Thermaltake ISGC 12 (AF0018)

The new Thermaltake solution – ISGC 12 (AF0018) fan – was developed first of all for the cooler lineup of the same name, which we are going to introduce to you a little later. Nevertheless, you will also be able to purchase this fan separately. It ships in small white boxes made of thick sturdy cardboard. There is a petal-shaped cut out window in the front of the box revealing almost entire fan to the potential buyer’s eyes:

The package also promises “pure silence” – a pretty unique slogan that must have been suggested by the marketing guys, but not the developers of this fan mode. The back of the box shows a photo of the fan, lists its detailed technical specifications and briefly describes its main distinguishing features and peculiarities. The fan is made in China. No warranty is mentioned anywhere on the package.

Thermaltake ISGC 12 comes with four silicone mounting spindles, four self-tapping screws and a booklet with instructions in several languages:

Besides, there is a small rotation speed regulator attached to the fan with a short cable. It is exactly the same as the one in Thermaltake BigTyph14 Pro cooler, for example:

The fan measures 120x120x25 mm and weighs 157 g. It has 9 blades and a rotor with 41 mm diameter:

The fan looks pretty unusual due to glossy white petal-shaped blades. According to the developers, this particular blade shape with a small cutout on the tip of the blade should increase the airflow by 15% and lower the noise by 3%. While the first claim is actually very easy to check out, the second improvement can only be registered by high-precision measuring tools, but by no means by a human ear.

 

The supporting rods of the Thermaltake fan look pretty bulky, especially after the thin rods we have just seen in Noiseblocker products. Wide rods with rectangular cross-section will create an additional obstacle for weak petal-shaped fan blades with small effective surface. The fan frame is quite common with two standing out edges. In other words, we didn’t notice any optimizations here.

Thermaltake ISGC 12 rotation speed can be adjusted manually from 800 to 1300 RPM creating maximum airflow of 58.3 CFM. They claim 1.422 mmH2O static pressure at 16 dBA of noise (it must be the minimal value).

The fans use a new fluid dynamic bearing designed specifically for them. According to Thermaltake, it is not just extremely quiet, but also can work at 50,000 without failing. As you have already understood after checking out a few previous fans in this roundup, Thermaltake’s claimed bearing MTBF is nothing special any more. But maybe it will please us with its extremely low noise?

Speaking of the fan’s power circuit, we should point out that the startup voltage is claimed to be 7 V, current – 0.1-033 A and power consumption – 1.2-3.96 W.

Thermaltake ISGC 12 fans are priced at $15. Judging by the UL number on the rotor sticker, these fans are made by well-known YS Tech Company.

Now let’s continue to the results of our practical experiments:

The new Thermaltake fan turned out quite mediocre and I would even say strange. Up until 660 RPM it worked extremely quietly, practically noiselessly. And then as the rotation speed increases, the noise level jumps up dramatically, which is also accompanied with rumbling of the bearing/motor. However, this fan can still be considered acoustically at 810 RPM, although it creates pretty weak airflow at this speed. Thermaltake ISGC 12 can start at 4.2 V and consumes very little power.
