Hello, im trying to make my fan quieter i have cleaned it out and also put some 3 in 1 oil on it, but doesnt seem to go quiet... the tower seems cooler but fan still noisey.

If it's sounds way too loud or sounds wrong, you may need to replace it. If you get a larger fan, as long as it fits, you can have the same cooling at a slower RPM, and have it be not as loud.
