A2D cooling fan non-stop running

Hi!

Just two things noticed while finding out the solution to the problem.

1. Sometimes, for no good reason at all, CPU temperature just drops from whatever it currently is (for example 53C) to a very low value (7C). The moment after that it jumps back to its original value. I noticed that with MobileMeter on a short update interval. I also noticed that this is the time when a "never stopping fan problem" usually occures (at least by mine A2D AMD2800+ notebook). Asus Probe doesn't seem to show this phenomenon (maybe some extra " future" by Asus Probe, hiding errors?)

Here are two snaps taken, showing MobileMeter main window. You can clearly see the temperature jumping. First snap was taken exactly on the temp jump.




2. I also found out how to "boost" the heat to a processor. At full power (2133Mhz,1.65V), the CPU heat circles around 55-65C and is constant. The fan is on. If I than lift my notebook and turn it 90 degrees left (so that I am looking at the turned ("pivot-ed") LCD while the notebook keyboard is at the right facing vertically up), the heat of the CPU rapidly increases. I let it increase up to 90C, when I got scared and put the notebook back on the desk. While increasing, you can hear the fan kicking to higher speeds.

So if the non-stop fan problem occures, I could just turn my notebook until it reaches 70C and the fan starts turning faster, than lay it back down, and the fan would go back to 3000rpm and eventually to 0rpm.


I hope I made at least a couple of you wonder, why my A2D behaves like that. If you can try that yourself (it isn't THAT hard ), you could report, if your machine behaves in a similar way.

If anyone of you A2D users still care about the fan problem, I (sort of) found out the best solution, how to regenerate the non-stop runninh fan problem:

1. Download CrystalCPUID (google for it)
2. Install and run and go to Function -> AMD K6/K7/K8 Multiplier
3. Click 'Enable Change Voltage'
4. Make sure that the Voltage is at 1.650V
5. Change the Multiplier to 14.0x (CPU is on 1866.67 Mhz)
6. Change the Voltage to 1.550V
7. Close the CrystalCPUID and wait. The fan problem should arrive much sooner than usual.

The problem is somehow related with repeatable turning off and on the fan. BIOS sc**ws up at some random moment. [email protected] is for my A2D the most optimal configuration, in which the fan is turning on and off all the time and thus sooner or later never stops util the next restart.

This however works on my A2D. If it doesn't on yours, first make sure that the activated Power Scheme of XP is Always On/Maximum Performance before doing the steps above. If something else (either XP or some third party program) is changing the frequency of the CPU, the CrystalCPUID will not work.

My A2D starts turning the fans non-stop in about 10-15 minutes after I do the steps above. Your mileage may vary depending on room temperature and the amount of dust your A2D is stuffed with.

Hi, i did everything as discribed in your instructions, just, at the end, the circle would stay red all the time and prime wouldn't go further than test 1 (without any error message)
is this normal or what did i do wrong?

 

oops, the thread above was adressed to mhko00
sorry
