Just got my Panflow L1A fans in the mail...

Hey all,

After debating to ditch my 80mm Adda case fans (see this thread) with larger fans and a shroud to keep the noise down, I instead decided to pick up a trio of 80mm Panflow L1A replacement fans.

The units aren't bad. They are much quieter than my old Addas and yet they move a decent amount of air. They also come with a detachable power connector, so you can switch between a 3-to-3 pin cable or a 3-to-4 pin molex cable without replacing the fan.

The only issue I encountered was when I tried to unvolt them. I found that when I hooked them up to my new "Noise Isolator VR Fan Speed Controller" unit, the fans began to make an oscillating buzz. I thought perhaps it was just two fans side-by-side running at slightly different RPMs, so I disconnected all but one fan. No beef. Seems that running the 80mm L1A fans at ~10.5VDC or lower is a bad thing.

Just my 5 cents...
 
I found they tend to make a bit of noise when adjusted with certain fan controllers. When hooked to a fanbus with switches, there are no issues.
 
I received my 80mm fans from Jab-Tech for $6/each. New-Egg wanted a bit more for them (and charges more for shipping), otherwise I would have gotten them from there.

I also played with the fans a bit and found that the oscillating buzz disappeared when I connected them to one of my ABit's 3-pin fan headers. Even when undervolting them to 8VDC (the lowest the ABit supports), they were quiet as can be. As such, I think the fans may not like undervolting with some fan controllers. Oh well, the blue dials still look neat and match my blue power LED perfectly.
 
I only have a single Panaflo 120mm M1A in my case and it undervolts wonderfully. It actually makes some wierd bearing noise at 12v but when I go lower the noise pretty much disapears, even down to 7v. This was the same case with my 92mm M1A that is now collecting dust in one of my parts boxes. Now, it should be noted both of these are M1A, not L1A and they are 92 and 120mm, not 80.

However, I have heard that the 80mm are supposed to be better as you have a much better chance of getting a made in Japan one. You may have a bad batch or these are just the "new" Panaflos which is why websites are saying buying them is becoming a crap shoot due to varying quality.

Wow, 10 Panaflows for $26.50 + S/H. Thanks exitous!
Should I worry that these are 2 pins intead of 3? It'll still work if I plug it in my mobo, correct?
I need these to replace the fans in my case. Especially the fans of the PSU. It sounds like a Hoover vacuum from 5ft away.
 
The last time I bought 10 Panaflo's, they came with a two pin connector pigtail that plugs into the FAN (not the motherboard). This leaves two bare wires for you to connect to the plug from your old fan...

Didn't you notice when you added the fans to the cart, that they tried to sell you 3-pin and 4-pin adapters?

You can get fan tails. Or you can do what i did and just chop the notches off the connectors and leave one pin open 😛

The buzzing might be do to the Chinese version or you simply your fan controller is having issues. I have 4 80mm Panaflo 12L's and they are all at ~1/3 speed nonstop. I also have a 92mm Panaflo 12L for my CPU fan and that is also at ~1/3. My CPU under full load is 45C (2500+ @ 2000mhz), and my case temp never rises above 20C.

Very nice fans, Panaflos are 😛

I haven't bought them yet. I'm going to browse through their website to see what other good stuff they have. Thanks for the infos.

Exitous, again, thanks for the link.
 
Panaflo fans don't like PWM fan controllers. If you use good old voltage regulators, they should be OK down to about 5v to start, and even below 5v once running.
 
Alas, my fan controller was a Rheobus PWM. If Panflows don't like 'em, that explains the noise. I'm debating if I should send it back or not. Doesn't do me any good as a fan controller, but it does make for a nice piece of eye candy since it matches my Lian-Li blue power LED perfectly.

I ended up hooking all three fans to my ABit's Northbridge fan header since it was available (switched to a Zalman passive long ago). The BIOS can automatically adjust the voltage between 8VDC and 12VDC according to the case temperature, so typically they are very quiet. The low 0.82W power draw of the fans is also low enough that I'm not worried about blowing my fan header with the fans connected in parallel.
 
ABit rates their fan headers up to maximum of 6W (0.5A @ 12VDC). At full speed my three Panaflo L1As pull a combined power draw of no more than 2.5W (0.21A @ 12VDC).

Technically I could run seven Panaflo L1As or three Adda AD0812MB-A76GLs off the same header and still be under the maximum. The bigger question is if that 6W rating is just a conservative number or if that truely is the limit. I personally treat it as a real maximum and never plan to push it past 4W.
 
I just bought a couple myself. They dont work when i plug them into the mobo. Do i have to enable Q-fan in the bios or buy a molex adaptor for the power supply?

Which fans did you buy? The only Panaflo fans that JabTech sells that have the RPM-monitoring featureare the 92mm low flow (FBA09A12L1BX): http://www.jab-tech.com/customer/product.php?productid=2608&cat=80&page=1, and the high-flow 92mm: http://www.jab-tech.com/customer/product.php?productid=2001&cat=80&page=1

They do not carry a 92mm medium output fan with RPM sensing. To be able to sense RPM, RPM-monitoring fans use a rotor with a tach feature built-in. You cannot add the RPM sensor to a fan, it has to be built-in to the fan circuitry. (Installing a 3-pin wire lead to a fan that does not have an RPM-sensing rotor WILL NOT turn the fan into a RPM-monitoring/sensing unit).

I haven't not seen any 120mm Panaflos' with the RPM-monitoring feature at JabTech, but Panaflo does customize features for OEM suppliers. If you search the net' maybe you'll get REALLY lucky and find some, but IMHO that would be the greatest stroke of luck. Better chances of winning the lottery.

And, even if you bought rpm-monitoring fans if you didn't order the 3-pin fantail the RPM-monitoring feature will not work. Better check what fans you bought. If you bought RPM-monitoring fans and didn't buy the 3-pin fantails you just need the fantails. If you bought non RPM-monitoring fans you are out of luck, unless you exchange them.

Finally, its' been a long time since I messed with Q-Fan on my P4C800-E Deluxes' or my A8V Deluxe, but if I remember correctly you SHOULD NOT need to enable Q-Fan in the BIOS. Once you connect the correct fantail to the mobo's CPU FAN header the RPM-monitoring function should work. Q-Fan just controls the fan speed ratio.

This is the fan I bought http://www.coolerguys.com/840556001041.html I just recently bought 2 3 pin to molex connectors to connect to my powersupply. Connected and everthing, but refuses to turn on. I dont know if these 2 fans are broken or Im just missing something.

Zeppelin2282,

Looks llike you are out of luck on the RPM-monitoring for your 80mm Panaflos. The 21dBA, 1900 RPM, 24CFM L1Bs don't support RPM-monitoring. Maybe you can return them for the H1BX that does support RPM-monitoring. Cooler Guys sells it:

http://www.coolerguys.com/840556001065.html

Its 32dBA instead of the whisper-quiet 21dBA of your L1Bs, but it supports the RPM sensing you want and also flows more air (39CFM at 2950RPM). It also has the 3-pin fantail to plug directly into the CPU and case fan headers on your mobo.

The thing is though is that it also came with the 3 pin fantail cable and then i plugged that into a 3 pin to molex cable, which didnt turn the fan on at all. I could care less about rpm monitoring, all i want is for it to start blowing air haha. Thanks man for all the help too!
 
Anyone know of 92mm or 120mm fan suppliers that sell the new 4 pin (PWM) fans which are to connect to a 4 pin header on the new 925X mother boards?

These 4 Pin(PWM) get their speed control via the chipset rather than using a thermal
chip on the fan itself as in the 3 pin models.
