Cooler Master Sleeve Bearing 80mm Silent Fan for Computer Cases and CPU Coolers-OEM Package

Pros: 4 in 1 pack, on sale, does what a fan does, not a jet engine

Cons: Cant make my pc hover

Overall Review: All in one set for when you need some extra fans, great when they are on sale

Pros: Great fans at a great price they work good push plenty of air I take care of several computers and always need spares on hand and these are perfect and the power leads are plenty long 12" according to my tape measure. rotation and airflow arrows very visible unlike some other fans I have gotten

Cons: not self installing

Pros: Very high performance vs. price Have lasted over 2 years and still going strong. When plugged into motherboard CAS FAN or SYS FAN connectors they run approximately 700 rpm and are fairly quiet.

Cons: They don't run as quietly or move as much air as some fancy case fans costing $11.99 each !

Overall Review: Some users don't seem to understand the variables when using case fans. If you connect a fan directly to a cable on your power supply using a large 4-pin Molex connector then the fan will run at maximum speed and maximum noise all the time. However, if you connect the fan using the small 3-pin connector (like the one that comes with these Cooler Master fans) it plugs into a set of 3 little pins sticking up on the motherboard labeled CAS FAN or SYS FAN. On this connection the fan will speed up or slow down depending on how hard the processor/cpu is working. When the computer is not working hard you get some airflow and fairly quiet operation. When the system begins to heat up the fan will spin faster and move more air and make more noise. If you need even greater airflow and lower noise then you should invest in a more expensive case fan with fancier fan blade design and fancier bearings. Also note that it's OK to run 2 fans off of 1 motherboard connector. You just need a fan power cable Y-connector which Newegg sells, of course!

Pros: Extremely quiet, cheap, and durable. I've had 3 of these spinning for 8 YEARS and they're still going strong! So I bought some more.

Cons: Airflow is extremely weak, do not use these in heat-intensive areas because they won't work. They're pretty good for minimalistic/budget builds and case fans in SMALL cases. Do not put these on heatsinks or radiators.

Pros: Ordered these on 10/31/2013 and they arrived in 2 days, which is about average for NewEgg. They run smooth and are fairly quiet, which is nice. + Got the 4-Pack Of 120mm Fans on sale for $10.99 after entering the Promo Code. Nice!!! + Two days shipping to get here. Nice!!! + They all come with 3-Pin Power Adapters. Nice!!! + A Good Company with good products. Keep up the good work CoolerMaster! + 1200 RPM

Cons: The only CON I really have is that most NEW Motherboards nowadays only have 1 OR 2 3-Pin AND/OR 1 OR 2 4-Pin Connectors on the Motherboards. Wish they had more as it would make hooking up more fans much easier. - Wish they had SOME Molex Adapters with them. Now I have to buy some. Oh well... - ONLY a 4-Pack!

Overall Review: These 4 fans are going into my NEW NZXT 210 (Part #N82E16811146075) I got recently for $29.99 from NewEgg (which I love). This is a GREAT CASE and I got it for a GREAT PRICE! I'm planning on using this case for a New Server I'm building. Now the only problem I have is that the case has room for 7-120MM fans and I've only got 4 (dummy me). Hey NewEgg, how about a Six Pack OR (better yet) an Eight Pack of these fans. I'm sure your customers would appreciate this. Now I'm wondering, do you have any other size 4-Packs available??? Like 80mm or bigger??? CONCLUSIONS: Would I buy these fans again??? Heck yes!!! Would I recommend these fans to others??? Heck yes!!!

Pros: Good airflow Noise isn't too noticeable

Cons: None

Overall Review: This replaced a fan with a High-Medium-Low switch, this didn't have that, but I knew that when I bought it. It works, it moves air and I don't need earplugs to sit near the PC it's in... what more could I ask for?

Pros: It works It's Quiet It fits

Cons: None

Overall Review: Good Fan for my HAF. I use it on the bottom to blow out the dust...maybe, that is sucked in the front. AT 20% off it was a reasonable buy

Pros: They all work and are quiet. They're fans. They spin and do the good air moving thing with the blades and the power and the wind.

Cons: Doesn't chop up a banana when banana put through the fan. Very inconvenient as this machine is located in the kitchen and takes up valuable counter space with no apparent cooking utility. I do, however, use it as a vent hood now.
