I recently bought a brand new PC and I am very new to Desktop and don’t really understand fundamentals and specifications as of right now, but I will put the specs lower in the post here. Its idle temperature when I first got it (three months ago) was roughly 32° Celsius, or about 89.6° Fahrenheit according to MSI Afterburner. Over the past several weeks, my pc has been raising in temperature with its idle state, not having many programs running in the background. When I ran games like Escape from Tarkov, it would run perfectly fine sitting around 55°c (131°F) or Helldivers II at about 57°c.

As of right now, the idle running temperature is at 39°c (104°F) and Helldivers II now runs at 60-75°c (140-167°F).

Could someone tell me why there is a sudden increase of temperature, what happened and potentially give some advice on how to run it cooler? Thank you for taking the time to read!
