Pros: 1. you get 4 good quality fans for a good price 2. they don't make a lot of noise 3. they push a good amount of air 4. It's cooler Master, so you know they stand behind their products 5. They work good enough for both air flow and static pressure 6. They came with mounting screws

Cons: 1. Non sleeved cables so you see the ketchup, and mustard cables if you care about that kind of thing 2. No LED if you care about that kind of thing 3. They are 3pin not 4pin so no true PWM control 4. They did not make me a cup of hot tea, and cook my breakfast(yes I'm being sarcastic)

Overall Review: I would recommend these fans to anyone on a budget looking to replace 120mm case fans, but do get a 4pin PWM fan controller so they can run off a motherboard header. I have 3 of them running off a deep cool PWM fan controller with 2 of the fans attached to my Enermax ELC-LMR120-b.s Liqmax II 120s AIO in push pull at the front of my Fractal Design Core 1000 MATX case with a 3rd on the side panel drawing in fresh air with a metal dust filter, and 1 92mm Cooler Master Silent Sleeve barring fan as the exhaust fan(largest the case supports in the rear), it cools about 5c to 10c better then the stock "Batwing" fans on the Enermax with 1/4th the noise, and I'm cooling an AMD AM3+ A10 6800B APU turbo clocked to 4.4Ghz and the GPU OC to 1013Mhz, and my max temps in the low/mid 50's when gaming, YouTube or light video editing of old VHS home movies to DVD. So yes do pick up these fans at a great price if you are on a budget, and care more about performance and low noise than looks.

Pros: The price was good, and it fired up when i got it, did not go up in smoke, or a ball of flames

Cons: did not last very long and would have to hit my power button on my PC several times before it would come on after about 2 weeks, and now it's dead as a door nail with any normal load on it(will turn on if jumped, and nothing hooked too it), and I bought it in March 2015 and now it's July 2015 of this review

Overall Review: unless your powering a very very low wattage system stay far far away from this low quality junk, and I honestly hate writing bad reviews but this is not the first power supply from this company I've had go bad.

Pros: caught it on sale for less then $20 it fights in smaller midtower MicroATX cases it cools the FM2+ platform well the included fan even at full speed is not too loud

Cons: it was a bit hard to get the clip installed with my mobo already in the system replacing a failed 120MM AIO setup.

Overall Review: Great cooler for AMD if you can get it for under $20 I still had to source a slim 120mm side panel fan for my Fractal Core Design 1000 case for everything to button up well which is not really con, but should be noted, and the only reason I took off an egg is again It was a bit frustrating to install, and has been to do again when I change my thermal past during yearly maintenance.

Pros: The price was right for 64GB, the package was easy to get into unlike some other brands, and it works great formatted as internal storage for my girlfriend's Moto E5 Play Android phone.

Cons: It did not butter my toast for my morning breakfast lol

Overall Review: If you are on a budget G.Skill has you covered, and it's from a seller you can trust, unlike the random Chinese sellers you have never heard of on other sites, that might be selling fakes, and/or duds.

Pros: Keep my AMD A-10 6800B turbo clocked @ 4.4Ghz nice, and cool usually in the mid 30's(34/35C) sometimes in the upper 20's on cool mornings on normal daily work loads, and never reaching higher then the mid 40's(44c) when I'm pushing it hard gaming or rendering out home movie footage from VHS to DVD, plus the price is good considering other 120MM AIO.

Cons: Installing it on my Fractal Core Design 1000 was a slight pain having to remove the motherboard because of no CPU cutout, and a side drive rail because it could only fit in the front of the case, plus the fans are a bit loud(took 1 egg off because of that).

Overall Review: If you don't like loud fans I would suggest picking up 2 quieter 120MM fans from Fractal, or Cooler Master(have had good luck with both companies), and I'm not 100% sure if my temps are because I have it installed in the front of my case, but do give this AIO a shot if you are on a budget, tired of Air coolers not performing well enough, or don't feel like doing custom water loop. Cheers, and happy building. :-) Edit: After almost 1 year of usage, the cooler is still going strong, but I did replace the fans with much quieter 120mm Cooler Master silent fans, and which dropped the noise levels to a 1/4 of what they where, and the fans cool just as well as the included "Batwings" fans. It's a good AIO at a good price, just pick up the Cooler Master 4 pack of 120mm silent fans for cheap to make it an even better cooler.

Pros: it does it's job well as an exhaust fan on a Fractal core Design 1000 it does not make a lot of noise it not overpriced it came with case screws you Cooler Master stands behind their products

Cons: was more expensive then a cooler master 4 pack of 120mm silent case fans did not cook my breakfast(yes I'm being sarcastic) no 4 pin no sleeved cables if you care about that so ketchup, and mustard cables no LED's if you care about that

Overall Review: could use even a rubber sleeve, but at this price point I'm nitpicking, so yes if you are on a tight budget need this size fan, and don't want it to make a lot of noise while still pushing a good amount of air this is the fan for you.

The seller sent exactly what I ordered, at a fair price, as the flash drives where legit, but shipping was a bit on the slow side with a 10 day turnaround using USPS, otherwise I would buy from them again if needed, and not in a hurry.

Sent the power supply I needed for my Chromebook fast well packed, and at a fair price, would use this seller again if needed.
