Verdict: The Endorfy Fortis 5 Dual Fan is an excellent value air cooler when quiet gaming, broad socket support and memory clearance matter more than maximum sustained cooling. Its six-heat-pipe single tower stays impressively quiet and handles mainstream Ryzen 5/Ryzen 7, Core i5 and power-limited Core i7 systems well. It is a less convincing choice for unrestricted Core i7/i9 rendering, manual overclocking or any build where a larger dual-tower cooler costs only slightly more.
What the Fortis 5 Dual Fan is
The Fortis 5 Dual Fan is a conventional single-tower heatsink with six copper heat pipes, an aluminum fin stack and two front-to-back fans: a 140 mm Fluctus 140 and a 120 mm Fluctus L120. The heatsink is offset asymmetrically to improve DIMM clearance. It has no RGB or ARGB lighting, uses PWM control and FDB bearings, and includes Endorfy’s Pactum PT-3 thermal compound. Endorfy rates it at 220 W, but that is a manufacturer positioning figure rather than a standardized guarantee for every CPU and workload. See the current specifications at Endorfy.

The second fan improves airflow through the stack, but this remains a single tower. It does not have the heat-transfer area of a large dual-tower cooler, so do not treat “dual fan” as equivalent to “dual tower.”

#1 Best Overall
- Quiet Fan - The ENDORFY Fluctus 140 PWM fan with a fan stop mode ensures constant airflow. Its serrated fan blades are designed to push as much air as possible through the tightly arranged heatsink fins while lowering noise levels (the psychoacoustic optimization of Fluctus fans is patent pending).
- Black finish - To achieve minimalism, each element of the cooler is kept in a dark colour. This makes the ENDORFY Fortis 5 Black look good in classic setups as well as between backlit components.
- The most powerful CPU cooling – The heatsink with densely arranged cooling fins and six direct-touch heatpipes ensures premium CPU cooling. The ENDORFY Fortis 5 Black is optimised for unidirectional airflow for the best possible performance.
- Quick installation - The newly developed mounting system is easy to use, even if you are not an experienced user. ENDORFY Fortis 5 Black is compatible with all modern AMD and Intel sockets on the market.
- Pactum PT-3 Thermal Paste - Together with the cooler, you will receive a tube of the easy to apply and efficient Pactum PT-3 thermal paste. The tube is more than sufficient to guarantee multiple correct applications.
The critical case measurement is the 159 mm cooler height. Compare it with the case maker’s CPU-cooler limit and leave practical tolerance for side-panel bulges, filters and manufacturing variation. The offset fin stack clears most memory modules on typical ATX boards, although unusually tall DIMMs can still meet the front fan depending on its vertical position.
Installation: straightforward, with two fiddly details
- Confirm the socket, case height and supplied mounting hardware.
- Install the socket backplate, standoffs and brackets specified for your platform.
- Check airflow direction and cooler orientation before tightening; the mounting plate limits rotation after installation. PC Gamer found that only a 180-degree reorientation was available once the plate was fitted.
- Apply the included Pactum PT-3 paste.
- Set the heatsink on the CPU and tighten its two mounting screws evenly.
- Attach the 140 mm and 120 mm fans with the supplied clips, then connect their 4-pin PWM leads.
The clips work, but attaching or removing them is more awkward than a screw-mounted fan system. Use Endorfy’s safety manual for platform-specific diagrams.
Noise: its strongest advantage
Independent figures vary because the outlets used different benches, rooms, instruments and test methods. AnandTech measured 37.7 dBA at 1,400 RPM and 32 dBA at roughly 700 RPM. PC Gamer measured 42 dBA at full speed and reported no prominent whine or high-pitched character, with mid-to-low speeds effectively inaudible inside a typical case.
| Source and condition | Reported result |
|---|---|
| AnandTech, maximum speed | 1,400 RPM; 37.7 dBA |
| AnandTech, approximately half speed | About 700 RPM; 32 dBA |
| PC Gamer, full speed | 42 dBA |
Endorfy advertises fan-stop operation. Whether the fans actually stop depends on the motherboard’s PWM mode, minimum duty-cycle threshold, temperature hysteresis and BIOS profile. Confirm that both fans are detected and create a gradual temperature-based curve rather than assuming zero RPM will work automatically.

