They're pretty awesome fans actually. With my "smartcooling" enabled through the BIOS, they almost never go above 2000 RPM, at that speed they're pretty quiet. Quieter than my 4870's @ 50%.Originally Posted by mbudden;11668085
Interesting. These go for anywhere around 8-15$ on eBay.
If you have any sort of PWM control through your board, you wont even need a controller. Simply wire them up correctly and let your board adjust them automatically.Originally Posted by Dr.X;11668342
Yeah I'm going to rewire my Nidecs from dell five pin to 3-pin for use with a fan controller.
Interesting. I do have an old Dell fan in my closet somewhere. I know it uses a proprietary connector. You said it stays below 2000RPM? What's the speed on them? Looks like I need to do some purchasing, and buying a fan controller lol.Originally Posted by BlackOmega;11669495

And this doesn't only apply to that particular fan, but any proprietary Dell fan. From the research I did, it seems they wire most of them this way.
They're 3900RPM fans. Even at full speed they're not all that loud really. Quieter than my old 92mmx38 Tornado (IIRC, 120CFM @ 6000RPM).Originally Posted by mbudden;11669545

Sub'd I have a bunch of dell fan's and actually was going to test them (about 12 80x38mm Nidec/delta fans) Good thing you posted this so now I don't get raged when they don't work.
Depending on your board, a lot of them can control up to about 4 fans. My board can control 3 I believe. It's just a matter of fine tuning the temps at which you want them to ramp the speed up.Originally Posted by Dr.X;11669641
I'm not getting the controller only for the Nedics.http://www.overclock.net/air-cooling/889733-fan-system-planed.html
Well, it does say specifically that it's from a server. Although the pinouts are exactly the same as Dimension desktops.Originally Posted by trueg50;11670281
Pretty well known, but is also a very very bad idea; those fans exceed standard fan header specs and can lead to a damaged board or components. You should be powering those fans off a molex connector straight to your PSU. That will also give you the opportunity to use the 7 or 5 volt settings instead of the full 12 volts.
Also, that isn't a Dell proprietary connector, it is a Dell model specific one, and varies very heavily from one server model to another.
It is something like 1/2-1 amp I believe, but it depends on the board.Originally Posted by BlackOmega;11670463

I couldn't find any definitive information about how much amperage the fan headers are allowed to pull, if you have links on the subject, that would be more helpful than "they exceed fan header specs".
I've looked all over for any sort of definitive specs about current draw, but other than some forum posts, nothing that actually states a concrete specification.Originally Posted by trueg50;11670847

On my old Asus X38 board I used to run one fan just fine without issues; however when my roommate tried a similar fan on his MSI board it toasted one of his sticks of RAM. Litterally his system just powered down after running for a while; and it kept blue screening, so we ran memtest and moved sticks around and one stick was good and dead.
You surely could, I've used several fans in the past that have had that setup.....Although, they didn't seem to have anywhere close to the same current draw.Originally Posted by Dr.X;11672873
You can wire the power to a molex and the control and sensor to the board.
They are only 1.6 amps according to the sticker on them. I have some 92x38mm Nidec Beta V fans (from Dell servers) that draw 3.5 amps that I have ran off of a crappy motherboard (even did two of them on a single header) and nothing ever blew up. I don't recommend pulling 7 amps from one fan header but that delta would be fine on a fan header.Originally Posted by trueg50;11670281

NICE!Originally Posted by Nytesnypr;11676036
Well after I read this earlier today , I just happend to gave one on hand. Chsnged the pins around and added it as an extra exhuast fan. It's Currently running at 4000 rpm running off my board and moving some serious air. It didn't come out of a server, it came out of an old XPS system I had lying around. Dropped the temps 3-4 degrees C on everything in the case. Cpu is down 4, NB is down 3. I do have some adapters to slow the fan down if need be. The Label says .55 A , so it shouldn't be a problem.
Holy CRAP! 7.0A on one header!Originally Posted by mrfajita;11676094

How do you get them that low? Mine were 42c at idle,moved my gpu down a couple of slots and put a AeroCool Shark on the side panel Blowing on the board and it came down to 39c, now it's at 36c with the Dell fan sucking the air out. Cpu is at 30c. I ran LinX for about an hour, Nb Temp never went over 45c, Cpu hit 48 once or twice.Originally Posted by BlackOmega;11676307
Although, having NB/MOSFET temps below 30C is always nice.

And the bad thing about the Dell fan is When I decide to go crossfire, It has to come out.Or get a bigger case...The wife would Love that...lol
