The latest case fans to go under the wire at Verdis Reviews are the Noiseblocker Multiframe series. The manufacturing company is a specialist in the cooling department and so we’re expected these fans to be really exceptional products especially as the company is known to make changes to their products in order to make improvements. Let’s see how they shape up…

Contents & Packaging
Firstly, I must point out that Noiseblocker kindly provided four fans which are effectively the same but just have different airflows or connectors (for example PWM).
Therefore, in order to review them I will look at, in detail the M12-S1 and then compare all the fans in testing. Let’s crack on with the review…
The packaging is very clever in my opinion, as Noiseblocker have made it seem attractive and appealed whilst only using black and white. The majority of the front is a cut out clear panel which shows most the fan contained inside. To the right of the cut out, there is a white skeleton of the fan showing the construction and shape – it looks pretty good.
At the top there are the usual company logos with a little information about the particular fan model at the bottom such as airflow or noise levels.
The reverse of the box is a little more mundane which a few translations of the short blurb about the product. Finally, at the bottom there is a specification table along with several logos and the company website and contact details.
There aren’t many accessories at all with the fans except a few screws in order to attach them to a chassis.
The Product – Noiseblocker Multiframe Series
The shape of the Multiframe series is quite unique as instead of employing the standard square shape, it is actually slightly rounded with the rubber mounts with the holes in stick out a little on the corners. However, this is not merely an aesthetics feature but reduces the surface area in contact with the chassis.
The impeller is the usual seven blades constructive which the standard for most 120mm fans is. The colour of the blades is a translucent black-grey colour which allows some light to travel through it. The colour is definitely more interesting than just a plain black and white fan.
The blades on the fan are aerodynamically optimised and so can spin at a much higher rate to achieve greater airflow if required. Moreover, they have an anti-dust surface to try and prevent them getting clogged up with dirt – after all who wants to open up their case only to find their fans all covered in grime and dust.
The back of the fan is very similar but you can see the back of the bearing which is covered with a sticker emblazoned with the Noiseblocker logo and a few extra details. The cables are also visible from the back giving a burst of red and yellow colour.
The bearing is an NB-NanoSLI bearing which is supposedly noiseless as it doesn’t create much friction when it spins. This is certainly a bonus for users wanting to achieve ‘silent cooling’.
Looking at airflow, it varies for all the different fan models so that you are able to select one that is appropriate to both the level of cooling and level of noise you wish to achieve (as greater airflow by definition results in an increase in noise outputs). Moreover, the PWM has a range of airflows which are of course dependent on the temperature.
Directly in the middle of the impeller is another sticker (exactly the same as the one on the back).
In the corners, the so-called structure borne noise absorbers that are constructed completely of rubber are meant to stop any vibrations being transferred to the chassis and thus amplified. They are basically doing the job that rubber mounts do but seem to be a much better idea as the mounts often proves very fiddly to install. Whereas, this concept allows the user to still use screws but also gain the bonus of the anti-vibration technology.
Noiseblocker have also come up with the magic number of 30% for which they claim their noise reduction has achieved, coincidentally this is supposedly much higher than all other products too.
Overall the fans range from an MTG 130,000h to 160,000h so they are up there in terms of life-length and are supposed to maintain high performance throughout this period.
Finally, all the fans use the 3-pin connection method except from the M12-P – the PWM version.

Installation as with most fans is exceptionally simple and even more so for the Multiframe series as you dot need to fiddle around with anti-vibration mounts. All you do is screw the fan into place and connection up the cable.
In order to put the Noiseblocker Multiframe series to the test, I chose to test all of the fans provided as well as comparing them to some tough opposition – the Noctua NF-P12.
As with all fans, I disconnected all the fans in my case and then only hooked up the fan which was to be tested taking readings from both the CPU and system temperatures.
In order to collect the data I used Speedfan which uses the computer’s own diode and took values for both load and idle states. For idle, I simply left the computer for about half an hour without running any processes and then took the readings. However, for load I loaded two processes of CPU Burn-In to load the CPU to 100% again leaving it for 30 minutes before taking the readings.
In terms of noise, Verdis Reviews is not at the stage where it can afford expensive equipment, like any sort of noise measuring equipment, and so this aspect will be left to the trusty human ear.
Ambient temperature was 18 degrees and the CPU Cooler used was the Intel Stock (copper base version), all fans were set to high.
As you can see the performance of the fans is directly proportional to the airflow (In most instances) produced by the particular fan and this makes sense. The lowest temperatures seen are from the M12-S3HS and they are roughly on a par with the Noctua NF-P12, even beating it in some instances. This shows that if you’re looking for great performance, the Multiframe series are right up there giving great results. Similarly if you wish to have slightly lower performance, the fans are staggered to provide this.
This is the aspect that I was most pleased about. In terms of vibrations you can’t detect any – very impressive indeed. Of course, the higher airflow fans do product some noise but then by definition you can’t have high airflows and very low noise outputs so this is expected. However, the noise is really very low for the performance offered and the lower spinning fans (namely the M12-S1 and M12-S2) were virtually silent – only up close could I notice the sound.
The fans are quite expensive and cost roughly £15 per unit. It’s high end most definitely but then again the higher price tag does give brilliant performance with a fan for silent enthusiasts, overclockers and all those in the middle.
I’m really impressed with these fans; the series provides a fan for basically every user depending on what levels of noise and cooling you wish to achieve. The best performing fan rivals the best of the best and even beats the NF-P12 in some instances. The other end of the scale (M12-S1), whilst still proving very good performance, is virtually silent but then again the M12-S3HS (high-speed fan) which has the greatest airflow is still exceptionally quiet. They really are awesome.
The only downside I can think of is the price but for a product of this quality it’s worth it.
If you’re looking for new fans, whatever your needs, these are then fans for you.
- Great performance range
- All very quiet
- Good looking
- Structure Borne Sound Absorbers
Thanks go to Noiseblocker for providing the fans for review.
