Titan Fenrir Siberia Edition CPU Cooler Review

Today we are taking a look at the Titan Fenrir Siberia Edition CPU cooler which has both horizontal and vertical heatsinks. As such there is clearly plenty of potential for extracting heat from the CPU, just like having two radiators in one room of your house it will greatly improve the heating effect.
There are many CPU coolers on the market, and it is very hard to distinguish between them today. The vast majority have a single large heatsink connected to a copper block by a varying number and thickness of heatpipes and they also then have one or two fans depending on how expensive the model is. There are however a few manufacturers that have ventured into the dual heatsink arena.
Titan have a plethora of CPU coolers available on the market, many of which are based around a dual configuration … the vertical heatsink or the horizontal heatsink.  However, when you start adding fans to this set-up, things get a bit more complicated.
You still need to have decent airflow going through both radiators, with as little turbulence as possible, and preferably forcing the heat towards a case exhaust fan.

The box is certainly ready to rock, and has lots of distinct colouring with a huge blue swirl behind the product. The front of the box tells you the main features, the first being that it has ’5 x 8mm Heat Pipes’ which is quite impressive.
The other sides of the box continue a simple white theme, and this side shows you the potential thermal performance of this cooler when compared with a stock Intel cooler.
The opposite side of the box shows us the airflow of the CPU cooler and how this will help cool your other key components.
The back of the box lists the key features in a further 8 languages, as well as the specifications in the bottom right-hand corner.
Opening up the box we find that there are two fans included, one a 120mm fan, and the other a rather large 140mm fan.
Also included was a very simple installation guide for common Intel and AMD sockets, although some of the diagrams were not as clear as they could be.
The heatsink itself is certainly very different to your standard air CPU cooler, and has 5*8mm copper pipes as well as two quite large heatsinks perpendicular to each other. While it is a bit of a beast, it should still fit into most cases, although we expect it might be quite tight once the two fans have been fitted.
Both heatsinks have been made up of very dense aluminium fins, and the 5 thick heat pipes are equally spread out through the heatsink. This allows a lot of heat to be transferred to the very tips of the fins and hopefully with the aid of the fans should allow good thermal performance.
The Titan Fenrir Siberia Edition CPU Cooler comes with a lot of accessories, allowing you to install this CPU cooler on Intel LGA 1366/1156/1155/775 as well as AMD AM2/AM2+/AM3/FM1 sockets. There is also a dual-fan cable allowing you plug both fans directly into the CPU fan socket on your motherboard.
Firstly, before installing this CPU cooler, we removed our test system Akasa Venom Voodoo CPU cooler and backplate, and then removed our CPU to thoroughly clean any old thermal paste off. As you can probably tell this is an AM3 motherboard, and as such we will be showing you the AMD installation.
Firstly, we install the backplate, which as you can see does both Intel and AMD sockets in one go. We are using the ‘inner-most’ arms for the AMD set-up.
Once the backplate has been installed you can then screw on some thumbscrews to hold this in place. These also act as a spacer for the rest of the cooler.
We then take the standard retention bracket for the CPU cooler, which is used for both AMD and Intel Sockets.
Unfortunately, for an AMD installation we have to add on an extra bracket on each side, which meant using some very small and fiddly screws.
We were then able to install the heatsink, and screw in place with the thumbscrews. Unfortunately, there is very little access to the top of the thumbscrews and so it is very hard to use a screw-driver. We also installed one of the fans using the clips provided.
We then installed the motherboard and Titan Fenrir Siberia Edition CPU Cooler into the case, as you can see on the right hand side there is very little space and so you certainly couldn’t use the exhaust fan that you would normally find at the back of these cases.
We were also unable to get at two screws on the top of the motherboard, and you might say we should have installed the motherboard first (without the CPU cooler) but we did try this and found that we could not get at the top two thumbscrews of the CPU cooler. A logistical nightmare!
Finally, we could install the rather large 140mm fan to the top of the heatsink. This CPU Cooler while huge, does look quite good, although nearly hides our mATX board from sight.
Today we are going to test the Titan Fenrir Siberia Edition CPU Cooler with the AMD Phenom II X4 965 Black Edition CPU.  We recently tested another cooler from Akasa which we will use as a comparison during testing.  Each cooler tested today will be using its stock configuration of two fans, although of course the Titan CPU cooler has 1*120mm and a 1*140mm giving it the slight advantage.
We like to try and mirror ‘realistic’ conditions when possible, so instead of the ‘open bench concept’, we are mounting our test system inside the Cougar Solution case that we recently reviewed and as it didn’t have brilliant thermal performance this will help to identify any strengths or weaknesses of the two coolers.
Room ambient temperatures were maintained at a steady 18c throughout testing.

