Antec truepower fan connecters

[Armageddon415]

How many fans can I plug in per connecter for the fan only plugs?

 

[FlowerMan]

Just like any other power connector from the power supply: as much as it can handle (wattage wise). I wouldn't recommend using the fan only connector, as it is often too slow.

Don't know the wattage, but Antec says no more than 2 fans connected. Some of the literature with earlier TruePower's didn't say that but now it says it with the in-box literature as well as on their website.

The cool thing about the fan connector is that if you were going to add a resistor or rheostat to control a couple of your LOUD fans, you no longer have to do the mod (unless you don't like the way the fans are controlled by the PS). I'm running my exhaust fans (2 80mms) off normal power connectors and 1 120mm intake off the fan-only connector. The 120mm (Sunon 108cfm) at 12V is quite loud, so this worked out pretty well for me. Wish I had the antec PS before I cut up my case for rheostats!

Actually,it's no more than 3 case fans connected to the Fan only connectors.I just purchased an Antec 1080B case that comes with the Antec True 430 watt power supply.Should be here tomorrow or Monday.I don't know the reason for using 3 case fans on the 2 plugs.

 

[Armageddon415]

So is it 3 fans per plug or 3 fans for both plugs? If its for both plugs, that makes no sense. Can one handle more wattage then the other or something?

 

[FlowerMan]

I just contacted an Antec rep that I know. I'll update you guys ASAP

 

[FlowerMan]

Seems my comment above was incorrect Here's the reply from the Antec rep:

We recommend only 3 fans on the fan only connectors. This is likely conservative, and comes about for fear of how much fans draw when they lock
up (quite a bit more then when they're running).

For example, on the Antec 1080B Truepower 430W p/s... The website says you should use 3 fans for the fan-only connectors... Like what LastRide said. However, on the case, there are 2 more slots behind the front bezel for 2x fans. Where do you hook these up to? The mobo?

 

[FlowerMan]

Just hook them up to the regular 4-pin molex connectors... why do you feel the compulsive need to ONLY use the fan only headers?

 

[progex]

So, is it safe to hook up 5x 80mm fans to a 430W TruePower P/S?

... Even though the specs. of the PSU is to only hold up to 3x fans?

 

[Blayze]

I don't see why not Im running 4 fans on a Antec 300 watt

 

[FlowerMan]

Goddamn it, the True Power series has a "FAN ONLY" connector that can control the fans' speeds according to the temperature the PS reads. It's like the temp sensing fan in the PS, only now you can control up to 3 fans as per the manufacturer's suggestion.

Of course you can power many more fans on the regulat 12V+ and GND lines.

 

[VTrider]

Whoa! Everybody calm down Flowerman's right though. I have that Antec Truepower 430 p.s w/that special 'fan only' molex connector. Doesn't mean you 'have' to connect the fans 'only' to this, just give the extra goodies - lower voltage?, runs off the thermal control sensor in the p.s or something.

I have a 92mm case fan connected to it, runs it nice and quiet - it would be a little louder if I just connected it to a regular molex connector. I also have 2 80mm case fans connected to it also - 3 total, like Antec recommends (max).

[AntecCSR]

The 'Fan only' connectors are just for fans, nothing else. And yes we state the limit on 3 for safety concerns.

This doesn't limit the number of fans you can run off the psu, my home system has 4 fans running of a True430. We also state in the manual that you can connect fans to the normal molex connectors but these will not be controlled by Antec Low Noise Technology.

Guess that settles that! :Q

ANTEC CSR:

Provided Y tech comes out with an 80mm version of those tip driven fans to use as case fans, couldn't all FIVE of those (like in a 1080B) be hooked up to the fan only connectors? If your concern is on a fan locking up and drawing too much current, it's my understanding that these type of fans pulse if they lock, thus don't hit with a huge current draw (turn themselves on and off). Then, all the case fans could be controlled through the power supply.

Sound reasonable???

Maybe something to look at when the 80 mm version of that type of fan is released.

 

[VTrider]

Although I have 3 fans connected to the 'fan only' connectors (2x80mm, 1x92mm)..........

I've noticed that when I connect more devices on the power supply, such as my cold cathode light - 1 and sometimes both 80mm fans 'pulse' on startup/boot. They remind me of a car engine trying to turn over in cold weather! This I imagine is from the additional power draw which is I guess obviously enough to weaken the current going to the 'fan only' connectors.

I have a Antec TruePower 430 p.s, I don't have any crazy setup sucking the power from it, and quite frankly....i'm a little dissapointed that it seems as if this p.s is already breaking a sweat trying to send the right voltage to everything when turned on.

I still like it, I still recommend it, it's quiet, moves a lot of hot air (which I think a good majority is generated inside the p.s itself).

[AntecCSR]

I don't know about the TMD fans, it's something product devolpment will have to test.

Also I have no idea how much power cathode's pull so I can't answer that either.

VTrider, my guess would be that, when you turn your system on, the thermal regulator in the PSU is relatively cool and so the voltage to the "fan-only" connectors will be at its lowest. If your fans aren't fairly good, they may have a hard time getting rolling at low voltages and this would explain their difficulties. The stock Antec case fans are sleeve-bearing fans, as far as I know. You might try a drop of TriFlow oil on their bearings (peel label off to access it).

Then again, you said this only occurs when your cold cathode is plugged in?

 

[VTrider]

Yeah, that makes sense. They're Panaflos L1As, sleeve bearing. It's not really a problem, they sometimes do it, sometimes dont' - and it's only for a second or two then they all fire up and stay spinning. I'm pretty sure if I unplug the cold cathode light, it won't do this. I guess i'm just suprised, I used to run 300 watt p.s w/tons of stuff connected and never had that prob.

I'm sure that if I connected those fans to the regular molex connectors, they wouldn't experience this intermitent cold start pulse thing, but it's all good anyway.

I have a truepower 550 and now I only have hooked in the two noisy slot coolers. Keeps em nice and quiet.
When I first got the power supply I plugged most of the fans into it. Bad idea. Case heated up REAL quick.

 

[gizbug]

Thanks for the information

 

[LuckyStrike]

Anyone know what the temp should be for the Antec sensor to start the fan only connector?

I have a silencer fan hooked up to a true power 330 and the sucker has never run unless you jump start it.

This power supply is quiet but if you stop all the fans any power supply would be

[AntecCSR]

If the Silencer is a 'smart' type fan (variable speed, temp sensor etc) it likely won't work with the fan only connectors. We've been able to get a couple to work but in general we've found that it's not a good idea.
