I've just edited a profile and changed the fan speed with the fan mod. I've decided to go with 35% for idle/desktop and also underclocked it to 500/810 (3240) with ATI Overdrive. Is it a good idea to underclock it if it's going to be doing very little or should I leave it to do it automatically? Other than video playback I can't see anything that will demand much of it while say browsing the net or using Photoshop. At these settings the temp is ~59c which isn't to bad considering it's in a HTPC case. Also, what would be a good speed for when I am gaming? I've decided to go with 40% but I don't know if that'd be enough. I haven't overclocked it either.
