4 out of 5 eggsSolid Fans / Great Price

Pros: * Good Price For 4 Fans
* Solid Build Quality
* Fairly Quiet
* Brand Name

Cons: * Low Air Pressure
* Shipping Via OnTrac Is STILL Inadequate

Other Thoughts: Overall, this was a great purchase and I like the fans. I still have issues with OnTrac being a less than adequate shipping carrier. They didn't even make an effort to deliver my package to my apartment door. They instead dropped it directly at my apartment office and left no note or paperwork notifying me of its delivery. This is unacceptable for a delivery service. Upgrade your shipping option in hopes of bypassing this ridiculous carrier.

5 out of 5 eggsAwesome

Pros: Quiet
affordable

Cons: not ferret resistant

Other Thoughts: On a serious note, you can't beat this price. Cooler master name brand gear and there's four of them. Quiet fans and the cords are pretty tough as I've tied them into weird positions for cable management.

4 out of 5 eggsNot sure how much they do

Pros: Definitely spin. Run very quietly.

Cons: Very thick, cheap build. Doesn't feel like a huge amount of airflow is being generated by them.

3 out of 5 eggsYou get what you pay for...

Pros: Cheap

Cons: Really low CFM's,
Abysmal Static Pressure
Wear's out quickly
Non Sleeved or Heat Shrink Wires

Other Thoughts: My thoughts on these fans are pretty clear. If this is all you can afford or want to spend on fans then this is what you should buy. But remember the age old proverb. You get what you pay for.

These fans push out an abysmally low amount of air and almost no static pressure. In my opinion the savings just isn't worth it because your temps are going to suffer greatly because of it. They also are cheaply made and don't last long so be prepared to replace them.

My biggest issue with these fans isn't their horrible performance though. It's their price to performance ratio. I'll explain what I mean.

These fans when they are on rebate are roughly 2 dollars a piece. There are so many better fan options for only a few more dollars a piece and with an air cooled rig fans are very important, I mean they are the only thing keeping your PC cool, why wouldn't that be a component to invest in? It's just like the PSU. Don't cheap out, because even with more expensive fans it still won't be much.

My Fractal R4 for instance holds 6 fans. You could get 6 Cougar Vortex 120mm PWM fans on rebate for 42 dollars. or about 7 a piece. What is 42 bucks when it comes to cooling? They will also last longer.

Another option if you don't care about looks and you are all about peformance go over to e bay and search Delta AFB1212H. For only 10 bucks a pop ( at the time of writing this) you can get a 120.. fan that push out double the CFM's (most likely more considering quality control on these Cooler Master ones) and the static pressure on them will blow these out of the water.

5 out of 5 eggsPerfect!

Pros: I built a computer over a year ago and only installed one fan. The heatsink fan has been extremely loud and very annoying ever since (my wife tells others the computer sounds like a hovercraft). I bought this 4 pack and only installed 2 of the fans into the computer. The difference is amazing! the computer is now extremely quiet even though I added fans to it. I will be installing the other 2 fans into my next build.

Cons: Honestly I would like to say my only complaint is that I didn't install them sooner....But I will add, I wanted a red LED fan in the rear of my build to compliment the blue LED fan in the front. I went with cheap, basic, and plain.

Other Thoughts: I've only had these installed for a couple days when I wrote the review. I don't plan on these failing me, but if they do at some point I really cant complain. Maybe then Ill buy the red LED fan I want.

3 out of 5 eggsthey are decent

Pros: -they move enough air collectively
-relatively cheap
-came quick (that's more of a carrier pro than the product its self but oh well)

Cons: -these are far from the quietest fans on the market

Other Thoughts: You are better off buying something a little more pricey (20$ 2 packs for corsair led fans are a much better value) but in a situation where you are on a serious budget or just don't care about how loud the computer is (with headphones i don't even notice them), these will work.
