The CPU Power Cable is not long enough to stretch. That is the furthest I can get it. Is that not safe?
I'd prefer the heatsink to not make contact with the RAM as well. I can't move the heat sink at all as there is only one position for it. The cooler fan is not touching the RAM. Only the most bottom metal plate of the heat sink is making contact with the very top of the 4th RAM.
You want the heatsink turned so the fan is over the ram. And it should not require a lot of force to screw in. Make sure the screw hole is clear and the screw is going in straight. The cpu wire might be better off not in the cable management hole and just running beside the mobo.
