Anyone have experience with the SilenX Ixtrema Pro 120mm case fans?

Trying to increase the airflow in my case for better cooling. I noticed that the two coolermaster fans that came stock with the 4-3 cages don't really move that much air. So I'm in the market for a few 120mm fans.

These looked like they could do a good job, but before I buy anything I wanted to get some feedback.


SilenX Ixtrema Pro 120x25mm 14dBA

specifications

sku IXP-74-14
rated dba 14
dimensions 120x120x25mm
rpm 1400
cfm 72
operating voltage 8-14v
current draw 0.18A
power consumption 2.16w
bearings hybrid immersion
 
no way they'll be 14 dBA....not even Yate Loons at 1350RPM can be 14 dBA. the Cooler Master 120s are usually 1200RPM, which is why they don't move much air (especially when there's something impeding airflow). I honestly would go for some Yate Loons or Arctic Cooling AF12025s.
 
SilenX is the joke. Just an Adda fan with different sticker on the hub designed seprerate the unsuspecting form their money.

Yate Loon fans make for excellent low noise case cooling but probably won't push much more CFM then your Coolermasters. Try something like this triple bladed Delta.
 
Thanks for the info.

My main interest is replacing the front intake fans with something that will push more air from the front of the case to the back without getting something that sounds like a helicopter taking off

I had a yate loon fan that was really quiet, but it didn't feel like it moved enough air
 
Intake fans have almost no effect on overall system temps. Their main purpose is to direct the path of air flow and provide spot cooling for hard drives or other near by components.
 
So you're saying that replacing the fans I have now wouldn't make any difference? I'm not expecting my temps to drop like crazy, just figured more air movement from the front would help to push the air towards the back and out.

The Scythe S-FLEX SFF21F was another fan that looked like a decent replacement
 
I doubt you would see any difference at all, and if you did it would be very small at the cost of significant noise.
 
Based on SilentPCReview's roundup of 120mm fans, I purchased some Noctua fans. They will give you more CFM than any other silent fan at the same RPM.

In fact, I like them even better than the Nexus fans I own. The Scythe S-Flex was also well received by SPCR as well.

But that 14dBA rating is bogus. How can they even get a reading that low? Ambient noise for a quiet house is something around 18dBa.
 
I'm using one of their 120mm 38mm width ~90CFM fans. They are very quiet. Per their box the readings are taken in a soundproof room ad a distance of 1m. So I suppose in that setting it would hold true.

Nevertheless, I am pleased with how quiet their fans are so far. I'm thinking of replacing the stock 120mm fans in my Antec Nine Hundred with a few of theres that are at a slightly higher CFM rating.

SilenX's dBA specs are completely bogus. By comparing size, RPM, and bearing type you find the original Adda fan for nearly every fan SilenX sells. Magically all the specs are identical except the dBA rating.

Even if the 14dBA ratting was correct it would be far too low to useful. Unless you are literally inches away from the source, in near anechoic chamber conditions anything below 20 dBA is effectively silent.
 
SilenX looks nice, comes with the rubber mounts which are nifty, and are very quiet. Regardless of the dBA ratings, they are almost completely silent. Though I can't really say how much air they are pushing. I think under the packaging and paint they are just regular fans with reduced RPMs. The ones I have used seem to be of decent quality though.

Regular high quality fans with speed controllers would probably be the best option...let you set the speed you want or need.

Then get Noctua ones. Well reviewed, comes with a quiet mode adapter (like Zalmans) and also come with rubber mounts.

If you really like SilenX, then just get their equivalent Adda models because that's all they are, re-badged Adda fans with better ratings slapped onto them.
 
I'm late to this thread but, I have three iextrema 120's in my stuff draw that I stopped using because two of then actually ran HOT. After installing them I began to smell that peculiar smell of hot electric/electronic devices and shut the system down to hunt for the culprit. Couldn't find anything on my MB or other installed components so started the system up again thinking it just "new" devices giving off an odor until the "newness" burns off.

Odor persisted and grew worse. Shut the system down again and began touching everything I could to see what maight be hot - in doing so I touched the rear exhaust fan hub and it was too hot for my finger to stay on it. Started the system again and touched the spinning hub and it was almost blistering hot. Switched out that fan and replaced it with another iextrema ( I had just purchased two) - the same thing happened. Replaced the iextremas.

My uneducated guess is that the bragged about tiny hub that allows for greater air flow and larger fan blades also allows for a motor too small for the load of the large blades. I could be wrong. I haven't tried to run them to destruction - maybe after a while they loosen up and are OK - they cooled fine but got too hot for my liking so I shut them down.
This was about a year and two cases ago so they may be a much better product now.

Yes, Peter Kim is an ass,
Yes, The ratings for db are interesting to say the least,
Yes, Silenx may be rebadged Addas,
And yes, Addas are good fans.
My experience with Silenx has been good and had only 1 failure in 3 builds. They tend to push more air at good noise levels, sorry, I don't have a degree in sound or a db meter but my PC is less than 3 feet from my head at night and is on 24/7. I sleep well.

Who sells the Noctura fans in the US?

A few links I found here.
I've never used the noctua but I'm told they're good.
