Hey guys, I bought a Compaq laptop that is part of the r4000 series back in May and around August the cpu fan started making annoying grinding sounds. If I lightly tilt the laptop back and forth, it will stop, but soon enought the grinding sound will kick in again. I bought the laptop from Newegg and was wondering if it would be safe enough for me to fix myself. Should I buy a new heatsink fan or what? Or will Compaq fix it?
