Floe DX 280 liquid CPU cooler

The Thermaltake Floe DX 280 is an all-in-one liquid CPU cooler built for mainstream Intel and AMD platforms. It combines a high-performance copper base plate with a 312 mm aluminium radiator and two 140 mm Riing Duo fans. Addressable RGB lighting on both the waterblock and fans lets builders customise colours through software.

Sustained-load thermal behaviour

Under continuous load the hydraulic-bearing fans operate between 500 and 1400 RPM, delivering up to 60.87 CFM while noise stays between 19.8 and 26.2 dB-A. The pump and radiator are designed to maintain steady coolant flow so temperatures remain stable during extended gaming or rendering sessions without sudden spikes.

Installation experience and common issues

The package includes mounting hardware for Intel sockets from LGA 1150 through LGA 2066 and AMD sockets from AM2 through AM4, but LGA 1700 brackets are not supplied and must be requested from the manufacturer. The 326 mm rubber tubes limit routing options in compact cases, and the 9-pin fan connector requires a compatible header or adapter on the motherboard.

Questions about this item

How loud are the 140 mm Riing Duo fans when the pump runs at full speed all day?

The hydraulic-bearing fans operate between 19.8 and 26.2 dB-A across their 500 to 1400 RPM range, so even at maximum airflow they stay in the quiet-to-moderate bracket for an all-day load.

Which mounting brackets must I already have to install the water block on an LGA 1700 board?

The package includes brackets for LGA 1700, 1200, 115x, 2066, 2011-3 and 2011 plus AMD AM4, AM3(+), AM2(+) and FM2/1; extra LGA 1700 brackets are not included and must be sourced from the manufacturer.

Will the 312 mm radiator and 326 mm tubes fit alongside a full-length graphics card in a standard mid-tower case?

The 312 × 120 × 27 mm radiator needs two 140 mm fan slots at the top or front; with 326 mm tubing you have enough reach for most mid-tower layouts, but verify your case’s radiator clearance and GPU length before buying.
