Kheh. I buy used EB 2570p and I am crazy happy.
Display not so bad, like I feared. Socketed CPU is awesome.
But previous owner plugged i5-3380M - is hot stuff!
And I, of course, decided to upgrade the cooling system. (for future cpu upgrade)
I find, in used goods shop, acceptable heatsink and cooler. Heatsink Toshiba satellite A100-192 (if believe to sticker name), cooler acer aspire 3610 F581-CW
The next steps:
1. expel hdd from his home, internal place. Now he will live in dvdrom bay)
2. remove some millimeters of steel (as more - as better) from native heatsink for better thermal contact. And cut off a layer from second heatsink. Second big reason - is very small space between lid and heatsink.
3. glued the second heatsink on thermal glue (for best fixation) and thermal grease in center of origin radiator.
4. Resistor 2W, 33 Ohm(in my case) connected to sata modified power connector and ---> cooler. It danger place, because strongly "upgraded" sata adapter may contact metal (non isolated) to heatsink and kill them all, if you don’t trim it carefully.
Results: before: from up to 90 degrees celsius under stresstest, After: temperature lower to 80 maximum value. Not sure about i7 :-)
Two large minuses:
1. No warm air output from notebook, for this second coolant system. Only air circulation inside case.
2. No much space between lid and heatsink in some contact points. Tight touch. It plus for cooling(of course, lid will be like heatsink) but, if you drop notebook, it may damage cpu and socket/MB.
P.S. sorry for my english.
