Titan Fenrir Siberia review

Performance Analysis

Unfortunately, the Siberia's unique design didn't pay off in most of our benchmarks. Its first set of disappointing results came in our LGA 1155 test rig: its idle Delta T result of 9°C is poor; just 1°C below that of a stock Intel cooler.

The Siberia wasn't impressive when our LGA 1155 system was run at peak load, either. Its Delta T of 51°C was better than the 73°C scored by the Intel stock heatsink, but worse than any third-party cooler: its nearest competition, the Thermolab Trinity, returned a Delta T of 49°C when running in its low speed mode.

Predictably, the Siberia also faltered in our more demanding LGA 2011 test rig. Its Delta T when idle of 9°C is good, but this fell to a mediocre Delta T of 62°C when running at its peak levels. That's the same level as the Be Quiet Dark Rock Pro, but worse than most rival coolers - the Thermaltake Frio Advanced, for instance, had a Delta T of 53°C in the same test.

The sheer size of the Siberia and its two fans do mean, at least, that neither spins particularly quickly fast and, as such, that noise isn't an issue. When installed into the LGA 1155 system little sound was noticeable from the Siberia and, while this increased slightly when we used the LGA 2011, it's certainly nothing to worry about.

Conclusion

It's the sheer size of the Siberia that works against it. There's simply too far for the heat to travel and, while it works on paper, in practice it's an inefficient and overcomplicated design when compared to traditional, compact coolers that simply work more effectively.

It’s best when it comes to our more demanding LGA 2011 test setup, with extra kudos won thanks to its ability to also keep the chipset's toasty VRMs chilled. Even then, other coolers make more sense: the Arctic Freezer i30 is a marginally better performer for half the price, and the Thermaltake Frio Advanced is much cooler and costs around £20 less.

Installation is tricky, too, and the bulk and design of the Siberia also make it an unwise option for those with particular types of motherboard or those who aren't using a full-size tower case. It’s best as a cooler for more powerful systems but, even then, rivals are cooler, cheaper and more manageable, and it’s coolers such as the Thermaltake Frio Advanced or liquid coolers such as the Corsair H80 or Antec Kühler H2O 920 that we’d still prefer for high-end rigs.
