5 out of 5 eggsGreat quiet little fan

Pros: Used these to replace the screaming 40mm fan in the power supply in my hadron hydro case. I placed two of them in a push/pull configuration. One in the factory location and another zip tied to the other end of the power supply. I plan to do the same for a noisy 1U server power supply I have in my basement office.

Cons: Not a lot of airflow. But that's physics. Moving air through a small space, i.e. 40mm, is noisy. You have to pick airflow or noise at this size.

4 out of 5 eggsSuch a nice little fan...

Pros: Another Cisco Catalyst 2950 install. As mentioned in another thread YOU MUST SWAP RED AND BLACK! The fan puts out -12VDC and fans run on positive voltage. Very, VERY quiet.

Cons: Although it flows a decent 5.5 CFM, it is only at 0.08inH2O. The stock fan was 8.5 CFM at 0.303inH2O. As long as the sides of the switch stay open it shouldn't be an issue.

Other Thoughts: When comparing fans of the same size you can have quite OR you can have high flow. In my case I probably could have done without a fan, but I wanted to put one in as a "just in case".

REMEMBER: SWAP RED AND BLACK LEADS IF INSTALLING IN A CISCO 2950 SWITCH! If you don't you risk letting the smoke out. Electronics run on smoke, and if you let it out they stop :)

4 out of 5 eggsDell P.C. 2724 Replacment

Pros: The stock fan in my 2724 switch decided it wasn't getting enough attention and was beginning to drive the office to the brink of insanity.

I ordered this fan because of its advertised low dBa and decent speed compared to other low dBa specked 40 mm fans.

It arrived in the mail today and initially did not work. My switch's previous fan was two pin and was wired Black, red. Where this fan was wired Yellow, Red, Black. After I swapped the red and black wires around and spliced them the fan worked perfectly.

It is dead silent in out small office rack and a welcomed upgrade. I never thought I would type 40mm and quiet in the same sentence but it works as advertised.

Cons: Only real con for me was I had to splice the wires to get it to work with my switch. Cost wise it's definitely an expensive little fan but well worth it.

5 out of 5 eggsCool and Quiet

Pros: Quiet. Moves a lot of air for the size and low speed.

Cons: Doesn't move as much air as higher speed fans, but then you should know that if you're looking at these.

Other Thoughts: I was able to turn a noisy, 1U security appliance with three high-speed, high-noise fans of the same size, into a quiet appliance that I could work next to all day and run 24x7 in a spare bedroom next to the other bedrooms in the house. The appliance still maintains a comfortably low temperature and you can no longer hear the fan roar in every upstairs room in the house.

5 out of 5 eggsUsed as Replacement fan for Cisco Catalyst 2950 router

Pros: Quiet operation, and although it does not move as much air as the OEM fan it does its job perfectly.

Cons: None

Other Thoughts: I had to rewire the pins to work with the switch, this is not the fans fault, as Cisco wired the pins different so there would not be a drop in replacement... This was rectified in less than a minute...

5 out of 5 eggsQuiet!

Pros: Very quiet. 3-pin connectors are easy to re-arrange for different pin configurations.

Cons: Expensive.

Other Thoughts: I installed 3 of these in a Netgear GS748T switch. The original fans in the switch were extremely loud, I measured them at 67dB from 1' away. After replacing them with three of the Sunons, the noise went down considerably - to 41dB. My server closet has now gone from very noisy to what I would call "whisper quiet". Not silent, but SO much better. Kind of expensive but if you are trying to keep noise down these do the job.

5 out of 5 eggsWork great

Pros: QUIET! Depending on how you install them.

Cons: A little expensive.

Other Thoughts: I installed two if these in my SUPERMICRO SYS-5015A-H. At first I had them drawing cool air into the case. They were pretty loud. I filpped them around to exaust warm air from the case. Now they are almost silent, and case temp was the same either way.

5 out of 5 eggsYou get what you pay for

Pros: Typically you cannot mention "40mm fan" and "quiet" in the same sentence. But with this fan you get what you pay for. It is DEAD QUIET. It does not move a lot of air b/c it is not a 9,000 rpm screamer but it moves enough to keep the air moving along. I replaced the 40mm Delta screamer in my 3Com/HP V1910-16G switch. The fan in the switch uses a proprietary connector, but a few minutes with the soldering iron and heat shrink tubing and I was done. The stock fan in SMB/Enterprise switches is designed to keep the switch cool while locked in a comm closet full of servers with no AC. In my air conditioned office this is a non-issue. The fan moves roughly half the air the stock fan does and you hear NOTHING. It's just as good as no fan at all, sound-wise.

Cons: It is sixteen bucks for one, 40mm fan...yeah, ouch. But it is worth every single penny if you need to quiet your device but still want to move some air through it.

Other Thoughts: This fan is NOT for replacing the 40mm screamers in 1U servers. It just does not push that kind static pressure. This fan is for replacing the one or two little screamers in switchers/routers/small PC cases.

5 out of 5 eggsGreat little fan

Pros: I used two of these to replace very loud stock 40mm fans in a Cisco 2800 router. CFM is much lower than OEM, but the stock fans are meant to cool the router forever in adverse conditions, and this one is running on my desk. The 12v pinout was easy enough to swap to match the Cisco spec.

Cons: None.

Other Thoughts: This fan is basically silent. It's pricey but worth it if you need moderate airflow with no noise.
