Noisy gaming computer Fans

Gets noisy when gaming, when I'm researching you still can hear the fans/gpu at Max Speed none stop
At the moment i think all the fans are running at full speed that's why its noisy ?
OR the case is too compact not enough room ?

The case seems not too bad, but you have a lot of fans within.

Depending on the fans brand, the speed, etc... a 120 or 140mm could make a lot more noise than others, for example a 120 fan could run from 700 rpm to 2500+ and that alone could have a diference of 15+ dBs

You must put the brand and speed of each one to could properly advice you.
