Go into Web-man enable Dynamic Fan control, also commands as in select + dpad up equals max temp and vice versa as well dpad left + select will allow u to control min/max fan speed in % format. Go into whatever version, if u are using Irish-manager enable web-man payload for fan/temp control it's not web-man it's your setup. For point of reference so you know Irish-manager comes in many forms, ITA Manager now Game-sonic manager. But I'll guarantee that's Ur issue. If Ur on ITA 4.50 you need to go into ITA Manager for your fan speeds to be set. That's web-man's best feature in my personal opinion. However remember if a game freezes and you need to rebuild the file system make sure web-man is enabled before you do anything else, sometimes it will not be enabled after System Rebuild or File System Rebuild.
