My dad used to work for IBM and still has some stuff from their. He used to make super computers and servers I think. But I found this usual fan. I searched it up and it is apparently a CPU cooler. I wonder if I could use this in my rig with Phenom II X4 965 in my Cooler Master Elite 430 or use it for anything.
