Deepcool’s newest compact AIO liquid cooler goes big on performance, but with an $80 price tag can it still manage to score the value win as well? To find out we’ve put it to the test against our top three compact air coolers.

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Test Method, Results And Analysis

We retain the hardware configuration from our previous (non-liquid) compact cooler reviews to maintain the consistency of the results.

Since this is the first compact liquid cooler that we’re testing with this testing rig, we don’t have any data from other compact liquid coolers to compare with the Captain 120EX. Instead, we will be putting it to the test against the previous three top performing compact air coolers.

CPU Cooler Comparison Products

For today’s tests the Captain 120EX will be going up against some stiff competition from our three best compact air coolers. We have little doubt that the Captain 120EX will able to outperform the competition, however considering that it comes to the fight with an $80 price tag, and considering the $45 average price tag of the other coolers, it’s going to be interesting to see if it can still pull off the value win.

Test Results

As always, the ambient temperature of the room was maintained at 26°C (78.8°F) and noise levels were recorded 0.25m from the case's front corner on the side that opens, and were corrected to the 1m industry standard by subtracting 12 decibels.

As expected the Captain 120EX outperforms all of the other coolers in our comparison set by a decent margin at both high and low fan speeds. Besides the use of liquid as the cooling medium, we also attribute the Captain 120EX’s success partly to the fact that the it jettisons its hot air out of the case, unlike the other coolers that dump their hot air back into the case to be recirculated. This ought to give it a bit of an advantage, since it almost guarantees a steady flow of cool air for the cooler to work with.

As we mentioned earlier, the new dual-blade fan included with the Captain 120EX allows it to maintain almost the same amount of static pressure as the previous model, while using a lower fan speed. For those keeping score, the fan speed for the older model’s fan was approximately 2200 RPM. The two products output a static pressure of approximately 3.31 mmH2O (Captain 120EX) and 3.71 mmH2O (Captain 120). Finally, the second tach speed listed above for the Captain 120EX is for the pump’s impeller speed, which remains constant at about 2200 RPM.

While the Captain 120EX isn’t exactly any quieter than any of the other coolers in the review, it is does keep the CPU cooler for the same amount of noise, which will give it a distinct advantage in the efficiency scores. And again for those keeping score, although we haven’t measured the model it replaces, Deepcool does advertise that the slower spinning fan on the Captain 120EX is about 8 dBA quieter.

As expected the Captain 120EX commands a bit of an advantage in our efficiency ratings, thanks to its cool temperatures and low noise levels, but is it enough to put it on top in the value measurement?

Unfortunately for the Captain 120EX its $80 price tag is enough to put it at the bottom of our list when compared to the performance and rock bottom price tags of the other coolers listed in the review. Considering that the Captain 120EX is still cheaper than a good lot of the 120mm liquid coolers, and even some of the air coolers on the market, we feel the value numbers above may not tell the whole story. Nonetheless, the lack of comparison data on competing liquid coolers coupled with a loss in the value charts, keeps the Captain 120EX from winning our unqualified recommendation at this time. However, it does still gain our seal of approval for anyone looking for a solid, high performance, compact liquid cooler.

    Maybe it is just the picture, but that looks like an awful lot of thermal paste on that cpu?

    Shame this wasn't a Captain 240EX review. It's right at the $80 price range itself (on sale though. Normal going price is $89 or sometimes $99).

    1. I just don't get the "from our three best compact air coolers" part. At $80, tne article would have been nmore valuable to the reader if it was compared with other air cooler in it's price range like the the NH-D15 ? Comparing with only cheaper offerings (Brontes $35, other two in low to mid $50s) seems almost designed specifically to show the 120X in a favorable light. Even if it sells at a lower price, seems the Phanteks, Thermalright, H7 and some Scythe coolers would have been more valuable to the reader.

    Granted this is a bit less than apples and apples comparison as the fan speeds differ but here we see ...

    http://www.eteknix.com/deepcool-captain-120ex-white-edition-cpu-cooler-review/4/

    Delta T w/ system overclocked and inder load:

    Noctua NH-D15 = 34C (42 dbA)
    Deepcool Captain 240X= 35C (43 dBA)
    Deepcool Captain 120X = 47C (43 dbA)
    Cryorig H7 = 44C (42 dbA)

    The "same price" air cooler beats the 120EX by an enormous 13C and does it quieter. Doubling the radiator and fans, it still can't catch the Noc in thermal or noise performance despite being $20 more. Even the $35 H7, at only 44% of the price tops the 120X in both thermals and noise. Now if ya triple the fans and use the 360 Gamer Storm Captain, it ties the Noc in thermal performance.

    The "Gamer Storm" Captain is slightly different from the plain Captain in that the "Storm" apparently refers to the air stream created by the higher rpm fans which jumps from 1800 rpm to 2200 rpm and therefore twice as loud.

