Dynatron DF1212025BM-3/4G Case Fan - OEM

Pros: They move a lot of air.

Cons: I placed two of these to draw airflow up from the bottom of my case. They pull a lot of air but are loud. Problem solved with two fan silencers.

Overall Review: Not bad quality for the pice. Depending on where they are placed, they can be loud.

Pros: This is an excellent fan with 2 ball bearings. That means it will have a guarantee that it will last for a quite a while.

Cons: This fan does not have precision in its manufacturing, because the fan blades are about 4 mm away from the shroud, reducing the airflow performance.

Overall Review: I modded the fan by taping inside the shroud with double side foam tape. That increased the airflow and the noise has been reduced. Cheap fan with great bearings and performance, what more could you ask for?

Pros: Great fans, quiet for the amount of air they move.

Cons: None

Overall Review: Using 3 of them in a Antec Three Hundred case, its a great combination.

Pros: good air flow with 4 of these in a coolermaster 690 case. helps keeps cpu temps at 41c max. the other 3 fans came with the case.

Cons: the noise does not bother me. the sound is a little high pitched and i perfer low pitched sound. however i put a vantec dampener kit on and it slightly lowered the pitch.

Overall Review: no problems with these fans.

Pros: these fans are great. i bought 5 and they do what there suppose to. if your worried about sound dont buy these there LOUD. i bought them knowing this but sound doesn't bother me.

Cons: none

Pros: A little loud, but very efficient. After installing two of these, my graphics card no longer runs it's fans at full or near-full throttle. I guess I can fix that by overclocking my graphics card...

Cons: More efficiency = More noise

Pros: It moves a lot of air. I know everyone is saying that, but to further emphasize the point, I will too!! It also has the ever-so handy 3/4 pin power connector.

Cons: It is rather noisy. It's the noisiest fan that I have by far. I was kind of expecting that seeing as it's 120mm as 2200rpm, but I will dock a 1/2 egg anyway. The other 1/2 egg comes from it's effective-ness. It cools my Idle temps a bit (down about 5C), but barely does anything to load temps which is more of what I wanted. Under load, I still exceed 75C... which is a problem. I'll probably buy a different CPU fan/heatsink to acompany this fan.

Pros: Quiet, and this things moves a lot of air. I noticed a huge change in all of my compontent temps.

Cons: None
