About the Raijintek LETO PRO RGB CPU cooler…

This is the Raijintek LETO Pro RGB tower-type CPU cooler, which is bundled with 2x 120mm sleeve bearing fan which has RGB led rings around it. Practically everybody jumped inside the RGB rabbit hole (resistance is futile) but it is nice to see Raijintek providing the white LED version of the cooler as well.

Single-tower CPU coolers are still very popular because of its form factor. Such tower coolers do not have any clearance issues with many standard ATX cases. The LETO Pro’s heatsink width is 51 mm, and with a pair of is 120 x 120 x 25 mm fans its a total of 101 mm. Because of its slim design, it will stay between VRM heatsink and the DIMM slot. While its nothing new, many of such CPU coolers tend to provide great performance for the price that ends up as best sellers. Coolermaster Hyper 212X is a great example. Noctua NH-U12SE2 is also on the similar lines. To add Raijintek’s credit, the CPU cooler has a matte black finish giving a stealth look to the CPU cooler.  This is the first Raijintek product I am reviewing so it will be interesting to see how it goes…


There’s the LETO and the LETO PRO/PRO RGB. The difference between the non-pro and pro is that the latter includes two CPU cooling fans. The dimensions of the CPUs cooler includes the fan’s width.

This is the first Raijintek CPU cooler. Raijintek’s packaging is minimal with two sheets of foam protecting the heatsink and a kit box with an instruction manual. Along with the mounting kit, you get two Y cables- one for the fans and another for the RGB LED cables. Each fan has two wiring- one is the four-pin connector and the other is the RGB Y-Cable.
