Raijintek Themis Evo Pro & Tisis CPU Coolers Head-to-Head Review

Performance

Now we’re onto the stuff that really matters, as you can see from the specifications below the Tisis is right on par with the Gamerstorm Lucifer, holding our i5 3750K at just 20c above ambient under full load, but it’s being beaten out by the Themis Evo, which managed a slick 15c above ambient.

The Tisis features two large 140mm fans that are pretty powerful, as such they are a little louder than most, but not overly so, putting them along side most other 140mm fan setups lower down our chart. The Themis Evo also scored fairly average on the noise test, sitting alongside the Corsair H75 and the Cooler Master Nepton 140XL water coolers.

This is where things really start to turn heads, just look where that Tisis cooler is sitting, it’s right at the top of the chart, literally the coolest CPU cooler I’ve ever tested! It beat out the 240mm water cooling radiator from Enermax by 3 degrees and even offered up the lowest idle temperatures too at just 2c above ambient. This is a performance hammer blow and a big win for Raijintek.

The Themis Evo is no slouch either, kicking the but of the Cooler Master Nepton 140XL water cooler by a full 3c, putting it just 1c behind the Corsair H75 water cooler, which is freaking impressive to say the least given that it costs a fraction of its nearest rivals (in terms of performance).

Another win for Raijintek is that the Themis Evo is the fourth quietest CPU cooler in our overclocking tests, creeping in just behind the three be quiet! coolers which dominate the top of the chart, although it’s worth pointing out that the Themis Evo performed better than all three be quiet! coolers in our thermal benchmarks.

The Tisis didn’t fare quite as well, there was audible turbulence from the fans when overclocked, but if that’s the trade-off for such ice-cold performance, I don’t care and neither will most enthusiast overclockers. I discussed this issue with Raijintek and they did say my fans were a little noisier than they should be, having looks at reviews from other sites, they are on average around 2dBa quieter, and we’re going to attribute this to it being an especially warm day when we were testing.
