i've managed to hit 36 degrees too, in a/c room. i think 36 degrees is the lowest already for the proc.

even my intel c2d laptop can't reach that low temp when the fan is even noisier than the K50AB fan.

i guess the K40AB/K50Ab design for cooling is just awesome.

correct, I'm using Vista, and if I turn on my laptop with >96% charge with adapter plugged in, the laptop battery won't be charged whilst the laptop will directly draw power from the adapter.
I'm not sure if XP has this function or not... perhaps not.

hmm so with this so-called 20% cooler thing, what is ur lowest temp?

With my K50AB, i can hit 36 deg celcius when idling inside air-con room, and another forumer also managed to hit 36 deg celcius when idling in non-a/c room.

i never encountered this problem before. maybe u got a lemon unit?

I can choose when to use Auto-Fan control and when to use Max-Fan speed. Max fan speed really rocks as even the top part of the laptop doesn't feel hot anymore.

you can refer back my earlier post in this thread. i'm actually exploiting a bug in the system. really love to run at 36 deg celcius. furthermore, the fan at full speed is not that loud compared to some laptops on full fan speed.

Ok. Here's how I do it for those who didn't really get what I said earlier. FYI, I'm using K50AB purchased from All-IT.

Step 1: Update Windows Vista completely (I'm using Vista Ultimate 32 bit).

Step 2: Install AMD/ATi drivers from official website (not Asus website). Other drivers, use the included driver CD to install all.

Step 3: Switch from HD4570 to HD3200 via ATi driver inside Windows.

Step 4: Go to Sleep mode via Start Menu.

Step 5: Wake up from Sleep by pressing any key or mouse click.

Step 6: The fan will now be spinning at full speed!
(Note: You can change to HD4570 back now for gaming, and the fan will still be running at full speed. However, if you plugged/unplugged your power supply, you need to restart Step 3 and onwards)

Key benefits:
- Temperature at idle is as low 36 degrees Celsius. You will realize even the hard disk and top-right-hand side corner is no longer warm!
- Temperature at gaming is still very low, since the Asus K50AB is designed to cool all parts of the laptop (comprehensive-exhaust system).
- The air that the fan is blowing out will not be as hot as before as the fan speed can push much more air out, thus preventing heat build-up.
- Longer life for your laptop components and battery.

Not really exploit la. But saying exploit sounds cool. lol.

I used with back cover on, but I used in air-con room. Maybe one of these days will try with back cover open inside air-con room and see if can go lower than 36 degrees Celcius or not.

K40AB and K50AB both brothers mah. They are the same in my eyes.

Your welcome.
Do test it out and let us know here how it helps especially if you are using K40AB or something.
K40AB should technically benefit more since the insides are more cramped up - shorter distance for heat transfer via airflow.

I used the driver from the link posted by sifu Najmods in the first post.

i can manage to run my K50AB at temperature of 36c idle. is that called heat problem?

I'm just happy that for RM 2k, I can get a lappy which has a numeric keypad and large screen!

For me, more space is always more important than speed, which doesn't make that much difference.

Wow. The K50AB club is getting bigger and bigger. I guess more people prefer bigger screens these days eh.
