SilentiumPC Sigma PRO Corona RGB Fan Kit Review

Final Thoughts

How Much Does it Cost?

Although we have not been able to find any confirmation, we understand that the SilentiumPC Sigma PRO Corona RGB kit retails for a price in the region of £25-£30. In terms of a fan kit, this actually represents excellent value. Remember, you can easily spend over £10 on a fairly standard system fan. As such, to get 3 for less than £30, which incidentally not only has RGB lighting but lighting capable of sync motherboard support is really great.

Overview

From the packaging to the fan aesthetics, we really like this fan kit. With 3 fans, this should be more than enough to cover the needs of most of the high-end chassis kits and with the nice bright RGB lighting effects (and design of the fans themselves) these do a really good job of standing out from the pack.

Performance

Given that these are system fans, performance is really relative to what the fans can do. With a 33.3CFM airflow, these fans are neither overly good or bad in terms of airflow. At a maximum speed of 1500rpm though, that is hardly surprising or unusual. With a 3 pin power adaptor, you do, of course, not have access to the high-control offered by PWM connectors, but regardless of which, the performance should be more than suitable for your needs.

Acoustics

The system packaging does not indicate an operating noise level of DBA. From our testing though, we found that the fans at full speed operated at around 38-39dBA. While not overly loud, these are not exactly quiet either. That being said though, the chances that you would run these at 1500rpm is exceptionally unlikely. At lower speeds, the fans are impressively quiet.

Design

It is again difficult to find any fault. I really like these system cooling fans. The packaging is exceptional. The fan design is relatively unique and even the RGB controller is surprisingly good. We’re not saying that these fans are faultless, but it’s hard to find anything in the design to criticise either.

The RGB lighting design is one of the best I have seen. It is bright and bold while also somehow remaining understated. It again speaks of some very clever decisions made in terms of the design.

Should I Buy One?

When it comes to system fans, it’s hard not to exaggerate just how much the market is flooded by poor quality and noisy options. For something in this price range, you are literally spoilt choice in those regards! The SilentiumPC Sigma PRO Corona RGB Kit, however, is more than a few steps above this. While they are not high-performance, you wouldn’t expect that for less than £30!

When you consider that you’re getting 3 nicely designed fans, with some excellent RGB effects, these really do represent an excellent upgrade option for many standard system cooling fans.

Yes, there are better options available, but not within this budget! This is the exact type of product our ‘Bang For Buck’ award was made for!

Pros

Fantastic packaging and presentation.
Fan design is nice and somewhat unique.
RGB lighting effects are bright and bold while also being understated (albeit your colour palette is rather limited).
Good acoustic performance at standard operation.
