120 mm all-in-one liquid cooler

The Thermaltake TH120 ARGB Snow Edition is a closed-loop liquid cooler built around a single 120 mm radiator and a 120 mm ARGB fan. It targets builders who want a compact cooling solution for mainstream Intel or AMD sockets without a custom loop. The white Snow finish and addressable lighting suit colour-coordinated builds.

Upgrade path from stock air coolers

This unit replaces basic boxed air coolers when lower noise or tighter clearances are priorities. The jump is worth it if your current cooler hits thermal limits under sustained loads or blocks memory slots. The 1500 RPM fan delivers 59.28 CFM at 28.2 dB-A, offering more headroom than most stock fans.

Clearance and header checklist

Verify that your case can mount a 153 x 120 x 27 mm radiator with a 25 mm fan. Confirm the CPU block clears nearby components; the copper base and pump add height over the socket. Ensure your motherboard has a 5 V 3-pin ARGB header (2510 connector) for sync, or use the included controller. The 400 mm tubes must reach from the CPU socket to the chosen radiator location.

Questions about this item

Will the 153 x 120 x 27 mm radiator and 400 mm tubes fit my case?

The radiator measures 153 by 120 by 27 mm and the tubes are 400 mm long; verify your case supports a 120 mm radiator and that the routing path accommodates the tube length.

Which headers do the 3-pin 2510 fan connector and the 5 V 3-pin ARGB lead plug into?

Attach the fan to a motherboard fan header using its 3-pin 2510 connector and connect the ARGB cable to a 5 V 3-pin addressable RGB header; if the board lacks one, use the included controller.

Do the rubber tubes or the copper cold plate need periodic replacement?

The rubber tubes and copper cold plate are sealed inside the loop and are not user-serviceable; no scheduled replacement is required.
