Antec Dark Fleet DF600 Flux – The Flux cooling concept in test

With the Dark Fleet DF600 Flux, Antec offers a case that uses the new F-LUX (Flow Luxury) cooling concept. With the new F-LUX platform, Antec promises a new and highly efficient design that offers maximum airflow and is specifically designed to help cool the GPU. Whether and how the new design affects the cooling performance and what pitfalls the case has in store for us, we found out for you in our review.

Scope of delivery

In addition to the four fans already pre-installed in the case (three of which are illuminated), another fan is included for mounting on the PSU cover. The extra fan has had the blades reversed so that it can be installed face up and still blow air into the case. Also included is another small package that hides inside the HDD cage. Inside is the installation instructions, several cable ties, two Velcro cable ties with an Antec imprint, and various screws, which are all packed in a bag.

External impression

Looking at the front, the three pre-installed RGB fans immediately catch your eye. These are covered by a transparent, let’s call it “plastic bridge”. The Antec logo has been placed in the lower area of the transparent plastic. Fresh air is sucked through the slits, between black and transparent plastic, and then gets inside. A dust filter in front of the fans has been omitted, which benefits the look of the front. The entire front panel can be removed by simply pulling it forward and you get full access to the fans. By the way, the front offers space for up to three 140 mm fans.

If you look at the DF600 from above, you will immediately notice the extremely lushly designed dust filter. This is, as usual with most cases nowadays, attached to the case with a magnetic tape. This means that radiators have also been taken into consideration, the waste heat can escape well through the perforated lid and there is no heat buildup. In the lid, we are offered mounting options, for radiators with a length of up to 360 mm. We also find the front connectors here again, these are installed on the right side. Antec has provided the DF600 with two USB-A 3.0 ports, as well as the typical jacks for headphones and microphone. Unfortunately, we completely miss a USB-C port. Next to the power button is another button to control the illumination of the individual fans.

We don’t really expect any big surprises in the rear area. The case has seven PCI panels on offer, so we don’t have to worry about missing PCI Express slots. The power supply is installed at the bottom, but we also find the corresponding slot here.

On the right side panel, a small panel has been perforated in the lower area. This extra is part of the cooling concept and allows more fresh air to flow into the case. In order to have a protection against the nasty dust, Antec has also added another magnetic dust filter from the inside here.

On the bottom is the mounting for the HDD cage, as well as another dust filter for the PSU fan.


The interior is very clearly designed and kept in plain black. In the rear is the fourth fan already pre-installed, which unfortunately is not illuminated. The power supply cover offers enough cutouts for any connections at the bottom edge of the motherboard. This makes it very easy to feed cables through, which we liked. In addition, the PSU cover has two cutouts. One on the lower left edge to have a view on the PSU and the second cutout is in front of the front fans. This offers the possibility to install a radiator with a length of up to 360 mm. If you decide to install a radiator in the front, you unfortunately have to do without the dust grille. This is attached from the inside with magnets and the mounting holes are covered.

We would have liked to see a removable cover for the radiator opening, since it is difficult to hide the tangled cables, especially with non-modular power supplies. Unfortunately, we also have to do without rubberized cable grommets. Overall, the workmanship is very good and we can’t see any unevenness or critical areas. Even the choice of materials is okay and leaves little to be desired.

If you take a closer look at the back, you’ll immediately notice the fan controller, which has a not exactly pleasant surprise in store for the uninformed. The controller is supplied with power via a SATA port and also passes it on to the fans. There is no connection to the motherboard via a PWM signal. The fans therefore run at 100% power and that is really not bearable for anyone. So it is recommended to use a PWM splitter, like the Deepcool Fan Hub*. This offers connection options for up to 10 fans at the same time.

Lighting control via the controller again works very well. An explanation on how to connect to the motherboard is not included. However, Antec offers a information sheet for download on the product page for this purpose. If you don’t have a 3-pin ARGB connector on the motherboard, you can still control the lighting via the button in the front panel.

Installation and practice

For our review, we installed the following components in the Antec DF600:

The installation of our test system went very easily from the hand. There is plenty of room for the individual components to be safely installed. It’s recommended to mount the fan on the PSU cover towards the end, but before the graphics card. Since it could possibly cover the mainboard slots. You should also make sure to first connect the case connectors to the mainboard and only then insert the PSU. Otherwise, the cable entry will be blocked so that no plug fits through.

There are enough grommets and mounting options on the back for cable management. However, cable management becomes a real challenge when using seven fans and the additionally required fan lift. In combination with a non-modular power supply, it even becomes a medium disaster.

We noticed the attachment of the SSD slides in a positive way. They are simply put over the rubberized holders and locked down. It really couldn’t be simpler.

Performance test

For our performance test, we stressed our processor with the Prime95 stress test. To heat up the graphics card a bit, we loaded our GTX 1660 Super with the free FurMark stress test. The results will show whether the new airflow design works.

Fan Performance Temperature CPU ∅ (°C) Temperature GPU ∅ (°C)
5 V 67.4 66.0
12 V 58.0 65.0

In the performance test, the Antec DF600 Flux does quite well. The temperatures of the components used stay at a solid level and the components do not get too hot. At full fan speed, the fans are very audible and are even found to be quite annoying. You can see from the temperatures, especially of the graphics card, that the ventilation concept works. Even at low speeds, enough air gets into the case. Due to the extra fan on the PSU cover, the graphics card is always supplied with fresh cool air. So the luxurious airflow concept works exceptionally well!


In itself, Antec delivers a very successful case, at a quite reasonable price. Five case fans are already included in the scope of delivery, three of which are even equipped with RGB lighting. Visually, the DF600 blew us away. The transparent front and the fans behind it make the sight something special. The new airflow design is not bad and our components stay reliably cool.

However, we noticed a few negative things, such as the lack of fan control and the fact that you have to do without a dust filter as soon as you want to attach a radiator in the front. For sensitive ears, we recommend replacing the fans with quieter premium fans, such as the LL120 RGB case fans* from Corsair.

However, if you are aware of the listed points, you can safely grab the Antec DF600 Flux* and get a real eye-catcher on your desk!

Value for money


A really nice airflow case, which can score points with respectable optics. A fan controller is not included!
