The best case fans ever made?

I was browsing the web and I found this website:
http://www.silenx.com/ixtremaprofans.asp?sku=ixp-76-18

dBA: 18
Size: 120mm
RPM: 1400
CFM: 90

My frontfan is only 25CFM, my backfan is only 15CFM.
If I replace those fans with 2 of thse silenx coolers, I will have a SERIOUS temperature drop!

I never heard of silenx, but now I will never forget that name!

If someone knows something better, please let me know!

I am going to buy 2 of these next month and I will post a nice review after installation

 

silenx is known to be very optimistic about their ratings.
here is a test of one of their fans, it doesnt even come close to its specs;

that said, its very well possible that this is a very good fan, just dont believe the ratings

 

Here's a review I found: http://www.overclock3d.net/reviews.php?type=3&id=57&page=1&desc=silenx_ixtrema_80___120_quiet_fans

Mike.

 

I use "user-reviews" ( not by a review website ) to compare coolers, and this is what I have found so far:

The last guy sas that he can hear the "woosh of air". But isn't that normal for 90CFM? As long as the fan itself is not making to much noise, who cares?

One question:
#3 talks about dynamic pressure. What's that?

 

As I have already said in the other fan thread, I have one SilenX fan in my case and it's doing a good job on the cooling but I wouldn't call it silent. The 18dbA are not realistic, not even close. But after seeing the overclock3d.net review, perhaps I've just got a faulty one? No, faulty would sound different I'm sure, it's just noisy.
Can't recommend them.

 

Do you have the IXP-76-18? Or an old model?
And were you able to use the cilicone vibration dampening mounts?

 

here are a few more user statements:

sorry for driving my point home that hard, but i want to prevent people spending too much money on something that isnt worth it. if they were priced like other fans, i wouldnt do that much effort, but at that price, its just ridiculous.

 

Nope, I don't have that model. I've got the IXP-74-14 (14 dbA / 1400 RPM / 72 CFM). That should be even quiter but I can definitely say it's not. Also using the rubbers.

 

I've read on many forums that the main reason for the higher dBA is the air:

So it's not the cooler but the CFM. Maybe it's impossible to get a low dBA with 90CFM. But I doubt that they make more noice then the 8800GTS cooler at full speed ( I always have it running at 100% ).

 

I always use akasa case fans if I need any extra.

I have a 120mm akasa in the door of my antec 900, and it is either silent or at least inaudible over the noise from my cpu hsf.

 

the noise that comes from running a fan originates from both the fan itself(mainly the motor and frame vibration) and (mostly)from the air it pushes. as the air is pushed along by any fan, it starts to twist(i cant find a better word for it), making noise, so higher CFM will mean more noise. so no matter how good your fan is, there are limits as to how much CFM you can push at a certain noise level, and those silenx fans are definitly violating the laws of physics.

just think about it: if they are that good, why havent the other fan manufacturers started to copy its design?

 

Seems like an honest guy

 

I recently just posted a thread about 120mm fans and which are better. I am actually switching from that silenx fan. 18db is an outright lie. The fan is louder than a hairdryer, to some people it doesn't bother them as they play with headphones on and whatnot, but to me I like my case decently silent. They do move a **** ton of air though.

 

What about this cooler?
http://www.silenx.com/ixtremaproledfans.asp?sku=ixp-74-14l

Is there anyone who has good info on this cooler?

 

I beleave you 100%. Is the fan louder then the 8800GTX cooler at 100%?
If it's not, then it's ok by me.

You say "they do move a ton of air". Can you confirm that it's really 90CFM ( 70CFM in the wurst case )?

Like I sad, if it's really good at cooling, and it's not loader then a 100% VGA cooler, then there is no reason why I shouldn't buy it.

My 8800GTX's are watercooled atm, so I couldn't tell you how loud it was compared to them, although I'd say it's louder then a 7900GTX fan. As for the CFM, i don't have the exact measurements, but it blows more air then my 72CFM Thermaltakes, so i'd imagine it hits 80+.

 

Higher then 70CFM? Damn...

 

Omg, 65db

ordered three of these, and they arrive in a few days. i hope they do a better job than my stock fans. anyway, ill update the thread with my findings after i install and run them.
