Other PCs will glow with envy if you snag these discounted RGB fans for $42

If you're building a gaming PC, one of the most important things you need to do is to keep it cool. While you're keeping its temperature cool, you might as well make sure that it looks cool as well. The Thermaltake Pure 12 ARGB fan has nine addressable LEDs that can create 16.8 million colors. A three-pack of these fans is only $42 right now.

The Thermaltake Pure 12 ARGB fans can sync with US aura Sync, Gigabyte RGB FUSION, MSI Mystic Light Sync, and ASROCK polychrome. This makes it easy to keep the color of your fans in sync with your gameplay. You can also control the color of the fans manually with an analog ARGB controller.

The fans support motherboards that have a 5V addressable RGB header. Pure ARGB fans are available in 12 cm, 14 cm, and 20 cm models, though Amazon's sale is only for the 12 cm (120 mm) fans.

As for the fans themselves, they're designed to reduce noise. They have hydraulic bearings that self lubricate to reduce friction and to keep things quiet.

If you're going all-in on RGB for your PC build, you can pair the Thermaltake Pure ARGB fans with one of the best Thermaltake PC cases and the best DDR4 RAM for your PC. Many of Thermaltake's PC parts have (or allow for) enough lighting to make holiday lights green with envy.
