The main difference between the NZXT H5 Flow RGB and the NZXT H5 Flow lies in several key areas: ## Fans and airflow - The NZXT H5 Flow comes with two 120mm fans that have a 3-pin connector and a fixed speed of about 1200 RPM. These fans are quiet and produce about 25.1 decibels of noise. - The NZXT H5 Flow RGB, on the other hand, comes with four fans, including two additional 140mm RGB fans, which also have a 3-pin connector and a speed of 1200 RPM. These fans are slightly louder at around 30 decibels of noise. ## RGB lighting - The H5 Flow RGB includes RGB fans that provide lighting, while the H5 Flow does not have RGB lighting. The RGB fans of the H5 Flow RGB require a connection to a 5-volt RGB header on the motherboard to control the lighting. ## Price and value - The H5 Flow RGB is more expensive than the H5 Flow, but offers more fans and RGB lighting. The H5 Flow is less expensive and offers good airflow performance without the added features of the RGB model. ## General specifications - Both models have the same dimensions, the same motherboard compatibility (ATX, EATX, Micro ATX, Mini ITX) and the same connectors on the front panel (USB 3.2 Gen 1 Type A, USB 3.2 Gen 2 Type C).

Yes, you can also use the fans of the H5 Flow RGB without an RGB controller. The supplied fans, such as the F360 RGB Core (CV) and the F120Q (CV), each have a single power connection and can be connected directly to the motherboard or to a separate fan controller without the need for an RGB controller.

The NZXT H5 Flow RGB (ATX) case comes with a total of four fans pre-installed: - Two RGB fans at the front, which can be controlled via the motherboard's ARGB header. - One non-RGB fan at the rear. - One angled 120mm fan at the bottom, which is specifically designed to cool the graphics card. The case is compatible with the Gigabyte B550 AORUS Elite V2 motherboard, as it supports ATX, Micro-ATX and Mini-ITX motherboards.
