This review is concermed with the Revoltec Airguard 120 mm case fan. It is one of my favourite fans, cause of the incredible design, that gives me shivers, I just love it. But let's get more into detail here.
The revoltec airguard is a fan with a diameter of 12 centimetres or 120 mm. It is black with an incredible looking revoltec logo in blue at the motor of the fan. The black plastic of the fan is very well made and is semi shiny. Looking closely to it you can notice the plastic is not smooth but has small textures on it and it looks very well and not cheap at all. The fan, looking closely or from an distant position, with the black frame and wings and the blue logo just looks mind blowing in my opinion and is a good reason to owning the fan. The cable has a very well looking protection, so you do not see the cable but some cover which is protecting it. So summarised the design of the fan is great.
Noise and airflow:
The revoltec airguard is not the quietest fan and spins with a speed at about 1200 rpm. The airflow is therefore very good and if you use several of these you will be able to cool your case pretty well. At 12 v the fan is not absolutely silent, but still relatively quiet and you can notice the airflow and a quiet motor noise, which I like a lot, too. The motornoise calms me down, cause it is a consistent and quiet gliding sound which is very pleasant to hear. If you have loud components on your computer you won't be able to hear it, but if your over components are silent, this is what you will hear. From far away it hardly can be noticed though. At 7 v the fan is absolutely quiet and wont produce any noise. The airflow will not be as good, but still enough to chill your harddiscs some degrees or use it to take away the air at the backside of your case.
The fan is very good when it comes to airflow, but for great cooling of a gpu or cpu I would recommend a noiseblocker with 1400 rpm or a scythe slipstream, since these have quieter engines and spin faster, while producing the noise of the airguard or a bit less. This fan is still very good and though and people who want a quiet fan, but not ultrasilent will be happy with it.
I can recommend the Revoltec Airguard, since it has a unique design and is very well made. The noise leven is low and it produces a nice calming sound which might even be better then no sound at all. 5 Stars here
You may look at the Revoltec airguard Pro series, a bit quieter.
