Small-form-factor builds turn every fan choice into a clearance and comfort decision. In a compact ITX case, a 92mm fan may be the only practical rear exhaust, side intake, or CPU-adjacent airflow option—and the wrong frame depth can interfere with a cooler, GPU, cable run, or panel. PWM control matters here because it lets the fan slow down when the system is idling instead of running at full speed all day.
This list focuses on the best 92mm PWM fans for ITX cases where buyers need to balance cost, thickness, appearance, and basic mounting compatibility. The standout options include standard 25mm-thick models for conventional placements and 15mm slim fans for particularly tight layouts.

How We Compared
For an ITX-focused 92mm roundup, fit comes first. We prioritized products specifically described as 92mm PWM or 4-pin PWM fans, then separated slim 15mm options from standard 25mm models because that difference can determine whether a fan fits at all. We also considered practical buyer needs: included cable-splitting capability, stated 0dB operation, available color variants, ARGB lighting, and listed speeds where provided.
Price was another major factor. Performance claims, acoustic results, airflow figures, electrical draw, and weight are not added where they were not provided. Before ordering, confirm your case’s fan clearance, mounting pattern, header availability, and whether nearby components leave enough room for a 25mm or 15mm frame.
The 7 Best Picks
1. ARCTIC P9 PWM PST
The ARCTIC P9 PWM PST is the practical pick for an ITX owner who wants a basic 92mm PWM case fan without spending much. Its listed 0dB mode is also appealing for builders who want a fan that can stop under appropriate low-demand conditions. This is a straightforward airflow-focused choice rather than a lighting-centered upgrade.
- Pro: Includes a cable splitter for easier fan connection planning.
- Pro: Listed 0dB mode supports low-activity operation goals.
- Con: It is not positioned as an ARGB or color-theme fan.
Skip it if your build needs a 15mm slim fan or visible lighting.
2. Thermalright TL-9015
The Thermalright TL-9015 is made for the clearance-sensitive side of ITX building. Its 15mm ultra-thin design is the key feature: compared with a standard 25mm frame, it gives back 10mm of space where a panel, cooler, radiator, cables, or graphics card leaves little room. It uses a 4-pin PWM connection and carries a stated maximum speed of 2700RPM.
- Pro: The 15mm ultra-thin frame suits constrained installations.
- Pro: 4-pin PWM control and a stated 2700RPM speed.
- Con: It costs more than several standard-depth options here.
Skip it if your case has room for a 25mm fan and you do not need the extra clearance.
3. Noctua NF-A9x14 PWM
The Noctua NF-A9x14 PWM is the premium slim choice for builders who have already confirmed that a 15mm-class 92mm fan is necessary. It is described as a high-performance quiet 92mm fan and uses PWM control, making it a natural fit for compact systems where fan behavior should adapt to system demand.
- Pro: High-performance quiet positioning for compact builds.
- Pro: PWM control in a slim 92mm format.
Skip it if you simply need an inexpensive standard 92mm PWM case fan.
4. Thermalright TL-P9
The Thermalright TL-P9 is the value-first standard-depth selection. Listed as a 92mm-by-25mm, 4-pin PWM computer fan, it is intended for buyers with ordinary 25mm fan clearance who want a low-cost cooling addition. This is the sensible no-frills choice when the case does not demand a slim frame or a lighting feature.
- Pro: Standard 25mm depth works for conventional 92mm mounts.
- Con: A 25mm frame will not solve slim-clearance problems.
Skip it if your side panel or nearby hardware leaves only 15mm of fan depth.
5. Thermalright TL-9015B
The Thermalright TL-9015B brings the slim 15mm format to builders who want a black fan for a darker ITX interior. It has a 4-pin PWM connection and a stated 2700RPM speed, matching the basic slim-build mission of the other TL-9015 option while offering a black finish designation. It is best considered when visual consistency matters alongside clearance.
- Pro: Black color option for coordinated internal builds.
