A Closer Look - Inside

Removing the glass and the side panel, you have great access to the interior of the FSP M580 Plus while also revealing the three reverse bladed intake fans on the side. The only branding you will find is on the interior of the case on the bottom of the front edge of the case. This should appease system integrators, as those will want their own branding to be predominant when offering full systems.


At the backside of the motherboard, you will find a storage mounting plate which you will have to remove to gain access to the interior during assembly and cable management. Once removed, you can clearly see the openings for the BTF connectors as well as cable management. It would have been great to see grommets on the openings on the top and side. While the ones on the side are shared with BTF connections, you will end up seeing all of those when viewing the case from the front when the system is fully assembled.


Thanks to the use of the fans with pass-through connectors built-into the frames, you only have to deal with two sets of wires: one for the three intake fans on the side and one for the exhaust fan in the back. These are both connected to a PCB which is firmly secured on the floor of the M580 Plus. It is interesting to see the eight PWM and ARGB headers being upright, as this does actually make using these a bit easier while also allowing for space to access any potential BTF interfaces as well. Above that, in the rear, the PSU bay is pretty straightforward, with two metal lips to sit on. There is very little room for cable management, so you will only really be able to route skinny cables down the right side of the motherboard CPU cooler opening.


The three intake fans on the side sport reversed blades. The frame of these is a bit thicker, which means the air intake is smaller. These fans are 30 mm thick, which traditionally translates into deeper blades which can move air better. On top of that, unlike the M580 Non-Plus variant, these fans are all connected to each other with that single sleeved pair of wires running across the bottom. Initially we wanted to flip this stack over, so that the cable could be run across the ceiling, but these fans also sport an RPM display on top of the embedded ARGB elements, thus the out-of-the-box configuration is what you want.


On the floor, you may install three more 120 mm fans with a good gap towards the motherboard, meaning that any headers on the bottom edge of your board will not be blocked with those cooling units installed. At the very front position, you may install one more 3.5" drive instead of a fan and upon closer inspection there is one more 2.5" placement possibility as well. While the fans may rest on the floor, there is a bit of flexibility to slide the stack upward, giving you the needed clearance for an SSD.


In the rear, the seven expansion slots come with vented covers and that fourth included fan in the rear has its blade in the traditional direction, so that this one pushes air out the back. Similarly to the ones in the side, the connector for the cables of this fan are not in the ideal spot, but this is the way to make sure the display is visible properly as well.


In the ceiling of the FSP M580 Plus, any cooling you install should fit well without interfering with your motherboard or tall memory. Thanks to the mounting cutouts a 360 mm unit will be as far away from everything as well, which will help with cable management.


All the cables within the M580 Plus are black and both the USB-A and USB-C wires use flat-band wiring which makes cable management much easier. The front panel connectors have been unified in a single header to top things off, so the chassis does everything right when it comes to its wiring.


Before we dive into the installation, these fans deserve a closer look. Being that thick and chunky, the display is embedded in the corner of the frame opposite of the modular input. As you can see, both wires for PWM and ARGB are sleeved black and the ARGB elements are present on both sides of the fan, so no matter how you install it, that illumination can be seen perfectly. Lastly, as an added measure, the fan has infinity mirror sides.


The connector uses six pins, which is something we sometimes see on more affordable ARGB fans, but in this scenario that is just used to interface with the unit. The plug has a peg on it, so you can only plug it into one of the two ports, with the one lacking such a hole meant to be the daisy chain to other fans.
