Problems? See this thread at archive.org.
i bought it yesterday and used it but the temp in idle is 50'c and if i use AC adapter [for highest performance] it's temp is 60'c
my room temp is 27'c and i use asus probe to detect my notebook temp
my cpu is amd athlon xp-m 2800+
anybody who use a2d please tell me is this abnormal temp?
p.s. sorry for my english grammar

This temp does not seem to bad. Just remember that this is essentially a desktop CPU with a few minor adjustments. My old desktop AMDXP 1.6, used to run at this same temp, with a 92cm fan + massive heatsink on it 24/7. So when your running a XP 2800+ at full speed off AC power, your going to be generating a lota heat, I would be more worried if the fan wasn't kicking in that often to be honest.

Hello,
Ok, I have bought my a2d (amd2800 ati 9600) second hand as a reall bargain and had that **** fan issues (overheat/jam/low cpu temp, hot case temp) Though I dislike AMD (Nothing about the performance, I simply dont like the name of it, intel inside sounds cool) I love the performance of this babe (especially the 9600) and didnt want to change it.
I am from a country where all guarantees are solely on papers and does not apply in real life, service personel is always chosen from the ones paid the lowest fee and as a result having the tiniest brains blah blah blah... not excluding asus.
So I went out for a solution by myself. Read all threads in this site and many other sites including asus technicians posts without finding a solution.
Now what I have acieved so far...
1. I have totally dismantled the notebook to the tiniest bit, hacked ino the fan. I dismantled it too , it was a ac center rotor surrounding stator engine so It was easy to set it apart.
2. I cleaned it with various gentle chemicals (no alcohol glass cleaners first, then mild soap (ph7), rinsed few times with water then used several times degreaser contact cleaner (not the oily one) . I looked up for a good degreaser but as the prices were sky high, so went on with a cheap chinese one which worked like a miracle (Before I bought this one I was using Philips now I will never buy Philips they sell canned water instead of greaser when compared to this chinese crap)
3. Finally I rinsed every bit of the fan with pure water then
washed with pure water and immediately dried it with a hairdryer. I applied this procedure from step 1 to 3 to all of the fan casing.
4. I used some silicone grease on the stator and assembled the fan. (This grease is mostly used for harsh conditions theoretically it never dries or bonds , I knew it from my scuba gear we depend our lifes on that lubricant but thats another story)
5. now the coppersinks : There are two copper heatsinks. One with L heatpipe for cpu and one under the top cover for the graphics card attached to the cover of it) When I opened them they were nearly clogged with dust. I took them directly to the bath washed then applied the same procedure in 1-3.
7. The original thermal paste crap (was gray color on mine) was dried out on both sinks and was hard as a mules tooth. I worked about half an hour to clean it out without scratching the contact point. For the first 25 minutes I used every chemical I had (mild acis, detergents alcohol, acetone etc etc) but could not remove it totally. Then I used that infamous chinese degreaser on that one and worked out like a miracle again. When finished both heatsinks looked like brand new and fresh out of the factory.
8. This time I didnt went on cheap and bought the white thermaltake heat paste crap in a case which looks and probably was produced hipodemic injector needle (Those eastern people have a great imagiation for using one thing for another purpose) I applied it by a plastic card to make a smooth surface. voila ! it's finished.
9. I reassambled the notebook. (How did I do that ?? of course with reverse of the method I used to disassemble it )
Now the results :
1. Fan is much much silent than the original, both in decibel and the turning on intervals are much less. Working wih it for a month without a problem.
2. cooling problem is solved much cooler it is ! Noise problem is partially solved, it is much more silent and turns on much less (dont have a tool to mesaure decibel but roughly half the noise) but still not as good as I would liked.
3. About jamming problem : I tried half diassambled run tests to find out if the heat receptor(thermocoupler) has the problem , or it is a general heating problem, or a software one. Voila ! the cpu heat and heatsink is approximately as the monitor programs say, and as the posts in this forum. But.. the pretty ati 9600 gets extremely hot. With using speedstep and running on 400 mhz I have found out that %95 the stacking of the fan is not a real stuck but caused by the over heating of the graphics card main processor.
4 . why the graphics card gets hot? 2 reasons,
a) the heat pipe which carries the heat to the heatsink is wrongly designed in the factory. It is round at the edges, half of it sits on the graphic card's main processor following with a gap (about 2 mm) which sits right on the graphics processor. The thermal paste helps a bit but still it is a bad thermal contact in this way.
b) the graphics card heatsink is too small for cooling . I didnt calculate or mesaure anything but it gets hell of a heat when even notebook is running idle.
5. What can be done from now on : The heatsink of the graphics card must be enlarged for a total solution. 3 step idea for this :
a) A direct heat pipe between cpu and graphics card heatsinks which can be dissasambled easily must be constructed so that excess heat will pass onto cool and much larger cpu heatsink which eventually equalise both of their heats, eventually lessen the fan turn on times and probably put an end to the fake fan stuck problem.
b) Luckily there is a great hollow in this notebook hust behind the cpu heatsinks head which sits on cpu. Probably it was for the pentium version of the notebook as the cases are the same. You can not miss it. directly under the laptop wih a square grid. It is a 2,5 cm heigt clynderic hollow with a radius more than the diagonal of the square metal grid. With a radial copper heatsink which can fit there and a heatpipe the heat consumption for the present heatsinks can drastically be increased. Even a 5v low rpm low noise cental fan (like the ones used on graphics cards) can be attached there which will take power directly from an usb port internally. With such a modification the main fan most probably will be fully functional and will also never need to work again except emergency issues (overclok etc)
c) for the main fan I did the best treatment and still it is a bit noisy. For a solution it can be changed with a same diameter same voltage low noise same rpm (sky high pricy) fan. For improving the aerodynamics of the casing som modifications can be made (inside of te fan casing is quite rough and this pretty much can cause the fan noise)
Finally, Jamming problem is still there but much much less it happens. and now I know why it happens and have an idea which I will apply and inform you if I succeed
Warnings !
1. This worked for me, might not wor for you .. no guarantees !
2. Bewarned thee !! If u dont know how to open a notebook dont do this at home ! Besides cooking your notebook, you can seriously hurt yourself with the chemicals or tools.
note : sorry for the sloppy english, It is not a native language for me, I learned from holywood movies
Thats it, have a nice and a silent day !

my asus a2d is very hot
