Have two computers running Soyo Dragon+ motherboards with AMD xp 2000+ (1.67 GHz) and xp 2600+ (2.08 GHz) with cpu temperatures of 40 degC and 54 degC, respectively, as shown on the Soyo Hardware Monitor. Recently the xp 2600 has been shutting down abruptly and I have to restart. Yesterday I couldn't even restart without it freezing up or shutting down once into winxp-pro. Today it started up and I deleted Norton AV in WinXP just in case that was the problem. It is currently running so I beginning to think that the cpu temperature gets too high. Does anyone know if 54 degC is marginal with running added software causing it to go over the limit? What are the temperature limits of cpu's?
