Why is my CPU cooler louder when using higher FPS?

I'm using Intel stock cooler and 60hz monitor. When I set in-game frame rate to 120fps, my CPU cooler is louder than normal. Should I change my CPU cooler?

Any reason you set it to 120hz as its a 60hz monitor? Smoother gameplay for FPS games.
Are you sure its not say the GPU fan/s as well? I'm not sure. GPU temp is around 70c.
How old is they system? What sort of temps are you seeing? 3 years old. Around 70c CPU and GPU temp.
Will it be not louder if I change to aftermarket cooler?

In theory, yes.

But in your case, it will make no visual difference as your monitor can display 60 FPS ( Frames Per Second ) maximum.

You would need a 120Hz monitor to display 120 FPS, so essentially you are telling the pc to process 120 frames worth of information, but then ignoring half of fit - Twice the workload for no benefit

I can't afford 120Hz monitor. My Intel stock cooler is not loud when using 60fps but is louder when using 120fps. An aftermarket cooler will not be not louder when using 120fps?

You are not seeing 120fps.

Your monitor cannot show anymore than 60fps.

You are needlessly running an extra load for no reason or purpose

But for me, 120fps is good for FPS games because of smoother gameplay.

I have delay mouse movement by using Logitech M100 when playing 60fps FPS games. After I change to 120fps, the mouse movement is smoother. Is it because of the mouse?

What games are we talking about here ? One in particular?

There are a few games due to bad programming that respond to higher fps as it overcomes issues within the coding.

Overwatch.

Most aftermarket coolers will improve the noise and cooling of your set up. Do you have a budget in mind? If you have enough space in your case you could look at something like:
https://www.overclockers.co.uk/alpenfoehn-sella-cpu-cooler-92mm-hs-043-al.html

Seems to have good performance for a reasonable price.
At the higher end you have big heatsinks like the Noctua D-15 and the BeQuiet Dark Rock Pro 3, but you're looking at spending £70+ there.. not worth it unless you're going to be overclocking.

How about Cryorig H7?

My only worry with Overwatch is it is both CPU and GPU intensive.

The noise might not be just the CPU....

I know its difficult but you might want to double check what is making the noise before you start spending money!

I hear the noise mostly from my CPU cooler. I put all my graphic settings to low in game and my GPU temp is 70c like that. Does GPU make loud noise during 70c?

Monitor the air temp going into your CPU cooler. I'm betting it get much hotter when you are running 120FPS than at 60FPS, because it's not the CPU doing the work but the GPU, and it's heat is heating up your case because you don't have case airflow setup properly.
I answered you on other forum.

So you mean there is no need to change CPU cooler? Do I need to install side fan to cool down graphic card so that the heat will not heat up CPU cooler?

Best way to find out is to monitor the airflow temp going into CPU and GPU coolers under load. Then we can see what the air temps are doing and try to adjust case airflow to keep the heated GPU exhaust air (assuming that is the cause) from mixing and heating the CPU cool airflow.

Usually removing unused PCIe back slot covers helps front ot back airflow and this usually helps keep the airflow to CPU cooler cool.

My casing is CM K280. Does my Asus GTX670 graphic card make loud noise when the temp is around 70c? Should I install side fan to cool down my graphic card or change CPU cooler?
