Corsair H80 Stock Fan

When I met with Corsair, I asked them specifically which fans they would recommend using with the H80 since they had just released their new SP120 line. Surprisingly, they suggested that unless you're going for extreme silence, the stock fans that come with the H80 would provide the most balanced performance. Part of the reason for this is that the H80 has a built-in three speed fan controller that can change settings just by pressing a button on the waterblock; you can read more about it in our review of the H80 itself here.

Airflow (in CFM) Static Pressure (in mm/H2O) RPM Rated dBA
46-92 1.6-7.7 up to 1300 (Low), 2000 (Medium), 2500 (High) 22-39

Our own testing with the H80 on its own revealed a decent range of performance, with the Medium setting seeming to be the ideal one, but we'll be able to compare them to a broader range of fans this time to see if the H80's stock fan continues to be the best choice.

Corsair SP120 Quiet Edition and High Performance Edition

The "SP" in "SP120" stands for "Static Pressure"; Corsair recently released a series of fans geared for radiator and case use, with the SP line targeting radiators. The designs are fairly slick, with removable colored trim and rubber mounting posts to mitigate vibration noise. The Quiet Edition has its fan speed capped and is designed, as its nomenclature suggests, for quiet operation. Meanwhile, the High Performance Edition runs at a higher speed and produces more noise as a result.

37.85

1.29 1450 23
SP120 High Performance 62.74 3.1 2350 35

The rated performance of these fans is interesting, especially taking into account the SP120 Quiet's specifications actually being lower than the lowest setting of the H80's stock fan.

SilverStone Air Penetrator AP121

It's interesting to note that this fan has been the subject of a lot of debate on forums as to how fit it is for use as a radiator fan. SilverStone advertises a high static pressure for the AP121 and its grill is designed to direct air, suggesting that it would be a potentially ideal radiator fan. At the same time, its grill also potentially obstructs a decent amount of airflow.

35.36 1.71 1500 22.4

The AP121 isn't much for airflow, bested even by the quiet SP120, but it sure fires that air with a decent amount of force. This is going to be one to watch; it should be a strong performer due to its solid static pressure, but we'll see.

    Personally, I was surprised not to any Scythe fans. IMHO, they make the best fans of manufacturer. I've been buying Scythe exclusively for several years now with a focus on quiet computing, and IMHO, their dbA ratings are spot on whilst providing excellent cooling. Reply

    Sorry, but this review was very lackluster, and is void of explaining the most important factor that affects fan performance on a radiator, the fin density (Fins Per Inch). That H80 unit uses a very dense FPI setup (roughly 20), which will greatly affect the performance of a fan, and thus render your results totally meaningless to users of less dense radiators.

    That's not even commenting on the omission of Scythe Gentle Typhoon AP-14/15's, which no thorough radiator review would be without, as they are considered one of the best rad fans available.

    I have to ask the Anand review editorsf, was this just a marketing filler review?

    If you're concerned about a fan's performance when used in conjunction with a radiator or heat sync then you look at the fan's maximum static pressure.

    You don't review fans based on fin density.

    Should have tested COUGAR CF-V12HP Vortex Hydro-Dynamic-Bearing (Fluid) 300,000 Hours 12CM Silent Cooling Fan with Pulse Width Modulation. I purchased these to run on the Corsair H100. The temperature differences and noise reduction over stock have been orders of magnitude different. Reply

    can't Agree more !!!
    I've bought 5 of these baby COUGAR CF-V12HP w/PWM for my H100 + 1 exhaust on White Corsair 600T - Doing push/pull and the temps/noise is really great.

    Am using 5 as well...terrific performance! Very low temps and low noise! Using the USAdystopia method of mounting as seen on utube. Reply

    I have seen comparative fan tests before done by SPR.
    I have none PWM fans and I can control their speed using Speedfan. You telling me the Corsair cooler doesn't allow that? a fixed speed fan sucks.

    I would like to see this test of fans repeated and including more fans. test for how much air the fans move at different RPM's(600, 1100, 1800, Max rpm) and at what point is the air/noise useless because the temp won't go any lower and the db tradeoff. Now that is something i have been wanting to see for some time. Also include a breakdown of fan components and whether they matter. diff types of bearings and suck plus why should people care to have pwm and why isn't every motherboard i run into has only 1 pwm header.

    With most of Asus's Z77 motherboards having all PWM fan headers, that, I think, is the way the industry is going. I would like to see a similar shootout with PWM fans. Also, I would like some 140mm fans in there, as a lot of cases can mount 140mm fans these days.

    It is nice to see you do a fan review, though. I hope you will do some more!

    The nice part about the ASUS 7x boards is that they can handle any type of fan.

    Connect a 4-pin PWM fan, and it will be PWM controlled. Connect a 3-pin classic fan, and it will be voltage controlled. You can mix and match however you like, too. They've really done a great job on the fan control, an area that other manufacturers have sadly chosen to ignore for many years. Hopefully that will change in the future.

    The 7x boards do this? Because my Z68-based ASUS board has a load of fan headers and they're all PWM, it's utterly pointless right now. PWM fans are rare as hen's teeth, most of the popular ones are three-pin right now. Reply
