Raijintek Ereboss CPU Cooler Review
Final Thoughts
Price
For just £26.99 from Overclockers UK the Ereboss is competitively priced and will go head to head with many already popular products from brands like Cooler Master and Enermax. It’s also one of the best looking coolers in this price range.
Overview
I’m really happy with the performance seen here today, while it was nothing ground breaking any way it is certainly competitive in terms of cooling performance for this price range. Idle temps are a little higher than some other coolers, but given the fan is inaudible at low RPM and high RPM it seems like a great tradeoff.
Overclocked performance was impressive for a cooler of this size and while it did get pretty hot it was well in line with what we expected. 4.5Ghz on our i5 is no easy task for a cooler and the Ereboss had the lowest idle temperatures in this test, and essentially matched an Antec water cooler at load. Although I think I would aim for a lower overclock over long periods of time for a cooler of this size.
Silence is golden and the low noise of the slim fan will certainly keep the peace. We couldn’t hear it from a couple of feet away with an open top test rig, so inside a chassis will be even quieter. The slim fan does a fantastic job too, but the combination of heat pipe configuration, fin design and the sleek fan all add up to an impressive end result that performs really well and looks great too.
The fan does sit on top of the ram but can be mounted on either side of the radiator. This also means you can install two fans if you want to boost cooling performance. However keep in mind that ram with tall heat-sinks and the fan on the right of the block could cause conflicts (hardly an uncommon issue with tower coolers).
Pros
- Great design
- Competitive price
- Solid performance at stock and overclocked settings
- Virtually silent
Cons
- None
“The Ereboss is a great start for Raijintek and if this is just a taste of what they have to offer then we look forward to testing more in the future. The price is cheap, the design looks great and the performance is competitive, definitely a bang for buck worthy product.”

Thank you Raijintek for providing us with this sample.
ETeknix has the worst reviewers. They are not picky enough to be handing out “awards.” Anyways. This is a HUGE CPU cooler and what do I want from a huge cooler? Good performance. Seriously, it’s not that difficult. Copper pipes, Aluminum fins, and good fan. What’s wrong with this CPU cooler? Besides the fact that it’s fat, ugly, a block that is going to mess with your ram or cables, and the fact that it’s just plain UGLY? The fan doesn’t fit the cooler, airflow is escaping at the top and bottom of the fins, and they just tried to copy Coolermaster, make it look cool, and did a horrible engineering the airflow. You have to focus the airflow through the aluminum fins to dissipate the heat the fins are spreading from the copper tubes. 30 pounds is like 50 dollars. Yes.. Let’s match it up with some weak ass CPU coolers and give it a “bang for buck” award despite the fact that NO ONE can dethrone a Hyper212 for bang/buck ratio. Stop giving your sponsors awards Eteknix..
We didn’t stack it up against weak coolers, we re-started our charts with new products to facilitate a new reviewer in the section of the site and will continue to add more coolers to the charts over the coming weeks, but if you actually read our methodology page you would have known that.
The numbers are the numbers and the Ereboss gives decent cooling performance, as well as superb acoustics for the price range. Style is subjective so you can’t tell me I don’t like the design, because I do.
I guess we should just stop reviewing all budget friendly coolers, or judging them on their own merits because the Hyper212 is good? And you think that good build quality, nice design, quiet performance, respectable cooling and a low price tag don’t justify a bang for buck award because of other another products performance in a past review? That would be like no one winning an Oscar for best actor because some guy already won it 30 years ago in your favourite film.
Also, just because a company sends us samples, that does not make them sponsors.
You would have better used your time by showing yourself out and closing the tab.
Very good reply ! Right on Peter ! 🙂
The heatsink itself looks like it might perform well. But that fan is garbage. You can’t get much static pressure from a fan that thin.
I’d be interested to see just how much better this cooler performs with a decent fan attached, and maybe with two in push pull.
