Changes on Acer Aspire 3003 WLMi

[RichiRich]

Hello and Happy New Year to all!

For almost 5 years I have this laptop, and that little processor serial a Mobile Sempron 3000 + 1800 MHz 128 MHz 800 KiB 9x 0.95-1.4 V 62 W

brackets, a couple of times this processor is capable of exceeding 100 ° because the heatsink fan could not let the warm air because it was Full of dust, so the performance drop was probably due to this ... Apart from this, I installed a new processor by making a risky choice and I bought on ebay an Athlon 64 3200 + at 2.2GHz desktop processor, exploiting the fact that laptop uses socket 754

Athlon 64 3200 + 2200 MHz 512 KiB 800 MHz 11x 1:40 V 59 W Socket 754

Even now, despite the new thermal paste and the copper plate of the heatsink was not completely clear why I had removed the old thermal paste and black plastic for protection, not only the temperatures were lower but the heatsink fan is not running ... already there and I worried, then I quickly turned off the laptop and I turned on again, once I arrived in windows checked immediately with the software RightMark CPU clock utility and incredible thing was under 30 degrees with which the old heatsink could only dream ... why the Sempron now traveling on 50/60 at rest to 70/80 under certain circumstances it is very often with the fan at the highest
Now with the new processor after a month of use I can confirm that he has chosen well, in fact a fan off the processor will not move from 45/50 degrees, and the first step of the fan is activated to 59/60 degrees and immediately reported the temperature at 50!

heatsink off a laptop and download with emule!

With all this I am very happy! After this change, I would make a further, which is to increase the ram from 512mb (256 * 2) DDR shared with 32 to 2gb (1GB * 2), only that I have tried everywhere on the internet and I found no confirmation that a sort of ram can be mounted, and even those of acer service center have been able to respond to recall the service center of Milan for the changes to "guarantee" ... Guarantee? the warranty has expired for the past 3 years, and I already changed only by the DVD recorder!

than I would ever make another change on the processor, but in this case the same heat sink, the change is in step 2:

1) Open a hole 4 * 4 cm with protection and dust filter for direct intake of

2) mount a regulator to do in order to bypass the automatic adjustment of the fan to keep it with a minimum of movement to leave the air .

Point 2 has already done some problems, which saw the fan is from bios how do I send it to the maximum and then check with the potentiometer?

1) Say that there is no problem, I am in a situation like I did a series of holes in the plastic with a tip of 5 mm. Forming 3 concentric circles, and cooling has improved a lot.

2) This is a more difficult for the following reasons:

- The place where the potentiometer, which we're not in the case of the laptop?

- To connect, you disconnect the fan from the connector, finding a spot where you can withdraw 5 v. needed to nourish it and then connect in series by entering the potentiometer.
You can not take power from where it takes now, because as you said yourself there is fed by the bios.

Meanwhile, thanks suffered cmq already when I opened the laptop to change the recorder had noted that near the sides, especially just behind the heatsink near the attack VGA there is a large empty space left for maybe another door, then space ... plenty to feed a 5v, surely I can take it from a usb port, but I can always use the same attack to get the power?
