Manufacturer description

The Thermaltake Floe DX 240mm is an all-in-one liquid CPU cooler built around a copper water block and a 240mm radiator, paired with two Ring Duo 120mm fans that carry 18 addressable LED zones across the block and fan rings. Those fans spin from 500 to 1500 RPM on self-lubricating hydraulic bearings, rated at 19 to 23.9 dB-A with up to 42.45 CFM of airflow each, so you can trade noise for heat dissipation depending on load. The pump runs at 3600 RPM. Lighting and fan curves are handled through Thermaltake's TT RGB Plus software, which also syncs with Razer Chroma via Synapse 3 and accepts…

SpecPicks Verdict

SpecPicks scored Thermaltake Floe DX 240mm using a rating × review-volume × price-fit model applied to published specs and reviews across the cooling & fans category. Thermaltake's cooling & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

Does the Thermaltake Floe DX 240 work with LGA1700 or AM5?

AM5 and AM4 are supported out of the box. LGA1700 needs the separate Thermaltake LGA1700 kit, P/N CL-O032-PL00BL-A (ASIN B09LLYRWDQ), which is sold separately.

How loud is the Floe DX 240mm?

Thermaltake rates the 120mm Ring Duo fans at 19 to 23.9 dB-A across their 500-1500 RPM PWM range, with up to 42.45 CFM airflow per fan at the top of that range.

Can I control the RGB without installing software?

Full 18-zone control runs through the TT RGB Plus software. For motherboard-driven control, you need the TT Sync controller (CL-O015-PL00BL-A) to link it to 5V addressable RGB headers on select Gigabyte, MSI, and ASRock boards.

Does it sync with Razer Chroma?

Yes. TT RGB Plus integrates with Razer Synapse 3, so the water block and fan rings can match lighting effects across Chroma-enabled peripherals.

Can I run a push-pull fan setup on this radiator?

Yes, the radiator is designed to support push-pull configurations for extra heat dissipation. You supply the second pair of 120mm fans; only the two Ring Duo fans are included.
