Are Thermaltake fans quiet? Their spec tables say 21.2 to 35.3 dB-A

One dB-A number per fan

A CT120's table says "Noise 25.8 dB-A", printed beside a speed range but never tied to a speed, distance or standard. That is the pattern on every fan.

The row sits in each product's spec table with Dimension, Fan Speed, Max Air Pressure, Max Air Flow, Bearing Type and Life Expectation. Cooler pages call it "Acoustical Noise", and AIO pages tuck "Noise Level" inside a Fan row. Even the unit wanders: "dB-A" on most fans, "dBA" on coolers, "db-a" on the TOUGHFAN 12 2-pack and "dBa" on the Gravity i3. All of them are read here as A-weighted decibels, as the spelling suggests.

Has Thermaltake said how it measures fan noise?

Once. The Riing Silent 12 cooler page says it "was tested in a semi-anechoic chamber which includes anti-vibration, sound-proof, and sound-absorbing effect". No fan page we opened names a chamber, microphone distance or standard.

With a single number beside a speed range, the natural reading puts it at the top of that range. Thermaltake never confirms it. The CT200's table, for example, pairs its 27.2 dB-A with a 500 to 900 RPM range.

So the figures rank Thermaltake fans against each other well and against other brands badly. Comparing decibel ratings explains why unstated conditions undermine cross-brand comparisons.

What is the quietest Thermaltake 120mm fan?

By its spec table, the TOUGHFAN 12 RGB at 21.2 dB-A. It was unavailable. The TOUGHFAN 12, at 22.3, is the lowest PWM fan that was in stock on Amazon.

Each row gives the figure with stock blades, the top speed, the most airflow Thermaltake lists, and the US store price on November 8, 2026.

Two fans stay off that list. The SWAFAN GT12, $29.99, ships three blade types and prints a figure for each, 26.5 dB-A with its high air pressure blade, 28.3 with its high air flow blade and 29.8 reversed, and none is named as the stock blade. The LE120 ARGB Sync, $29.99, has no Noise row in a spec table at all; its feature panel says "Noise Level 25.2 dBA".

Thermaltake's 120mm fans sit beside Noctua's and ARCTIC's in our 120mm fan guide.

The 140mm range runs from 26.1 to 35.3 dB-A

Lowest among those available to order was the Riing Quad 14 RGB single, 26.1 dB-A at 1400 RPM. Among fans in stock on Amazon, the SWAFAN 140 EX INFINITY leads at 28.1.

The Riing Duo 14 (26.2 dB-A), Riing Trio 14 (26.5) and Riing Plus 14 (27.2) were unavailable. The SWAFAN GT14, $34.99, prints 34.3, 32.7 and 36.1 dB-A for its three blade types. Noctua, be quiet! and other 140mm rivals appear in our 140mm case fan rankings.

For 200mm slots, the CT200 lists 27.2 dB-A at 900 RPM for $19.99 and the Pure 20 28.2 at 800 RPM for $13.99.

Reverse blades always print higher

Every Thermaltake fan sold with reverse blades prints a higher figure for them, from 1.9 dB-A more on the SWAFAN EX12 to 7.2 dB-A more on the TOUGHFAN EX12 Pro.

What the swap buys is direction. The TOUGHFAN EX12 Pro copy says the reverse blades "can bring air from the back to the front", so the frame keeps facing the same way while the airflow flips, and the cost is a louder figure. Fixed reverse fans follow the same pattern: the CT120 EX Reverse prints 31.2 against 28.5 for the CT120 EX.

Which Thermaltake CPU air cooler is quietest?

The Riing Silent 12, at 18 ±1 dBA. It is a 150 W design, though, with manuals dated 2016. Among current towers the TOUGHAIR 110, 310 and 510 share the lowest figure, 23.6 dBA.

The Engine 27, unavailable, prints a range, "13-25 dBA", so it is quoted rather than ranked. The UX100 lists 26.92 dBA on Thermaltake's global page but was unavailable in the US store. Noctua, be quiet! and DeepCool coolers are compared in our CPU cooler rankings.

How loud is a Thermaltake AIO liquid cooler?

With stock blades, 22.3 to 37.8 dB-A in the Fan row of the spec table. That figure covers the bundled fans only. No current AIO page we opened gives a pump figure.

The Floe Riing RGB 240 and 360 print a range, "19.8~24.7 dB-A", and the Floe DX RGB 360 "19 ~ 23.9 dB-A", so they are left unranked. The Floe RC240 and Floe RC Ultra pages print no noise row. Thermaltake's coolers face other brands in our AIO cooler guide.

A TH V2 cooler's figure is really a CT120's

The fan row on a TH V2 cooler repeats the CT120's spec line exactly: 25.8 dB-A, 57.05 CFM and 2.23 mm-H2O. Other coolers do the same. The TOUGHLIQUID EX Pro and AW360 print 22.6 dB-A with 70.8 CFM and 3.19 mm-H2O, the TOUGHFAN 12 Pro's figures, and the MINECUBE 360 Ultra and MAGFloe 360 Ultra print 30.6 and 32.5, the SWAFAN EX12's standard and reverse figures.

That makes the cooler figure useful for one thing: it tells you which fans are in the box.

Pump, screen and radiator size change nothing in that number.

V3 coolers trade 12 dB-A for airflow

Every TH V3 and TH-S V3 cooler, plus the Retro Ultra and ST360 Ultra, prints "Noise Level : 37.8 dB-A (per fan)", the highest stock-blade figure on any current Thermaltake AIO.

The V3 coolers use what Thermaltake calls a "single-frame fan design", spinning from 500 to 2500 RPM, 500 RPM faster at the top than the V2's 2000. The TH360 V3 Ultra's spec table lists 85.29 CFM per fan, against 57.05 for the V2 fans. Twelve dB-A more buys more airflow. Oddly, the louder cooler is the cheaper one: a TH360 V3 at $99.99 costs $30 less than a TH360 V2 ARGB Sync.

Pages that disagree with themselves

A handful of Thermaltake pages print two different figures for one product, or put a value in the wrong row. The spec table wins each time here.
