Motherboard and CPU at Very High Temperatures

Hello,

Lately I've noticed my fans in my computer have been running a lot harder than usual. I opened my computer up, grabbed a can of compressed air and cleaned out as much dust as I could. I was hoping that this would have fixed my issue, but it continued to persist.

I decided to download Speccy to monitor my computer's temperature levels while I was idle, playing games, or watching youtube or doing miscellaneous activities. While being idle the temperature of my CPU was around 30 - 45 degrees Celsius, my motherboard stayed around 35 - 45 degrees Celsius and my GPU was at a steady 54 degrees. When I would play games, my CPU would often be 80+ degrees sometimes going over 90 degrees. My Motherboard would be the same. It seems more frequent now that they peak past 90 and would simmer to about 85 - 89 degrees. My GPU would be around 50 - 65 degrees.

I'm fairly new to computers, my friend and I built mine together about 2 years ago. I have been thinking that perhaps there's an issue with the thermal paste, but then again, what do I know? After monitoring my computer for about 2 weeks and accumulating a lot stress and anxiety I asked him what I should do. He suggested that I come onto this website and ask about it. This may not seem like such an issue to many who read this post, but since this is my first time experiencing this thing I feel like the world is crashing down around me and reality is going to shatter. I know that's a big exaggeration, but I have beginner's anxiety. If anyone has any idea on how to help me and possibly solve this problem (I don't know if it is one to be honest) I'd greatly appreciate it!

I'll leave my system specs down below:

While you are checking out thermal paste, etc. look very closely at the fins of the heatsink on your CPU. I have seen photos of units in which the air flow spaces between the metal fins are completely packed with dust, so firmly that blowing air just won't get it out., So, no cooling, right? If your have lots of dust, ensure everything is off then try to push it out with a small thin probe or stick or maybe small screwdriver. Loosen and blow until clean.

ALSO, check the condition of all the foam dust filters placed in front of your intake fans to be sure they allow sir to flow into your case.

Not to worry, you said that you and your friend built your PC 2 years ago? have you tried changing the thermal paste for your CPU? that should fix your problem. if you're still having problems AFTER changing thermal paste (change your thermal paste FIRST, 2 years of not changing thermal paste is bad and no harm in doing so.) try undervolting your CPU. it can drastically lower your temperatures.
