I got this Apache EP-CD901 fan Right now, my computer is running without any processor fan, so thats why I need this installed correctly and fast. Before this, I just installed the regular fan that the Intel processor came with. This fan comes with a Fan and a lil packet that says Heatsink Compounds. and 4 screws. I have no idea what that Compound stuff is, and would like to know where to put it. Thanks.
