I'm putting together my first PC and will be using integrated graphics until I can afford a dedicated GPU. The Lian Li Lancool 207 includes two front intake fans and two bottom intake fans, and I plan to use one rear exhaust fan. Since there won't be a graphics card creating extra heat, should I run the bottom fans normally, reduce their speed, or turn them off? For now, the system will mainly be used for schoolwork, browsing, YouTube, Overwatch, and Fortnite on integrated graphics.

Without a dedicated GPU, the bottom fans aren’t especially necessary. The front intakes and rear exhaust should be enough for general use, so you can leave the bottom fans off or set them to a low speed. Once you install a GPU, you can turn them up if temperatures call for it.
The best settings depend on the CPU and its temperatures, so there isn’t one universal RPM recommendation. Also, integrated graphics performance in Fortnite and Overwatch will vary a lot depending on the processor, memory configuration, and graphics settings.
Set up a fan curve rather than choosing one fixed speed. Keep the fans slow during light workloads and have them ramp up as temperatures rise. That keeps the PC quieter while still providing cooling when needed. Check your CPU temperatures and adjust the curve if they get higher than you’re comfortable with.