    Techpowerup tested the 360mm version Of the Gamer Storm and with 3x the radiator, it tied the Noctua both hitting 83C max in the FPU test noting:

    "Using Aida 64 to put a high load on the CPU's FPU for as much heat as possible, the Captain 360 again performs poorly. At stock, it is rivaled by 120 mm AIOs and beaten by many high-end air coolers. "


    In short ... I like the article, found the aesthetics interesting tho too "blingy" for my tastes. But if this is truly going to sell at $80, it should be compared with other $80 coolers. If it eventually sells for less, than the $55 - $80 range having the better options available in that price range would have been more useful and relevant.


    2. "As expected the Captain 120EX outperforms all of the other coolers in our comparison set by a decent margin at both high and low fan speeds. Besides the use of liquid as the cooling medium, we also attribute the Captain 120EX’s success partly to the fact that the it jettisons its hot air out of the case, unlike the other coolers that dump their hot air back into the case to be recirculated. "

    Using our test bench (5 x 140mm of rad, push and push / pull capability, 6 thermal sensors, infrared thermometer, and fog machine for air flow tracking, we have not found this to 'hold up" in practice. Ever notice that every custom loop guide and most CLC manufacturers (i.e. Corsair) state that "for best cooling performance, we recommend that the fans be installed as intakes". But what do they know, they only make the things.

    http://www.corsair.com/~/media/corsair/download-files/manuals/49-000175_rev_ab_h100i_qsg_web.pdf

    Cooling performance is proportional to delta T ... example:

    Ambient Air = 23C
    Interior Case Air = 28C
    Coolant Temperature = 33C

    Using exterior cool ambient air therefore has twice the cooling effectiveness on the CPU than using interior case air.

    When peeps buy this cooler, what component are they concerned about lowering the temperature of ? Is it the SSD or HD ? Is it the MoBo ? What component inside the case will have its performance reduced because of this rad exhaust air being 3-5C above ambient ? ... assuming it every actually passes over those components. None. You buy the CPU cooler to cool the CPU.... using preheated case air instead of cooler ambient air reduces the effectiveness of this effort.

    The other factor not considered is that one of the biggest cooling features of your case is the rear grille. The typical case comes with 2 front fans and 1 rear fan. The two front fans can lose as much as a third of their air flow to inlet air filter resistance. ... more if left to get really dirty. So now we have 2 fans on the front blowing air in, reduced to 2/3 of their effectiveness (1.33 fans) and 2 fans blowing out.

    Now with more air blowing out than in, you are sucking in PSU (10-15% of PSU electrical consumption wasted as heat) and GFX card exhaust, which exited thru the rear of the case, right back into the case thru the vented slot covers and rear grille. So why are we worried about the waste heat from the cooler being tossed around the case, but no concern exists about the heat from 1 or more 250 watt GFX cards and PSU exhaust being sucked back in and bringing all that dust along with it ?

    Finally, if we look at the air path... with CLC fan blowing out (either thru top or rear) we have intake air drawn up to the top rear corner of the case ... and we have all the GFX card heat and recycled hot exhaust from PSU / GFX card all passing over the MoBo / CPU and preheating the air going up thru the radiator and exhaust fan, either of which is located on top and rear of case.

    When used as intakes.... locating the rad on top, all air from 3 fans is forced out the rear grille with positive case pressure and no exhaust (and dust) being sucked back into the case. GFX card exhaust (generated externally) stays outta the case, that which escapes the shroud and radiated inside the case is drawn upward and out of the case. Intake air from the rad is blown past the upper MoBo CPU area but how is this any worse the GFX card heat which will dot he same ?

    Of course the effectiveness of these techniques depends on having a case design matched to your installation and whether, at least with 120mm rad, its located on rear or top of case. No doubt you could create a scenario where there is an advantage here for the exhaust option ... however we gotta go back to this:

    "we also attribute the Captain 120EX’s success partly to the fact that the it jettisons its hot air out of the case, unlike the other coolers that dump their hot air back into the case to be recirculated"

    a) The Noc and H7 "dump their hot air back into the case" and yet the clearly beat the 120EX ... we therefore a) can't credit a "success" because it loses to both those coolers and

    b) On the cooler which exhausted the air, the CPU was hotter.

    When The Gamer Storm Captain EX 360 with 360mm of rad and fans, can't beat an air cooler's thermal performance ... and is twice as loud even in the 120mm version ... I can't see making a case for the 120mm, 240mm or versions.

    Yeah, its not competing against air coolers. I don't have a problem with the comparison per se, but you really need to test it against other all in one coolers as well.

    Its a given that liquid coolers are going to be more expensive than their air cooler counterparts, simply due to the extra components involved. So a value comparison is...well, less than useful. I mean, you don't need to test it to know that its not a great value compared to air coolers.

