TomG - I'd be interested to hear more of your thoughts comparing the Panaflo and Evercool fans. In the UK I can get Evercool for £1.56, but the Panaflo is a minimum of £8.99, excl P&P! I've ordered an Evercool to try out. According to their specs, there's only 2dBA difference in it. How would you judge noise levels/quality of the two? And do you have any experience of the Panaflo 1L?

Regarding 24volt panaflo's, they will start up just fine at 5volts and up, just
spin slower. I own a number of 24H's that are happy living a 5volt life. This is in regard to the post on feb 1/2003 of this subject.

Excellent - Thanks Mike! I've been thinking about modding my Seasonic for a while but was a bit nervous about using the right fan.

Has anyone managed to find a retailer for te Panaflo 'M' in the UK? theoverclockingstore.co.uk doesn't seem to have them....

Thanks

Digikey also has Panaflo 80mm M1BX RPM-sensing fans listed in their catalog.

http://dkc3.digikey.com/PDF/T031/0974.pdf

In fact, they're the only site that comes up if you Google for fba08a12m1bx.

$10.13 each though.

At the same price, the also have
FBA06A12L1BX
FBA06A12H1BX
FBA08A12M1BX
FBA09A12L1BX (for an SLK-900? 42.7CFM @ 27dB @ 12V, might be quite nice @ 5-7V)
FBA09A12H1BX

$18.50 for FBA12G12H1BX (103.8 CFM!)

(FBLs have louvers in the body for supposedly better CFM/dB)

$13.13 for FBL08A12U1BX or FBL09A12H1BX

Shipping & handling smalll orders from Digikey tends to be $$.

Unfortunately, it looks like they are out of them. I sent an email a few weeks ago asking if they were getting more in, and I received a cryptic "Just how many are you looking for?" response. I replied that I just needed a few, and haven't heard back since.

I got a response, a shipment will be in on June 5th along with 3 and 4 pin tails. :)

I am very surprised that no one else has commented on this !! :!:

I checked out the link in his post and there was a graph showing that the above is true, but for only a given range of CFM. Looking at the graph this is about 17.5 CFM to approx 36.5 CFM. Also, they say that:
FBA fans force air out in a “funnel” type pattern,
and are ideal when cooling a specific area that is
surrounded by numerous components with
minimum ventilation available.
Leading me to believe that an FBA fan is probably the best for CPU cooling (a HSF).

However, regarding the FBL series,
Louvered design increases air flow and
decreases turbulent noise at standard
rating conditions.
Notice the word standard. Obviously, undervolting it will lower its CFM, so that will change the noise aspect of the fan, but maybe the above means that these fans make more noise regarless when running out of spec.

However, not withstanding the above, it looks like perhaps a FBL design Panaflow would be better suited for a case fan rather than an FBA, assuming it's blowing in the 17.5 CFM to 36.5 CFM range of course.

Looking at the specs, the:
120L FBA blows 68.9 CFM max
120L FBL blows 52.95 CFM max

I just ordered two 120L1A fans from Bigfoot, which I'm pretty sure are the FBA type. Since I plan of 5V the fans (and using them as case fans intake/exhaust) perhaps I would be better off with the FBL fan, but only if 5V puts it in the 17.5 CFM to 36.5 CFM range.

Anyway, I'm just inviting anyone to give any info on these FBL Panaflow fans as they sound like they could be a great resource. Anyone have any first hand experience with these things ? Anyone know the mathmatical relationship between voltage and CFM (if one exists) ?

Sorry for the novel.

Wow, that is very interesting to know Marc999. Ill keep an eye out for those FBA types.

digikey.com has a nice selection:

Also bought some Panaflo tails (see bottom of catalog page) and fan filters from them.

I tried some of the 80mm FBLs back when Silicon Acoustics carried them and they didn't seem to cool better or any more quietly than regular L1As. I was using them as case fans though, not CPU fans.

Anyone want to buy two of them?

The key here is the CFM range of 17.5 CFM to 36.5 CFM. If you were undervolting the 80mm fans, then that would place them under 17.5 CFM I would assume (I'm not sure about this).

However, 5V'ing a FBL 120mm fan may put you right in that range, and therefore may be a bit quieter than a 5V FBA 120mm Panaflow.

Nah, I wasn't undervolting them. I was comparing them at 12V. This was in a fairly hot case so I wanted more airflow than my typical 7V L1A setup would give. I was hoping the FBLs would give me 12V airflow at 7V noise levels but they didn't.

Dammit !! Just when I thought my OCD picked up on something that others may have missed. One day I will have a break through, one day !! (or maybe just a break down) :D

P.S. - Still, it may be worth trying for the 120mm Panaflows. If I decide to splurge and buy one and try it out, I'll let ya'all know how it goes. I'd probably get the Medium Flow and 5V it.

My modded Enermax uses only the inner 92mm fan. In my case, a L1A is much louder than a H1A. Since the noise comes from the motor circuit, I believe that this is most likely due to resonance of the PWM circuit in the PSU speed control with the L1A motor windings.

I know that this is an old thread.. but I just installed an old M1A into my case - 5volted it, and it clicks like CRAZY. The clicking is loud.. I guess it's just mine.

Anyone else have the same experience?

alot of new panaflo fans are made in china at a crappy factory now.

Those are known to click and stuff, it just sucks if you get one

Panaflo® DC Brushless Model FBA08A24M for $3.00. It needs 24 volts I think looking at the "24" in the model number, not the standard 12, but it seems to just have the standard 3 pin motherboard connector. Can I still use this one?
Won't it run at half speed (if it runs at all) at 12V? Hmm...I wonder how quiet it would be at 12V?
I've ordered these in the past to try them out and out of a batch of 3, none would start at 12V, FWIW.
