I am currently building a system, and just recieved my motherboard and AMD Athlon XP CPU along with fan. I installed the Motherboard then installed the cpu and went on to install the fan. I followed the instructions and looked at the illustrations from the back of the fan retail box.I applied the thermal grease under the fan, once i tried to put the fan in I got some thermal grease ontop of the CPU, some on the core, and some on the little metal thingies next to the core. Its not alot but it is visible. I'm worried now, and wondering if I destroyed or ruined anything. I'm pretty much new to this so I'm looking for some input from experienced people. I can't test out the system either because I don't have all the parts yet.
