I've got a 1ghz AMD chip that I had at 1400mhz for awhile. With the Delta 7K RPM fan. The noise was a pain so I took it back down to 1000mhz and put the Taisol fan back on. Now, my temps are about 50C with nothing going on in the background. Is this high for this CPU or about normal? It's been a few days so it should have cooled down by now.
