Right now I'm currently running stock H70 fans and not looking to upgrade the fans, just wondering if it's ok to use a fan controller? Also, any recommendations? I would need it to fit in the 3.5" bay as I have my H70 modded to intake from the front area where my 5.25" bays are.
Fan controllers work fine on the H70. I don't know why anyone would tell you not to use one.
However, a fan controller is not going to increase the speed of the fans. The H70 fans are rated at 1900 RPM and a fan controller will not increase that.
If you are using the cables with the resistors in them, remove them. The resistors will run the fans at about 1600 RPM, removing them will bring the fans up to 1900 RPM.
If you want higher RPM and static pressure you will have to change the fans.
There's a great list of fans in the OP (page 1). If you're only interested in more cooling and higher flow, you should try and get the highest static pressure you can get in a high flow fan. Just remember they're usually noisy at higher speeds.
Adding a fan controller so you can adjust the speeds is really a no brainer. Go tell that to the people who told you not to use a controller on the H70. Tell them that before giving advice they should know something about it.
