Cooler Master Cosmos SE Case Review

Cooling And Dust Protection

Cooler Master's Cosmos SE sports an easily removable dust filter in the front. Behind it, two 12 cm fans (Cooler Master A12025-12CB-3DN-F1) pull air into the enclosure. The fans feature blue LEDs you can turn on or keep off. Rubber rings decoupling the fans from the chassis are glued into place at the factory.

Consequently, the fans are attached with custom-made, longer screws. Some of the cases that went out to reviewers had problems with threading, but Cooler Master assures us that those issues were fixed on all retail models. Of course, if you've experienced any different, let us know in the comments.

If you want even more airflow, two additional 12 cm fans can be fitted to the hard drive cage in a similar fashion. Again, the custom-length screws and decoupling rubber pieces come bundled with the case.

The top of the enclosure also sports a dust filter. It can be removed by unfastening a thumb screw on the back of the case and then pulling it out. A 14 cm fan (Cooler Master A14025-12CB-3BN-F1) is installed underneath. There’s space for up to two 12 or 14 cm fans, though a second fan makes the top 5.25-inch drive bay unusable for anything except components that don’t reach far into the case.

Another 12 cm fan (Cooler Master A12025-12CB-3JN-F1) rounds out the factory-installed complement of coolers. All of the bundled fans hum along at 1200 RPM, and only the two front ones are decoupled from the chassis. They're powered either in series through a four-pin Molex connector or separately with three-pin headers that attach to a fan controller or the motherboard. Unfortunately, the Cosmos SE doesn’t come with its own fan controller.

Two more dust filters are resident on the bottom of the Cosmos SE, mounted externally close to the power supply and hard drive cages. If you need to clean them, they can be pulled out toward the front and back. One more thing: the rubber feet that this chassis stands on are screwed, and not just glued into place.

The hard drive cages can be removed, but only at the cost of the fans that are installed on them. It’s simply not possible to get rid of the drive cage elements and retain the fans for a better overall airflow. An alternate option for installing the coolers, maybe attached to the rails for the radiator installation, would have been nice.

Water Cooling

As usual, a 12 cm radiator fits on the back of the case. In addition, there’s space for 28 and 36 cm radiators at the top and the front, respectively.

Additional fans with the usual frame depth of 2.5 cm can be screwed onto the case directly, and fit between the top part of its metal frame and top cover without any problems. There are also holes for the fans' power cables.

The screw holes for the radiator could have been a bit more toward the side of the case to avoid collisions between tall CPU coolers and thick radiators (or radiators with fans on both sides). Finally, we should point out that 24 cm radiators will block most of the top 5.25-inch drive bay.

Installing a radiator on the front of the case has its own drawbacks. If you use a 24 or 28 cm product, then you have to either forgo all of the hard drive bays, or unscrew and remove the 5.25-inch drive cage and retain use of the bottommost two bays.

Either way, the previously-mentioned retention rails are used for the installation. A push/pull configuration is possible if the radiator with its fans is screwed onto the front of the rails.

    Why put "carrying handles" on a 10KG (when empty) case? IMHO they are useless and add to the total weight and from my experience, when you have finished assembling your new PC you add approximately 5KG to the weight of the case. 15Kgs with carrying handles...

    The handles, more or less adds to the look, and strangely enough, some guys take theirs to a Lan party. I once read a review where some guy complained about not having a way to carry his Corsair 800D around to Lan parties,and complained about the case feet breaking off. So there's some numbskulls out there that can't seem to figure it out for themselves...The way I see it, in the case you need to move your case around, at least you have them. You may not want to move it around all the time, but it's better to have them and not need them, than to need them and find your back thrown out of whack because of lifting it without them.

    No one is forcing you to get this one with carry handles... CM and others provide you with plenty of choice. I for one would prefer to have them on quality case. Even if I have to move it only few times a year ( I have CM Storm Scout ).I say bless that handle it's so much easier to pick up and move around, and I have one hand free to open doors grab cables whatever. I is just very convenient.

    P.S. 15 kg one handed should not be a problem for you, bro do you even lift ? ;-D

    I am actually quite glad this review is out, I bought this just last week. I got all my components in!

    Also, it is 10.8 KG. The handles do help a tonne.

    I never really got the point of putting front fans in a case whose airflow is immediately blocked by HDD bays or mounts turned sideways (even those not occupied due to design). I understand turning the mounts saves space in the depth direction, but completely blocks the intake's airflow. This is why I think it is key for any advanced case to be designed to allow you to remove the HDD bays that aren't in use. Why even bother with fans whose output has to pass through a bunch of obstacles? This renders the intake of airflow virtually ineffective.

    This case needs a REV.2 with that 3rd optical issue solved. waiting for it. either that or the new fantastic corsair graphite 760T...decisions... decisions...

    "The screw holes for the radiator could have been a bit more toward the side of the case to avoid collisions between tall CPU coolers and thick radiators (or radiators with fans on both sides)."

    Is it not the idea of using radiators is to avoid using tall CPU coolers? The biggest concern for watercooling in regards to the top radiator mount is clearing the tall memory heatsinks that some memory manufacturers use.
