Crunching sound when installing i5?

When I lower the bar on the cpu scket, a kind of hissing sound happens, kind of sounds like the pins are bending-is this normal? They are both brand new.
I read that this is normal, is that true?

  1. Not that I heard when I assembled my Haswell, but you can only go in one direction; if it boots its probably fine.
    You cant send it back if you dont turn it on and if the damage is done it wont make any difference; as long as you put the socket gaurd back your covered.

    The socket fingers are angled ~30 degrees and as they get compressed, they may slip/scratch a little across the LGA pads and cause faint metallic creaking sound. The CPU may also move around slightly (the socket keys have maybe 0.1mm of slack to them) and add to that noise. The pressure plate mechanism itself may also cause similar noises due to friction and flex in the mechanism.

    So a little bit of noise is normal.

    OMG THNAK YOU SO MUCH I was about to cry I broke my last cpu and had to get it returned and replaced o.O
    Did not want to raise the death count any higher. So a crackling sound is 100% normal? I installed the cpu a week before the rest of the parts will come, so I cant test it. Was that a bad idea?

    As I said, a LITTLE bit of noise is normal. If you installed it correctly, the pressure plate should have effortlessly started engaging the retention pin and then have fairly uniform movement/force from the moment the plate "catches" on the pin until the lever reaches the locked position.

    As for installing the CPU before getting the rest of your parts being a good/bad idea, the CPU is safest in its original packaging but now that it is in the board, leaving there is safer than removing it.
