I had installed FC3 32bit on my ASUS Z8100 AMD 64, and found that the fans were so load that people were asking about how many gears I have in my laptop. I finally made the move up to FC3 x86_64. After a full update from distro. I had successfully updated after booting into init 3. My laptop runs much better and quiet. The fans are not working as hard. I hardly hear them.

To: fedora-list@xxxxxxxxxx Message-ID: <230b19f2050319033336a69629@xxxxxxxxxxxxxx> Content-Type: text/plain; charset=ISO-8859-1 Hi, I have an AMD Athlon64 3200+ machine with Fedora Core 3 (x86_64). How can I exploit the qool'n quiet feature of the processor? It doesn't seem to decrease the speed. cpuspeed runs and the processor is recognized as I see in /var/log/messages. (Although there are some warning messages as well: "powernow-k8: vid trans failed, vid 0x3, curr 0x4"). Motherboard: MSI K8N Neo2 Platinum Zoltan
