Fan too good to be true?

Merlin7777 · Oct 8, 2006

Has anyone hear about or ever tested or used this fan?

It's specs are great, but I am a little skeptical. Anyone know anything about it?

SolidxSnake · Oct 8, 2006

that doesn't seem too unbelievable. around 40dBa for 110CFM. Probably a little noisier.

Merlin7777 · Oct 8, 2006

I don't know alot about fans right now. How loud exactly is 40 dba? Like a vacuum cleaner, cause I will pass.

Tyreal · Oct 8, 2006

Just go for a Panaflo. They are just about the best fans you can get.

Some will say it is pretty loud. I myself wouldn't want my fans at 40dBa.

Depending on the fan, that 40dBa will be motor whine, the sound of the blades pushing air, or both. Fans also give off different pitches. Occasionally, there's a fan that is loud, but has a low-pitch to it, so it's bearable.

I've never used that fan so I can't really comment.

40dba is loud. Go for 25dba or less if you value a quiet atmosphere.

40dBA is relatively quiet. A dustbuster is about 75dBA, and an upright or canister vacuum is usually much louder. The loudest fans people use in their computers are generally around 65dBA, which is similar to a low-speed hair dryer at arm's length (much quieter inside a case). Do you have to use a 120*25mm fan? If you can use 120*38mm, try this fan. Relatively quiet and more airflow, from a trusted manufacturer. I wouldn't trust the 110cfm rating given for your fan, but Panasonic and Delta usually have reliable ratings.

Use the first one if you want quiet, and the second one if more airflow is important to you. Personally, I'd go with a 220cfm, but I don't mind a bit of noise.

I happen to have the second fan linked to in the quoted post. It moves a very good amount of air, at 7v, and it very quiet. Once I turn on my music, or start gaming, or even turn on the TV behind me, I can't even hear this fan. The only problem I have is that I wish that I would have gotten the BX model so that I could use the tach output with my fan controller. I had to disable the low fan speed alarm otherwise it is constanly going off.
Edit: I believe that fan can be had from SVC for about $5 less. http://www.svc.com/fba12g12u.html It is currently out of stock, and the price is $11.99. They are very good about shipping, I usually get my orders from them in about 2 days, and usually at a very reasonable price.

I have that fan (the silverstone fan) on my heatsink. at full speed it is loud, I'd say louder than 40db. but it will push a TON of air if you so wish. it's really quiet until about 1300- 1400 rpm. I couldnt say how much air is pushing at that point but its mroe than enough for me.

WonderingSoul · Oct 9, 2006

Not a lot of air but whisper quite. You can't even hear it run:

I have four of the 80MM fans in my case and she's near silent.

Merlin7777 · Oct 9, 2006

thanks for the recommendations guys!
I read somewhere on the forums that it is you will not see a difference after a certain point when using a high cfm fan with a ultra-120. Is that true?
Keep in mind that I am going to be cooling a e6600 with this, so I do not anticipate alot of heat generation, even though I plan to overclock to around 3.4ghz, if not higher.
Obviously, what I am looking for is the best performance to dBA ratio.

P.S. You guys rock for the fan recommendations.

ok well 40 db is VERY VERY loud for me at least... anything over 26ish is too loud... i have an ultra 120 on top of my e6600 and it is being cooled by a Yate Loon

http://jab-tech.com/YATE-LOON-120mm-Case-Fan-D12SL-12-pr-3009.html

for $3.70 you CANT go wrong... this fan keeps my e6600 right at about 42*C full load @ 3ghz as reported by TAT... but the IHS temp as reported by a thermal probe never gets over 85*F in a 75*F case

OH and BTW im idiling right now (browsing net and listening to music) @ 37*C with ALLL fans (all 5 of my yate loons) @ 6volts!!!

Merlin7777 · Oct 9, 2006

Thanks for the info nd4spdbh2.

Yate Loons huh?

I have hear good things about them, but then again I have also hear good things about panaflow.

P.S. what do you think of this scythe?
http://www.sidewindercomputers.com/scsf49cfms12.html

It moves more air while being quieter than your yate loon. Of course it is about +$10.

Brando · Oct 10, 2006

That scythe is probably a good choice. I had the fastest version but had to sell them because they make a funny noise when you undervolt them. The middle speed one should be just about right and the (supposedly) super high reliability is a good thing for a cpu fan since you'd be less likely to notice it fail than a case fan.

MaxPowers_68 · Oct 10, 2006

It also it depends how close you have the computer to you... i have mines right on my desk pretty close to me and i can barely hear my 25db 120mm. The HD whine is more noticible.

Hate to say it but a low-speed hairdryer didnt even come close to the sound my last computer made. It was so loud that you could not hear someone talking to you from more than about 10-12 feet away. I haven't seen a hair dryer that is that noisy, not to mention a low speed one. Also the fans were not even 65dBA either they were in the 50s (54-56 I think).

Merlin7777 · Oct 10, 2006

^^
Ha!Ha!Ha! That is pretty funny. How many fans did you have in that thing?

scythe... ehhh i have one of their 800rpm models and it has an audible motor noise... not a fan chopping through air noise... cus 800rpms is very slow but i think it could possibly be a bearing noise of some kind... sorta like a scratching a very light constant scratch.... where as the yate loons have NO motor noise and undervolt like a freakin charm... yate loons FTW!

I thought the noise was an undervolting issue. If they do that normally than that's lame. I never tried mine without the rheobus.

Fan too good to be true?
