MP3 SOUND RECORDINGS
These recordings were made with a high
resolution, lab quality, digital recording system inside SPCR's
own 11 dBA ambient anechoic chamber, then converted to LAME 128kbps
encoded MP3s. We've listened long and hard to ensure there is no audible degradation
from the original WAV files to these MP3s. They represent a quick snapshot of
what we heard during the review.
These recordings are intended to give you an idea of how the product sounds
in actual use one meter is a reasonable typical distance between a computer
or computer component and your ear. The recording contains stretches of ambient
noise that you can use to judge the relative loudness of the subject. Be aware
that very quiet subjects may not be audible if we couldn't hear it from
one meter, chances are we couldn't record it either!
The recording starts with 5~10 second segments of room ambiance, then the fan
at various levels. For the most realistic results, set the volume so that
the starting ambient level is just barely audible, then don't change the volume
The Reeven Kelveros' stock fan, despite being a high speed model, has decent acoustics once the speed is turned down. That, unfortunately, is the only compliment we can pay. It's impossible to run the fan at quiet levels while maintaining good performance because the proficiency of the heatsink is decidedly poor. Of all the tower heatsinks with 120 mm fans we've tested over the past few years, the Kelveros is second worst only to the AC Freezer Xtreme, which sold for considerably less.
The main culprit appears to be the mounting system a backplate doesn't necessarily equate to good contact between the heatsink base and processor heatspreader. The mounting clips are thin and weak, and attached to the bottom of the heatsink, rather than over the top of the base. When the screws are tightened, the metal bends downward, so most of the extra pressure is applied to the corners, rather than the center where the majority of CPU heat is generated. Having to flip the motherboard upside-down also makes installation difficult, particularly when attempting to center the bolts so no corner is favored over an other.
Availability is also an issue. We found only one place actively selling the Kelveros, a Japanese site listing its price as ¥ 3,980 or close to US$50. At this price, no one should even consider purchasing it. The Kelveros has nothing to distinguish itself aside from its looks.
As much as the Kelveros disappointed, the Arcziel managed to fail even more dramatically. It's the first CPU cooler we can recall that could not be installed on our 1366 platform due to incorrect mount sizing. We then resorted to testing it on our LGA1155 test platform for smaller coolers, and it failed to surpass the performance of some heatsinks barely half its size. The fan isn't very good, either, with tonal elements at various speeds.
The fundamental design of the heatsink seems flawed for a down-blowing model. The fin-stack is very thick with tightly packed fins, creating a big obstacle for the fan to push air through. In addition to being a tall cooler, the fan is raised far off the heatsink surface, decreasing its cooling capability further. The rigid plastic clips used to keep the fan in place are terrible, breaking so easily that Reeven provides an extra set as part of the accessory package. We started off with 8 and after a couple of careful fan swaps, were left with just 3.
The Arcziel too seems to only be available in Japan at the moment, with a retail price of ¥ 2,131 or approximately US$27 after conversion. With all its problems, it might be worth buying at a 50% discount. It is after all, still better than a stock cooler, though is incredibly inefficient for its size.
Reeven has made the most underwhelming entrance to the competitive world of aftermarket CPU coolers we've ever seen.
