temperature of Dothan 1.6

[drnoom]

Hi,

I would like to know about the temperature of Dothan 1.6 GHz.

Is that ok for my T40 with Dothan 1.6?

100% full load = 63-65 oC Max.

when idle @ 1.6GHz ~ 53 oC
when idle @ 600MHz ~ 47 oC

Many Thanks.

Your CPU-temperatures sounds fair (= reasonable and healthy) to me, assuming an approx. 20 C ambient.

If you use the "Search" function in this forum, and search for "Dothan 1.6 temperature" (and select "Search for all terms"), you will find a number of threads reporting what you ask about. Also, many CPU and GPU temperatures are reported in the thread Managing Pentium-M Speed/Voltage with software - read on...

You can (significantly!) reduce heat (and by that power dissipation, hence increasing battery life) by installing Notebook Hardware Control and use that to undervolt the CPU and downclock the GPU. If you check the post of Mon Jul 30 in that thread, you will find link to an ACPI file for a T43p. I guess it will also work for a T40, but I honestly don't know (I'm using it on a T42p).

By the way, check if your T40 has or allows for a long fan - see the Hardware Maintenance Manual - ThinkPad T40, T40p, T41, T41p, T42, T42p - this will better cool the CPU and especially the GPU compared to the short fan, used in many T4x's. The long fan may further reduce your temperature.

a million thanks, Johan
