Who better to design a great case fan than the innovative and forward-thinking case manufacturer, InWin, Wait! Didn’t I do that introduction already? Today I have 2 new and completely different case fans from InWin, the Sirius Pure and the Sirius Loop. As 120mm case fans go, these are lookers with the performance to back it up. So, at the risk of humming that Michael Jackson/Bill Bottrell song: It don’t matter if you’re black or white. Let’s see what we find.


Specifications taken directly from the InWin product pages:


Cooling in mind, Larger blades and thinner frame with center cooling holes
Dual Addressable Loops
Intelligent PWM Cooling
Shockproof Rubber Stands
Single or Triple Fan Packs
ARGB “One-Click” Modular Controller

High Airflow Case Fan
ARGB Lighting Effect
Included Controller allows Fans to Function without an ARGB M/B
Intelligent PWM Cooling Design



As usual, we start with the outside of the box. They are surprisingly similar in design with the black vs white difference. The top and sides have the “Sirius Loop” or “Pure” and with the standard InWin branding. The front has a striking picture of the fan, along with the badges stating compliance with different RGB systems. The back succinctly lists the features, contents, specifications, QR code, and an image of the modular connector. The boxes are well up to the high standard of informative and impactful promotion. The QR code leads to the a manual, though I didn’t find it to be all that thorough.

The top of the box holds the fasteners, screws, rubber pads, and the 1 click controller. They are well packed in to prevent movement and not a bit of space is wasted. The 3 fans are tucked into sleeves and hidden in the box bottom. The colour matched screws and rubber are a nice touch.



Everything you need to install the 3 fans is included in the box, except a description of what each wire does and if both are required. As each fan has 2 wires attached it is not easy to cable manage and can be a bit of a tangle tease when sorting the cabling .

These fans can daisy chain and all 3 can link up to one motherboard header, though hopefully to hide some of the wires you can route them/hide them behind the motherboard. Or you use the one-click controller as it uses a single motherboard connection and a SATA power connector instead and can also be tucked away behind the motherboard tray. However, it was challenging to have the one click controller on the outside of the case and keeping at accessible, while trying to keep everything looking tidy.



As usual, the numbers printed on the box are accurate but describe ideal conditions, not necessarily what you will get. That said, they are very acceptable numbers, pushing 50 CFM and maxing out at 27 dBA. The PURE list on the website that they vary with PWM to give 13-27 dBA (Max.) / 19 dBA (Normal).

Both 120 LOOP and PURE list:

Speed Mode PWM 500~1800 RPM
Air Flow 50 CFM
Air Pressure 1.67mm/ H2O
Noise Level 27 dB(A)

With that amount of similarity, picking one over on performance is unlikely. The beautiful crystal Saturn fans I reviewed last did push more air but at the cost of being louder, so there are options based on what your preference is.

That means picking between the PURE and the LOOP is down to aesthetics. And they are pleasing in that category. The black is quite dark and the white is a pure white, probably why they named it such. As they are usually housed in a case, the difference will be even smaller as the housing of the fans will not be visible. If your case is based on a white theme the choice is obvious. In my mostly black case the white is a nice contrast and definitely stands out. It makes me desire some more white highlights in other visible areas. The lighting is visible equal from inside or out because of the dual RGB rings. They make the inner and outer view much more intensely lit. One thing I can not test due to the lack of aRGB controller is if they can do different light colours on the inner or outer rings. Let me know if you test this.


The video shows the lighting in the “real world” of my case with sound to give a further insight. This is in my open case, so yours will vary, again this is just an example of the fans in the real world.

And a few of the differences highlighted in my test samples though it seems they will all be of the new type seen on the white fans going forward:

Price and Availability

Right now on Amazon you can pick up the InWin Sirius Pure for $48 or if you prefer the Sirius Loop, you can pick them up from $40. 


I was impressed that with the Sirius Loop & Sirius Pure, it does not matter if your motherboard does not support RGB as the included controller with these products gives you this functionality out of the box. An additional plus is the ability to daisy chain the fans together which not only helps reduce the overall amount of cables but of course lends itself towards the RGB affects being synced across the fans. Considering both these products can push some serious CFM, whilst maintaining a low DB rating, is a huge plus and would be an easy win for any system builder or for someone looking to maintain great airflow performance while keeping noise to a minimum. Everything considered, the price point for the Sirius Loop & Sirius Pure is fantastic, I would definitely rate these as a Must Have for those planning a system build or for an upgrade project.

ARGB for any motherboard.Using two cables needs a bit of additional management to keep them out of the way.
Good cable management with the daisy chaining.
Good airflow vs noise ratio.
Competitively priced.
