Raijintek is a great company that releases cases and CPU coolers at a very reasonable price. Raijintek has recently released a new CPU cooler and we have the pleasure of testing a new RGB cooler on our testbench. The CPU cooler that we will be taking a closer look at is the Leto Pro RGB CPU Cooler. The cooler also comes without RGB fans.

Weight: 925 grams
Heat-pipes: Direct Touch 4 x 6mm
Material: Solder-free Aluminum Fins
Fan Dimensions (W x H x D): 120mm x 120mm x 25mm
Speed: 800-1800 rpm
Bearing Type: Sleeve Dynamic
Air Flow: 56 CFM
Air Pressure: 1.6 mmH2O
Noise Level: 25 dBA
Connector: PWM, 4-pin RGB
Compatibility: Intel Sockets: 775, 115X, 1366, 2066, 2011 AMD: AM4, AM3+, AM3, AM2+, AM2, FM2+, FM2, FM1
Taking a closer look at the box, notice that they box is universal and can be used for both the Leto Pro Black version and also the Leto Pro RBG version.
The back of the box lists all the specifications for the CPU cooler. This cooler does have a 5-year warranty which will make sure you are able to continue using this cooler for your personal system for several years.
While not necessary, there is no padding in the box to protect the CPU cooler from being damaged. Luckily, the CPU cooler arrived without any damage to the cooler or the box.
A Closer Look
The first thing I notice when taking a closer look at the Raijintek Leto RGB is the black coating on the aluminum fins and also the cold plate. This overall black aesthetic will compliment almost any build.
Testing System and Installation
Processor: AMD Ryzen 5 2400g
Motherboard: Gigabyte AB350N Wifi ITX
Graphics Card: Onboard Vega 11 Graphics
Memory: 16gb Gskill Flare X 3200mhz
Storage: 240g Samsung 850 Evo ssd
Power Supply: XFX TS 750w
Case: Cooler Master HAF Evo XB Test Bench
Idle Temps: The temperature is recorded after 5 minutes of idle
Metro LL Benchmark (Very High, AF 16X, No AA, PhysX dis): This is looped into 3 consecutive runs and the highest temperature is recorded
ROG Realbench 15 min Stress Test: This test is accomplished to put a realistic load on the CPU/GPU. It runs LuxMark and Handbrake to stress the CPU, cache, GPU and RAM of your system.
Ashes of the Singularity CPU Test: The CPU test is used to place a great gaming load on the CPU with lots of calculations being made with the many units on the screen during the test.
Rise of the Tomb Raider: This game is less demanding on the CPU and more demanding on the GPU but is a great title to benchmark game performance.
Cinebench R15: This is a great CPU test to use all of the threads on your processor.
The installation of the cooler was pretty straight forward. One difficulty that I did have was getting the screws through the foam on the provided backplate, specifically for the AM4 socket. I am glad that they do have the foam on the motherboard side of the backplate as it provides a good amount of padding to make sure you don’t damage the backside of your motherboard while you are securing the Leto.
While effective, the typical fan clips can provide a little bit of a challenge securing the fans to the cooler. Once they are on, they are very secure. There is plenty of mounting hardware to be able to mount this cooler to almost any mainstream socket.
The following are what I believe to be a great group of real world representative tests to be able to stress the CPU and integrated Vega GPU and lastly the CPU cooler that is attached. The ambient temperature of the room during testing is 18 C. The testing was conducted with the 2400g stock settings, an Overclock of 3.9 Ghz on the CPU, an Overclock of 1500 Mhz on the GPU and lastly both the CPU and GPU Overclocked. During testing the hottest package temperature is recorded.
System Idle (after 5 min of Power On)
The Raijintek Leto was able to keep the 2400g at 23 C and below during idle in all test variations of idle. This is an improvement over the wraith stealth as it was only able to keep the 2400g at 26 C in all test variations of idle.
Metro Last Light (Very High, AF 16X, No AA, PhysX Disabled (3 runs)
15 minutes of ROG Realbench Stress Test
Ashes of the Singularity (CPU Test)
Rise of the Tomb Raider Benchmark
Cinebench R15 (3 consecutive runs)
During testing of Cinebench R15, the Wraith Stealth allowed the 2400g (GPU 1500 mhz overclock) to climb to a toasty 93 C after one run. The Leto under the same overclock was able to maintain a maximum of 69.3 C after three runs.
