How to lower cpu temp?
I have constantly 85C on my cpu while playing BG3 in Act 1. I'm afraid what will happen when I'll get into a big city. I've already lowered some graphic settings, DLSS is off, but it didn't help much. Is there any graphic settings I can lower/turn off to take off some cpu usage? My specs are: Rtx2060 super, i5-9400F, 16GB ram.

It's possible that you might not have total coverage with the current paste and this is resulting in an unusual hotspot on your CPU.

Part of your response did confuse me though, as a "stock cooler" and a "radiator" are not the same thing. "radiator" implies water cooling where a pump cycles water between a thermal plate on your CPU and a radiator with fans on it. So there would be 2 obvious hoses for water connected to your CPU. If you don't have water cooling, I would advise at least getting a cheap cooling tower with 2 fans on it.

Case fans don't matter much for CPU cooling if it's water cooled, but cooler air in the case does matter for keeping the motherboard, ram, and video card cool. I would advise at least 2 intake fans and 2 exhaust fans. The easiest way to know if a fan is intake or exhaust is that the air always blows towards the spokes that connect the center of the fan to its outer wall.
If you are going to have an uneven number of fans blowing air in and out of the case, you want more blowing air in (as that will create a positive pressure in the case and reduce dust accumulation). such as 3 intake and 2 exhaust.

Overall it sounds like you need more fans regardless. Having only one case fan and 1 CPU fan is a recipe for overheat.

Maybe check if you have a decent air flow. I don't think it's the hardware itself, it's a cooling problem.

Limit your FPS.

Many of us witness the sudden spikes in CPU temperature, even with better cooling, the spikes are still there. My CPU always runs below 60C but in this game it occasionally goes above 70C. Please don't tell me its still safe that I don't know it well, I just don't like it happening in just one single scenario.

Uhm. Your CPU going over 70C isn't really a problem. That's regular working temp under full load for air cooled CPUs.
85C, like OP has, is indeed a problem.

That's why I say the game is running hotter than most usual usages. If anyone needs a better cooling just for this game, it is not justified enough. This isn't even any AAA graphical fps masterpiece.

Graphics have little to do with CPU temp.

I tried to say fps, with high fps, but I didn't bother to list them all out. What's with you? You guys always like going off track, right?

This.

Best done in your graphic card control app.

60 FPS looks fine to me and limits how often my cpu fan kicks up to fast.

MSi after burner,and turn fans WAY up

Need a bit more information to diagnose.

1. Game settings? Resolution, frame rate cap, etc.
2. Is your CPU overclocked? Some systems (especially pre-built) will come with overclocking already set up.
3. Thermal paste type? Did you put it on yourself?
4. What cooling unit is used for the CPU? Cooling tower or Radiator? How many fans on it?
5. What is your case fan arrangement? How many fans blowing air in and now many blowing air out. Where is each one located (ex, 3 intake on front, 2 exhaust on top and 1 in back)?
6. Have you adjusted advanced power settings in windows?

A quick and dirty solution to reduce temps till you find the source of the problem is:
Control panel>
Power Options>
Change Plan Settings>
Change Advanced Power Settings>
Processor Power Management>
Maximum Processor State 99%

That will prevent your processor from maxing out or overclocking. It's a method more commonly used in gaming laptops as they tend to run very hot and don't have many heat solutions available. But your CPU indicates you are using a desktop and there are a lot of heat solutions for that.

Check your cooling and air flow. Is there any dust clogging up fans? Any way to reduce the room temp? If it's been a while since the CPU has been installed, it might be time for a fresh application of thermal paste (it does dry out overtime). Consider going with a 3rd party cooling solution if you have a stock Intel fan. You can get an AIO liquid cooler for cheap and it can make a huge difference.

turn off turbo boost in bios or increase ur cpu fan speed or buy a better cooler or get better air flow (open a panel) or double check ur coolers paste and connection

CPUs run warm these days especially in a laptop

The CPU indicated is a desktop CPU and a "constant" 85 is not good. More acceptable if it was a laptop, as laptop components are generally more heat resilient, but still not good for a constant.

1. Well I can't check now my graphic settings now. I have for sure 60 fps cap, 1080 resolution, DLLs off I don't remember the others, I was setting them by myself and most of them are medium/high.
2.As far as I know my CPU isn't over locked.
3. I have this PC for 4 years and I was changing my thermal paste myself 2 years ago, it was my first time and I followed some guides but I'm not sure if I did it well. I don't remember exactly what was this paste, I only know that it was Grizzly.
4. I have stock cooler so only radiator and one fan, nothing more.
5. I didn't adjust advanced power settings.

I have desktop. Maybe I should clear my cooler and change thermal paste, and I will do it for sure in near future but idk if that's the case, cause I don't have such temps in the other games with heavy graphics like Total War: Warhammer etc. So I thought there is some graphics setting in BG3 that causes such CPU temp.
