Pros & Cons
Pros
- ✓ CNC aluminum body acts as one large passive heatsink for the Pi 4
- ✓ 5mm spin heat sink on the base adds cooling surface area
- ✓ Only 16mm thick, slim enough for cabinets and behind-TV mounts
- ✓ Acrylic window keeps WiFi and Bluetooth signal loss minimal
- ✓ Fits all Pi 4 Model B versions (1/2/4/8GB) with full port access
Cons
- ✗ Passive only, with no fan option for sustained heavy loads
- ✗ Aluminum shell gets warm to the touch as it draws heat off the board
- ✗ 16mm profile leaves no internal room for stacked HAT boards
- ✗ Cooling depends on seating the included thermal pad correctly
Manufacturer description
The Geekworm N300 is a CNC-machined aluminum alloy case built for the Raspberry Pi 4 Model B in all four memory versions: 1GB, 2GB, 4GB and 8GB. The whole enclosure works as a passive heatsink, so your Pi stays silent. There is no fan to whine, collect dust or take up a power pin. Cooling comes from a 5mm-thick spin heat sink machined into the bottom of the case. A thermal pad is included to carry heat from the board into the aluminum, which helps protect your Pi 4 from overheating during long emulation sessions, media playback or always-on server work. The N300 is only 16mm thick, so it…
SpecPicks Verdict
SpecPicks scored Geekworm N300 Ultra-Thin Aluminum Alloy Heatsink Case using a rating × review-volume × price-fit model applied to published specs and reviews across the emulation hardware category. Geekworm's emulation hardware lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for emulation hardware of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
Will the Geekworm N300 fit my Raspberry Pi 5?
No. The N300 is made for the Raspberry Pi 4 Model B. For a Raspberry Pi 5, Geekworm points buyers to its N310 or N311 models.
Does it work with the 8GB Raspberry Pi 4?
Yes. The N300 fits every Raspberry Pi 4 Model B memory version: 1GB, 2GB, 4GB and 8GB.
How does a fanless case keep the Pi 4 cool?
The CNC aluminum alloy body works as a heatsink. The included thermal pad carries heat from the board into the case, and a 5mm-thick spin heat sink on the bottom adds surface area to shed it.
Will a metal case kill my WiFi or Bluetooth signal?
Geekworm puts a black translucent acrylic plate over the case to keep WiFi and Bluetooth working, and describes signal loss as almost none.
Can I still reach all the ports with the case on?
Yes. The N300 gives access to all ports on the Raspberry Pi 4 Model B, and the whole case is only 16mm thick.
