A few notches under the top-of-the-line TISIS is the RAIJINTEK Ereboss, what makes it unique is that it uses a thin (13mm) fan, cools really well and isn’t that heavy on cost and weight.
Here’s what it looks like, the 13mm thin fan looks great on the unit. Don’t worry about the fan looking a bit low as the height can be adjusted. The fan is held in place by the rubber stub, this is helpful in reducing vibration but it might be a problem should the stub break, go missing or age with time.
Here’s the top view, nothing unusual here as this is what a air cooler heatsink usually looks like.
Here’s the view from the bottom, the nickel copper base is connected to the large dissipating fins through 6x 6mm Heat-pipes.
Here’s the fan on its own, it’s a low-RPM (650~1400) PWM fan with CFM up to 56.55.
Lastly, here’s the packaging for the Raijintek Ereboss.
Below is the specs of the Raijintek Ereboss as see on the official product page.
Benchmarks
The performance was tested on an Intel Core i5-6600K overclocked to 4.3Ghz at 1.275 vcore with room temperature set to 25°C and the system was tested with a 10bit to 8bit video conversion test. Below are the results.
| Cooler | Idle (°C) | Load (°C) |
| Raijintek Ereboss (AUTO) | 28 | 56 |
| Raijintek Ereboss (MAX) | 27 | 56 |
| Raijintek Ereboss (SILENT) | 27 | 59 |
Looking at the figures above, you’re good to go with SILENT fan mode as it cools very well, considering it was tested on an overclocked processor.
The Verdict
The Raijintek Ereboss retails at USD 53 – a really solid price for a CPU cooler that performs this well. I like it for its simplicity, and not to forget that beautiful thin fan that’s in red.
