Scythe SY1225SL12H 120mm "Slipstream" Case Fan

Pros: tons of airflow, very quiet for how much air it moves.

Cons: 1 out of 2 whines when the voltage is lowered using my aerocool panel, could be a panel issue or the fan, but at 12v stock it sounds fine. a bit louder than expected, see other thoughts

Overall Review: when selecting fans, you have to keep in mind that dBA is a logarithmic scale. in which an increase of 3 db is doubling the intensity of before, 10 db is ten times. also, from experience, i've found that the noise you hear from a computer fan is more the air rushing than the fan. so to get a good idea of what they advertise, imagine just listening to the motor run, without fins. a fan pushing air past a grate will also be much louder than the same fan with a clear path.

Pros: I strapped in four of these in my antec 900, I'm shcoked at how quiet these are. For 88CFM it's amazing.

Cons: Too much air? Can you ever have too much air?

Overall Review: The lack of LED's are refreshing. I had a tough time finding fans that wouldn't light up a small town.

Pros: they Were very silent for a nice long 5-7 months, and moved a respectable amount of air.

Cons: after a few months the fans actually started to fall out of the frame, happened to 3 out of 4 in under a year with the first going out in 2-3 months. i still have 1 left in the back of my CM cosmos that's mysteriously still working well.

Overall Review: Case is always kept dust/pet hair free and they all broke with out any noticeable cause.

Pros: IT BLOWS LOTS OF AIR WITH A CIRCLING MOTION

Cons: NONE

Pros: Quite and powerfull, pulls plenty of air into case and keeps it cool

Cons: none

Pros: Much quieter than I expected. Seems to move the amount of air it is rated for. These are by no means silent, but they are easily the quietest 120mm fans rated over 80cfm that I've ever had my hands on. Also, compared to the 1200 RPM version, this version does an excellent job where a higher pressure fan might be needed. I was surprised by that because the 1200 rpm, 1600 rpm, and 1900 rpm models are of identical design but for rotation speed. The 1600 rpm model performs well behind fan filters and on my water cooling radiators where the 1200 rpm model really didn't impress me.

Cons: This isn't really a con per se, but it is a sleeve bearing fan. Anyone purchasing case fans should really find out what the differences are in bearing technology before purchasing. Sleeve bearings are not as durable as ball bearings and fluid dynamic, etc.

Overall Review: I think the 33db rating is stated high. I think these are a bit quieter than that. I have some of the 1200 RPM slipstreams and some of the other reviewers had me worried that these 1600 RPM versions were going to be much louder. They aren't. In fact, if I remove my fan filters, I can barely tell the difference audibly. I'm very pleased with the balance of volume of air moved versus noise level and I intend to buy more. I would not hesitate to recommend these to anyone willing to use sleeve bearing fans.

Pros: quiet. Moves alot of air. Works great with my corsair hydro H50 radiator. no fancy LEDs I have this fan limited to 60% speed in the bios. This fan acts as my only exhaust fan. at 60% it moves a good amount of air and a low noise level. definitely recommend.

Cons: cable is a bit short, not sleeved

Overall Review: I walked behind my computer one day when i had this fan at 100% during stress testing and felt a strong warm breeze on my face and arm. I was standing 8 feet away! This thing blows.

Pros: Moves a rather large amount of air for the decibel level. Can't actually hear them over my tuniq 120 (old version) if it is at 2000 RPM (which it always is). Amazing sale price at the time of purchase - 9.99

Cons: None at this time
