This is only a recent issue and it doesn't happen with any other game, but whenever I open Minecraft my fans just start blowing so hard. and it really confuses me cause I run games like doom eternal and warzone great. I don't know if its optifine, or shaders but ive turned those off and that doesnt really help the issue much. I don't remember my exact CPU but my system is
The Meaning of Life, the Universe, and Everything.

Those are decent specs, so you'd assume you'd get some heat. Minecraft is a poorly coded game (for the most part).
I'd suggest getting some canned air or similar, and cleaning out as much dust from your PC case as possible. Dust creates a lot of heat, which the computer tries to combat with making the fans go faster. (Remember to hold down the fans so that the compressed air does not spin them fast, as DC motors (the kind in PC fans) can both receive electrical current, and spin; but they can also spin, and give electrical current back into your computer - which could possibly cause damage)
Also try tuning down the graphics settings as much as you're comfortable with doing.

I have a poorly ventilated HP laptop, so it gets very hot doing pretty much anything, especially playing Minecraft. That game isn't the most efficient when it comes to CPU/GPU usage, so any computer with get a little toasty playing it. I have a cooling pad (just a thing with fans in it) that I keep my laptop in, so if you're also using a laptop that would be helpful. Also, like toydotgame suggested, cleaning all the dust/pet hair/lint/etc out of the computer helps a ton. If you have a desktop, maybe try getting another fan or cooling system. That might keep your main fan from working too hard.

Adding on to that idea, you can also just add some empty space under your computer. My laptop takes in air from the bottom and pushes it out the back. Putting it on a table with the feet it's got only gives it ~2 mm of space for air to enter underneath. I bought a set of 4 rubber feet which are about 6 mm tall and put it on the corners, which gives me space.
That gives me a lot better cooling. If you're using a laptop, you can use anything - coins, dice, etc.

If you have not already you should limit the frame rate to your monitor's refresh rate, either with Vsync or the framerate limiter - I have lower specs and my computer is basically idling when playing, as expected given that I can exceed 1000 FPS unlimited but Vsync limits it to 75 FPS (I can feel the fans speed up if I let it run unlimited; otherwise, the GPU fan never runs at all and it only runs at 150-300 MHz clocks). Of course, this is with my own modded version which is far more lightweight than modern versions which use way more resources than necessary (they are more multithreaded to help offset this but this makes it more important to set a limit as overall CPU utilization across all cores can be higher); a lower render distance also helps since the game has to render up to 4 times more stuff with each doubling (of course, if you have stuff like big mob farms or storage rooms they can still place a major load on rendering in a small area; my main base which has 500+ chests/signs/entities drops unlimited FPS by 3-fold, worse than going to 2x the render distance (using barrels instead of chests can help a lot); and if you are using mods many of them overuse tile entity renderers or are just poorly coded with a consequent performance impact).

Idk could someone help with this?

TheMasterCaver's First World - possibly the most caved-out world in Minecraft history - includes world download.
TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4.
Why do I still play in 1.6.4?
since it's summer in the northern hemisphere it may also help to get a fan to help circulate the air in the room.
I do agree with the previous comments people made about limiting the frame rate
but ambient temp is just as important, because a lower ambient temp means your device can cool itself much more efficiently.
And if possible use blinds in your gaming room to keep sunlight out,
unless you're using a solar panel sunlight is quite possibly the worst thing to expose to electronics,
and it's the reason I don't have my computers too close to my window.
