Most here will probably say an emphatic YES. Me, I just use SpeedFan. I had a Hardcano (TT) and while it was nice and looked cool, I just prefer software fan control. Maybe I'm lazy lol, but SF does everything for you so no knobs, no forgetting to turn them up, etc.... Also, w/ a controller, and this might not pertain to you, some have temp probes (usually 4) and all fans must be connected to the rear of the controller. It can really make for a messy case, or if you decide to hide all the wires, can make for a very tedious wire management job. Just my experience. Are you looking to quiet your pc?
