What about these Panaflo's?

Yes there is a ton of noise difference between the Panaflo's and the others... The Panaflo's hit 35-36 dB's which sounds like a mini vacuum cleaner in your computer, but they can really get air moving with 86.5 CFM. If noise is absolutely not a problem then those would be very good, but if noise is in consideration, your best bet is probably the Scythe with 28 dB's and 63 CFM (which is pretty quiet and still moves a lot of air).

Edit: grammar 😉
 
Panaflo M1A makes alot of noise at full speed but moves alot of noise..even if I undervolt to 7v..noise is worse then my Pamaflo L1A @12v(69cfm)...it is the motor noise that is the issue for me..whine just sucks..I run my Panaflos L1A 7v..close to YL@12v and moves more air with better static pressue

Please note specs are very subjective and few manufacturers are real good on being honest

Yate Loon are pretty accurate on noise and CFM combos, the panaflos are pretty accurate too

Scythe with 28 dB's and 63 CFM ..I do not have one of these but I doubt they are getting 63cfm@28dba..this is the noise a YL makes at 47cfm

YL makes a 140mm fan that will move like 67cfm @28dba but you can not get them in the USA..cost about $30 from Europe
 
I run two Panaflo M1A 120mm fans at 7V. Noise is audible, but not objectionable - flow rate is good (50 CFM estimate).

Note that these are 38mm thickness, and some modding may be required to mount them in your case.

Hope this helps!

But one is 28 and the other 36? Doesn't sound like much difference. I have the stock thermaltakes tsunami, and the web site says they are 21db. I can hear them pretty good, so I was kinda worried about the 28s, then someone said thermaltake is lying.

Actually, there is a noticible difference between 28dBa nd 36dBa, although once installed in your system the difference will be harder to tell. Are you going to be running your fans at full speed or are you going to undervolt? Some fans (albeit usually high-flow models) don't like being undervolted and sometimes complain (don't like to spin-up or make noise) when they are undervolted.

If you are sure that you don't/won't need to run at full speed and plan on undervolting why not save yourself the trouble and run a more quiet fan with less CFM to begin with? I have no experience with the 28dBA/63.7CFM (SFF21F) Scythe fan Criscross3234 mentioned (I wish it had a speed-sensing rotor) but I've used the low-flow Panaflo L1BX (30dBA/68.9CFM) and was pleased with the flow/noise ratio. Heres a link to the L1BX at FrozenCPU.com:http://www.frozencpu.com/fan-225.html

I was running a SI-120/120mm L1BX before I discovered that the sweetspot for airflow in my current configuration is around 50CFM, so no point in running the L1BX at full speed and noise when it doesn't help much, even under load (After my BIOS update to 0404 on my A8R32-MVP Q-Fan no longer works at all on my system so fans fun at full speed all the time). This is how I discovered that I didn't need all the airflow of full speed. I verified the results by testing at lower fan speeds using Speed Fan. If you are not familiar with Speed Fan and/or you don't have it yet get it here: http://downloads.guru3d.com/download.php?det=893

I am running 120mm Stealths' (28dBA/53CFM/<1500RPM) on both my CPU and for the (front) intake on my V1000 case and will continue to do so at least until a later BIOS fixes the Q-Fan issue. I run the fans' off the mobo headers so that the fan speeds are both monitored and temperature controlled by the system. The Stealth is 120mmx120mmx25mm and so is the Scythe SFF21F, which has better performance specs (28dBA/63.7CFM@1600RPM) but it doesn't feature RPM-monitoring or else I would have gone with the SFF21F. Are you listening Scythe?

BTW, theorietically each additional fan you add to your system only increases the dBA by 3(dBA) over the loudest component in your system. The total dBA is cummulative, not totalitative.

So, theorietically, if a Panaflo M1-BX is the loudest component in a system, the three (3) Panaflo M1-BX fans equal 92.5dBA (86.5dBA + 3dBA + 3dBA = 92.5dBA). But the noise from other components still has to be factored in. Someone please correct me if I am wrong. Be nice though.
 
I bought the Scythe F model, runs at 1577 max (thought they ran at 1620? no obstruction only?) and they are very quiet. I could put up with more noise so maybe the panflo would have been ok. I think I should buy another scythe for the exhaust, or accelero exhuast, not sure. What do you guys think?

? anyone know why I get the 1577 rpm max?
