Hello SuSE folkz, Recently I've assembled Web, DB and file Linux server on Tyan Tiger SMP2460 MB with two AMD Athlon 1500 MP CPUs. The BIOS has a nice feature to measure CPU core temperatures in C. Initially I used Thermaltake 6cu+ aluminum heatsinks with the copper inserts. I used Dough Corning white silicone heat sink paste. Idling CPU temperatures measured through the BIOS were at 35 and 36 C on CPU0 and CPU1. It's good but heat sink fans sounded like a jet on take off. I changed these heatsinks on Millennium Glaciator I (not II) pure copper heatsinks with built in fans. They came with Cooling Flow heatsink compound. The server became very quiet but the idling CPU temperatures raised to 40 C on the both CPUs. I can't take measurements directly from from CPUs only through the BIOS and onboard sensors. Could somebody tell me please if this temperature at 40 C is normal on idling AMD Athlon 1500 MP CPUs, or it's a little bit to much? Shold I change heat sink paste, fans or just live it like it is? Thank you in advance for any thoughts or suggestions. Alex _____________________________________________
