Thermalright TL-C12C-S X3 3-Pack 120mm ARGB PWM CPU Cooler Fan Review: The Undisputed Champions of Budget ARGB?

I remember the final moments of my last PC build. The CPU was seated, the RAM clicked into place, and the graphics card was slotted in, gleaming under my desk lamp. It was a machine built for performance. But when I powered it on for the first time, I was met with two disappointing realities. First, the stock fans that came with the case were bland, anemic things that did little to showcase the powerful components within. Second, under a gaming load, the temperatures started climbing, and the noise from those cheap fans ramped up to an irritating whine. It was a high-performance engine in a lackluster chassis, and I knew I needed a change. The problem? A quick search for premium, RGB-lit, PWM-controlled fans revealed a staggering reality: a 3-pack from a top-tier brand could cost as much as a crucial component. This is the dilemma for so many builders: the frustrating choice between aesthetics, performance, and an exploding budget. Leaving your system with inadequate cooling isn’t an option—it can lead to thermal throttling, reduced component lifespan, and a noisy, unpleasant experience. This is precisely the gap the Thermalright TL-C12C-S X3 3-Pack 120mm ARGB PWM CPU Cooler Fan aims to fill.

What to Consider Before Buying Computer CPU Cooling Fans

A Computer CPU Cooling Fan, or more broadly, a case fan, is more than just an item to fill an empty slot in your chassis; it’s a key solution for thermal management, the lifeblood of a healthy, high-performing PC. These fans create a directed stream of air, establishing a critical cycle of drawing cool air in (intake) and expelling hot air out (exhaust). This process prevents heat from building up around sensitive components like your CPU, GPU, and motherboard VRMs. The main benefits are direct: lower operating temperatures, which in turn allow your components to boost to their maximum speeds for longer (improving performance), and a significant increase in the longevity of your hardware. A well-cooled system is a stable, quiet, and powerful system.

The ideal customer for this type of product is someone building a new PC on a sensible budget, or an existing PC owner looking to upgrade their system’s aesthetics and cooling without spending a fortune. If you’re tired of stock fans, want to add a vibrant splash of customizable color, and need better thermal performance for gaming or productivity, a value-oriented 3-pack is the perfect fit. However, this product might not be suitable for those building a completely silent workstation or a top-of-the-line, money-is-no-object showpiece. Users who demand the absolute lowest noise levels at every RPM or the most intricate, multi-layered RGB effects might consider alternatives from brands known specifically for those ultra-premium features, albeit at a much higher cost.

Before investing, consider these crucial points in detail:

  • Dimensions & Space: These are standard 120mm fans with a thickness of 25mm, the most common size for PC cases. Before buying any fan, you must confirm your case supports 120mm mounts in the locations you plan to install them. Also, consider the clearance if you’re mounting them on a thick radiator or a large CPU air cooler, ensuring they don’t interfere with tall RAM modules or motherboard heatsinks.
  • Capacity/Performance: Two numbers are key: Air Flow and Air Pressure. Air Flow, measured in CFM (Cubic Feet per Minute), tells you how much air the fan can move in open space, ideal for a case fan. Air Pressure, measured in mm H2O, indicates its ability to push air through resistance, like a dense heatsink or radiator. The Thermalright TL-C12C-S X3 3-Pack 120mm ARGB PWM CPU Cooler Fan offers a solid 66.17 CFM and 1.53 mm H2O, making it a versatile hybrid capable of performing well in either role.
  • Materials & Durability: The frame is made of polycarbonate, a standard for PC fans. While lightweight, some user feedback suggests it can be brittle around the screw holes if over-tightened. The most important durability feature, however, is the S-FDB (Fluid Dynamic Bearing). This is a high-end bearing type typically found in more expensive fans, promising quieter operation and a much longer lifespan than traditional sleeve or rifle bearings.
  • Ease of Use & Maintenance: Look for features that simplify installation. PWM (4-pin) control is essential for automatic speed adjustment based on temperature. For ARGB, daisy-chaining is a game-changer, allowing you to connect multiple fans to a single motherboard header, which is a massive win for clean cable management. For long-term care, fans will accumulate dust, which insulates heat; a simple cleaning with compressed air every few months is crucial for maintaining performance.

