes above 55C no matter what I throw at it .
