Introduction:

Sometimes computer users want better cooling, so many companies produce fans to fill in empty slots in cases or upgrade stock fans. Users may also opt to replace heat sink fans for better cooling and/or noise performance. When looking for good fans, people should take note to the type of bearing it comes with. Generally, a sleeve bearing is the worst and should only be mounted vertically. Rifle bearings are better than Sleeve. Ball bearing is even better than both, with Fluid and Magnetic bearings also being good. The bearing type affects lifespan directly, and generally the operational noise, air speed, volume, and the noise generated by the fans are also very important. The impeller blades and hubs both directly affect fan performance as well - large hubs create dead spaces when used on devices such as radiators and heat sinks without shrouds. Fan blade design can change the noise frequency to make fans sound quieter, or boost airflow. The fan reviewed here today is the Evercool Rifling 80mm fan, which has 80mm fan mounts with a 92mm form factor.

 

Closer Look:

Immediately on the front cover is the big silver logo Evercool Rifling Fan, with a red 'Powerful & Silent' underneath it. 17dBA hovers over a soldier who is gazing through a scoped rifle on a bipod. Underneath the red circle which reads 'Special Rifling Design', the package reads: "The unique design makes the air pressures more stonger to reates high dissipation". Grammar and typos aren't as bad as they were on the Evercool Transformer 4, but are still present. Rotating to the back shows a diagram of how the fan blows air. Continuing on down, the specifications and features are laid out. Lifespan isn't mentioned, but the fan blows 24.4CFM at <17dBA. The fan device is made in China and is RoHS compliant.

 

 

 

 

 

The only included accessories are four black fan screws and male-to-female Molex adapter with 3-pin fan header.

 

Let's rip this clamshell package open and examine it!

Closer Look:

Other than the clamshell packaging, all that is included is the paper insert that's visible in the package, the fan, and male-female Molex to 3-pin adapter with four black fan screws. The fan is plastic and has been painted a dark silver color that Evercool calls Metal Black. The fan housing has grooves cut into it, and is angled like a bowl. The impeller is a standard design with seven blades and average hub. The fan bolt holes are open. The impeller hub has a black Evercool sticker with the Rifling Fan and Powerful & Silent motto on it. Rotating to the back shows a purple Evercool sticker with model number and 12V 0.10A power ratings. The bearing has an approximate lifespan of 40,000 hours. The power cable is sleeved, although the fan here came with the heat shrink accidentally slid off of the sleeving.

 

 

 

 

 

 

 

The fan housing is shaped to help the impeller generate more pressure, while the grooves notched inside are also intended for the same purpose. The fan holes are for 80mm mounts, but the size of the device itself takes up a 92mm area which may be problematic for certain applications which require 80mm form factor fans.

 

 

With that done, let's get a look at the specifications!

Testing:

The heat sink used for testing the fans is the ZEROTherm Core 92 cooler, and the competition is a mix of 80mm and 92mm fans. Coming with the heat sink is the Power Logic fan, which is a 92mm fan. The Evercool Rifling fan is a 92mm fan with 80mm bolt holes, and the Gelid and Antec fans are both 80mm fans. The ambient to test the Evercool fan was 75F. To stress the heat sink and show the fans performance better, the CPU was overclocked to 3.33GHz with approximately 1.26V. Idle testing required idling in Vista Ultimate with the average of the four cores reported by Real Temp 3.00. For load testing, the processor is loaded with Prime95. All testing is performed in a case, not a test bench - results should be similar to what users can expect.

Gelid Silent 8

 

 

Overall the Evercool Rifling fan did a good job in the charts, performing averagely in the idle test and performing equal to the Antec offering in the load test. Performance was similar to the Gelid Silent 8 Thermal Controlled fan, which has similar specifications, but is a true 80mm fan.

Conclusion

The Evercool Rifling Fan RF-8 did respectably in testing, performing quieter than the case fans and performing as well as a fan with both a higher CFM and noise rating and in the load testing. The bearing is improved over sleeve bearing and has the second highest lifespan of Evercool's fans with 40,000 hours. The shape can be awkward, but if users want more performance out of a 80mm mount then this fan provides a solution. The fan performed well, but it does have some quirks. The packaging did have grammatical problems and typos, and the fan cable sleeving came disjoined from the heat shrink. The paint chips easily as well, but paint on plastic is always hit and miss. Overall, this fan got the job done and seemed to do it well.
