    Hi,

    When in AC mode my Asus F3Ja has the fan always running. I tried all the Power4Gear modes. Mine has a X1600 and a T7200 processor and it looks like in AC mode the cpu doesn't adjust the MHz automaticaly to the cpu load.

    Do you also have this kind of behaviour? What mode in Power4Gear do you use?

    Any ideas to make the fan run slower / don't run? in battery mode it doesn't run for long periods of time.

    I believe this laptop needs a damm BIOS upgrade to make the fan run slower while on AC mode. If I can't fix this I will have to return it :(

    On your desktop, right click -> properties, screen saver -> power, then in the Power Schemes set it to Power4Gear. (Of course do this while plugged into the outlet)

    Next press the P4G button and change it to high performance, this should speed step your CPU.

    Also you may want to use NHC or RMClock or other programs to undervolt the CPU at higher settings.

    Just and FYI NHC also has an ability to speed step the CPU aswell, called dynamic switching.

    using NHC right now in dynamic stuff... The temp is at 40º but the damm fan is still running... The cpu is at 1Ghz...

    In battery mode the fan doesn't work much but while in AC it works much more, eventhough the cpu is at the same speed and the ATI powerplay setting also being the same... It's just a weird thing, the fan doesn't need to run, it's only 40º !

    It sure does look like it doesn't care about temps or reacts to them very very slowly...

    looks like the fan only gets off when the cpu is at 35º... or maybe it doesn't care, I don't know. It looks like it runs when it's at 40º and stops when it gets to 35º. Any way to change that? (40º is not that hot and prefer it to be hot than noisy).

    Usually what happens, is that when temperatures rise, the fan would kick into higher rpms to cool it sufficiently, or try to cool it to drop the temperature after your done doing intensive work.

    However your stating at low temperature 40 degrees your still getting fan noise? Is is as loud as if the temperature is at like 50 or degrees?

    This may also be the case of a faulty fan, thus causing excessive noise.

    Have a look, try undervolting, record temps doing different tasks, and on a scale of 1-5 describe the fan noise level in your opinion for each situation.

    At 40ºC the fan is loud and I never heard it any louder so yes it's as loud as 50º. It just is at maximum speed at 40ºC which is weird.

    Does someone knows if this is my only problem or all Asus F3Ja (or similar) are like that?

    The usual situation on my F3Jc is that the fan is off until 38c, at low (but audible) speed stays at 39-43c, revs up progressively at 50c and 60c. Max I've seen is 61c under heavy load. That shouldn't matter so much that my CPU is lower-end, should it ?

    I havent been monitored temperatures and such, but it seems my fan only kicks in when I load my cpu alot (which causes more heat). When I exit a game and P4G is running Super Performance (AC) the fan slows down when I change to quiet office mode. Doesnt seem to care about the temperature the game just caused.

    Fast CPU => generates more heat. Smaller, thinner laptops => less space to disipate that heat passively, active cooling is required. That's the trend.

    Many Core Duo fans kick in at 35-36 degrees. If the engineers at ASUS think that fan cooling is needed at 36 degrees, then fan cooling is needed at 36 degrees. If I were you I wouldn't mess with that.

    Basically, the situation is normal and many notebooks nowadays will have fans "always on". Just that probably some are more noisy, and some less, and even more importantly, some people are more sensitive to fan noise, and others, less.

    (none of the above are really new or my idea, the same discussion was going on on the forum almost a year ago)

    I don't find the fan noise of my F3Ja to be annoying. Because it runs cooler, it's much more comfortable to use on lap. My previous Asus was silent but it did get quite hot.