- Pro: 15mm slimline design with 4-pin PWM and 2700RPM stated speed.
- Con: It costs more than the white TL-9015W.
Skip it if your case is white-themed or if a standard 25mm fan fits comfortably.
6. Thermalright TL-9015W
The Thermalright TL-9015W is the slim fan to consider for a white ITX build that cannot accommodate a 25mm frame. It uses a 15mm slimline design, a 4-pin PWM connection, and a stated 2700RPM speed. The listing also states low noise at 22.4dBA, which will interest buyers building a visually clean, compact desktop near a workspace.
- Pro: 15mm slimline design frees space in constrained cases.
- Pro: White finish, PWM control, and a listed 22.4dBA noise figure.
- Con: White styling may stand out in an all-black build.
Skip it if color does not matter and you need a conventional 25mm fan instead.
7. THERMALRLGHT TL-P9-S
The THERMALRLGHT TL-P9-S is the visual-upgrade option for ITX builders who have a standard-depth 92mm mount and want ARGB lighting. It is a 92mm ARGB PWM fan with a stated 2200RPM speed and listed dimensions of 3.62 inches long by 92mm wide by 25mm high. Its 25mm height still needs to be checked carefully in tight cases.
- Pro: ARGB lighting adds visual interest to a small build.
- Pro: PWM operation and a stated 2200RPM speed.
- Con: Its 25mm height is less suitable for slim-only locations.
Skip it if your case needs a 15mm fan or you prefer an unlit interior.
Buying Guide
Measure Depth Before Comparing Features
The most important distinction in this group is 15mm versus 25mm depth. A 92mm fan can have the correct width and still fail to fit because its frame is too deep. Choose a 15mm model—the TL-9015, TL-9015B, TL-9015W, or NF-A9x14 PWM—when clearance is genuinely limited. Choose a 25mm model, such as the TL-P9 or TL-P9-S, when your case supports standard fan depth. Measure from the mounting surface to the nearest obstruction, including a side panel, heatsink edge, cable bundle, or GPU backplate.
Choose PWM for Better Everyday Control
Each pick here is described as PWM or 4-pin PWM, which is useful for ITX systems that can quickly become louder when heat accumulates. PWM allows the motherboard or compatible controller to adjust fan behavior based on temperature settings. Confirm that you have an available 4-pin fan header, or plan the connection layout before buying. The ARCTIC P9 PWM PST is especially worth considering when fan-header planning is the problem because it includes a cable splitter.
Match the Fan to the Build’s Visual Priorities
In an ITX case, a fan may be highly visible through a mesh panel or window—or completely hidden. If it is visible, the black TL-9015B, white TL-9015W, and ARGB-equipped TL-P9-S give you clearer styling directions. If it is hidden behind a panel, the ARCTIC P9 PWM PST or Thermalright TL-P9 may be the more economical choice. Do not pay for lighting if the location cannot show it, and do not select a color variant before verifying that its depth fits.
Our Verdict
Choose the Noctua NF-A9x14 PWM when you specifically want a premium-priced slim fan with high-performance quiet positioning. For an illuminated build with space for 25mm depth, choose the TL-P9-S.
FAQ
Will a 92mm fan fit every ITX case?
No. ITX describes motherboard size, not case fan support. Check whether your case has a 92mm mounting location, then verify frame depth clearance. A 25mm fan may not fit where a 15mm slim fan does.
What is the difference between a 15mm and 25mm 92mm fan?
Both can be 92mm wide, but the 15mm model is 10mm thinner than a 25mm model. That extra space can matter around side panels, CPU coolers, graphics cards, and cable routes in compact systems.
Which option is best for a white ITX build?
The Thermalright TL-9015W is the direct white slimline option.
Do I need ARGB on a 92mm ITX fan?
No. ARGB is a visual feature, not a fit requirement. The THERMALRLGHT TL-P9-S is the relevant choice if your fan mount is visible and supports a 25mm-high frame. For hidden mounts, a non-ARGB option may be the better value.
