Unboxing and Overview
Since Darkside fans are a store brand of Dazmode.com, and these came directly from them, we begin with a look at the shipping packaging. As usual, click on the thumbnails for a higher resolution image if interested.
The packaging from Dazmode was very good, with lots of packing peanuts and good space around the individual fan packages themselves. No complaints here at all! The actual fan packaging is the same as with the other Darkside GT fans we saw before and I am still not a fan of this. I do understand that costs on top of the fan itself were kept minimal here and the trend continues as we see there is the fan included and nothing else. This I don’t really have a problem with since this is intended to be a radiator fan and one would use screws that come with the radiator itself.
On to the fan itself then:
As this is a “Black Edition” Gentle Typhoon, the frame and impeller are both black colored PBT-ABS resin in composition. The impeller has 9 highly curved blades with the trailing edge having small incisions near the hub to attempt to minimize the deadspot in the center. The corners are closed, and have no vibration dampening pads out of the box but one can use shaped, cut pieces of soft foam if so desired.
The hub is quite large and, despite the blade design, it can cause a decent deadspot in air flow. The front hub measured in at 2.01″ and the back hub at 2.05″, thus making a shroud not a waste of money in my opinion. It also depends on the radiator core and how far spaced it is from the frame but this is something to consider. The fan is rated to consume 0.034 A during operation with a peak draw of 0.16 A. On the 12 VDC rail, that corresponds to 0.41 W during operation and 1.92 W peak. In practice, the 3 fans provided consumed a max of 0.024 A each during operation (~0.3 W) so please plan accordingly. A standard 1 A motherboard header should be able to power 3+ fans by itself, even accounting for peak draw. These are 3-pin fans, so this also opens up a lot of fan controllers although in 2017 most decent motherboards themselves offer good fan control already. Oh, notice that small black thing on the left in the last picture above?
Since I had three samples here, I decided to sacrifice one (after testing was completed, of course) to take a look inside. There is a small circlip that holds the rotor in place on the motor shaft which is what I was referring to previously, and then we can take a look at the 4-pole motor used, the PCB on the back and finally the dual ball bearings used here.
No sleeving of the wires here. It would have been nice to see all black insulation but again this is out of Dazmode, and Darkside’s, hands. It will continue to be a negative in my books, however, as I am judging the product from the customer’s point of view. Dazmode does offer a sleeving service at an additional cost, if you were interested. Let’s see how the fan performs now on the next page.
