Instructions are not very clear leading to some confusion, the CPU block had lots of cables coming off it that are very unnecessary and ugly and it was painted after the threads were made meaning none of the screws would go in without alot of hassle. Plus a bad design having radiator fins on the back side of where the screws go lead to a tone of problems installing the fans and rad to the case. The only option was to have the fans above the rad and then using the long screws to go though the top of the case though the fans and then into the rad and still with them as tight as they will go there is still some room for the fans to move meaning it should be tighter.
Bad design and bad introductions
