Try to kill off any programs youre not running so that they dont eat resources in the background. Make sure everything inside your computer is packed nice and tidy so that your fans can run more efficiently. Limit your computers performanceThis is taking a step more than the one above; limit how hard your computer (and the CPU fan) is working. You can try to lower the max number of frames per second the GPU on your computer processes. You can also try putting a cap on the max speed your fans are allowed to run but be warned; this runs the risk of overheating your computer.
