I need a recommendation for some quiet 120mm fans. I have a TT Tsunami which is kind of loud. Should I replace the fans or go with a fan controller? If the fans what do you recommend?

Specs: P4 3.4 LGA775
Asus p5p800
BFG FX 5900
Samsung 80 GB
Plextor px-712a
Pioneer DVD-ROM (forgot what model)

Many SilenX bashers in this forum, but I recommend them strongly. They are expensive, but cannot be beat by anything out there for their cfm/dba ratio. Many will say that dba ratings are different for all fan manufacturers and this is true, but Silenx's dba ratings are as true as they come. I have the Tsunami and 2 120mm 58cfm 14dba fans. Those Yate's just dont push enough cfm's for an overclock in my opinion, but are inexpensive. If you dont OC then I suggest the 11dba Silenx's @ 40cfm's

SilenX fans have a thermister and adjust their rpm depending on temp. They may be quiet when running on low speed but I doubt they make less noise than the Yate Loon's at the same rpm.

Bottom line, the SilenX fan specs are BS.

Try again.

I've never used a SilenX fan but I'm going to call bull $hit on this. There is no way a 1600 rpm fan is going to be QUIETER AND PUSH MORE AIR than a 1350 rpm Yate Loon. Sounds like SilenX is testing db's using some BS method.

According to the Yate Loon web site, the fans I listed are rated at 1350 rpm, 40.0 cfm, and 28 dB.

The SilenX 120 mm fan is rated at 1600 rpm, 58 cfm, and 14 dB.


I'd love to learn the physics behind this black magic;)

Try again.

Like I said :)

You might also want to consider getting a fan controller. 120mm fans are loud no matter which quiet one you buy, due to the amount of air they push through.

Nice edit :) No Ed you are incorrect. All but 1 do not have a thermistor. Only the 80mm does. They have what is called a resistor. There is a difference. My bad on the cfm earlier for the YATE you spec'ed out. I did not know they pushed 40. That would be fine in BigJoe's case and cheaper then the SilenX. Its all good and SilenX's fans are quality products as I have been using them for a while. Their specs are right on. Try 1 Joe and return if you do not like. G-Luck

Easy fix = cut your grill out as this cancels the "swoosh" noise of air coming through/going out of your case.

I edited my origional post after reading a review of the 80 that had a thermister. My bad to assume the 120 has one as well.

Basically I was trying to understand why SilenX could make such BS claims of airflow and low noise. There is no way they can move 18 cfm more air than the Yate Loon while being 14 dB quieter. NO WAY.

SilenX may make a good product, but their marketing specs are untruthful. Plain and simple.

Even without a fan grill, a Panaflo 120mm low fan is way to loud in my opinion. But I'm damn picky about my noise ;)

If you have not used one how can you say this? I have not used Yate's, but yet what makes their stats truthful and SilenX's untruthful (in your opinion)? Anyways I will get a analogue noise meter from my Boss this next week and run some dba tests on SilenX/TT/and Delta fans and post the results. Shoot for 7$ I'm gonna order some Yates and do as well. I'll do the test from 3 meters down to 1 meter in a 10x12 room with wood floors and some basic furniture. I'm curious. -->http://www.directron.com/noise.html interesting read here.

LOL I'm a noise freak too. Is that the "high speed" pannie?

even if you do use a fan controller, the quality of fan matters. You should about a 2000RPM fan if you plan to get a fan controller. I know my 120mm Vantec Stealth (1500RPM) does not start at 5V, but my Antec 120mm Pro (2000RPM) does.

Back to quality matters, even with my Vantec spinning at 950RPM (about 7V'ed) it has definite motor noise. Unlike my Antec fans at 1100RPM, which are quieter. My 92mm Nexus (Nexus is made by Yate Loon) is even smoother. I haven't had a Panaflow fan, but lots of ppl say they are really smooth as well. If you're not a real silent freak, you probably won't notice these differences too much and undervolting lower quality fans (Vantec, ThermalTake) would probably be just fine.

I'm sure SilenX do make quiet fans and quality fans. but their ratings are complete BS. I mean, it's physically impossible to make a mechanical fan work in those specs they put out.

If I remember correctly, SPCR had some info that SilenX as well as Nexus were both really manufactured by Yate Loon. It was shortly after the controversy over there when the owner of SilenX got himself permanently banned from those forums. (He was registered as a few different users trying to promote his product.)

I can only remember seeing one reviewer saying he thought SilenX fans were loud though. That was after he removed the inline resistor.
even if you do use a fan controller, the quality of fan matters. You should about a 2000RPM fan if you plan to get a fan controller. I know my 120mm Vantec Stealth (1500RPM) does not start at 5V, but my Antec 120mm Pro (2000RPM) does.
It's not the rpm's that cause this. It will vary from fan to fan whether or not it will startup @ 5v. Most specs say 6-12V. When I received the 2 Yate Loon 1350rpm fans I ordered, I cut out the closed corners and mounted one (decoupled) inside my wifes Fortron FSP 350PN power supply. It started and ran fine voltage regulated. It was dead silent. Matter of fact I put my ear inside her case, turned off her case fans and set her cpu fan control at it's lowest setting. I couldn't hear it at all. All I could hear was her WD 800JB hard disk whining like a banshee! In this application, though, I am going to replace it with a Globe fan because her case temps rose too much. That power supply needs more airflow to effectively remove heat and it regulates fan voltage from 4-11.3V. The Globe (very quiet also) has about 20cfm more flow @ 12V.

(edit)
Oh...forgot to mention.
I have my sons TT SViking case apart here replacing his (loud) TT fans and his hs/f. I did a test fit and fired it up and WOW it is quiet now. (Globe 120mm exhaust, Yate Loon 120mm intake, Thermalright SI-97 w/ Evercool Aluminum 92mm hs/f)

How can I tell that these are Yate Loon's? Is there a product number or something? I don't really want orange fans.:)

thanks for all the info.

I can verify those are Yate Loon (That's where I got mine)
Model number is D12SL-12.

"Yate Loon" is molded into the frame of the fan:)

I guess what I meant is does ISELLSURPLUS have other Yate Loons that aren't orange. If so, how do I tell that they are Yate Loon's?

The CFM/dBa ratio is meaningless!
CFM is a linear unit. dBa is a logarithmic unit.
In other words, if you double CFM, you always double the amount of air moved.
But, if you double dBa at for example 30, you will be multiplying noise by a number much larger than 2!
