Batting .500

  • Summary: 5 Eggs had both worked ok. I debated giving 4 eggs, knowing that I always get the one bad one in a bunch... The second one sounded like a teenager revving his engine at a stop light. The first one is nice and quiet at a fairly low speed, and is quieted than I would have expected at higher RPM's. The steel grill is nice for a fan mounted in the bottom of the case to help supply air. Make it just a touch harder for anything to drop into the blades.
  • Pros: Fan #1 - Quiet, moves air well, includes a steel grill. Comes with it's own speed controller.
  • Cons: Fan #2 - Continuously revs up and down. Could be either the fan itself or the speed controller, but I simply disconnected it rather than investigate it. A little difficult finding a good place to mount the speed controller.

I love these fans! (But they are a bit loud)

  • Summary: The fact that they include a trim-pot to dial down the RPM's and thus quiet the noise is a very thoughtful decision on the part of the manufacturer. These are now a first choice for me for 120mm case cooling fans or for any high CFM application. I've even rigged one of these up to cool my DSL modem for my internet connection. The modem tends to run hot. I just added an old power supply and jumpered the 24-pin connector with a bent paper-clip.
  • Pros: These are great case cooling fans at 100+ CFM, but they are a bit loud. They can be slowed down with a trim-pot to make them more quiet but that also reduces the CFM. All in all, a first choice for me from now on for 120mm case cooling fans. I've installed four of them on one case and will likely use another four to upgrade another case I have. Excellent fans.
  • Cons: Loud. Noisy. But that's to be expected at the high RPM you need in a 120mm fan to push out 100+ CFM. I'm used to it but not everyone can tolerate it.

Amazing CFM, loud

Robert A., Newegg
6 March 2014
  • Summary: I don't use the included fan controller that came with this fan. I use an aftermarket one I have installed in my case. At lower RPM these fans work well and similar to cheap case fans, quiet too. When doing intensive work, or BTC mining :D, rev these fans up and watch them scream! But they will cool even the hottest video cards.
  • Pros: Amazing fan, with excellent CFM. This fan can move air and cool a PC well! Inexpensive
  • Cons: Loud :D

Moves a lot of air

Stetson S., Newegg
28 January 2014
  • Summary: I bought this as an exhaust fan and it's just about perfect for that. I didn't have any slots for the fan controller, but since the cable is so long, I was able to break off the supports and secure it flat to my desk. The only real issue I've had with it is the noise it makes at high speeds. Granted, a large portion of that noise is air movement, but a definite coil whine can be heard. It's loud enough at max speed that I can hear it over what I'm watching on my headset.
  • Pros: Moves a ton of air. Cables are nice and long. Solid fan controller
  • Cons: No PWM (but I knew that ahead of time) Extremely loud at high speeds

It's okay...

  • Pros: Fans move lots of air. Comes with fan controller. Comes with fan grills.
  • Cons: I hate it that it has three wires coming out the fan. It messes up with my wire management, only if it had a 3 -4 pin like the other fans. Fan controller doesn't fit anywhere in my case. It's nice that silverstone supplies a fan controller, but i got no where to put it.

Great fan

Brian M., Newegg
25 October 2013
  • Pros: Fan controller is a plus Quiet all the time (and let's be honest this probably won't ever run at max rpm unless you need crazy cooling)
  • Cons: Erm it doesn't come in a pack of 10 for the price of one?
