I've been thinking... I have an Athlon 2400+ in my LMP Case PC, I have a huge thermalright Heatsink and the ZM80A Heatpipe cooler on my Radeon 9500. Would underclocking my HTPC make the CPU run cooler? Cool enough to not need a fan on the thermalright? I play no games and very rarely use D-scaler. Almost all use is ThaterTek, Nebula TV card or MediaPlayer so I don't think I'm taxing my CPU's performance potential right now. I'm running at a constant 50c even when not in use, up to around 56/57c in D-Scaler. Any thoughts? Mark.
