Overview of the HAVN HS 420 and Fractal Design Define R5
The HAVN HS 420 is priced at £199.99, while the Fractal Design Define R5 is more budget-friendly at £114.65. This significant price difference reflects the distinct features and design philosophies of each case, catering to different user needs and preferences.
The HAVN HS 420 offers a hybrid design with unique features aimed at gamers and PC enthusiasts who prioritise aesthetics and cooling performance. In contrast, the Fractal Design Define R5 is designed for users seeking a silent computing experience without sacrificing airflow or expandability. Each case brings something different to the table, making this comparison essential for potential buyers.
Cooling Performance
Cooling capabilities are a standout feature in both the HAVN HS 420 and the Fractal Design Define R5, but they approach this aspect differently. The HAVN HS 420 supports up to eleven 140mm fans and accommodates three 420mm radiators, making it an exceptional choice for custom water cooling setups. This extensive cooling potential is ideal for high-performance builds that generate significant heat.
On the other hand, the Fractal Design Define R5 is also water-cooling ready, housing radiators of up to 420mm in the top and 360mm in the front. While it may not boast the same number of fan slots as the HAVN HS 420, it does include two Fractal Design Dynamic GP14 140mm fans designed for optimal airflow while maintaining low noise levels. This makes the Define R5 a solid choice for users who value both cooling and quiet operation.
Design and Aesthetics
In terms of design, the HAVN HS 420 features a heat-formed UniSheet glass panel, which provides an unobstructed view of the internals while minimising distortion. This sleek, innovative design is visually appealing for gamers who want to showcase their hardware.
Conversely, the Fractal Design Define R5 is focused on functionality, utilising high-density noise-reducing materials throughout the case. This helps to absorb sound while still allowing for effective airflow. The Define R5’s design prioritises a clean, minimalist aesthetic, making it suitable for users who appreciate a more understated look in their gaming or workstation setups.
Cable Management
The HAVN HS 420 excels in cable management with its Unique SimpliCable system, featuring integrated cable channels that ensure neat and organised routing. This attention to detail allows builders to achieve a cleaner look, which is especially important for showcasing high-end components through the tempered glass panel.
In contrast, the Fractal Design Define R5 is equipped with new tool-less ModuVent fan slot covers, allowing users to install additional fans as needed or keep certain slots covered for better sound absorption. While it may not have a dedicated cable management system like the HAVN HS 420, the Define R5 still offers flexibility in managing cabling, ensuring a tidy build.
Storage Options
When it comes to storage, the HAVN HS 420 offers a customisable interior that can accommodate various configurations for storage devices and cooling components. This flexibility is beneficial for users who may want to expand their system in the future.
The Fractal Design Define R5 stands out with its flexible storage options as well. It includes two dedicated SSD mounts behind the motherboard tray for tool-free installation and removal, as well as an adaptable HDD cage system that can hold up to eight 3.5” or 2.5” drives. This level of storage versatility makes the Define R5 an attractive option for users with extensive data needs.
Noise Levels
The Fractal Design Define R5 is specifically designed for silent computing, incorporating high-density noise-reducing material throughout the case. This makes it an excellent choice for users who prioritise a quiet environment, whether for gaming or professional work.
In contrast, the HAVN HS 420 does not emphasise noise reduction in its features. While it supports extensive cooling options, users may need to consider additional measures if quiet operation is a priority for them. Therefore, if silence is a critical factor in your choice, the Define R5 is likely the better option.
Target Audience
The HAVN HS 420 is aimed primarily at gamers and PC enthusiasts who desire a visually striking case with extensive cooling options and customisation features. Its design and capabilities cater to those looking to build high-performance systems that can handle demanding tasks and showcase their hardware.
Conversely, the Fractal Design Define R5 targets users who value a balance between performance and quiet operation. It is well-suited for both gamers and professionals who require a dependable case that can accommodate a variety of components without compromising on noise levels.
Which should you buy?
Choosing between the HAVN HS 420 and the Fractal Design Define R5 ultimately depends on your specific needs and preferences. If you are looking for a visually appealing case with extensive cooling capabilities and customisation options, the HAVN HS 420 at £199.99 is an excellent choice. However, if you prioritise silent operation and flexible storage options at a lower price of £114.65, the Fractal Design Define R5 would be the better option. Each case has its strengths, so consider what aspects are most important to your build before making a decision.
