Reeven Kelveros Review

CPU cooling was, is and always will be an important factor determining the overclockability and system lifespan. Reeven with their Reeven Kelveros cooler are trying to cover a wide socket range aiming at performance cooling.

Reeven is a relatively new company that specialises in PC cooling. Let’s take a look at the official website description:

REEVEN is a newly established international manufacturer of PC related products. REEVEN’s product lines includes the best quality of advanced CPU coolers, Cooling Fans, Power Supply Units, PC Cases and many other items. the target of our products will be  a wide range of audience under our philosopohy “Professional Quality Gears”, for products that will withstand the highest demand.

Let’s take a look at the Kelveros’s main specs and features, directly taken from Reeven’s website:

Package and Accessories


The Reeven Kelveros comes in a nice black and golden box that gives this ‘industrial’ feeling. At the top side there is a picture of the cooler and the socket compatibility list, while at the bottom there is warranty information. Finally, at the sides of the box we can find information on the socket mounting clips supplied, specification and features. Overall it is a box that let’s you know everything about the cooler 🙂

Apart from the actual cooler, inside the package we can find:


  • Adjustable backplate for all socket types
  • Mounting kits for all socket types
  • Installation manual
  • Stickers
  • Thermal paste compound.


A Closer Look – The Reeven Kelveros


The Reeven Kelveros utilises the succesful tower design. Overall, it feels a well-built and carefully manufactured CPU cooler. At the top side there is a nice encraved Reeven logo. The fan used here is the Reeven Coldwing 12, a 120mm fan with PWM control for which a Low-High selector is supplied.  In LOW mode the fan’s speed is between 650 and 1300 RPM, while in HIGH it is between 650 and 1900 RPM. The actual speed is automatically adjusted by PWM control. 

There are a total of 60 aluminum fins but the thing to note here is the cooler’s base. The heatpipes are not nickel-coated, they have a different size and come in direct contact with the CPU. Reeven call this Heat Pipe Direct Contact Solution or H.D.C.S. The base plate is completely flat so that maximum surface contact can be made.

Unfortunately, the design of the Reeven Kelveros does not allow a second fan to be added.


Test Setup and Procedures


We tested the Reeven Kelveros on our overclocked i7 920. Installation was very easy especially if following the instructions step by step. You adjust the supplied backplate angle at the back of your motherboard and afterwards you screw the cooler onto it, after of course having placed the corresponding mounting kit on the cooler.

You can take a look of how the cooler looked on our system. There will likely be no interference problems with RAM modules or graphic cards as the cooler is not massively huge and actually it is one of the lightest we have tried.

So we ran idle/load temperature tests at our overclocked i7 920 to determine this cooler’s cooling capability and afterwards we measured noise levels. We ran the fan always at PWM HIGH mode at a room temperature of 20 degrees Celsius.

Our test system was:

Processor: Intel Core i7 920 @ 4GHz
Motherboard: Asus P6T SE
RAM: 6 GB Mushkin 6-7-6-18
VGA: Gigabyte GTX480 1536MB
HDD: Velocity Raptor 150GB
PSU: High Power Astro APT-700
Case: Antec one
Operating System: Windows 7 64-bit

We tested the Kelveros against other coolers of the same category, as well as with the top NH-D14 cooler which is of course more expensive.


Test Results and Verdict

20130119105330 - Reeven Kelveros Review20130119105241 - Reeven Kelveros Review

As you can see from the results, the numbers achieved by the Kelveros are average but it managed to beat some  more popular solutions like the Coolermaster V8. It managed to keep our overclocked CPU under control even under full load conditions. This is a solid start for Reeven, even though there is space for improvement. Do not expect the cooling performance that more expensive models like the Noctua NH-D14 offer.

The cooler was quiet enough for our ears and it could be heard when under full load and with the fan working at 100%.

Costing around 45.00€ across Europe, for someone wanting to replace the stock cooler, the Reeven Kelveros surely is an alternative, as it will efficiently cool down your CPU while keeping the noise down to acceptable levels. We have to admit though that at this price range there are other competitors that will give this extra cooling performance for the same amount of money, but by far it is absolutely worth over the stock cooler and over some even worse cooler models as you can see from the results. It is really a pity that this cooler cannot accept a second fan, it would give a significant boost to the performance. When changing from the stock cooler you can always leave the fan setting to LOW and enjoy some really quiet cooling!


(+) Solid build quality
(+) Relatively quiet


(-) Average cooling performance
(-) Cannot install a second fan

Thus, we would like to give the Reeven Kelveros our Value For Money Award, as it is a cooler that comes with a generous bundle that does not boast extreme cooling performance, but does the job it promises.
