Furious Vardar.. Let that sink in for a bit while I take a break from having finished writing the review of the Vardar F4-120. If you haven’t taken a look at the PR note from EK describing these names as well as explaining the name, now’s as good a time as any. Knowing what Vardar means, I can also relate to what a Furious Vardar would be and that makes me just ball up my fingers into a protective stance. A 3000 RPM variant of these Vardar fans (which blow a lot of air even at lower speeds) is not necessarily for everyone. In fact, I was having a hard time trying to figure out what other fans could be used to provide context. Silverstone had sent along an FM121 fan which was very impressive and there was also the Noctua NF-F12 IPPC-3000 PWM. But aside from these, there aren’t very many high speed fans that are consumer oriented. The recently reviewed Blacknoise NB-eLoop B12-4 barely makes it into this RPM range as well. Do I include the Deltas and the Sanyo Denkis? If so, where do I stop? But before I digress further, let’s get back to the subject at hand here: the FF5-120. Thanks to Derick and Niko from EK as well as Hank from Performance PCs for the fan sample.

Let’s begin by taking a look at the specs courtesy the product page:

We see that the fan has a double ball bearing which I would have expected to last longer than the advertised MTBF of 50,000 hours (do note that the specified operating temperature there is 40 ºC and most consumers will have a lower temperature than that). No mention of warranty here, although I do know EK has a standard 2 year warranty on most of their products as mentioned here. The PWM duty cycle is 40-100% as was the case with the F4-120. So far everything has been on par with the other Vardar 120mm fans seen so far. But that’s pretty much where things begin to differ- a rated power draw of 5.64 W is a far cry away from the immediate lower model, the F4-120, at 2.16 W. Also unique to this model is a fiber-glass strengthened impeller (the blades) to ensure no issues arise from operation at 3000 RPM. Let’s now take a look at the fan in detail on the next page.
