Anyone Using "Fan Only" Connectors on Their Antec Power Supply?

I'm wondering what speeds you're getting when you connect your fans to the "Fan Only" connectors on your Antec power supply? I've got my 120mm Antec fan connected there, and speed never goes above 800 RPMs. Unfortunately, this doesn't move practically any air. Is this a normal RPM for that connection?
 
I tried it, but it's like they're only set to 7V; I'm not bothering with them at all.
This is an Antec Truepower 430.

Same here... too slow for my liking
 
my 80mm's have sat pernamently at 1440rpm (er, thats not necessarily true btw, theyre both 2-pin fans and i only have the pin from the psu being measured, so im assuming theyre at the same speed as whatever the psu-line is monitoring - i can see theyre spinning noticably slower when the case is open).

this is actually fine for me as i have two intake and two exhaust medium-speed fans - one of each connected to the fan cable. Would not want to have them connected if I only had the two fans though.
 
I have 6 case fans and Decided to try the FAN ONLY connector for the two exhaust fans. They do spin slower (probably a 7 volt mod -- that's why they said ONLY use a maximum of 3 fans on the connectors). But after I connect the two exhaust fans on there, The temperature went up by 1C, but it was a lot quieter 🙂

I have the 550w True Control so when I connect my fans to the Fan Only connector I can manually adjust how fast or slow it goes with the potentiometer but when I do that the Power Supply fans also speed up and slow down.
 
I''ve checked the voltage on several sets of the Antec "Fan Only" connectors by using a multimeter. It ranges from a low of 4.8-5.2V to a high of 11V. It's pretty hard to get it hot enough to increase the voltage so the typical operating voltage on the "Fan Only" connectors is right at 5V.
 
I'm using it on my antec plusview case's exhausts. If I had more panaflos I wouldn't use it but it works well for quieting down the included fans. It's a nice feature for peace of mind, but its usefulness depends on your fan setup..
 
I'm getting this case Thursday or Friday along with the rest of my system... I can't wait! Bah! The pain of waiting.... I can't study 150 words and definitions plus all their roots while thinking about my new computer coming with the Sonata and its nice PSU....

I hope the Sonata lives up to my expectatios for being quiet and regulates fan speeds nicely....

Also, does the PSU slowly adjust the fan speed or does it jump around like from 1000rpm to 1500rpm (just example...) or does it go gradually like 1000 to 1050 to 1100 and so on till the temps stabilize?

I ran out of those, and I don't feel like digging for those Y-splitters 😛

You ran out of connectors? :Q That's an accomplishment, even when I had three hard drives in my case I had several extra....

😕
 
i'm soooo glad this topic was posted. i put my smart fan II in a regular PSU connector, ran the fan @ 4600 rpm and now i can run my 1700+ @ 200*11.5 @ 1.6V idle temps @ 37C (if you guys really want to know how inaccurate temp readings on mobos are, my CPU runs @ 32C @ 1.5V which is less than room temp 🙂)
 
I use them, and wish there were more, as there is no reason to go crazy about the temps I have (max 36C case, 52C processor). As long as you get good temps, RPM should not matter AT ALL.
 
I have a True480, and I bought a Vantec Tornado to use on the "fan only" connector. The fan has specially anged fins and moves more air per RPM than any 80 mm fan on the market. I now have my Tornado spinning at 2500 PRM, and it keeps my CPU as cool as old fan spinning full blast at 4,000 RPM, and it is a good bit quieter. The "fan only" connector was actually a great selling point for me.
 
sorry to seem ignorant, but i am new to this. i want to get either a sonata or slk3700 and want to put 120 mm fans (which i don't have a clue yet), but do i want to hook them up to the fan only connector? and what would happen if i used a fortron 120mm psu as opposed to the 380 TruPower in the Sonata. are there different types of connectors on the fortron? thanks for the help.

the 380W truepower is a great PSU and should not be parted out for a fortron (although fortron is good too). the 120mm fans will basically run as if they were 5V fans and thus get less RPM
 
although a bit off topic, so you would say to stick w/ the sonata w/ the stock PSU. I could get an antec slk3700 w/ a TruPower 380 if it were better.

Excellent thread by KenAF Should answer some questions.

Speaking from my experience with the Sonata; The Sonata is very very quiet (not silent). The only thing I can hear is the sound of air comming out the psu, but it isn't really annoying, and I have to concentrate to hear it.

You could get the SLK3700. Point is that the Truepower comming with the Sonata only has one fan, AFAIK the "normal" Truepower series has two fans.

Another option would be to get the SLK3700 with the Fortron 120mm psu. Don't know how this would fare.

Do a search in cases&cooling on Sonata and you most of your questions should be answered.

Edit: Since I'm such a nice guy I dug some of them up for you. You can also find link to reviews at antec.com

Mine raises slowly to about 1500rpm when I turn it on (cold boot). Takes a couple of minutes I think.

Here some guy has a rpm:temp guide. Don't know if it's any good though. Seems a little bit fishy. Right now my case temp should be 33C, and the fans spin at 1500rpm (measured with PCAlert4 on MSI mobo). They do say in the thread that the temp sensor is inside the psu, so maybe that's why.