While the Thermalright TL-C12C-S X3 3-Pack 120mm ARGB PWM CPU Cooler Fan is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

Unboxing and First Impressions of the Thermalright TL-C12C-S X3

Upon receiving the Thermalright TL-C12C-S X3 3-Pack 120mm ARGB PWM CPU Cooler Fan, the packaging is straightforward and no-frills, which is exactly what we expect from a value-focused product. Inside, the three fans are securely nestled, along with a baggie containing 12 standard fan screws. The first thing we noticed upon picking up a fan was its weight. It’s constructed from polycarbonate and feels a bit lighter than some premium competitors, but not flimsy. The fan blades have a frosted, semi-translucent finish, which Thermalright calls “atomizing.” This design is specifically for diffusing the light from the hub-mounted ARGB LEDs, a thoughtful touch aimed at preventing the harsh, spotty look of cheaper RGB fans. Each fan sports two cables: a 4-pin PWM power connector and a 3-pin 5V ARGB connector. Crucially, both cables feature a daisy-chain passthrough, allowing you to link all three fans together. This is a standout feature at this price point, dramatically simplifying the build process. Overall, the initial impression is one of smart design choices focused on delivering the most sought-after features—ARGB and PWM control—in an accessible package.

In-Depth Performance Analysis: Putting the TL-C12C-S X3 to the Test

A spec sheet can only tell you so much. To truly understand a component’s worth, you have to integrate it into a system and push it. We installed the Thermalright TL-C12C-S X3 3-Pack 120mm ARGB PWM CPU Cooler Fan into our mid-tower test bench—two as front intakes and one as a rear exhaust—to evaluate every aspect of its performance, from raw cooling power to its acoustic signature and visual appeal.

Cooling Performance & Airflow Dynamics

The primary job of any fan is to move air, and on this front, the TL-C12C-S X3 delivers respectable numbers. With a maximum airflow of 66.17 CFM and a static pressure of 1.53 mm H2O, these fans are well-equipped for hybrid roles. In our testing, we configured them as case fans, replacing the stock units in a Lian Li Lancool 215. The immediate result was a noticeable drop in ambient case temperature, which translated to a 4-5°C reduction on our GPU and a 3-4°C drop on our CPU under a sustained gaming load in Cyberpunk 2077. This is a significant improvement that can prevent thermal throttling and allow components to maintain higher boost clocks for longer.

The PWM control is responsive and works flawlessly with our ASUS motherboard’s fan control software. We were able to set a custom fan curve that kept the fans spinning at a near-silent 700 RPM during idle and light desktop use. As temperatures climbed during gaming, the fans smoothly ramped up to around 1200 RPM, a sweet spot where they provided excellent airflow without becoming overly intrusive. This aligns perfectly with feedback from users who found they “keep my gaming PC cool during gaming session” and offer solid airflow. For anyone looking to replace inadequate stock fans, the thermal uplift provided by this 3-pack is immediately apparent and offers a tangible performance benefit, a fact you can see in its full feature set and user reviews. They move a serious amount of air when called upon, ensuring your expensive components get the cooling they need.

The Acoustic Experience: From Silent Whispers to a Noticeable Hum

Noise is the eternal enemy of the PC enthusiast. A product’s acoustic profile can make or break the user experience. Thermalright rates the TL-C12C-S X3 at 25.6 dBA, which is a quiet figure, but this is almost certainly measured at a mid-range speed, not full tilt. Our hands-on experience paints a more nuanced picture, one that largely confirms the consensus from user reviews. At idle and under 50% speed (below ~800 RPM), the S-FDB bearings do their job wonderfully. The fans are practically inaudible from a normal seating position, emitting just a faint whisper of moving air. They are, as one user put it, “pretty quiet” in this state.

However, as you push the fans towards their 1550 RPM maximum, the story changes. Above 1200 RPM, the fan noise becomes distinct, and at full speed, it’s a very audible hum. It’s not a high-pitched whine or a grating mechanical noise, but rather the sound of a large volume of air being moved quickly. This confirms reports from users who noted they are “a slightly louder than the standard fans” and “pretty loud at max rpm.” One user even measured an outlier fan at a very high decibel level, suggesting some variance in quality control. For us, the noise at 100% was too much for a quiet environment. The key, however, lies in the PWM control. By setting a smart fan curve that caps the speed around 70-80% (approx. 1100-1250 RPM), we found the perfect balance: effective cooling without excessive noise. Unless you are running intense stress tests, you will likely never need to run them at 100%, making the noise a manageable factor and a fair trade-off for the excellent price and cooling potential.

