I know this question was asked a million times before but i couldn't find a specific answer for my question.
I am using a intel quad core q9500 on a lenovo l-ig41m motherboard and non-80+ certified psu and also a PNY GTX 670 GPU.
My cpu hits 70-90c within a few minutes of 4k youtube video which is super high temps for such a simple action.
What could cause my cpu to get so hot?
I did checked for an answer before i am not here to waste no ones time i am having a real problem and i really cant find a solution.

Thanks in advanced, Afik.

If you are using the stock HSF, the plastic likely warped over time and the heatsink has come loose. In that case, you will need to install an aftermarket HSF.

I had to replace my E8400's stock HSF for this reason 7-8 years ago, re-applying paste can't do anything about the plastic frame becoming loose.

Not necessarily: on a GPU with hardware acceleration, 4k decode can have negligible impact on CPU usage. On my i5-3470 and GTX1050, MPC show 2-3% CPU usage playing 4k samples. The GPU is doing practically everything.

Considering the age of that platform, the thermal paste may be old and dry. I would try applying new thermal paste to drop temps.
Here is some cheap paste:

Also, what cooler do you have?
4k Video streaming is mainly network and GPU demanding, however, will stress the CPU a bit more than 1080p video.

Thanks for the quick replies, i will try to replace the thermal compound.
I dont know the exact model of the coolor but it is not intel stock cooler it's says "deep cool" on it but no model number or anything.

Yep. The CPU is an old model and the Nvidia card does not support hw acceleration. Only 1050+ Pascal models are supported for 4k (Netflix) playback. https://nvidia.custhelp.com/app/answers/detail/a_id/4583/~/4k-uhd-netflix-content-on-nvidia-gpus

YouTube 4k vp9 is barely supported yet on any gfx cards over a couple years old, so is also cpu bound according to articles online.

  1. Old CPU.
  2. Old, worn, inefficient cooling system.
  3. Quick search Intel doesn't even list a iGPU for this q9500, so no iGPU, no eGPU, this puppy maybe playing video via software which takes lots of CPU cycle (high load). What is the CPU load when playing these 4K then? that will give you the clue. My 5 years old i5 Haswell with iCPU's load hardly moves when playing 4K and sits at 35c.

Can you take a picture of the cooler and show it here? I doubt the cooler has gone bad since its not stock, likely the paste has dried up.

Hay, here is a picture of the coolor :

Hay, thanks for replying.
By cpu load do you mean clock or by percentage?

Whe you apply new paste to the cpu i would use compressed air to blow some of the dust out of the cooler. That cooler shouldnt really go bad since its just some metel with a fan on it. The fan spins correct?

Ofcurse the fan spins.
Another thing is that i know for sure that the thermal paste is not old it's mabey a year old but this thermal paste came in a weird little bag so if the type of the thermal paste could affect it so mabey its the problem, it didnt looked like high quality thermal paste.

After so many years, it is time to replace the grease and clean the dust of the cooler.
Adding case fans can outflow the heat from case. GTX670 can make a lot of heat.
