Cooler Master HAF 700 EVO

The Cooler Master HAF 700 EVO describes itself as the ‘pinnacle of Cooler Master’s HAF Legacy’, and it lives up to that title with some truly top-of-the-class specs. It comes with dual 200mm Sickleflow PWM fans, both tailored to maximize the performance whilst keeping temperatures and noise levels low – even in extreme overclocking scenarios. Alongside these, it can support up to 20 (!!) 120mm fans, and 490mm GPU clearance. There’s enough space for two PC builds inside there, in fact. As for the outside, the front panel features an LCD display, and sleek ARGB tempered glass intake blades for stunning futuristic lighting.

Pros 

  • LCD display assistant and ARGB blades
  • 490mm GPU clearance
  • Two included fans and 20 fan capacity

Corsair iCUE 5000D RGB

The Corsair iCUE 5000D RGB provides out-of-the-box cooling and RGB lighting for your RTX 4090 build, with three AF120 RGB ELITE PWM fans and an iCUE Lighting Node PRO RGB lighting controller included. The spacious interior fits up to 12x 120mm or 4x 140mm cooling fans, along with multiple radiators including a 360mm in front and a 360mm push/pull in the roof. Plus, it fits even the biggest GPUs; there’s 420mm clearance. Meanwhile, two additional 120mm fan mounts on the PSU shroud allow you to install fans for direct airflow to the GPU. Oh, and did we mention the RGBs?

Pros 

  • Funky RGB lighting included
  • Up to 12 cooling fans
  • 420mm clearance

Cons

  • More expensive

Verdict

The Corsair iCUE 5000D might be a little pricier than other cases on this list, but it’s by far our best case for RTX 4090 builds that use RGB lights or LEDs. Plenty of RGB-focussed cases on the market are gaudy or cheap-looking, but the Corsair has a real air of luxury – in fact, the price seems almost reassuring in this context. The large clearance is also a welcome surprise, and the twelve fans is deeply impressive too.

Thermaltake Core P3 TG Pro

The Thermaltake Core P3 TG Pro’s recessed radiator, AIO, and storage mounting design gives you much more space for long GPU card mounting – ideal for bulky cards like the NVIDIA RTX4090. It supports VGA lengths of up to 330mm (with reservoir) or 450mm (without reservoir), which is impressively large for the size of the unit. On top of the original high-ventilation open-frame structure you’d expect from the Core P3 series, the P3 TG Pro also offers a new design mounting bracket so you can concentrate fan power on the GPU. The PCI-E slot itself is rotatable, and you can choose between 3 placement layouts: wall mount, horizontal, and vertical.

Pros

  • 450mm maximum clearance
  • High-ventilation open-frame structure
  • Multiple placement layouts

Cons

  • Only supports six fans

Verdict

The Thermaltake Core P3 TG Pro takes all the features of the previous Thermaltake models (large housing, open structure, sleek aesthetics), and takes them up to the next level. This is our best case for RTX 4090 in the open frame class, and makes a great choice for builders who want to get a good look at the internal workings of their PC in action. Although it only supports six fans at the most, the open structure gives enough ventilation that this shouldn’t be an issue.

NZXT H7 Flow RGB

The NZXT H7 Flow RGB is designed with airflow in mind. Perforated front and top panels direct filtered air through the case to cool down the components and enhance performance, whilst an angled 120mm fan draws air from below the case to provide direct cooling for your power-hungry 4090 graphics card. There’s even more space for radiators on top of all these super-cooling features: you can fit a 360mm radiator in the top and front panels, three 140mm fans in the front, and a 140mm fan in the rear. To top it all off, the kit includes three pre-installed F140 RGB Core fans that connect to a standard 5V ARGB header. Pretty colors!

Pros

  • Three pre-installed ARGB fans
  • 400m GPU clearance
  • Spacious cooling support and excellent airflow

Cons

  • Doesn’t support E-ATX motherboards

Verdict

Most of what we had to say for the NZXT H7 Flow RGB has been about fans – and the clue’s in the name, because this PC case is all about that Flow. This is our best case for RTX 4090 in terms of airflow, protecting your GPU with a low-temp, continuously refreshing blanket of cooling air. It’s impressively spacious, too, which really helps keep temperatures down and combat overheating.

Lian Li O11 Dynamic Mini

The Lian Li O11 Dynamic Mini offers 395mm of GPU clearance and a ton of cool features. You can fit up to nine fans on the side, top, bottom and rear for all-around airflow, and the tempered glass panels release heat whilst exposing the intricate internal workings of your PC. The aluminium elements keep things looking and feeling cool, too. You have multiple options for build configuration due to the case’s modular two-chamber structure – although this does make it a little more difficult to construct. Three USB-ports finish up the whole setup. Lastly, it comes in a range of colour options: snow white, anthracite black, and cool gray.

Pros

  • Nine cooling fan slots
  • 395mm GPU clearance
  • Modular two-chamber structure

Cons

  • Fiddly to construct

Verdict

Looking at the size of the NVIDIA RTX 4090, you might be thinking that the best case for 4090 would have to be big and bulky too. Luckily for you, the Lian Li O11 Dynamic Mini fits all the features you need – fans, water pump space, multiple modular configurations and more – in a surprisingly small package. If you want to make your PC look and run cool whilst staying compact, this is the best case for RTX 4090 for you.
