Bgears B-blaster Fan Review

b_0_0_0_00_images_stories_BgearsB-Blaster_BGEARS-140MM_01.jpg

The B-blaster is Bgears' newest line high performance 2-ball bearing fans shipping at a budget price.  It aims to make a splash in the price-to-performance market, and they are making a strong case for themselves. A wide range of sizes means that you can surely find a spot in your case if you are in the market for new fans.

The B-blaster fans come in a wide range of sizes, and comes out at the same time as the B-ice fan, which bears the same blade design as the B-blaster 140mm with a little extra pizazz.  For the price, and their specs, they look to be very competitive in the price-performance ratio market.  2-Ball bearings ensure low vibration and also long lifetimes and quiet operation.  The inclusion of 3-pin to 4-pin molex connectors are a nice touch to complete the package.

This picture shows the entire size range of the B-Blaster fans being offered by Bgears.  As you can see, they come in very colorful and pleasing packaging, and it's not even the "hack saw packaging" that requires you to destroy the packaging to get open,  just "pop" it open and you are good to go.  Sometimes it's about the little things!  We will now focus our attention on the 120mm version fan, since they are all basically scaled versions of each other, and 120mm fans are still currently the most popular fan size.  Keep in mind as we proceed that fan speeds and noise levels, in addition to other specs such as flow rates and pressure will vary between these, so look up the specifications for the size of your particular interest and compare to how the 120mm performs. The an blade design on the B-blaster fans are very similar to the "trending" variable pitch blades which have a higher angle of attack near the hub and as the blade speed increases away from the motor hub, less pitch is needed.  This helps reduce vortices and drastically reduces noise while keeping an even flow through the fan.  You may also notice that the blades have a semi-gloss finish while the enclosure has a flat black color.  The inclusion of a 3-pin to 4-pin molex adapter is always much appreciated whenever I receive a new fan, I always like to have options.  Here's another look at the blade design, and you can once again notice the semi-gloss finish on the blades, it looks less textured when not subjected to a flash.  The Bgears logo is also proudly displayed over the motor hub.

This is the other side of the fan, also displaying another angle of the blade geometry, and a better look at the power cable.  It isn't sleeved, but it's very tidy, looks nice, and is pleasantly flexible and very thin, so cable management should be a breeze (literally).


Testing

Our testing will be subjective in nature, as we currently don't have accurate enough equipment to make precise comparative decibel and airflow measurements.  We isolate the fan from other airflow and noise influences via a long fan extension, and place it into a small enclosed box for noise evaluation and a controlled airflow setting.

 

These fans, being in a relatively budget price range, but targeted at the high performance market had me intrigued as to how it would perform.  The answer to that question is, quite simply, quite well!  The two-ball bearings give the fan very smooth operation with very little vibration noticed when holding it in an array of orientations.  It also has a great "free spin" capability, and what I mean by that is that it will spin for a long time after power is removed, which often is a preemptive sign of the quality of the bearings, which points to smoothness of operation, as well as expected lifetimes.  Two-ball bearing fans often last a very long time, and priced comparably to many other sleeve-bearing fans, these are a no-brainer.

The airflow is also very good on this fan, and it does so at fairly low RPMs, which also treats us to low-noise operation as well.  It does not push as much air or its noise level as some of the other fans we have tested, but it's quite close, and at the price range it is listed (around $10), would certainly best nearly all of its competition.

 

Pros:

  • Two Ball Bearings
  • Smooth, low vibration operation
  • Quiet
  • Should provide good lifetimes
  • Clean appearance

Cons:

  • For it's price range, any downfalls are relatively negligible, no real cons with these!

We would like to thank Bgears for providing these fans for us to test!
