    I’ve recently bought an ASUS A6Rp (Celeron M 440, 1.86 GHz) and installed Notebook Hardware Control. CPU temp reported seems too high, 44° C at boot and 55° C after few minutes while ambient is 32° C (My desktop, Celeron 2 GHz, starts right at 32 ° C and reaches a steady 38 ° C). Then I installed Core Temp. CPU temp it reports is nearly 5° C lower than NHC, all the time. So I went on to install RightMark CPU Clock utility and it concurred with Core Temp. This is still much higher than ambient at boot.
    I’ve heard a lot of good about NHC. What’s wrong? And what’s with CPU temp so much higher than ambient at boot?

    Those are actually some pretty good temperatures. You don't have anything to worry about. If the temps get up to 70C I would start to get concerned but your temperatures are completely normal.

    Most likely it's because all the power-saving features are only enabled after boot. At boot, everything runs at full speed (That's true for CPU, GPU and pretty much all other hardware). Once the system is up and running, the OS can tell everyone to go into power-saving mode. And until that happens, the CPU will probably run hotter.

    There are two different CPU temperatures from different sensors : The core temperatures and the ACPI temperatures. Often they will be up to 5C different. The Intel Thermal Analysis Tool will read both.

    Notebook CPUs temd to run a bit hotter than desktop CPUs under low load because there isn't a big fan blowing lots of air continuously. However, provided the fan cuts in when the CPU gets to around 55C then there should be no worries.

    One more thing, I’ve just installed Speedfan and there’s no report of fan speed, the field is just blank. What’s with it?

    A few questions regarding the Thermal Analysis Tool.

    First, Merom. It states Merom as Pentium-M, but does give you a slot for both CPUs (ie. 0 and 1). The help file states the tool requires a Pentium-M processor. Think it's valid with other ones too?

    Second, Merom. A few minutes after pushing 100% workload on both cores with the Thermal Analysis Tool, I breached 90 degres. Stopped it there. Does anyone have experiences on how much the Merom can actually take before clogging/shutting down/damaging itself? Assuming the TAT results are valid (which they seem to be, looking at NHC).

    Not all machines are supported by Speedfan. So if it's blank, then SF won't work with ur laptop.
