I use this PC to mainly play CS GO and PUBG, but i also work on it, coding in HTML, CSS, PHP, and i also photoshop and stuff.
I have 3 x Phanteks PH-F140SP on the front, controlled by the motherboard on the standart setting. Both fans on the CPU cooler are also on the standart setting.
I have no fan on the back, and i kept the top closed. I can't even ear the PC working.
