  • CPU Temperature brain storming

    So, I've got an AMD 7850K and a Cooler Master 212 Hyper Evo for the cooler. For sake of discussion I'm running windows 7, since the sensors on my Gigabyte's sensors aren't supported by lm_sensors.

    Over the last few days I've reseated, wiped clean, reapplied the thermal paste (cheap dynex stuff I got a few years ago-- its what I had on hand, and the cooler master stock stuff they send with the cooler. Arctic Silver 5 is on order) and 'rinsed and repeated' probably... 6 times? When I first built this computer a couple months ago I was idling at around 34-35 at BIOS, now I'm idling at 45 and sitting at the windows 7 desktop has me going up to 59-60. Gaming? Temps hit 70+.

    Ambient temperature is 26 degrees. All the fans are on and working perfectly fine.

    The amount of thermal paste is somewhere between a 'grain of rice' and 'a pea,' and the CPU is NOT overclocked, though the ram is set to 2133. BIOS has been reset to 'optimized defaults.'

    Anyone got ideas? Its a brand new build and I'd rather not have something fry.

        The CPU? ---> AMD 7850k
        The Cooler? ---> Cooler Master 212 Hyper Evo
        The case? ---> Corsair 350D

            The max temps for the APU's are a bit higher (72.4 for your model: http://products.amd.com/en-us/Deskto...il.aspx?id=100 )

            AS5 should help. What are you using to clean the old stuff?

            Also, double check voltage settings. I had an Asus board that put an extra 0.05V on top of the CPU's default voltage (stupid design).

              On the CPU I'm just wiping it clean with some tissues, on the Cooler ive been using a slightly damp cloth to wipe it clean and then following it up with a microfiber towel to dry it and get up any left overs.

              Vcore Voltage = ~1.308V
              DRRAM Voltae = ~1.656V (Ram is manufactured to run at 2133mhz)

              I will say that RIGHT NOW, BIOS is showing my CPU temp as being 41C-- so at least its doing a little better. The system temp is sitting at 32C . Its also cooler in the house now than when I made this thread... could this just be an issue of ambient temperature? When I put this together it was February or March, so early spring for me.

                  I've always used rubbing alcohol (70% works, but 90 is preferred) and cotton balls...

                      A pea sized can sometimes be a bit larger than some think... You don't want anywhere near excessive when it comes to thermal paste... if anything, you want less than more, from my experience as the more you overdo it, the more the temperature rises.

                      Also, thermal paste or different thermal pastes really don't make that big of a difference. It's only you when you do something extraordinarily stupid like cake the stuff on there or put none at all (which some people actually do...). Just make sure it's a very thin layer of thermal paste... use alcohol of a high percentage to clean... and place heatsink straight onto CPU (try not to fidget too much).

                        I had some abnormally hot temps the first time I stuck my 212 evo in my system. Turns out I didn't use enough thermal paste. If it seems too hot, take off the heat sink and make sure the thermal paste is spread evenly. Also tighten the heat sink in an diagonal pattern to get all the screws level with each other.

                          you can drop the cpu voltage to 1.2
                          also turn off overdrive crap

                          the gpu still should use more power


                          bdw i got a 212 evo on a 125W cpu (not apu)
                          it's great, rarely goes over minimum 600rpm

                          PS sensor could be wrong, try touching it (i doubt it is thou)

                            Barely over 600rpm? Geez, mine is at 1440 rpm right now. What CPU do you have? Also, do you have the stock fan?

                              Okay so the Arctic Silver 5 dropped the temps a few degree, much closer to what it was before. I can't pull up the exact temps right now since a couple days after the AS5 came in, I had to RMA the RAM because the one stick was throwing errors. Still not where it was at originally, but for this moment its doing better..
