  • N68c-s

    Hi, I was testing my temperature when I saw that the MCP temperature is too hot, I believe that MCP is the northbridge or soutbridge, so I wonder if it's normal warm up so much as to get close to 80 C.

    Sorry for the English, I used the google translator.
    ps: i have a ASRock N68C-S

      In my experience, software often reads some wrong. Currently it tells my my mainboard is 65k degrees celcius warm in most software, but when I check in BIOS its at around 21 as it should be. So if your bios has a build in temp reader, check that.

      If this is really the case that its so warm, you either got heat-stocking cause of wrong mounted fans or the cooler on that part isn't mounted properly/gone lose in transport

        My N650SLI-DS4 motherboard uses the Nvidia chipset and MCP refers to the southbridge chip.
        The heatsink on for the MCP might not be secure or you might have restricted airflow around the heatsink if you are using the flat ribbon cables for your hard drive, optical drive or floppy drive.

        What brand/model is your computer case?
        What is the brand/model of the cpu heatsink/cooler?
        How many case fans are in your computer case?
        What are the fan sizes and fan speeds?
        What is the temperature in the room where you have your computer?

        Can you post a picture of the inside of your computer case?

          I have a:

          Cooler Master Elite 335, with: Cooler 120mm Front, Cooler 120mm Rear.
          Cooler CPU: Cooler Master Hyper TX3 Dual Fan
          Processor: Phenom X4 9850 125W TDP
          Memory: 2X2GB DDR2 800
          HD: 500GB 7200RPM
          Motherboard: Asrock N68C-S
          Font: C3 Tech 350WR
          Video card: Nvdia GT430 1GB

          This temperature would not be normal for a chipset that uses Southbridge and Northbridge together?

            In your bios, check the "system" or MCP temperature.
            When in windows, only use one temperature monitoring application at a time.
            Download and see what HWMonitor or other applications report for temperatures.
            Unless you have a serious air flow problem in your case, normal system/mcp should probably be less than about 30 - 40o (C).

              My bios does not show this temperature.

              This temperature would not be normal for a chipset that uses Southbridge and Northbridge together????

                I don't know of any chipsets that have a "single" Northbridge/Southbridge combination setup.
                Some AMD setups have an integrated memory controller in the cpu.
                Do a web search using: amd chipset block diagram
                and look at the chipset block diagram image for your specific chipset.
       has articles that cover chipsets, but their website has been up and down recently.

                You need to confirm if other software monitoring programs report the same high MCP temperature.

                  I tested in Aida (Everest) and HWMonitor, that I believe are reliable programs.

                    If the southbridge is really at 80o (C), the heatsink will too hot to touch briefly.
                    If the temperature is less than 50o (C), it will be warm to the touch.
                    Your motherboard might have a faulty sensor, or the high temperature reading might be a known issue and a newer bios version might fix the temperature reading.

                    You might need to contact ASRock tech support directly by using the support section of their website.

                      I already did the test, I put and takes about 1 second to feel much pain in the finger.

                        It looks like the southbridge heatsink uses push pins for mounting it to the motherboard.
                        You might be able to improve cooling the chip where you:
                        1. remove the heatsink
                        2. clean the old thermal interface material (TIM) using 91% pure rubbing alcoho
                        3. apply a small thin layer of tim to the top of the chip
                        4. reinstall the heatsink
                        Another option is to install an 80mm cooling fan to blow air across the top of the heatsink.
                        Your English is fine

                          Re: N68c-s

                          I am afraid to change the chipset, so I was thinking of buying a 80mm or 90mm fan and install on the side of the case, would be cooler on the chipset, but with a distance.
                          Does it help ?

                            I'm glad that google translator can make sense of my posts

                            Check out, posts #81 and #83, where I installed a 92mm cooling fan for my graphics card. I used plastic cable ties to secure the fan. I think that the best heatsink cooling will be with the fan very close to the heatsink. A cooling fan installed on the side of the case might work well if you use a cardboard tube as a fan shroud to focus the airflow dircectly to the heatsink.
                            I am afraid to change the chipset
                            You wouldn't be replacing the chip, you would be removing the heatsink only, cleaning both parts and then applying new TIM. You might have to remove the motherboard from the computer case to remove the heatsink and apply new TIM. This should be somewhat easier than applying TIM to your cpu.

                              don't know when you have bought it, if there is still warranty, returning it for an exchange might be an option if you don't want to mess with it yourself
