Top notch quality

Daniel M., Newegg
9 April 2015
  • Pros: I can't believe how long these fans last. Cranking lots of air since 10/14/2006. WOW! I have bought other fans that didn't last a year that start clicking and clacking that cost $9.00 You get what you pay for. Expensive, but they last over a decade...
  • Cons: Can be a bit loud, but that is because it is pushing LOTS of air. Just get a fan controller. Recommend getting "NZXT SEN-MIX2 Sentry Mix 2 Fan Controller"

  • Pros: Works well, moves air, fairly quiet. Workmanship is nice and won't be an eyesore if you've got a big window.

Over a year later ...

Paul M., Newegg
27 December 2014
  • Pros: I bought 2 Silverstone FM121 120mm case fans over a year ago from New Egg. I spent the extra dollars because I was hoping to re-use the case fans in future builds. When I attempted to re-use the fans I ran into a fragility around the attachment of the variable control wire to the fan. Over the co...
  • Cons: The wire connecting the variable control interface to the fan is a point of failure to be aware of.

  • Summary: Not adding this as a con since the fans work very well and I have been completely pleased with them but the 3 pin header they come with for power aren't really a great option. You're supposed to plug them into the fan controllers that come with them but if you don't want to use the included the fan...
  • Pros: They work extremely well. I bought them to replace the two fans that came with the Corsair H75 liquid cooler because those stock ones weren't cutting it. It's been a few months now so I don't remember the exact decrease in temperature these fans produced but I want to say it was in the neighborho...

Off the rails in one year

Gita K., Newegg
14 September 2014
  • Pros: The manual adjustment made it possible to extend the life of a graphics card that was getting on in years by kicking up the cooling when needed.
  • Cons: After a year of operation, the fan is getting very noisy. I have adjust the speed often in order to get it out of a wobbling pattern that is very noisy. I will have to replace it again.

Batting .500

Joseph P., Newegg
17 August 2014
  • 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.
  • 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)

Harry S., Newegg
2 August 2014
  • 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.
  • 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...
  • 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.

Silverstone 110cfm fans

David S., Newegg
25 June 2014
  • Summary: I use my original 2 fans on an old Cooler Master CPU cooler that takes 2 120-mm fans on an old LGA775 QX6700 quad extreme, that happily runs at 12x or about 3.2ghz, at a happy ~60C under full heavy load. The speed sensor wires are plugged into the cpu fan sockets. Usually pretty quiet that way?
  • Pros: I LOVE these fans! Bought my first pair from Newegg over 5 years ago, still running like new. They really do move some air!
  • Cons: At full speed, they are loud!
