Hi!

Recently I noticed my PC being loud since i stopped using headphones. I ran HWMonitor and these were the results

Mind you, these are the results after a good clean and new thermal paste layer - i used arctic silver 5. Yet these temperatures seem really high. Really need help determining a fixing this issue as i believe it's been going on for months and surprised it's lasted this long. Please help any way you can. Thank you.

CPU: i7 4790K 4.0GHz
RAM: 16GB DDR3
GPU: GTX970
Motherboard: ASRock Z97X Killer
Main boot: Intel SSD

  Thanks everyone for the help! Really appreciate it, it's running a lot cooler than before :)

  Hope you have a fun and say holiday season!

  In the windows power settings, advanced, you can set the max CPU usage, under full load, I found dropping the max usage from 100 to 95 had a huge drop in temps, something like 15~20 degrees

    Yes, but doing so also disables your CPU's ability to Turbo so if you take the 4790 as an example:

    https://ark.intel.com/products/80806/Intel-Core-i7-4790-Proc…

    Normal operating clock is 3.6GHZ (3600MHz), with max Turbo to 4GHz as permitted (temps) / required.

    Changing the power setting from 100 to 95 in windows effectively locks the speed to a maximum of 3420MHz at all times, leaving with a slower albeit cooler running CPU.

      Yeah will refrain from adjusting power settings. Mine is 4790k Base clock is 4.0GHz turbo is 4.4GHz don't wanna give that up but thanks for the suggestion xD

        Only other thought, my mums computer was hovering round 90° very often, turned out the cable to the CPU fan was caught in the fan blades. I would check physically, the motherboard wasn't throwing any errors or anything…

    this is currently broken in 17763 for notebooks

  my Asus notebook ran at 103c always, its last 4-5 years never fail.
  but i never left it unattended.

    That straight up sounds like a fire hazard. And I'm guessing you didn't ever use it on your lap?

  +1

  my cpu only gets to 100 degrees when im in ms paint. i hit that shit hard.

  Might need to delid and relid the CPU.
  Some of the older CPUs had the IHS soldered. But newer ones use thermal paste not sure when that happened though, I think they changed around gen 3

    I don't think OP is savvy enough to delid a CPU…

      Not even that - de-lidding a CPU is a very much high risk, moderate reward proposition. I wouldn't recommend anyone actually try it. Best case scenario is you get a few degrees cooler running chip. Worst case is you completely fry it.

  good luck with OC on notebooks if you're going to run latest windows build.
  nfi why you're overclocking if you're running old hardware, in addition to actual purpose of OC.

  if your applications really needed OC, you would've bought a new laptop instead

  power plans are currently broken in current build of windows 17763 - which is why I'm asking why you want to overclock - because you're going to have to make sure Windows is obeying hardware settings
