I have the GIGABYTE GA-990FXA-UD3 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard and the AMD FX-8350 CPU and I'm pretty sure they're compatible. But I couldn't fit the fan onto the motherboard for the life of me. I actually ended up breaking the CPU I pushed so hard but the latches were just a tiny bit too short. I'm returning my CPU for a new one, but I'm worried the same thing will happen. What's wrong?
