PS3 Fantable in SW Syscons not working?

Hey guys,

i was messing around with fantables in my slim consoles and came to the conclusion that my fantables do not change anything to the fan behaviour.
On the first console i wrote paco's fantable to 2c0 and the fan behaviour is still the same as stock. When i do r 2c0 1a it perfectly shows what i have written to it, but the syscon doesnt follow my table. However, after messing around with console 1 its not possible to connect via uart to syscon. I exited via exit command and since then im not able to auth, it always refuses with "auth1 response invalid". Whatever, now i took the second slim (same model, 2004b, dynamo01) and wrote my own fantable to it. And same thing, it doesnt follow that table.. fan works alway with stock speeds..
where is my mistake, what am i missing here?

i wrote the following tables to it:

RSX
w 2c0 40 31 00 00 00 48 31 80 2f 00 4d 37 00 31 00 5a 37 00 34 00 80 3f 80 3d 80

Cell
w 250 40 37 00 2f 00 48 39 00 31 80 4d 3d 80 37 00 5a 3f 80 3d 80 80 43 80 3f 00

These should make a noticeable difference as they are pretty aggressive curves, but at 73degrees Celsius on both chips the fan is running at 29% what looks stock to me.
Both consoles ignore what is written to syscon.
r 7fe 2 is FE 7B
eepcsum is 7BFE so everythings fine.

Does anyone know whats the problem?
 
Okay, just in case you wanna know, i figured out there were some bugs in my fantable. syscon does now sync the fanspeeds with my fantable. seems like its not a good idea to do both rsx and cell fantables, if you dont know 100% what youre doing. i would recommend only adjusting the RSX curves at sherwoods due to syscon seems to completely ignore your fantable if it doesnt fit a 100% its logic.
anyways, i got this working now.

as i mentioned before, slim #1 doesnt let me access the syscon anymore. ive checked my wiring and everything is fine.
it perfeclty worked until i quit via exit command, since then im not able to auth anymore. UART connects with every other console, only that particular slim always refuses with "auth1 response invalid".
maybe someone can help me out with that problem? aint got no further idea, but maybe someone else has..
 
Yes, in fact, you only need to adjust RSX, Phat or Slim is applicable, because the temperature rise of RSX is faster, and it seems that only a part of the address is edited when only one address is used, for example, the address 2c0 seems to cover only P0 to P3? I forgot, is this the case for you? If you are fiddling with the syscon of Slim, can you help me find the value of address 7f2? I have a Slim 25xx, and I messed up when I changed the sum, w 7fe I wrote w 7f2, and I didn't save the syscon, so I don't know what the original one was, thank you!

Sorry, got some stuff to do so havent been online for a few days. I will throw a look at this address in a few days and let you know.
