For the official technical details, please visit the official SilverStone web page by clicking here: SilverStone Air Penetrator SST-AP141.
Air Penetrator was released about 2 years ago as a model with two dimensions( 120 and 140mm ) and same colour scheme but later other models were released with different backlight and not so long ago I tested one of them. The model was SilverStone Air Penetrator SST-AP121-GL with green back light and today I will test and review the basic model with size 140mm.
SilverStone Air Penetrator SST-AP141 was provided to me in the same stylish black carton box with a see through plastic cut, through which you can see the fan structure, with some basic information on the front. The box is absolutely the same as the one for the smaller model.
Again, the full technical details were on the back side of the package.
As I said in the first review, the original Air Penetrators were released as a structure of:
- On the front view it looks like a standard black platic frame but on the back it’s designed to channel the air by focusing it like a column.
- UV reactive transparent propeller offering seven blades with not so aggresive angle and not so wide as the 120mm version. Unfortunatelly, this model doesn’t offer a backlight.
Seen from the back:
As part of the SilverStone Air Penetrator series, this fan should provide absolutely the same features, except the backlight like the smaller model but with better performance and bigger airflow level. According to the official details SST-AP141 rotates again with 1500 revolutions per minute with airflow level of 64.34 CFM, which is almost double than the 120 version, static pressure of 1.55 mmH2O at noise level of 30.1 dB.
The technical details don’t seems to be that good, but I already had the same situation with SilverStone Air Penetrator SST-AP121-GL and after I finished testing it, I was amazed by its performance.
So, is this going to be the same? Probably….
Again, powering and regulating the fan is done by a long sleeved in black cable with a 3 pin connector, which can be installed everywhere inside the case.
The standard package offers:
- Four metal screws
- Four rubber screws
The tests will be conducted in my standard way. I will mount the sample and test it at 5V/7V/9V/12V and my goal will be to check the authenticity of the technical characteristics given by the manufacturer. The product will be tested under close-to-perfect conditions, not taking into account any external factors. The results achieved during the test can in no way be the same if the fan is mounted on a cooler or on the case fan hole of any modern computer case. I will measure the amount of air going through the fan for one hour and its speed. For this I use a fan controller, a voltage meter, an anemometer and a stand made specifically for this purpose.
The test results are shown in the following charts:
Airflow through the fan at 5V, 7V, 9V, 12V
Propeller rpm during the tests at 5V, 7V, 9V, 12V.
The anemometer showed the following air speed:
After mounting the fan onto the stand and leaving it to run for about 30 minutes at maximum speed, it was time for the tests to begin.
As with my other tests, again I started with a gradual increase of the voltage through the Lamptron FCT starting at 0V and the SilverStone Air Penetrator SST-AP141 made one full revolution at 2.6V and to conduct the first test I had to increase the voltage to 5V.
Test at 5V:
The test started and after the fan had been rotating at 5V for about 3 mins it reached an average of 810 revolutions per minute and airflow level of 44.64 cubic metres per hour. The fan was absolutely silent.
Test at 7V:
In the second test conducted at 7V the fan reached an average speed of 1020 revolutions per minute and airflow level of 61.92 cubic metres per hour. Again, the fan was absolutely silent.
Test at 9V:
The third test was conducted at 9V and at this voltage there was a little noise from the air passing through the fan at 1260 revolutions per minute and airflow level of 75.84 cubic metres per hour.
Test at 12V:
Last test was conducted at 12V and the model reached its top performance of 94.08 cubic metres per hour at 1530 revolutions per minute. At this speed the noise increased but to a reasonable level.
Again I will do a second test by mounting the fan on a cooler just to test the channeling feature.
For this test I will use my computer:
CPU: AMD Athlon X4 620 at standard frequency of 2611 MHz.
Motherboard: GigaByte 790X-UD3P
Video card: Sapphire 5830 Extreme 1GB DDR5 256bit
Memory: 2 x 2GB Apacer 800 MHz
Hard drive: Kingston SSD SV100S264G
Case: Cooler Master HAF 932
Power supply: Cooler Master Silent Pro 600
Cooler: Reeven Arcziel RC-1203
Thermal paste: Gelid GC-Supreme
The tests were conducted in an open system with:
- 230mm fan on the front panel putting fresh air in and spinning at about 700 rpm
- Room temperature of about 28 degrees.
I will install Reeven Arcziel RC-1203 and do tests at default frequency 2611 mHz SilverStone Air Penetrator SST-AP141 and Enermax Cluster 140mm in two type of tests:
- Fan attached to the CPU cooler
- Fan at 300mm away from the CPU cooler in straight line mounted on my fans test stand.
Both competitors together:
So, let’s see the results:
The results from the tests with SilverStone Air Penetrator SST-AP141 attached to the CPU cooler:
The results from the tests with SilverStone Air Penetrator SST-AP141 not attached to the CPU cooler:
The results from the tests with Enermax Cluster 140mm attached to the CPU cooler:
The results from the tests with Enermax Cluster 140mm not attached to the CPU cooler:
The test results have been summed up in the following charts:
And the fan speed during the tests:
Oh, I guess it is time for me to express my own conclusions about the results, the appearence and the structure of SilverStone Air Penetrator SST-AP141.
- Performance: As we already saw the SST-AP141 has absolutely the same features as SST-AP121-GL but the model is bigger, with almost double airflow level and noisier. The interesting thing here is that when both of the 140mm fans were attached to the Reeven cooler they performed the same even though Enermax had 50 cubic metres per hour more air passing through the fan. Yes, it’s like this because the CPU was not overclocked. If it was then the results would be different.
- Noise level: When I tested SST-AP121-GL I saw good performing and almost impossible to hear fan, but here the results are different. SilverStone Air Penetrator SST-AP141 was absolutely silent at 5 and 7V tests, but at 9 and 12V tests there was a noise and increasing together with the voltage.
- Apperance: All I can say is nice appearance which can be really boosted if the fan is mounted close to a UV CCL or LED strip. Then the propeller starts to glow really beautifully.
Before I continue with the reward I will just copy-paste my words from the first review. Only because this model performs in the same manner.
SilverStone Air Penetrator SST-AP141 is a unique high-tech 140mm fan supposed to be installed on any front case fan slot to provide a column of fresh air for all of the hardware inside the case. I believe best scenario for this model is to be installed as a HDD fan that will cool the VGA too or as a main cooling unit for a machine inside HTPC cases like SST-SG05 just because the channelling technology is really working. And I can say with hand on my heart that it’s possible to feel the airflow at one meter away from the fan.
I can add too, that this model can be mounted on a CPU cooler, cooling processor working at default or some average overclocked frequencies.
The only disadvantage of this fan is the lack of PWM regulation, but after I saw it’s performance I can say it’s not needed.
I think SilverStone Air Penetrator SST-AP141 deserves the following reward:
SilverStone Air Penetrator SST-AP141 has been added to the 140mm catalogue.
Official price (MSRP): 15.33 euro
I thank Silverstone for the test sample.