ARGB Illumination and Aesthetics

This is where the Thermalright TL-C12C-S X3 3-Pack 120mm ARGB PWM CPU Cooler Fan truly shines and punches far above its weight class. In the budget fan market, RGB can often be an afterthought—tacked-on, spotty, and with limited color vibrancy. That is not the case here. The “atomizing” fan blades are a brilliant design choice. The frosted texture catches the light from the hub-mounted LEDs and diffuses it evenly across the entire surface of the blade. The result is a soft, uniform, and deeply saturated glow that looks far more premium than its price suggests. There are no distracting “hotspots” or visible individual LEDs, just a smooth flow of color.

Connecting the 3-pin ARGB cable to our motherboard header was simple, and the fans were immediately recognized by ASUS Aura Sync software. We cycled through various effects—static colors, rainbow waves, breathing—and the fans responded perfectly. The colors are vibrant and accurate, making the inside of our case come alive. This experience is echoed by countless users who praise the aesthetics, saying, “They look great when just doing static RGB or even going with ARGB. The flow of colors is very satisfying.” While some hardcore RGB enthusiasts might note that the effects aren’t as complex as those on fans costing three times as much, for the vast majority of users, the lighting is more than sufficient; it’s a stunning visual upgrade. The ability to achieve such a clean, high-end look is a feature that really sets it apart in the budget category.

Installation and Cable Management: The Daisy-Chain Advantage

Building a clean PC is often a battle against cable clutter. The engineers at Thermalright clearly understood this, as the inclusion of daisy-chainable cables on the Thermalright TL-C12C-S X3 3-Pack 120mm ARGB PWM CPU Cooler Fan is a masterstroke of user-friendliness. Each fan has both a male and female connector for both the 4-pin PWM and 3-pin ARGB cables. This allows you to connect the first fan to the motherboard, the second fan to the first, and the third fan to the second. In the end, this entire array of three high-performance fans occupies only one PWM header and one ARGB header on your motherboard. This is a massive advantage, especially for builders using micro-ATX or mini-ITX motherboards where headers are in short supply.

The cables themselves are a generous 55cm long, providing enough slack to route them cleanly even in larger cases. While the daisy-chaining simplifies connectivity, some users have noted that you still end up with a fair amount of cable to manage. We found this to be true; the key is to plan your routing carefully, using zip ties to bundle the excess length behind the motherboard tray. Despite this minor management challenge, the benefit of using only two motherboard headers for three fans cannot be overstated. It simplifies the build, creates a cleaner final look, and makes these fans accessible even for novice builders who might be intimidated by complex wiring. It’s a thoughtful, practical design choice that makes the overall package incredibly compelling.

What Other Users Are Saying

Across the board, the sentiment surrounding the Thermalright TL-C12C-S X3 3-Pack 120mm ARGB PWM CPU Cooler Fan is overwhelmingly positive, centered on one key theme: incredible value. Users consistently refer to them as the “best bang for buck” and “insane value for the money.” One builder summed it up perfectly, comparing them to a single ARGB fan from a competitor and noting it would be “the same price for one… as three of these!” The praise isn’t just about price; many are genuinely impressed with the performance, stating the “airflow is solid” and the “RGB lighting is great.”

However, the feedback isn’t without its criticisms, which provide a realistic picture of the trade-offs. The most common complaint is noise, with several users pointing out that they are “a slightly louder than the standard fans” and can produce an “annoying buzz” at full speed. The other recurring issue is quality control. We saw multiple reports of a fan arriving with a cracked frame at a screw hole or, in one case, a damaged RGB cable. While most users received flawless units, these incidents suggest the polycarbonate material may be brittle and that handling during shipping or over-tightening screws during installation could pose a risk. This feedback is crucial: it frames the product not as a flawless giant-killer, but as a budget champion that delivers 90% of the performance and aesthetics of premium fans for a fraction of the cost, with some minor compromises.
