Simple and true, for everyone
if you want the guide for the 5830tg I'll send it to you by email, email@example.com.
I I find the original acer manual on somme site a while ago... I alredy tear down mine twice, the first time for repasting the processor and the gpu, the second one to take off the plastic net that is placed undrneeth where the ventilation holes are (it lowered the cpu/gpu temp by almost 10 °c) it will take more dust but i clean the fan every 3-4 monts annyway... The other modI've donne is make just a litle bigger the holes underneeth the fan (just a litle bit with a nail file? I dont remember the word).
for annyone interesed to upgrde the cpu from i5 to an i7 I tryed two that work on mine now the first one I'll find at a good price on ebay I'll buyit... the two thatwork are: 2620m and 2630m,maybe will work the i7 2640m but i have not tryed yet (the two Ive tryed where from a client computer that ihave for cleaaning).
for the fan controll still tryng to figurethe exact bytes (offsets) of the embedded controller with ac fan controll, untill now I figure the 180 is the gpu temp, 179 one of the cores temp and somme people say that 174-5 arethe ones for the fan but i don't know for sure...
Maybe next week I'll add a switch for manualy turn the fan from his controller to a 5v rail since the fan can spin much more than itdoes when controlled by bios (by the way i also have the bios unlock update), if annyone want to put those tweeks on internet I'll sen them to you and you can share them...
I just love my 5830tg and I think that by sharing all wee have wee can make it so much better, by the way I've upgraded the ram from 4 to 8gb (tryed even 2x8 gb and work) and the hdd to an adata ssd (in mine is faster than a samsung or a crucial) and it works so much faster... by the way take care when you open the computerat the hdd connector take it of the mainboard side not the hdd side since the sata connector fail on mine (the solder whires are so thin, it took me 3 ours to resolder one whire )
Ok I'm back :)
So HARDWARE MODE ENGAGED :
since there is no way (yet) of manualy controll the fan with software and I was not pleased with my temperatures (even after repasting, taking out the nets, bios crack ecc) this time I go the old school way hardware way. Theory: the fan has 4 wires: red (positive 5v), Black (negative), Yellow (rpm signal) and Brown (PWM signall), red and black are always on so when the EC (embeded controller) send a signal from 0.05 to 5V (to brown wire) the fan spin acordinagly, thru the yellow the motherboard read the rpm therfore i've desoldered the brown from the fan and rewired thru a litle switch(like the ones in the litlle toys) with 3 pins: the original brown that is tied to the motherboard is on one end pin, the fan whire where the brown where goes in the middle and the other pin goes in paralel with the red wire on the fan. When the switch is on one position,the fan recive the original signal from the computer, when the switch is on the other position, the fan recive full 5v so it spins at max rpm.
There you go :) not so elegant as a softwre controll but hey desperate times require desperate measures :)
