My computer have 2 fans one is cpu fan which spins 2009rpm (i looked at speedfan) and the sys fan which speed is 0rpm, and i looked at my computer box and saw that it spins but like not at max speed, like 20%, so how can i speed it up , because i cant play any game or watch some hd videos because my computer shuts down by it self. speedfan and afterburner doesnt work.
