All are light and can be removed without using any tool.Two CT140 PC-fans pre-installedThe Tower 300 has two 140-mm PWM-fans on the top side, which provide for a good cooling power.Select the type of installationOn the right side, The Tower 300 can accommodate either three 120/140mm fans or one 420mm/360mm AIO radiator. The installation is very easy thanks to the removable fan bracket, which simplifies the process.Air inlet and outletThe Tower 300 has a vertical chassis design with well-designed cold air inlets and hot air outlets to keep the interior temperature low at all times.We've tested everything so you don't have to do itAt Thermaltake, we always test our products in tough conditions to ensure product quality. The Tower 300 products were tested for 30 minutes at 100% full load, with the best CPU, GPU and motherboard at the time of testing, while we are working with a consumer-style setup to test how the chassis behaves in real-world conditions.Massive air flow & unbelievable powerThe thermal images were taken during the heat test. Thanks to the two pre-installed CT140 PC fans, we were able to ensure The Tower 300 has massive airflow that provides amazing cooling performance and low internal temperature using the highest quality components.Perfect protection against dustThe Tower 300 has well thought-out filters on the top, the back, the inside and the inner floor, in order to protect the system from dust.Excellent hardware support & cooling solutionsThe Tower 300 offers a good hardware support. It can support a CPU cooler with a maximum height of 210 mm, a GPU with a maximum length of 400 mm (without PSU cover), a power supply with a length of up to 220 mm, three 2.5 SSDs or three 3.5 HDDs in total. Two CT140 fans are pre-installed on the top of the chassis to improve thermal efficiency. An additional 120 mm or 140 mm fan can be installed on top of the power supply cover, and up to a 420 mm/360 mm AIO CPU cooler can be installed on the right side of the chassis for maximum cooling.Convenient I/O portsA USB 3.2 (Gen 2) Type C and two USB 3.0 ports are located on the top to provide direct access when required.DMD: Removable modular designNo more unreachable screw corners or gaps, installation can be a breeze with our modular design that can be disassembled.This text is machine translated.
