Hi. My first build so taking it carefully. I've got an Asus Q87t motherboard with an i7 4790 on it. I bought the L9i and was doing a mock up in a Chopin case. When I put the cooler on the CPU, I can see that the heat sink block is in contact with the top of the top of the CPU i.e. nothing interfering. The feet of the bracket sit a few mm above the motherboard. This means that it I don't carefully do the screws up evenly, the heatsink does not sit flat. It also means that if I were to do the screws up tight it feels like it would put quite a lot of pressure on the motherboard. Is it normal to have a gap this big?
