It has an internal fan hookup, but isn't used by Apple. The Cube is also a popular candidate for MacQuariums. After one year of production, Apple put the Cube "On Ice." Thanks to its passive cooling, the Cube was virtually silent-except for the original 5400 RPM hard drive. While this clock rate is significantly lower than the competing intel chipsets of the time (1.3 Ghz Pentium 4 at the high end), the Cube's G4 featured an AltiVec module and a more efficient architecture (RISC vs CISC), making the PowerPC chip faster than an Intel CPU running at the same clock speed. The Cube boasted a 450MHz or 500Mhz G4 CPU, wich was faster than entry-level PowerMac G4s of the same year. However, overheated CPUs are a rare problem with stock hardware, a fan is a necessary addition with any third party CPU-upgrades. This was seen as a mistake on Apple's part, because G4 processors run very hot.

Unlike most other computers, the Cube used passive cooling, with no fans. Released in 2000 at a cost of $1599, the cube was considered too expensive compared to full-size PowerMac G4s. The infamous Powermac G4 Cube, Apple's original failed attempt at a compact G4-based Macintosh.