Thermal performance in real workloads
Independent thermal baseline
AnandTech measured 0.1277°C/W average thermal resistance at maximum speed (37.7 dBA) and 0.1781°C/W at about half speed (32 dBA). The cooler performed well for its cost and acoustics, while larger dual-tower designs pulled ahead as heat loads increased because they expose more fin area.
Gaming and mixed desktop use
In PC Gamer’s testing with an Intel Core i7-14700K, the Fortis reached a 79°C peak in Metro Exodus Enhanced Edition. That result reflects a gaming workload, not a universal temperature promise. For gaming, compiling, office work and mixed use, the cooler’s noise and memory clearance are more meaningful advantages than its maximum heat capacity.
Rank #4
- ARGB Lighting Sync: The RGB of cooler can sync with motherboard via 5V 3-Pin port, customize lights your builds and components
- PWM Smart Control: 4-Pin PWM cable allows for dynamic speed adjustment between 800-1700 RPM, min noise or max airflow
- Better Thermal Conductivity: Five direct access heat pipes, high-density aluminium fins and larger copper base provide the great thermal conductivity and maintain cooling operation
- Low Noise Operation: Nine fan blades and eight vibration rubber pads provide the better silent experience and great airflow for the case and components
- AMD/Intel Bracket Support: Intel LGA 1851/1700/1200/1150 & AMD AM5/AM4 supported
Long all-core workloads
The same review recorded approximately 95°C in a 10-minute Cinebench stress test and about 99°C during x264 encoding, at roughly 42 dBA, without throttling in the reported setup. Those results show why an unrestricted high-power Intel processor is a different proposition from a gaming system. Ambient temperature, case airflow, mounting, motherboard power limits and fan curves can materially change the outcome.
Modern CPUs often boost until they encounter a thermal or power limit. A high stress-test temperature does not by itself indicate a defective cooler, but sustained rendering, Blender, HandBrake, x264 or manual overclocking leaves less margin than a larger dual tower or 240/360 mm liquid cooler.
Best Value
- Premium fan: award-winning ENDORFY Fluctus 140 PWM ARGB fan with fan stop function guarantees low temperature in demanding conditions. The profiled rake edges of the blade accurately flight the densely arranged fins of the heat sink while reducing the noticeable audibility of the working Fortis (psychoacoustic optimization of fans is pending patent).
- Black finish – with fans of timeless minimalism in mind, every element of the cooler is in deep black. This makes the ENDORFY Fortis 5 Black ARGB look good in both classic cases and in the surroundings of illuminated components.
- ARGB – you can illuminate the cooler in any colour or set the illumination effect – for example a shimmering rainbow or pulsating wave. With the included Nano-Reset ARGB controller, you don't need a compatible motherboard or case with the right driver for this
- Cooling at the highest level: the densely ribbed heat sink embedded on the base with six heat conductors is great for collecting heat energy from the processor. Combined with the optimization for one-way airflow of the ENDORFY Fortis 5 Black ARGB ensures the highest cooling level.
- Easy and safe installation: the included frame makes it easy to install the cooler even less experienced users who have never had to install components. ENDORFY Fortis 5 Black ARGB is suitable for use with AMD and Intel platforms.
What the 220 W label does—and does not—mean
Endorfy’s 220 W figure is useful for positioning, not a cross-brand measurement standard. CPU package power, workload duration, firmware power limits, ambient temperature, case ventilation and mounting quality determine actual temperatures. A power-limited Core i7 may be a sensible match; an unrestricted Core i9 running hours of all-core work is not the same test.
Comparisons that matter
Fortis 5 versus Fortis 5 Dual Fan
| Model | Fans | Listed dimensions | Official Polish price signal (August 2026 crawl) |
|---|---|---|---|
| Fortis 5 | 1 × 140 mm | 159 × 144 × 107 mm | 189 zł |
| Fortis 5 Dual Fan | 140 mm + 120 mm | 159 × 144 × 131 mm | 229 zł |
The standard Fortis 5 is 24 mm shallower and may suit a tighter case or moderate-power CPU. The Dual Fan version adds airflow potential and more acoustic headroom. These are Polish storefront signals, not guaranteed US or other-region street prices.
Larger dual-tower air coolers
Noctua NH-D15-class coolers provide more fin area and greater sustained thermal headroom. PC Gamer reported the NH-D15 G2 running about 10°C cooler than the Fortis in its Metro Exodus test, but at considerably higher cost. AnandTech likewise found larger towers ahead under heavy loads. They are the better choice when temperature margin matters more than compact memory-friendly design.

PC Gamer reported Arctic’s Liquid Freezer III 360 A-RGB reducing Cinebench temperatures by nearly 20°C versus the Fortis in its test, while costing roughly three times as much or more. AIO cooling can improve sustained thermals, but adds pump noise, radiator-space requirements, installation complexity and another component that can fail.
Who should buy it?
- Gamers seeking quiet air cooling near the $50 class.
- Owners of Ryzen 5/Ryzen 7, Core i5 or power-limited Core i7 systems.
- Builders with tall RAM who want an offset, relatively clearance-friendly tower.
- Users who prefer air cooling’s simplicity over an AIO pump.
- Anyone valuing a six-year warranty and included thermal paste.
Who should skip it?
- Users running unrestricted Core i7/i9 processors under long all-core loads.
- Manual overclockers or buyers seeking the highest possible air-cooling performance.
- Small-form-factor builders with less than 159 mm of cooler clearance.
- RGB-focused builds; this model has no lighting.
- Shoppers who can buy a substantially stronger dual-tower cooler for only a little more.
Buying checklist
- Match your exact CPU socket to the current Endorfy listing and package hardware.
- Confirm at least 159 mm of case clearance with the side panel closed.
- Check RAM height and the front fan’s final position.
- Consider CPU power limits, not only the processor’s model name.
- Compare the live local price with dual-tower alternatives.
- Decide whether you need RGB or fan-stop behavior.
- Set the motherboard header to 4-pin PWM and tune a gradual fan curve after installation.
Final recommendation
At about $50 or the equivalent local price, the Fortis 5 Dual Fan is a compelling quiet-gaming and mixed-use cooler: well equipped, broadly compatible, memory-conscious and backed by a long warranty. Its single-tower design is the boundary to remember. If your priority is hours of unrestricted rendering, heavy encoding or overclocking a high-power Intel CPU, spend more on a larger dual tower or a suitable AIO instead.
