Hello. I have a 3 years old motherboard MSI Z87-G43 and i7 4770k. The CPU cooler is Zalman Performa 10. While replacing thermal paste on my CPU today I noticed that I have 3 bent pins in left down corner... I have no idea how and when they were bent. Was it manufacturing defect? Was it my fault? Or maybe these 3 pins were supposed to be bent? Because they were bent really accurate. Please help me! I don't know what to do. I figure out that I'll ask here before doing anything stupid. My PC boots without any issues and I even passed 1 hour linx stability test. I don't have a good camera, but here is some pictures:

All other pins are fine, but only these are bent. Every accurate like they are supposed to be... But they are not, right?..
