Does the Geekworm P173 fit a Raspberry Pi 5?
No. Geekworm lists the P173 as compatible with the Raspberry Pi 4 Model B only, in 1GB, 2GB, 4GB, and 8GB versions.

It measures 90 x 65 x 33 mm (3.54 x 2.56 x 1.30 in) and the heavy-duty heatsink shell weighs up to 174 grams net.
Is a fan needed with this case?
No. The P173 is a passive design with four built-in heatsink pillars, so no extra fan is required.
