How hot is a really hot? Dual Athlon MP on Linux
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 _____________________________________________
Yes, I've seen systems range from about 34 up to 48... I believe AMD claims that they can run up to 70 (not that I would ever let mine go that high. I have an NFS server running a Tyan 2462 with Dual 1700MPs and they run right about 38-40. the box has been very stable and very fast. - Herman On Thu, 11 Apr 2002, Alex Daniloff wrote: ->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.

. If I were you (and didn't use a laptop) I'd set up water cooling. Then you could overclock too. tomshardware , amdzone , overclockers , etc. On Thursday, 11 April 2002 17:52, you wrote:

I've always wanted a liquid nitrogen cooled laptop, but I don't have the skills to make one yet ;) Regards, Keith -- LPIC-2, MSCE, N+ I can C for miles and miles Got spam? Get SPASTIC http://spastic.sourceforge.net

Well, what is a main reason for overclocking? Just to brag that you can run e.g. 400MHz CPU at 600MHz? How about performance and stability of the whole system? I don't think that such approach is a good for 24x7 production DB server, unless you just use it to run Quake in your leasure time. Water cooling solution adds an additional significant coast to the coast of the system, which is not always justifiable in our purchasing department. ------------------- pure the

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.
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.
We've got a bunch of (single) AMD boxes here , ranging from 1.4Ghz athlons (mine) upto 2000+ my mobo temp is around 41, my cpu temp is around 50 (and this is after extyra fans). Running big seismic inversions or large compile jobs will get the temperature of the cpu upto 52 - 55. When they get to 60 we have (you have) a problem. We have a few AMD boxes that are in use as number crunchers and they get to 55C on the CPU. When idling these are around 42 on the CPU/35 on the mobo Currently listening to: CD Audio Track 1 Gerhard, <@jasongeo.com> == The Acoustic Motorbiker == -- __O If your watch is wound, wound to run, it will =`\<, If your time is due, due to come, it will (=)/(=) Living this life, is like trying to learn latin in a chines firedrill
I recently upgraded my monitor from a DEC 17" to a NEC 17" multi-sync TFT. Both monitors were Energy Star compliant. However, after installing the NEC, the monitor was not powering off automatically. If I set suspend in my BIOS, the entire system goes into a suspend mode, which effectively shuts down my server. I have energy saving enable from the KDE control panel. The old DEC monitor did shut down after the set idle period. I've been playing around with the settings trying to find the right combination of settings to power down the monitor without powering down the CPU. (BTW: I've got HD standby disabled in the BIOS). -- Jerry Feldman Portfolio Partner Engineering 508-467-4315 http://www.testdrive.compaq.com/linux/ Compaq Computer Corp. 200 Forest Street MRO1-3/F1 Marlboro, Ma. 01752
