SilenX: the data and findings thread - Page 15

post #141 of 190

I dunno. I think that fans are very much effected b the application.

On the Ultra X cooler the fan is slap on the heatpipe fins surface--no shroud. On the PA 160 there is a good sized shroud. I think using a spacer and shroud is going to let any fan perform at it's best...
having something like that on a CPU cooler is hard to fathom--they are getting huger than huge already

TBH I a was really hoping to see a bigger Drop--I would like more headroom for cooling...it almost seems like the fan is not even a big factor on this loop--

Perhaps with a different rad it would be more obvious whether pressure/cfm/ disp[ersal are effecting the cooling. The PA is tremendously efficient and so it actually will cool the CPU wiith NO fan and convection currents alone...that's why I like to use it for Silent LC builds...

Attached the shots.

It got as high as 49 and as low as 47C...exactly like the SilenX...oh well...

$57 buck later...that's what I learned...nothing.

Going to the SilverStone FM121 now...back in about 15 minutes.

Well, you did learn something: Despite the differing actual CFM output between the San Ace and the SilenX, there seems to be a point of diminishing returns. In other words, there's a point where the air being moved by the fan simply won't decrease the heat dissipation in the system.

Just because the results themselves show no variation doesn't mean that the exercise is pointless. I'm willing to bet that, beyond a certain CFM output (who knows where that actually is?), temperatures simply won't come down any more. It's almost like a bottleneck at work, you know?

Keep it up, dude!

Bottleneck is not what I need here..I need a better range of sensitivity to point out the fan differences.

Oh well, let's plod on.

In absolute terms,, you're right. But, in real world apps.. Joe's right. most folks don't have cases that dissipate air worth a farthing, anyway. Nothing short of removing the components from the case is going to have any better effect.

So far the Silverstone FM121 is 47-48C...no surprise. That is how it ran last time too.

Face it temps are not going to be a big indicator..I am starting to question if this will provide any useful info for anyone...if the results are all the same then what are we learning? That I have too much time on my hands and am too willing to spend money...that's what.

Silverstone FM 121 loud as heck and atill just the same as the SilenX and San Ace 47C at load...

I am going to shut down and try the nex fan...an FN122 by Silverstone that last time failed to keep the CPU as cool as these three.

Time for something that is different--even if only a little...time for some FAIL

CyberDruid, I think it's ironic how you were all gung ho about these fans when you were selling them earlier; even stating clearly that you thought their ratings/specifications were correct despite others, including me, providing evidence to the contrary. Now it seems you've changed your tune, or at least are admitting that the ratings are off by a slight bit.

I have been saying for a while (well before this thread was made) that these fans are very picky with regards to their applications, only to be shunned by everyone and their mother. It's amazing how much people refuse to listen to someone that they don't deem to have the knowledge necessary to justify their opinion, regardless of how clear and concise any explanation provided is.

Edit: The second paragraph was aimed at no one in particular, just for the record.

please link me to the quote of me saying how I believed these fans put out 90cfm or whatever.

Please.

I am old and am losing my memory faculties so I cannot recall.


What I DO recall clearly is stating these are the quietest fans I have come acorss--the noise they make is not annoying to me and they push a lot of air.

Before you go dragging me into the mud please PROVE it. I have little tolerance for this crap at this point--even from someone with good intentions. I am STILL guing ho about these fans--but I am also provifing an impartial test. So far the test prioves my initial point: the SilenX work great in my apps.

All I have ever said is I think these fans proide the best cfm to dba ratio of any fan on the market. So far nothing has proven otherwise. I stand by that statement.

Here let me say it again.

The SilenX fans are the best cfm/cba ratio that I have found of all the fans I have bought or used. There.

Quote it, Love it, Live it...IDK

The fans here that I have tested are all way louder than the SilenX..at least so far.

The only fan that seems to be almost as quiet is the Hiper HiperFlow.

I am not even looking at CFM ratings in this test.. I am looking at a change in temps from one fan to the next.

I am running the fans full speed and they are all pretty annoying except the Fn122 and the HiperFlow--and the Silenx 64cfm...even the 90 cfm SIlenX is loud--but not in a way I find annoying...like the FM121 for instance...

For me, for my apps, for what I reccommend to others: iIlenX. THey look good--they perform well- they are quieter than other fans I have tried that provide the same or better cooling.

Obviously an 800 RPM silent case fan is going to be a lot quieter--but I would not be getting any cooling either.

I am looking to get a balance of cooling power/low sound. That's what I look for. getting the San Ace was more to try out something that Vapor likes...they are too harsh for my apps...

Of all the fans I have on hand (which is a fiar number) I would still choose the SilenX for my next mod. It works for me and my apps--if you have a GTX480 and want 8 push pull Panaflo High Speeds or whatever that is not something I care about. If you want to put a hella loud fan on your BT of Tuniq I could care less--I am looking for QUIET fans that work great. I found them: They are called SilenX.

That said the FN122 is made of FAIL for rad cooling--51C at this point...time for the next.

You have never had tolerance for people disagreeing with you or pointing out something you didn't like...

Taken straight from the horse's mouth.

Not a big deal bud, just something I thought was ironic.
