AI Verdict
It’s a cheap, all-in-one cooling kit that keeps your Pi 3B+ from thermal throttling, but you'll need patience to peel and stack the nine layers of acrylic.
If you just need a cheap, all-inclusive starter kit for a Pi 3B+, this hits every mark by bundling the power supply, heatsinks, and fan. The tedious 9-layer assembly and tight cable clearances make it a headache if you plan to swap boards or use heavy-duty cables.
If you hate assembling puzzle-piece cases, look for a snap-together aluminum case that uses the whole body as a passive heatsink.

Pros
- Includes a 5V 3A power supply with an inline ON/OFF switch so you don't have to yank the cord.
- Dual cooling setup with a 30mm fan and 3 aluminum heatsinks prevents thermal throttling under heavy CPU loads.
- Fan runs at 3.3V for silence or 5V for maximum cooling just by swapping GPIO pins.
- Clear 9-layer acrylic design leaves the GPIO and camera ribbon slots fully accessible.
Cons
- Assembly requires peeling protective paper film off both sides of all nine acrylic layers.
- Plastic cutouts around the HDMI and micro-USB ports block cables with thick rubber boots.
- The 30mm sleeve-bearing fan develops a whine or rattle after a few months of 24/7 use.
- Zero vertical clearance for a PoE HAT or bulky top-mounted expansion boards.
Dimension Scores
The 5V 3A power supply easily handles the Pi 3B+ without under-voltage warnings.
The 30mm fan is quiet at 3.3V but gets whiny at 5V, and the cheap bearings often rattle over time.
The stacked acrylic feels solid, but the tight port cutouts show a lack of design foresight.
No internal routing exists, and the tight exterior cutouts actively fight against thicker HDMI cables.
Best For
- RetroPie gaming setups where the CPU gets pushed hard enough to need active cooling.
- Always-on Pi-hole or Home Assistant servers tucked away on a shelf.
- Beginners who want a complete case, cooling, and power supply bundle for under $20.
Not Recommended For
- Raspberry Pi 4 or 5 owners — the port layout is completely different.
- Projects requiring a PoE HAT or large GPIO-mounted displays.
Watch Out For
- The HDMI and power cutouts are notoriously narrow; if your cables have thick plastic housings, you might literally have to snap off a piece of the acrylic to make them fit.
- You have to assemble the case layer by layer around the Pi. If you mess up the order, you have to unscrew the whole thing and start over.
- The included micro-USB cable is wired for power only, so don't try to use it for data transfer on other devices.

What Buyers Say
Buyers buy this kit for the sheer value of getting a case, fan, heatsinks, and a 3A power supply with an inline switch. The cooling performance drops load temps by 15-20°C compared to a bare board. The assembly process is a notorious pain point. Users constantly complain about having to peel the stubborn brown paper off 18 individual sides of acrylic before stacking them like a sandwich. Several owners also noted that the plastic around the HDMI port is too thick, forcing them to shave down their cables or snap the case.
“Great value for the power supply and cooling, but peeling the paper off the 9 layers of plastic made me want to throw it out the window, and I had to break a piece off just to plug in my HDMI cable.”
Common Praise
- The inline power switch completely eliminates the need to yank the micro-USB cord to reboot.
- Drops CPU temperatures by up to 20°C under heavy RetroPie emulation loads.
- The 3A power supply prevents the low-voltage warnings common with standard phone chargers.
- Layered acrylic design feels surprisingly heavy and durable once fully screwed together.
Common Complaints
- Peeling the protective paper off all 9 layers takes longer than setting up the Pi.
- The HDMI and power cutouts are too narrow for cables with thick rubber boots.
- The tiny 30mm fan starts to rattle or whine after a few months of continuous use.
- Taking the SD card out requires tweezers because the acrylic layers make the slot too deep.
Ownership Tips
- The fan will inevitably start buzzing after 3-6 months; running it on the 3.3V pin delays the wear.
- If you need to swap the SD card frequently, you'll want to leave the bottom layer slightly loose or use a pair of tweezers.
- Dust builds up quickly between the acrylic layers and is impossible to clean without fully disassembling the case.
Frequently Asked Questions
Does this fit the Raspberry Pi 4?
No. The port layout on the Pi 4 is completely different with dual micro-HDMI and USB-C. This only fits the Pi 3B+, 3B, and 2B.
How do I change the fan speed?
You can't change it via software. You swap the fan's red wire between the 5V GPIO pin for full speed and the 3.3V pin for a quieter, slower speed.
Does the power supply actually output 3 Amps?
Yes, the included 5V 3A adapter provides plenty of headroom to prevent the under-voltage lightning bolt icon, even with USB peripherals attached.
Can I use a PoE HAT with this case?
No. The layered acrylic design sits flush against the board and leaves absolutely zero vertical clearance for a Power over Ethernet HAT.
Why are the acrylic pieces brown and opaque?
Every single piece of acrylic is covered in a brown protective paper film to prevent scratches during shipping. You have to peel it all off before assembly.
Buying Guide
When buying a case for an older Raspberry Pi 3B+, your main enemies are heat and power delivery. The Pi 3B+ runs notoriously hot under load, so you absolutely need active cooling or a massive passive heatsink if you're doing anything beyond basic tasks. You also need a dedicated power supply since relying on an old phone charger will cause under-voltage crashes. A kit like this solves both problems at once, but be prepared for a tedious, puzzle-like assembly process.
5V 3A Power Supply
The Pi 3B+ requires at least 2.5 Amps to run stably. A 3A supply gives you extra headroom to power USB devices like keyboards or hard drives without crashing the system.
Inline ON/OFF Switch
The Raspberry Pi doesn't have a power button. Without this switch, you have to physically unplug the micro-USB cable from the board to turn it off, which wears out the port over time.
30mm Cooling Fan
It acts like a tiny exhaust system. Without it, the Pi's CPU will hit 85°C and automatically slow itself down to prevent damage.
Alternatives
If you want silent cooling without moving parts, look for an aluminum flirc case that acts as a giant passive heatsink. If you need to use expansion boards, look for an open-air case with standoffs.
