Scythe SY1212SL12H 120mm Case cooler

Pros: These are 12.5mm thick fans. When the 25mm are too thick, this will be your choice. I really like these fans.

I am using another one of these (1,200rpm SY1212SL12L) to cool the processor chip on my RAID controller... I'm using a PCI slot cage to hold the fan as I had a clearance problem with typical 25mm fan setups.

And guess what???? There is a rheostat controlling the speed of the fan... MB reports it is running at 900 RPM and temp probe reports ~20 degrees higher than ambient for the RAID chip. Good stuff!

BTW, I think the decibel rating is a bit conservative... When running at rated rpm, it doesn't make much noise. Which is unlike the equivalent 25mm fans.

Cons: Fan does not have the sturdiness of the 25mm fans... I'm referring to the blades/spindle assembly. This is sort of to be expected, all things considered. Must treat these fans with respect. However, the frame is sturdy. NO EGGS OFF!

Other Thoughts: Hard to find... I ordered more from Newegg and was told... only one left, want it? Sorry fellas... its sitting my stash.

With my setup, the rheostats will turn the fan speed all the way down to 350 rpms (per MB reports) and as high as the rated RPM (again, per MB reports). When set, the rpm is very stable, varying very little.

Pros: They don't make fans slimmer (in depth) than this. It pushes air.

Cons: These fans are not at all suitable to be mounted horizontally. I had 2x mounted as exhaust pull above my H100 rad. (in push-pull config.), above the blowhole (top grate) on my 600t case. About the second week after installation, whenever the fans would spin up, they would scrape the top of the blowhole grating and make a horrible noise. Upon further examination the plastic holding the fan rotor/ blades to the fan body is just too thin and flexible to be mounted in this fashion.

When I connected these to my H100 controller, the speed control made these fans' speed oscillate rapidly. They would go from acceptable noise levels to sounding like an RC car and back every 10 seconds :-|

Other Thoughts: Don't know what I expected from a 12mm depth fan, but I was still disappointed. R&R'd both with YLs. I guess I'll hold on to them until I find a vertical application that requires a fan this slim. If something sounds too good to be true, it is.

Pros: Very Thin at 12mm
Very Sturdy Good Motor
Moves a Decent Amount of Air
Great for Custom Rigs

Cons: Pricey
Not Always in Stock
Not as good as an equivalent fan in 25mm thickness
Blades are Thinner so a little bit of increased noise level
May need to use different screws due to decreased thickness
Wish they had a little more static pressure, but cant fight physics

Other Thoughts: I used mine for a push fans for my H100 corsair since a regular thickness fan would not fit, seems to be working well, noise isn't a problem because i have them on a fan controller.

Pros: This fan moves quite a bit of air.

Cons: the fan is super loud.... like someone in an earlier review said, its like you have fighter jet simulations going on in your case.
also AIDA64 as well as AI Suite II clock the speed at a max of 1600 RPM even though its a 2000RPM fan.

Other Thoughts: (USED AS A SIDE FAN) Really the noise doesnt bother me THAT much, and the low profile was necessary because my old rosewill side fan was hitting the Cooler Master 212 Hyper Evo causing the fan to move around whenever i closed the side panel.

Pros: Just the right size to go in my ROSEWILL BLACKHAWK tower. There is area for a fan to help cool the motherboard off on the case. First I had it hooked right the power supply....and it sounded like a hair dyer. So, after I connected to my Fan Controller, it was bearable...

Cons: None...

Other Thoughts: Great for those hard to reach spots...

Pros: Good fan, Low noise, Slim.

Cons: Didn't push as much air as i thought it would. Still a good purchase to get that hot air behind the motherboard out.

Pros: fantastic fans, move alot of air for being so thin

Cons: none

Other Thoughts: I got these for my Hyper 212 Evo because the stock fan was a dud AND that heatsink is a bit hefty for my case in terms of ram heat-spreader clearance. I put these in and everything fits like a glove. I also like the japanese writing on the box that I don't understand but I think looks cool because I don't read Japanese.

Pros: Very very slim

Cons: So loud I could hear it 2 rooms away when it runs on high

Other Thoughts: I bought this item because I needed a fan in a tight space and I needed to to always run on high. When its on low you do not notice it but on high I heard it 2 rooms away (and my 180 Silverstone fan on high is whisper quiet). returned it!

Pros: Works as advertized, it moves air

Cons: now people have different definitions of loud, so when I say this fan is loud, I mean JET ENGINE LOUD. This fan was louder than all my other fans combined (even with them all ramped up, with my caviar blue and DVD rom both at full speed). I mean its louder than my ceiling fan on high.

Other Thoughts: I also have the 1200rm slipstream, it is very quiet. It does not move a lot of air but serves its purpose.

Pros: Thin! Quiet! Moves a ton of air. I am using these fans on a Corsair H100. mounting was a bit tight in my case for the stock fans. They cool better and are quieter than the fans included. Unladen temps around 28°C.

Cons: It would be nice if the 3-pin connector was a bit longer.
