12 min read5 products evaluated
Around $25 case fans add PWM speed control and addressable lighting on three-packs. Every pick cost 20 to 25 when we checked and lists its size and speed.
This is a research roundup, not a lab test: fans in box, max speed and rated noise come from each maker's published specs; nothing here was tested in-house, and a missing max speed is flagged, not filled in.

Our Picks
Largest Pack Size1 of 5
Thermalright TL-C12C-S (5 Pack) on Amazon (opens in a new tab)
Thermalright's TL-C12C-S five-pack offers 66.17 CFM at 1550 RPM with ARGB lighting.
Best for
- Buyers who put pack size first.
Skip if
- Look at the other picks if you need a feature not covered above.
Why we like it
At the time of writing it cost less per fan than any other pick here. Its 5 fans pack size is the largest here; the Silent Wings 4 comes next at 1 fan. A 25.6 dBA rated noise is unique to it among these picks, while the Silent Wings 4 140mm uses a 29.3 dB(A) rated noise.
It also comes with 55cm cables for daisy-chained PWM control. Check that your case has 120mm mounts in the positions you plan to use, and how many fan headers your motherboard offers. With 5 fans, use a splitter or hub rather than several headers, and check the header's current rating; each fan's draw is on the label.
ARGB lighting needs a 5V 3-pin ARGB header or the included controller; do not connect it to a 12V RGB header. No other pick here cost less at our last price check, and the Silent Wings 4 was closest.

What to Look for in a Case Fan Under $25
Key buying criteria so you get the right fit the first time.
Pack size across these picks
Across these 5 picks pack size spans 1 fan (the NF-A14 PWM) to 5 fans (the TL-C12C-S 5-pack). If pack size is your first filter, the TL-C12C-S 5-pack sets the ceiling at 5 fans.
Top speed
Here top speed runs from 1500 RPM on the NF-A14 PWM to 1550 RPM on the TL-C12C-S 5-pack, a 3% spread. Start with the TL-C12C-S 5-pack if top speed decides it. The Silent Wings 4, the Silent Wings 4 120mm and the Silent Wings 4 140mm give no top speed figure, so 2 of 5 picks are compared here.
Bearing
The TL-C12C-S 5-pack lists S-FDB; the Silent Wings 4 lists Fluid-dynamic; the Silent Wings 4 120mm and the Silent Wings 4 140mm list Fluid dynamic. Settling bearing first narrows 4 picks to 2 or 1 or 1.
Features beyond the spec table
The Silent Wings 4: a funnel-shaped frame outlet for higher air pressure. The Silent Wings 4 120mm: a six-pole motor with three phases. The NF-A14 PWM: Flow Acceleration Channels.
Budget
Price does little to separate these 5: the TL-C12C-S 5-pack through the NF-A14 PWM all landed in the under $50 tier, which leaves pack size to decide it.
