Introduction:

Case fans are often times one of the most important elements in a build. Most cases come with a variety of fans these days, but they aren’t necessarily the best for cooling, nor are they the quietest available either. Finding a quiet fan that has good cooling can be rather difficult. Many stock fans either move a lot of air and scream or move little to no air at all and are silent. Finding the right mix between the two is key in a quiet well cooled case. Fortunately, Kingwin has done some thinking and have a new design on the market. These 120mm case fans have a new mounting system that doesn't require any screws or tools. Rubber nubs are all that hold these fans in place so it will be interesting to see how it all works out. Today we look at a pair of the Duro Bearing Silent Series 120mm case fans from Kingwin.

 

Closer Look:

Fans generally come in some kind of bubble plastic packaging that makes it easy to see what they look like and cheap to package. These Kingwin fans are no exception. With the blue blade/white body/blue LED and the red bladed/black bodied/white LED fans to look at, we’ve got a nice sample of appearance options.

The fronts of the packages read 120mm in large letters to let you know what size you have got, in case you weren’t sure. It also lets you know what color LEDs are used, so you know what color it will be glowing in your case. The clear packaging leaves nothing for the imagination and you know exactly what is inside. The back of the package lists quick specs about the fans, these are located in the “Specifications and Features” (PAGE 2) of the review.

 

 

 

 

 

 

 

Out of the packaging, the fans take the shape of ordinary 120mm fans, except for one major and rather unique feature: rubberized corner mounts. If you’ve used the rubberized mounts for fans before, then you know what this material feels like. It’s soft, sound dampening, and somewhat hard to break. On one side of the corner there are the rubberized nubs for mounting the fan. The corners are completely removable to flip over and reverse the air flow direction.

 

 

 

Inside with the fan, a quick instruction sheet and 4 pin to molex connector are included. Not much to really show you here, just a piece of paper and connector – aren’t you excited?

 

A closer look at the fans and you can see exactly what “nubs” I’ve been talking about, in case you were still trying to form an image in your mind. The full corner comes off with a little effort, to be flipped over as mentioned before. Looking closely at the blades, you’ll notice they are pretty thin and have rather sharp points.

 

 

Looking at the fans side by side, it’s hard for me to really decide the color scheme I personally would want to own. However, from the features section there are five options to choose from:

The rubber grommet/corner pieces come in different colors as well and if you really wanted to have fun you could buy a few options and swap them around!

 

 

 

With the fans running, you can see the color of the LED lighting. The blue is a rather true blue, like most LED lit fans, while the red seems to be a little on the orangey/pink side. I have to again remind you, as I remind myself, the blade points are sharp – I did manage to take a chunk out of my finger taking these shots… I’m sure you’re a bit smarter, but I thought I’d take this chance to remind you not to put your fingers in running fans.

Testing:

The Kingwin 120mm fans, being identical in every way except for color, were put to the test together. I replaced the upper 200mm fan, with the two 120mm fans, as anyone replacing the fan might do. Using OCCT’s Power Supply Test, I loaded down my hardware for a solid 30 minute run to see how much more heat these fans could remove (both were mounted in exhaust) in comparison. HW Monitor was used to record the idle and load temperatures for the CPU, motherboard, HDDs, and GPU.

With it being the winter months and running a low gas bill, the ambient room temperature was 19 degrees Celsius, giving both the stock fan and Kingwin fans the same benefit in cooling. Since the room temperature remained the same for testing, the results show an accurate telling of which fans did a better job cooling. The temperature results from this testing procedure are shown below.

Summary:

The results of the 120mm Kingwin fans were rather impressive. The 200mm stock fan is a rather loud fan to begin with, especially for its size and a common replacement for many 200mm+ fans are 2 120mm fans, so the comparison was well worth a write up. First, I want to talk a little bit about mounting the fans, as they are very different from ordinary fansusing screws. The rubber nubs pull through the typical fan holes. I found this a little challenging with the 600T top spaces as they already have rubber grommets for screws to sit in. It was a little awkward getting the nubs through, but once I did the fans weren’t going anywhere. However, the nubs in general were a little hard to line up and install in such an awkward place, so I almost wish I had the option for screws.

Now as far as temperatures go, as that is your main concern in even bothering with changing fans, the Kingwin fans performed well. The temperatures for both the motherboard and CPU were decreased by a degree or two, even the GPU saw some benefit from the change. However, with the hard drives being so far down, there was no effect on them. So I know what you are thinking, a degree or two isn’t really worth buying two fans and changing them out. But, this is where the second most important factor comes into play, that these fans are quiet. To me, this is almost more important than the cooling itself. Personally, I cannot stand a screaming fan in my case and no matter how well they move air, I will not have Vantec Tornadoes in my build, due to my preference of noise level. Overall the swap increased cooling and decreased noise, both major positives in any change.

Conclusion:

In conclusion the Kingwin fans were very different from most fans. The mounting system was nice because it was tool-less, but also difficult because they were tool-less. Because of that, It’s hard to say whether it really benefited the fans or hurt them. Nonetheless, the rubberized material made the fans sit quietly up against the metal of the case, which was definitely a plus. The general fact is that the fans were quiet and cooled rather well – this alone makes them a decent product. Overall I liked the fans, but I would prefer the old school screw mounting system.
