How to Underclock my GPU/reduce preformance?

[Mr.Stork]

I have 1660ti (pretty much locked gpu). I've watched some yt videos, they said reduce core voltage slider, but it doesn't go below 0, to minus figures. Core clock and memory clock went in the minus, but I didn't see any reduction in performance(no less fps). Though, I don't want to harm my gpu. Please help, there are reasons I want to reduce performance.
Thanks!

Could you elaborate? There might be a better solution.

Yep, I live in a hot place, so my room gets too hot from the heat of the gpu, so I wanna reduce the fps, I don't need so much fps anyway.

bad PSU I suppose?

Just drop the power slider, that can go way below 100%

If you enable vsync and lock your fps to 60hz the GPU will work a lot less.

nope, heat. and dont ask about my airflow, no space it's tucked in a corner, no space. Just please tell me what I asked kindly.

Open MSI afterburner, and move the power slider to below 100%. The smaller the power %, the less power the gpu can use. For example if you put it at 50%, then the gpu will output 2x less heat, as it is using 2x less power.

Ik that, I did, case dosent get airflow that well. just....

like this ?

Well yes, now click the little arrow button to confirm the changes. 

 

Now your gpu uses 42% less power, and so it should output 42% less heat.

I see, so the fps will be lower I suppose? how low?

Well simple math would say that your FPS would be 42% lower, but that is not the case, as Nvidia gpus are actually more efficient at lower power draws. 
i just recommend you to test it!

My guess would be that the fps would be 25-30% lower at 42% less power.

MY god, tysm, you're the first one who actually helped me, instead of advising me about my pc, which is good, but I got the answer that needed. Thanks!

Maybe v-sync "drop" the fps be it is quite power hungry

What?

Do you mean "but"?

vsync is not power hungry, the GPU usage drops a lot when vsync is enabled, and lower usage = lower power consumption.

Afterburner is fine for setting voltages&power targets.

 

For voltage-frequency curve, press CTRL+F while in Afterburner. You can dial in the desired voltages.
