The SilverStone FN81 80mm black case fan provides essential cooling for today's desktop computers. The fan spins at 2,050rpm and creates 23.5dBA providing efficient cooling with little additional noise and its standard design can be used to pull cool air into your system or push hot air out.

The fan connects to your motherboard's standard 3-pin fan connector for power and the included dampening pads help soften fan noise and keep vibrations caused by other computer components from effecting the fan's operation. This is an excellent value in case cooling!

  • newegg Extra Quiet The extremely-efficient SILVERSTONE FN81 works at a whisper-quiet 23.5dBA at 2,050 RPM.
  • newegg Built-in Vibration Dampening Pads The included vibration dampening keep noise to a minimum during fan operation.

5 out of 5 eggs

Pros: Pretty quiet for an 80mm fan. Appears to be well-made.

Cons: Doesn't move a ton of air, but it's plenty given the low noise level.

Other Thoughts: Probably not quiet enough for a silent build, but it's quieter than average.

2 out of 5 eggsMeh

Pros: moves air

Cons: noisy, annoying vibration.
I expected quality from Silverstone, didn't get it.

Other Thoughts: better use the silicone mounts cause you will need them to damper the rattle from this noisemaker.

5 out of 5 eggsVery silent.

Pros: I have a silverstone case GD05, and I have the 120mm version of those, I recently install 2 80mm to help with cooling and they are great for the money, no huge CFM but very silent.

Cons: none

5 out of 5 eggsIt's a fan............

Pros: Inexpensive, Very quiet. Seems like a fan that is built to last years.

Cons: Low CFM/RPM's...........

Other Thoughts: I don't know how this fan can move air inside a case.....Doesn't seem like 2000 rpm is fast enough to do the job (My opinion). Seems to be a very nicely built fan.

4 out of 5 eggsDecent product

Pros: This is another quality product from Silverstone, if you don't know yet, Silverstone has many other great products.
This 80mm fan moves moderate to decent airflow.

Cons: I suspect that the CFM rating to be inflated, this fan seems to move ample air and that's about it.

Other Thoughts: There are better 80mm fans than this(if cooling is what you're looking for!)

3 out of 5 eggsFine fan and moves air but noisy

Pros: Moves lots of air and a cheap price. Would be good if you don't mind hearing your fans running.

Cons: Too noisy for me. Makes a jet engine noise when running and it spins at 2200 rpm not the 2050 as stated.

Other Thoughts: I have had silverstone fans before and they are whisper quiet but not this fan. Too noisy for my quiet build. I can't hear my four other fans but can hear this one no problem. Moves air though but at a price.

Manufacturer Response:

Thank you very much for purchasing a SilverStone. Please note that fan speed is rated at plus or minus 10% range and we rated the FN81 at 2050rpm +/-10% so 2200rpm is within the range of specification.
