The Rosewill ROCF-11003 is built to perform with a super silent 14cm fan which uses S-FLOW blades supplying 30% more airflow than a standard fan at the same speed. The greater performance combined with PWM automatic speed control allows the fan noise to be kept to a minimum.

  • newegg Decent Cooling Performance The super silent 14cm fan with S-FLOW blades delivers a maximum air flow of up to 89.55 CFM and static air pressure of 2.76 mm H2O for decent cooling performance.
  • newegg Long life expectancy and Low noise HDB (HYDRO-Dynamic Bearing) provides up to 50,000 hours lifespan and low noise level. Thanks to PWM automatic speed control, the noise level is kept at 12.5 -22.19 dB(A).

3 out of 5 eggsNot bad, not great either

Pros: Good CFM and static pressure
Fairly quiet but makes a weird sound (see other thoughts)

Cons: The mounting pieces that come with it are garbage, they're flimsy pieces of rubber that rip quickly and don't do much of any good.
Has a weird sound it gives off that I've never heard from a fan before (probably from the bent blades).

Other Thoughts: I got this as an intake fan with a silverstone ultra thin fan filter. The static pressure from this work fantastic with the filter and has put my case into a positive air pressure inside the case (less dust and more fresh air getting into the case, so lower temps overall).

The fan itself makes the weirdest sound that I can't identify the cause of nor explain the noise itself. To say the least it's worrisome, and isn't noticeable from more than a few feet away. I only noticed it after installing (with the side panel off) and after putting my head up close to the case to examine that it was working correctly. The noise doesn't get worse as the RPM gets higher; it in fact gets drowned out by the sound of the air pushing through the fan, which is significantly loud. Despite the specs saying it goes up to 1300 RPM, my case manages to get it up to near 2000 RPM which gets loud but not unbearable. I'm not sure if pushing past the rated 1300 RPM is safe, so I don't recommend it.

5 out of 5 eggsExcellent case fan!

Pros: Very quiet fan with strong air-movement. If your not into LED displays, then this is the 140mm fan for You. It move air like the ol' Cooler Master 120mm with bent-blades. Bent-blade fans have good static pressure for heatsinks and radiators.

Cons: No LEDs.

Other Thoughts: Makes an execellent case fan! Very quiet throughout all speeds.

5 out of 5 eggsGreat case fan

Pros: Quiet
Relatively inexpensive

Cons: none

Other Thoughts: Replaced a top mounted fan in my Antec 300 case that was beginning to make annoying clicking noises. Connected via the 4 pin motherboard header, so it's PWM controlled, which helps keep it quiet. The 'silent' moniker is a bit misleading. It is quiet, but it's moving air which causes noise. I have to concentrate to hear it, however.

5 out of 5 eggsFantastic Air Mover!!

Pros: -Moves a huge amount of air, almost 90 cfm!

-Actually not very loud at all

-Pretty decent static pressure

Cons: Maybe a little expensive? But, these are quality, and you get what you pay for.

Other Thoughts: I bought one to place in the bottom from fan mount on my Fractal Define R4, since their gans only do 66 cfm. I wanted to increase the amoun of air going in, but not at a huge noise expense. This thing fits the bill. Together with the Fractal fan in front I have enough fresh air making it past the drive cage into the case, for only a slight increase in noise. I am highly impressed with this Rosewill fan!

2 out of 5 eggsQuiet my foot...

Pros: PWM. Lots of air movement

Cons: Blatant false advertising of the sound levels. I believe that due to the shape of the blades there is more noise than more traditional shape fans. It spits out a lot of air to the sides but spits out a lot of noise. I have to lower the RPMs down to 600ish to not hear it whilst sitting at my computer about 6 feet away but still, when I compare it with my ear up close to my Lian Li 140mm fan running at the same RPM, the Rosewill still has a distinct sound characteristic that is louder than the Lian Li fan. It's just a loud buzzing, airplane sound and I don't like it... so this means I will never run this fan over 600ish rpm. However I can raise my Lian Li fan up to 1000rpm and I don't have that annoying airplane sound. At least the airflow is good so you can run it at lower RPM at it's still somewhat effective. But there is no way I'd run this at a higher RPM even when gaming with headphones... it's that loud.

Not only that but this fan makes a ticking sound that the Lian Li fan doesn't make.

Other Thoughts: Shame on Rosewill for lying about their fan's noise levels. I'm just calling it like it is. You can see other reviewers saying the same thing, that there is no way this is around sub 20 decibels.

5 out of 5 eggsFan: it blows or pushes the air.

Pros: Beautiful fan, got two at the same time and have worked, silently for over two years now. Solid construction and attractive too.

Cons: I haven't found any issues

Other Thoughts: Some nicely placed leds would be a thought.

4 out of 5 eggsMore quiet than stock but not the best performance

Pros: Quiet, especially at low RPM's it was near dead silent. PWM control really helps to fine tune the RPM curve for ultimate control.

Cons: Not really a con per say but I was expecting this fan to perform better than the stock fans that came with my H110, but at similar RPMs they pretty much performed the same.

Other Thoughts: I tested these fans on my H110 vs the stock fans that came with it. The fans are setup as intakes at the top of my C70 case in a push configuration. I used Easy Tune 6 to control the PWM for the fans (CPU fan header has a Y-splitter to control both fans at the same speed). I started at 10% and went up 10% until I max'd out the RPM's. I tested these all at idle on a i7-3770k @ 4.5Ghz. I was mainly testing for how quiet they were and in that regard they are much better than the stock fans. At idle the CPU temp really wasn't any different between the two, except that when these fans are @ 10% PWM it runs at 650 RPM which saw temps rise by a couple degrees, but at similar RPMs the temp was the same. I know I probably should have run tests at full load as well but like I said I was mainly testing for noise. I did run a little test at full load only on these new fans and based on previous tests with the old stock fans the results were pretty much comparable.
Final thoughts....great fans if you don't want to hear anything when sitting at idle and even at full load they are quieter than the stock H110 fans. But if you are look for top end performance you'll want a fan that can run at higher RPMs like Noctua's industrial series, but that also comes with a bigger price tag

5 out of 5 eggsFan of Fans

Pros: They work great move a lot of air system stays very cool.

Cons: none to report

Other Thoughts: Make sure your motherboard has the correct pins to connect to any fan you purchase. Fan power adapters mainly come in 3-4 pin adapters.

5 out of 5 eggs

Pros: Quiet at the right RPM

Cons: Louder at higher RPM

Other Thoughts: Depending on the motherboard, they may have some quirkyness on driving these PWM fans. I had to limit the 140mm PWM duty cycle to be far less than what the Mobo was driving which was trivial in the bios setting otherwise the fan was way too loud at 1.2k rpm it was defaulting to. It's good enough at 840rpm.
