Controlling the CPU heat generation - Intel Core 2 Duo on a laptop
Hi everyone,
I have got myself a brand new laptop with the Intel Core 2 Duo 2.0 GHz CPU, which is great. It has one problem though; it becomes very hot when there's a lot of CPU usage (and when it has first gotten hot, there's no way back, it seems). This only happens when the AC power plug is plugged in, and I suspect this is because the CPU is designed not to go to its maximum level when only relying on battery power (which is good). What I would like to do is to have some degree of control over how hot the CPU will get, so that the CPU fan won't make so much noise, and so that my wrists won't get burnt lying on the notebook while typing text (as they are right now). I guess the solution would be something like setting a maximum frequency/voltage or similar - to mimic the way it behaves when it's just on battery power. It's not a feasible solution for me to just take the AC plug out, because I'm usually using the computer for hours at a time. Can anyone tell me if this is in any way possible? What software or drivers would I need? Best regards, Christian |

No that depends on your power profile settings, a feature in your bios or software running in windows. What I would like to do is to have some degree of control over how hot the CPU will get, so that the CPU fan won't make so much noise, and so that my wrists won't get burnt lying on the notebook while typing text (as they are right now). Impossible, you want two opposing things - for it to simultaneously make less noise than the inherant design causes, and also be cooler than if the fan weren't running at same high RPM. Well, there IS one obvious alternative, use the included power profile software to choose a lower performance, lower CPU speed. I guess the solution would be something like setting a maximum frequency/voltage or similar - to mimic the way it behaves when it's just on battery power. Use the included softare, it isolates the user from these choices and uses all possible, available power saving options. If you can't find this utility, look again on the notebook and if no luck, look on notebook manufacturer's website as it is a standard notebook *feature* to have this. It's not a feasible solution for me to just take the AC plug out, because I'm usually using the computer for hours at a time. Can anyone tell me if this is in any way possible? What software or drivers would I need? You didn't mention your actual hardware beyond a family of CPU, which is a bit insane in a hardware newsgroup. We deal in specifics, every last detail. |

Thank you very much for your answers - I think this is exactly the advice I needed. I'll try to remember to give a more specific hardware list next time. Best regards, Christian |
