Now onto the fans that are supplied with this case, they aren’t standard OEM cheap ones, they are BitFenix Spectre fans, which cost about £5 to buy separately. These fans have fluid dynamic bearings, which essentially means that everything is kept running nice and smoothly and this helps the fans to have a longer lifespan and more silent when running. The fans are made out of thermoplastic crystalline polymer, which is essentially a matte finish, so they are also high quality in terms of looks. According to BitFenix, here are some important figures for the Spectre fans:
Noise - 20 dB-A
Speed - 1000±10% RPM
Airflow - 43.5±10% CFM
Air Pressure - 0.62 mmH2O.
Lets compare that information to an Antec tri cool 120mm fan, which is used in the Sonata 3 and the P182!
Stats taken from Silentpcreview (unfortunately no air pressure readings):
High RPM:
Noise - 36 dBA
Speed - 1930 RPM
Airflow - 53 CFM
Medium RPM:
Noise - 27 dBA
RPM - 1430 RPM
Airflow - 36 CFM
Low RPM:
Noise - 20 dBA
Speed - 870 RPM
Airflow - 21 CFM
Noise Levels:
This is one of the most important things for me when it comes to deciding which case to get! The Raider is louder than my Sonata 3 by a very small amount, however you really have to listen and pay attention in order to notice the difference between them, this is with the Antec tri-cool 120mm in my Sonata 3 set to low and the Raider set to low as well, this is pretty impressive I have to say considering there are 3x120mm fans in the Raider as opposed to just the 1x120mm fan in my Sonata 3!
Even when turning the fans to high for the Raider, it is still exceptionally quite! At first I thought “this can’t be right, I can barely hear any difference at all between low and high”. I even thought to myself the controller for the fans must be broken or not all of them are increasing in RPM as the difference is very subtle but just about noticeable if you pay enough attention. I even had to take the side panel off and put my head near the fans to be absolutely sure about the noise and even placing my hand at the back and front in order to see if there was an increase in airflow! The noise levels are even more impressive considering the mesh design/panels, making it is pretty much open from the back of the top to the bottom of the front.
The Antec tri-cool set to high is extremely noisy. The P182 with every fan set to low apart from the bottom (medium speed) is slightly noisier than the Raider (when fans are set to low), judging by my hearing, this is how I would rate them for noise levels:
High fan speeds – Antec P182 > sonata 3 > raider
P182 being the loudest and the Raider being the quietest
Low fan speeds – sonata 3 > raider > P182
Sonata 3 being the quietest and the P182 being the loudest
However with the fans set to low on the Raider, I can hear the GPU fan much more now when it is under heavy load i.e. gaming, as opposed to the Sonata 3, this is due to the thin flimsy side panels on the Raider.
If BitFenix made the side panels a bit thicker, this would not be as much of an issue then. The open design of the mesh panels at the top probably also play a part in this.
The main thing about these BitFenix Spectre fans is that they are super quiet at low and even high settings!
Here are some decibel readings that I took on my Android Smartphone (Samsung Galaxy Spica/i5700) using this Android app:

Firstly, DO NOT put too much thought into these readings, as they are not going to be as accurate as a proper decibel meter, this is to just try and show you the difference in perceived sound between the fan speeds.
The distance that my mobile was placed (with the microphone facing the cases) from the case is 19cm, this is roughly how far I sit from the case.
Going from left to right, the fan increases from low to medium and finally high speed:
Here is a chart for the decibel readings chart:
Sonata 3:
P182:
The bottom fan in the P182 was kept on medium through out the tests
Raider:
Due to the P182 bottom fan not being changed at all, you could assume that from the medium decibel reading for both the Sonata 3 and the P182, that the difference could be -/+ 1 for the low and high speed tests.
