Titan Fenrir Siberia Edition CPU Cooler Review
By Rafael Otto Coelho on March 29, 2012


Introduction

The Titan Fenrir Siberia Edition is a huge CPU cooler with one horizontal heatsink with a 140 mm fan and a second heatsink equipped with a 120 mm fan. Let’s test it.

The Siberia (let’s just call it “Siberia” from now on) comes in a big cardboard box, as shown in Figure 1.

Figure 2 shows the contents of the box: heatsink, fans, a syringe of thermal compound, manual, and installation hardware. There is also a Y harness, which allows you to connect both fans on a single motherboard fan connector.

This cooler is discussed in detail in the following pages.

Figure 4 illustrates the side of the heatsink. Here you can see the shape of the heatpipes.

In Figure 6, you can see the tower heatsink side. The five heatpipes are distributed inside the heatsink.

The base of the cooler is seen in Figure 9. It is made of pure copper and looks nicely polished.

Figure 10 shows the “Kukri” fans that come with the Siberia. As we mentioned before, the Siberia uses one 120 mm fan and one 140 mm fan. Both fans are PWM-compatible.

Installation

So far, so good. The Titan Siberia looks like an awesome CPU cooler. Then we installed it on our testbed computer  (as you see in Figures 12 and 13) with the backplate on the solder side of the motherboard and thumbscrews (and plastic washers) on the component side.

We finished installing the cooler and powered up the computer. A few seconds later, the computer just powered off itself, along with the unpleasant smell of burned circuitry.

We checked the computer and, after some tests, concluded that the motherboard was dead. The reason was the poorly insulated backplate from the Titan, as you can see in Figure 14. This backplate is too big, and the black plastic insulators are too small, leaving the edges of the backplate uncovered. Unfortunately, we didn’t notice that the backplate was touching a small SMD component on the solder side of the motherboard.

As a result of that incorrectly designed piece, we had to buy a new motherboard and build a new computer for testing coolers and, since it is impossible to compare temperature results taken on two different setups, we had to reset our comparative chart. We retested some coolers, but it was impossible to retest all the models we already reviewed. Since we had to replace the motherboard, we decided to update our testbed. Its configuration is described in the next section of this review.

For testing the Siberia cooler on our new computer, we glued some insulating tape on the backplate before installing it. We also had to rotate it 90 degrees from its correct position, because it was still pressing some SMD components.

Figure 15 shows the Siberia installed on our new testing computer.

How We Tested

We tested the cooler with a Core i5-2500K CPU (quad-core, 3.3 GHz), which is a socket LGA1155 processor with a 95 W TDP (Thermal Design Power). In order to get higher thermal dissipation, we overclocked it to 4.0 GHz (100 MHz base clock and x40 multiplier), with 1.3 V core voltage (Vcore). This CPU was able to reach 4.8 GHz with its default core voltage, but at this setting, the processor enters thermal throttling when using mainstream coolers, reducing the clock and thus the thermal dissipation. This could interfere with the temperature readings, so we chose to maintain a moderate overclocking.

We measured noise and temperature with the CPU under full load. In order to get 100% CPU usage in all cores, we ran Prime 95 25.11 with the “In-place Large FFTs” option. (In this version, the software uses all available threads.)

We compared the tested cooler to other coolers we already tested. Note that the results cannot be compared to measures taken on a different hardware configuration, so we retested some “old” coolers with this new methodology. This means you can find different values in older reviews than the values you will read on the next page. Every cooler was tested with the thermal compound that comes with it.

Room temperature measurements were taken with a digital thermometer. The core temperature was read with the SpeedFan program (available from the CPU thermal sensors), using an arithmetic average of the core temperature readings.

During the tests, the panels of the computer case were closed. The front and rear case fans were spinning at minimum speed in order to simulate the “normal” cooler use on a well-ventilated case. We assume that is the common setup used by a cooling enthusiast or overclocker.

The sound pressure level (SPL) was measured with a digital noise meter, with its sensor placed near the top opening of the case. This measurement is only for comparison purposes, because a precise SPL measurement needs to be made inside an acoustically insulated room with no other noise sources, which is not the case here.

Error Margin

We adopted a 2°C error margin, meaning temperature differences below 2°C are considered irrelevant.

Our Tests

The table below presents the results of our measurements. We repeated the same test on all coolers listed below. Each measurement was taken with the CPU at full load. In the models with a fan supporting PWM, the motherboard controlled the fan speed according to core load and temperature. On coolers with an integrated fan controller, the fan was set at the full speed.

In the graph below, at full load you can see how many degrees Celsius hotter the CPU core is than the air outside the case. The lower this difference, the better is the performance of the cooler.

Conclusions

The Titan Fenrir Siberia Edition is a good cooler, except for the terrible backplate that is a real danger to any computer. This backplate simply fried our old motherboard, forcing us to build a new computer for testing CPU coolers. This happened because Titan engineers didn’t take a little care in projecting better insulating for the product backplate. It seems like they ignored the fact that most motherboards have some SMD component on their solder side.

Except for the terrible backplate, the Siberia is a good cooler, with good cooling performance and a nice noise level. But we have no way to give an award for a product that cost us so much.
