AI Verdict
This two-pack of 30mm fans is a quick, versatile cooling fix for basic Raspberry Pi projects, but don't expect Noctua-level longevity or silence under heavy loads.
These fans are an easy way to keep a stock Raspberry Pi from thermal throttling in a basic case. The split-pin design is great for choosing between 3.3V (quiet) and 5V (performance), but the sleeve-style bearings mean they aren't reliable for long-term 24/7 servers.
If you need 24/7 reliability and silence, upgrade to a 40mm 5V PWM fan with a MagLev or SSO bearing.

Chance this product isn't for you
Pros
- Includes two fans, eight screws, and eight nuts in the box
- Split 2-pin connector lets you easily swap between 3.3V and 5V GPIO pins
- Fits perfectly in standard Raspberry Pi and RetroFlag NESPI cases thanks to the 7mm thickness
- Drops idle Pi 4 temperatures by 10-15°C compared to passive cooling
Cons
- Hypro bearings often develop a scratching or rattling noise after a few months of 24/7 use
- Lacks PWM control, meaning it runs at a constant speed unless you build a custom script and circuit
- Airflow is relatively weak compared to thicker 10mm or 40mm fans
Dimension Scores
Moves enough air to prevent thermal throttling on a stock Pi 4, but struggles with heavy overclocking.
Quiet out of the box at 3.3V, but prone to developing bearing rattle over time.
The plastic housing is standard, but the Hypro bearings have a high failure rate for continuous 24/7 use.
The 2.6-inch wires are the perfect length for a standard Pi case without leaving a mess of slack.
Best For
- Retro gaming emulation consoles built inside a RetroFlag NESPI case
- Basic Pi-hole or Home Assistant servers running in a closet where minor fan noise doesn't matter
- Robotics projects needing active cooling on a 3.3V or 5V circuit
Not Recommended For
- Overclocked Raspberry Pi 4 or 5 setups running heavy sustained loads
- Silent bedroom media centers where bearing rattle will be noticeable
Watch Out For
- Bearing degradation — multiple users report the fans start making a scratching or whining noise after just a few weeks of continuous operation.
- No software speed control — the 2-pin design means it runs at 100% speed constantly unless you manually unplug it or wire it to a separate transistor.
- Flimsy wire connections — the 2.6-inch cables are thin and can easily snap at the solder joint if you pull them too hard during installation.

What Buyers Say
Getting two fans and all the mounting hardware in one package solves the immediate need for basic cooling. The split 2-pin connector is a massive hit because it lets you easily toggle between 3.3V for silence and 5V for maximum cooling. The Hypro bearings are a frequent source of complaints, with many users noting a scratching or whining noise developing after a few months of continuous use. Most view this as a quick-fix cooling solution rather than a long-term component.
“Fits my retro case perfectly and cools well, but one of them started making a horrible grinding noise after just a month of being left on.”
Common Praise
- Split connector makes swapping between 3.3V and 5V incredibly easy
- 7mm thickness fits perfectly in tight enclosures like the NESPI case
- Drops idle temperatures by 10-15°C immediately upon installation
- Includes all necessary screws and nuts, saving a trip to the hardware store
Common Complaints
- Bearings start rattling or scratching after a few weeks of 24/7 operation
- Wires are very thin and fragile near the fan hub
- Loud and whiny when running at the full 5000 RPM 5V speed
- No PWM control for automatic temperature-based fan curves
Ownership Tips
- Running them at 3.3V significantly extends the lifespan of the bearings compared to 5V.
- Dust buildup happens fast — you'll need to blow them out monthly if your case lacks a filter.
- The screws can strip the plastic housing if you overtighten them during installation.
Frequently Asked Questions
How do I change the fan speed?
You have to manually move the positive wire on your Pi's GPIO header. Plug it into pin 1 (3.3V) for low speed, or pin 2 or 4 (5V) for high speed.
Will this fit the official Raspberry Pi 4 case?
No, the official case doesn't have standard 30mm mounting holes. You'll need a third-party case or a 3D-printed lid that supports 30x30mm fans.
Does it come with mounting hardware?
Yes, the two-pack includes 8 screws and 8 nuts, which is exactly enough to mount both fans.
Can I control this fan with software?
Not out of the box. It's a 2-pin fan, so it lacks the PWM wire needed for software control unless you wire it through a separate transistor circuit.
How loud is it at 5V?
The spec sheet claims 15.92dBA, but users report a noticeable hum at 5000 RPM on 5V. Moving it to the 3.3V pin makes it nearly silent.
Buying Guide
When buying a fan for a Raspberry Pi, you have to decide between basic active cooling and long-term reliability. These 30mm fans are standard issue for most third-party cases, but they use sleeve-style bearings that degrade when running 24/7. If you just need to keep a retro gaming console cool during weekend play sessions, these are perfect. If you're building a home server that will run non-stop for years, you'll want to look elsewhere.
3007 Size (30x30x7mm)
This is the physical footprint. Think of it like a standard tire size for Pi cases — 30mm is the width, and 7mm is the thickness, ensuring it won't hit the GPIO pins when the case is closed.
2-Pin Split Connector
Instead of a single block, the positive and negative wires have their own plugs. This lets you plug the red wire into either the 3.3V or 5V power pins on the Pi, acting like a manual speed switch.
Hypro Bearing
This is a sealed sleeve bearing. It's simple to manufacture and quiet at first, but the lubricant dries out faster than a ball bearing, leading to noise over time.
Alternatives
If you need silent, 24/7 reliability, search for a '40mm 5V PWM fan with a MagLev or SSO bearing' to get software speed control and a much longer lifespan.
