I am Asian American and my English was keep learning now,
I been bought two cases of w230st from AMERICAN.i had refiting "heatsink"after I've noticed the thermolysis wasn't good as long as while I playing 3D GAMES.
therefore I been seeking new heatsink and fan which could better fit on motherboard
After I exchanged the main 2.5"SATA HDD to 1.2"SMATA
I chosen Lenovo and Dell's fans finally,it is the closest model that i been seeing during a month
those are my effort ,please left question if you cant understand.hope you'll like it
