The fans are always loud even on idle

Hi everyone, i need help with my laptop Specifications: MSI GL63 9SFK Intel Core i7 9750h Nvidia RTX 2070 16 GB RAM about a week ago i had no issue playing on this laptop and then suddenly the games started lagging and i get 20 to 30 fps in every game, i tried uninstall and reinstall the Nvidia drivers and still the same, i also tested the games in lowest quality but my games are still laggy and i still get very little FPS, can somebody help me with that? Thanks,
