  • i7700k Issues

    Hi guys,

    I recently bought a i7700k coupled with Asus new ROG micro atx motherboard. It's cooled by a Coolermaster 115i. I am getting heat and fan spikes for almost every task I give it. I open a browser - woooosh, I open a new tab - woooosh, I open click a link - wooosh. You get the idea. I am no rookie to building PC's, I have the correct amount of thermal paste, I have very good fan setup inside the tower (Corsair 500D) and I do not have the CPU overclocked at all. Any reccomendations or infomation on this issue is greatly appreciated. Could I have a bad chip? Or is there something I could change in the bios?

    Thanks in advance,
    slim

    Check the CPU temperature, and configure your fan curve in the UEFI.

      it could be the fan curve is too aggressive for your taste, or it could be the chip is just hot?

      last few gen have ran warmer and warmer :/

      use something like hwmon to keep an eye on your temps and volts so you know what is going on

        Not to mention Intel CPU's usually spike with temperatures going from 35C to 50C in a second, so adjusting the fan curve as mentioned above might work well for you as doing even the most trivial thing will increase the temps a little.

        AMD CPU's (or at least older ones i've used) increase temps gradually so you'll see it climb 35, 38, 40, 42, 45, 48, 50 etc. So the fore mentioned issue wouldn't normally come up.

          The temperatures do go up drastically on Intel CPUs, yeah... you're not wrong there.

          My rig (below) is set to stay on 0% until 50c, but that puts the fans into their lowest RPM range possible as they don't support a 0 RPM mode. After that, they come up to 20% at 55c, 30% at 70c and 100% at 80c. I've not seen my rig go above 65c under Prime with AVX yet... silent computing is bliss. <3

            Hmm.. I have changed the curve and it does seem to help somewhat - thanks for that. The chip is operating at 38-57 degrees with menial tasks tested with core temp. Obviousy it spikes every time the cpu multiplier jumps up. Should I be worried or have I just got a fast cpu and a small fan heater all in one machine?

              As long as you aren't bothered about power usage, you could turn speed-step off in the bios and let the CPU run at full tilt all the time and then adjust your fan curve that way? It should be easier to manage the temps that way as its not boosting and increasing voltage all the time, idle temps will be a little higher but it might be easier to cope with as they shouldn't surge quite so high.

                Thanks for the help Ian, I will try it. What sort temperature should I not be exceeding when playing games (RL, LoL, KSP nothing too strenuous)?

                  Check that heat sink compound has been applied correctly - more is NOT better.

                    Given that it isn't overclocked and not de-lidded, I'd expect temps in the low 50s all the way through the high 60s during gaming loads. It's nothing to worry about as they're fine at until about 100c.

                      Thanks Burn. Yeah I did say in my original post, I'm fairly competent at building a PC, and I know how much thermal paste to use - Never the less I did reapply before I asked the forums for help!

                        My 7700k does the same thing, watching the temps in coretemp all 4 cores are constantly going from 30s to 50s up and down alll the time. Some cores say 50 and some say 30 or 40.. looked into it seems the norm, coming from an AMD 8 core where all the cores seemed to show the same temperature it was a little worrying but as long as cooling is good (mine is) im not too worried.

                          67k acts the same. the internal heats a fraction before the heat spreader kicks in.
