So let's get right to the issue. I start up my computer, load windows - everything is fine and smooth. Doesn't matter what I play, it could be Skyrim or Minecraft. The game runs fine for around 10 minutes with proper FPS. Then it suddenly drops to 1 - 20 FPS and stays there for the entirety of my gameplay. I quit the game and whole computer is laggy for certain period of time (until it cools I suppose).

In summer FPS drops much sooner. I played in winter, it was cold outside and my FPS dropped. So what I did is I opend the window to let the cold air into my room and the computer was fine the entire time. So from this information I assumed I have cooling issues but CPU temperatue stays below 50°C as well as GPU. And I even swapped fan CPU cooler for a water one - didn't work.

I don't have means to try and swap out all components one by one to detect the bad one.
Ask me anything and thank you for your answers.
 
For cooling the CPU surrounding components, install a fan with a top-down blowing design. A case with a place for a fan on the side accomplishes that. Use a case with high airflow. The motherboard is a not a high end model. You can tell by lack of heatsinks on the CPU surrounding components.

RE: Calvin7

So you think its the CPU cooling issue? I had a fan with top-down blowing design before and this issue was the same so i swapped it for water cooling. I have also fan installed above PSU right next to the mother board with CPU. I can post a picture.

The big fan on the left is from the cooler and i have an aditional one on the PSU below. Though I have only one fan sucking the air inside. So i have one more place to install sucking fan. Do you think that will solve it? or shoud i change the whole case and change water cooling for top-down fan
