vLeader is built using industry standard technologies. Your computer is built to detect an increase in heat on the CPU/GPU and spin the fans at a rate necessary to cool the GPU/CPU. If you have only a small amount of RAM (4GB) then your computer will swap applications stored in memory to disk which will increase the pressure on your computer.
If you are concerned your computer is getting too hot here are some things you can do:
1. Place your computer on a flat, hard surface so the fan can expel the hot air. Your lap, bedding or a laptop case can all prevent air from getting away from your computer
2. Restart your computer
3. Close camera-based applications (Zoom, FaceTime etc)
4. Use Task Manager (Windows) or Activity Monitor (Mac) to determine if there are other applications using a lot of CPU
5. Work in a cool environment. If it's 90 degrees outside, that will contribute to your computer running hot
If your fan makes a lot of noise it is not due to software but due to the bearings in your fan, or due to dust and dirt in an around your fan. Ask someone qualified to maintain your computer to inspect your fans.
