Deepcool Gamer Storm Assassin II Review

Test Results And Final Thoughts

The Assassin II comes within two degrees of the standard-bearer NH-D15 at full throttle, both in CPU and PWM temperature. Temperatures at the lower fan setting are a little worse, but that’s because the Assassin II was manually set to 50% while the NH-D15 uses Noctua’s greater-than-50% resistor wire.

A look at the fan RPMs shows that Noctua’s speed reduction is closer to 25%. We used those resistor wires while trusting that Noctua knew the “optimal RPM” for efficiency. Meanwhile, coolers that lack this feature suffer from the “non-optimized” 50% setting. Or do they?

While the Deepcool Assassin II starts out a little noisier than the NH-D15, it ends up much quieter at low speed because 50% is such a low setting. Perhaps a retest of the NH-D15 at 50% is also in-order?

Slightly warmer and slightly noisier at full speed, the Assassin II ends up around 5% behind the NH-D15 in cooling-to-noise ratio. We’re now treating the 50% test as a bonus measurement.

Price is closer to the point, as the Assassin II provides a few percent less full-throttle performance compared to the NH-D15 but costs over 10% less. That means it’s a 5% better value. As for the value at low fan speed, this measurement really points out the benefits of motherboard-based fan control.

Final Thoughts

Barely underperforming our top “big air” CPU cooler, Deepcool’s Gamer Storm Assassin II comes at a low-enough price to make it a far better value. That’s not to say it’s cheap, only that it’s cheaper than best cooler we’ve tested.

Some users will think it looks better too, and the extra 0.6” of space savings in both front-to-back and side-to-side dimensions will certainly help it fit more motherboard/case combinations. Yet better value alone is enough to earn it some kind of value award.

Unfortunately, my previous experience of mounting 3-pound coolers on 4-layer motherboards forces me to narrow my recommendation for this 50-ounce unit to stationary systems with six-layer boards. That’s still a broad enough field to cover most LGA 2011 and LGA 2011-v3 models, but it's far less than the range of products the Assassin II actually fits. If in doubt, I recommend asking a few users in our community forums.

    Designed to "concur"? Did you mean "conquer"?

    More heat-pipes than the Noctua and it still gets beat in cooling performance? The Noctua is a touch louder but thats no big deal. The D15 I have is plenty quiet.

    Why only 3 coolers to compare? Surely the Phanteks dual tower (with 140mm fans) would have been a great competitor here considering the price point is closer to the Deepcool cooler than the Noctua is.

    I have the original version on my 4790k build , they are incredible coolers , super sturdy fans.

    Its RPM is 270 lower, that probably explains most of the handicap.

    It might be interesting to compare these while using the same fans on both, to see how much the heatsink's structure affects performance. Even better would be a constant air flow rate test to take fans completely out of the equation.

    Original has the sturdiest fans I've come across.

    The 3 pound thing doesn't matter when you mount the motherboard horizontally. This thing fits fine in my Sentey ss6-240 case. I can overclock the AMD Athlon 2 x4 860k to 4.2GHz without hiccups.

    How many people still buy full-height horizontal desktop cases deep enough to fit a 212 these days? Nearly everyone uses towers and most popular "pizza box" type systems use either half-height expansion slots or angle risers to keep height down.

    Perhaps I left out "with" and meant to say it was agreeable to competing products?
    -Fixed, thanks :D

    Because the D14 and its Phanteks doppelganger were reviewed on the previous platform.

    You should contact News Man Niels and see if his friends at Cryorig would like to send one. Or maybe I should.

    You're both mostly right :)

    I own one Crashman, Fantastic cooler would be nice to see the big boy reviewed.

    The Noctua still wins out. Again.

    Agree with seeing a review of the Cryorig R1!

    I don't like coolers that the base plate doesn't have direct copper pipes touching the cpu, because it lowers the performance of cooling.

    So how does the "Deepcool Gamer Storm Assassin II" make my games faster?
    Or did the marketing division of the sirius cybernetics corporation just add "Gamer" to the name make people but it?

    Nope, most of the top coolers have flatter bases with encapsulated heat pipes. The primary benefits of direct-contact heat pipes are lower weight and lower cost.

    Lower temperatures assist overclocking.

    Well i do prefer lighter weight, like mine Hyper 212. I don't want my mobo bending and start breaking ic's

    If you like the Hyper 212 take a look at the Cyrorig H7 next time you're in the market for a heatsink. Slightly smaller and better cooling than the EVO for the same price.

    We had a System Builder Marathon article discussing several boards that failed after installing a big cooler, and I'm tired of linking it so I'm going to ask you to prove that it doesn't happen.
