Fan broke on computer. get a "guy" to replace it. Still doesn't work. "Guy" knows that it's the wrong fan but doesn't tell us. May have just voided our DELL warranty. "Guy" knows that but tells us he can't get that part here, in Fiji so he puts in the closest to it.
 Computer is wide open with a normal fan blowing on it. It keeps us cool but probably doesn't do much for the cpu. 
"Guy" is a hacker.
The end.