Digital Sound Level Noise Decibel Meter Style 2
We firstly ran some initial testing to get some idea of the potential of this cooler.
A lead of 3 degrees under load is fairly significant and this shows signs of some fairly impressive performance from the Titan Fenrir Siberia Edition CPU Cooler.
One of the features the Titan coolers boasts, is that it cools the surrounding components. As such, we ran tests specifically looking for improvements in other areas. We also tested over a much longer period of time to allow the temperatures of all components to rise, then settle.
As you can see from these results there were significant improvements to the thermal performance when using the Titan Fenrir CPU cooler … and not just in regards to processor temperatures.
The motherboard temperature was four degrees lower after the same time period. This is because the Titan Fenrir cooler is pushing a high level of cool air across the motherboard components.
The GPU is not directly cooled by the Titan Fenrir cooler, however the case ambient temperatures are almost 4 degrees lower which subsequently reduces graphics card temperatures slightly.
Today to test this cooler we have set our Digital Sound Level Noise Decibel Meter Style 2 one meter away from our case. The room rates as 22dBa before powering on the system.
We then removed the discrete graphics card, and temporarily turned all other case fans off. This leaves us with only the CPU cooler fans and very little noise from the power supply fan.
As this can be a little confusing for people, here are various dBa ratings in with real world situations to help describe the various levels.
KitGuru noise guide
10dBA - Normal Breathing/Rustling Leaves
20-25dBA – Whisper
30dBA – High Quality Computer fan
40dBA – A Bubbling Brook, or a Refrigerator
50dBA - Normal Conversation
60dBA - Laughter
70dBA - Vacuum Cleaner or Hairdryer
80dBA - City Traffic or a Garbage Disposal
90dBA - Motorcycle or Lawnmower
100dBA - MP3 player at maximum output
110dBA - Orchestra
120dBA - Front row rock concert/Jet Engine
130dBA - Threshold of Pain
140dBA - Military Jet takeoff/Gunshot (close range)
160dBA - Instant Perforation of eardrum
We then tested the acoustical performance of both the Akasa Venom Voodoo and the Titan Fenrir Siberia Edition CPU cooler, with both coolers running at their full speed.
The Titan seems to emit a little more noise as the 120mm fan spins up to 2,200 rpm. Thermal performance is better however.
The Titan Fenrir Siberia Edition CPU cooler is certainly an innovative design and it is refreshing to see a company try something different.
Unfortunately, it did take quite a while for us to install and we had to remove the motherboard and complete the procedure outside the case. The physical size of this cooler is likely to cause a few problems … it should in theory fit into most Mid-sized cases, but it will be very tight and you are likely to curse frequently during the installation phase.
As such I wouldn’t recommend installing this cooler into a small case, aim for a larger chassis design such as the CM 690 II or the Cougar Evolution for instance.
The cooling capabilities are quite impressive and the airflow methodology ensures that other component temperatures drop a little, which is certainly a good thing.
The acoustical performance is not as good as we were expecting as it is slightly louder at full speed than the Akasa Venom. I suspect this is due to the airflow arrangement as you are pulling in air through the top heatsink and then pushing the hotter air through another heatsink perpendicular to the first. This is clearly going to cause turbulence and increased  noise emissions.
That said, due to the decent thermal performance you could run the Titan fans at slower speeds while maintaining low noise levels. Unfortunately, when compared directly against high end coolers such as the Noctua NH D14, the Fenrir Siberia is lacking.
The Titan Fenrir Siberia retails at £62 inc vat and as such goes head to head against the Noctua NH D14, which is a significantly better cooling solution. It is quieter too.
We can’t give the Titan Fenrir Siberia Edition an award today. The cooling performance is quite good, but it is outclassed by competing solutions. It is also quite loud, unless you are willing to compromise by reducing the fan speeds and subsequently dealing with increased temperatures.
There is no doubt it is an interesting design and we appreciate that the airflow can help support surrounding components. At the end of the day however it just isn’t good enough to compete in the £60+ sector.
  • Decent thermal performance.
  • Cools other components not just CPU.
  • Rather large and not suitable for all cases.
  • Fiddly to install.
  • Outperformed by competing solutions at this price.
  • Loud at full speed.
