[SOLVED] Why did my pc overheat so bad?

[BlackBateSkull]

It doesn't usually do this but when I ran Prime95 last night to see if my max temps were ok, it turned out they weren't. It did this after a few minutes of running it and before the temps didn't go over 90°C.
I know my case isn't the best for airflow but I have 2 front fans and 1 rear fan on my Aerocool Shard Tempered Glass and mt r5 3600 is being cooled by a Cryorig M9 plus.

What about your ambient temperature? Did it increase? Also I would suggest getting a good cooling setup.

You will need a good ventilated case to handle that setup anyway.

The minium are also in the 75-77C range. Was this monitoring just during the Prime95 run?

What are idle and medium load temps like?

If the cooler is setup properly I'd suggest you need a better cooler.

I reset the temps after starting the run and reaching (what seemed like a max temp)
The idle temp is somewhere in the 40-45 degree range, the medium load (15 chrome tabs, a youtube video, Minecraft open) is about 60-65 degrees.
And yeah, the case is awful in terms of airflow, I'll get something better as soon as I can afford it. I have static pressure-oriented fans so that should ease my issue a bit but I still don't understand why it overheated after a few minutes of running.
I'll check if the ambient temps too after posting this and getting ready to have my pc shut down.
Edit: If the motherboard reportings are anything to go by, my idle temps got lower because my case fans ramped up more. Also, what cooler do you recommend I go for if I'm on a budget? I think I can figure a case out but have no idea in terms of CPU coolers.

Perhaps the CPU cooler has been installed incorrectly? I think that cooler can be tricky to install

I'll check but I'm pretty sure I did it right.

for a low-end cooler and a rather generic low airflow case i would expect similar temperatures to what you are seeing in these scenarios.

to "fix" this issue you would need at the very least much better fans on that cooler and a better case setup.
Cryorig makes some high-end cooling components but that cooler uses some of the cheapest/lowest quality they have available.

I have 2 front fans and 1 rear fan

the make & model of these fans, their airflow, and their air pressure means as much if not more than their placement.
just because blades are spinning doesn't mean they're moving much air.
so you can have almost no cool air coming in and almost no warm air exhausting out.

The case fans I have are the ROG Strix XF 120A's

If you manually set your case, cpu and gpu fans to 100 percent Maximum, what happens then? You may have to tolerate the noise until your budget allows a better cooler and ventilated case.

Yes as I said above, and others have well pointed out, that cooler is not sufficient and the air flow in the case is minimal to cause those kinds of temps at idle and kind of mid-level loads and under heavy load.

It's exactly as JohnBonhamsGhost said, the main point to keep in mind is that merely having fans that turns doens't mean the case is well-ventilated to meet the heat-dissipation needs of the system.

those are decent fans, as in they would work okay in a basic desktop with a well ventilated case.
but not strong enough for a gaming system with minimal airflow.

include your complete system specs with make & model of all components,
your average ambient room temperature,
and the placement of your system (ie; desktop, cabinet, under desk, floor, etc).