    Hopefully, as a new company, they've worked out their leak issues. I Purchased the Genome case for a client build and after a week it sprung a leak and ruined EVERYTHING. Total system loss. $2700 worth of gear up in smoke and sparks. Although I will mention they reimbursed my client for the loss which is brownie points to them.

    Yup, guys above are right. This article lacks love. It should have been compared to air coolers and AIO of the same price.
    The chosen competitor parts is justified for low height cooler but that's just about it.

    To quote the article in page one says :
    "Deepcool’s newest compact AIO liquid cooler goes big on performance"

    and page two says :
    "For today’s tests the Captain 120EX will be going up against some stiff competition from our three best compact air coolers."

    So the key word is COMPACT, so the article does not compare coolers in the same price range but compare coolers in the same type, which is COMPACT type, which intended to put inAIO cases that usually has small foot print so the Noctua NH-D15 will not fit.

    That position is one way to look at it, except for the fact that a) the Noctua NH-L12 at 150mm tall can hardly be called "compact" b) comparably priced and "more compact" air coolers were ignored and c) the top air coolers generally run from 150 to 165mm.... less than 10% taller than the one on the review.

    The NH-C14S is compact, shorter than the included NH-L12 and beats the Deepcool Captain 120EX in the above linked test and costs less. Would think that how it would hold up in a performance / noise test versus the Deepcool Gamer Storm Captain 120EX.

    Bet the Phanteks and Cryorig compact coolers would also do fine in this comparison, I wasn't ambitious enough to try and compare all of them, I don't get paid for this kind of research :).

    However, in the TPU graphic even the $25 Hyper 212 loses by only 5C to the Gamer Storm with 3 times the radiator and there are certainly compact coolers that do much better than the 212. The Dark Rock 3 beat the Gamer Storm by 4C... and here the Cryorig C1 (only 71 mm tall) compact cooler topped the Dark Rock 3

    http://www.tweaktown.com/reviews/7034/cryorig-c1-cpu-cooler-review/index6.html

    And here we have the The Dark Rock TF just 1C behind the NH-D15 ... the Gamer Storm 360 with 3 times the radiator also finished 1C behind the D15. So that puts the Dark Rock TF equal to the Gamer Storm Captain 360 w/ 3 x 120mm radiator ... it also costs the same as the Gamer Storm Captain Ex120. It's a low profile cooler but wont fit in every ITX case I imagine but will fit in more cases than the Noctua NH-L12 so "compact" does not seem to be the defining criteria for exclusion. It's 131mm tall, significantly less than the 150mm Noctua NH-L12 which was included.

    http://www.guru3d.com/articles_pages/be_quiet_dark_rock_tf_review,8.html

    But also remember that even 120mm CLCs often cause fit issues ... did a user build where the user selected a 120mm radiator CLC from Antec. Problem was, with the rear case mount, the rad interfered with putting the 1st GFX card in the top PCI-E slot. The case came with pre-installed top of case fans and trying to put it there a) made you lose two case fans and b) the fans were pre-wired to switches on back of case so moving was not an option

    Of course, proper case selection comes into play here, bit all cases are so limited and selecting small compact cases does not necessarily gimp cooler selection. I helped a user here yesterday whose case had capability for just two fans ... a 120mm and an 80mm.

    Here's 3 popular ITX Choices, 2 of which will fit almost any cooler:

    Corsair 250D - 0.99 cu.ft. / 95mm cooler clearance / fits 240mm + 140mm rad / fits (2) 120mm, (1) 80 and (1) 140mm fans / 290mm GFX clearance

    Bitfenix Progidy - 1.28 cu.ft. / not listed but fits 160mm cooler w/ in excess of 25mm above in install video / fits 120mm rad / fits (4) 120mm fans / 320+mm GFX clearance

    Enthoo Evolv - 1.20 cu.ft. / 922mm cooler clearance / fits 5 x 120mm of rad or 3 x 140Mm + 2 x 120mm / fits (5) 120 or 140mm fans / 330mm GFX clearance

    The one case that wouldn't ... also won't fit the Noctua NH-L12 used for comparison in the review.

    Given the above, I have to say no ... to turn a phrase:

    The key word is clearly not COMPACT ... the article includes cooler that are 150mm tall and excludes many coolers in the same price range that are shorter and more compact.

    It also shows that while some cases won't fit some of the leading low profile coolers, those cases also won't fit the chosen Noctua NH-L12 "compact cooler" used in the review. And also many small footprint cases will fit some of the best performing standard coolers, even the NH-D15. It's a matter of case design... the Bitfenix Progidy misses fitting the NH-D15 by 5mm but the **smaller** Enthoo Evolv does. And the Prodigy does fit the NH-D14 and even the Cryorig Ultimate if ya skooch the fans down 3mm
