Where the heck do I plug these in?!

OK, I go to my local radio shack and they have a huge selection of cooling fans. I know I shouldn't plug them into my A7V133 cause the power will overload the mobo. I am supposed to plug them inot my power supply. I have a Sparkle 350W PS, and I know what fan plug-in sockets look like. But where the heck on the PS do I plug the fans in? Where the heck are the fan-in-sockets! I feel like such an idiot asking.

Well, I've only seen fans come with two types of connectors. So if you're talking about fans with the little 3 pin fan connectors, then yes you should plug them into the MB. That's what the fan connectors are there for. (I've got two 80mm fans plugged into my A7V133 right now and everything is happy.) The other type of fan has the same kind of plug as a hard drive and those go on your spare PS plugs. Some even work as pass throughs so you can plug the hard drive into the fan and on into the PSU.

Pretty sure the A7V has a "bunch" of 3 pin connectors on the board. I'd go for that. 350W is plenty...

I know my PS is adequate. You are missing the point though. It is not good to have all four fan connectors on the A7V133 being used because it causes to much power to flow through the board. Instead, you are supposed to plug them directly into the PS, therefor the extra power never flows through the mobo. But where are the 4-pin fan connectors on the PS!!!!!!!!!

Ah...I hear ya. They are the same as the one for your hard drive and cd-rom. If you don't have enough then you can go and buy a Y-adapter...

Damnit! Where the hell are the fan inputs physically! Inside the PS? Under a bay somewhere?! I'm going nuts!

you have to buy a special cable silly. it has a normal ATX pwoer cable (the kind for hard drives and stuf,f) you plug it in and it has wires coming out where you plug your 3 pin connector to

It has to go into a 4-pin connector gosh darnit! Isn't there already 4-pin connectors <b>on</b> the PS!

then just plug the damn thing into a power connector for your hard drive!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The motherboard is designed for the same number of fans as it has fan headers. Fans are just about the only devices that draw 12 volt power at the motherboard so they don't interfere with anything else. Don't worry when using typical case cooling fans. The fan headers on my KT7 are good up to 0.5 amps each. A typical case fan draws like 0.2 amps.

CPU fans are another story. Some of these must be connected directly to the power supply.
March 27, 2001 1:33:08 AM

You're making this too complicated. Odds are that the fan will have a Y connector built in so you can just go with that.

There are only 2 options that I know of
1) 3 pin on motherboard
2) 4 pin using Powersupply. No special voodoo needed, uses same as harddrive for example. Don't open up the powersupply

Tempus, you OK, man? It looked like you were getting a little excited there. Did you pass out from frustration, or did you figure it out?

Summary:

If you don't have an extra 4-pin connector, go out and buy a Y-adapter. Disconnect HD, CD-ROM, or other. Attach Y-adapter. Reconnect device. Connect fan. Breathe deep, siiigghhhh.


p.s. Check fan, it may already have Y-adapter on it.

If you mean the small 4-pin connectors like on the MB, NO they are NOT on the PS. Without adapters, only the big fat HD connectors come out of the PS. BTW, why do think it's so bad to put the fans on the MB? I've never seen anyone complain about it causing problems.

Check your mobo manual or with the manufacturer for specs on your mobo's fan headers. Then look at the Delta and see how much current it requires.

Offhand, I'd say you want to connect that fan directly to the power supply.

Read my other post.

I know of a guy who uses a Delta 7k (i am getting one soon) and he uses it with the mobo connector, and it works fine, don't worry about it Wusy...

(this isn't directed at phsstpok, but rather the starter of the post... i was just too lazy to scroll up... eh)

Ignorance annoys me..

I think it was purely stated what you had to do... All you bloody need is to plug it into the mobo. i got the a7v and it works fine with all the fan plugs filled... i got 4 plugs right, F-Fan, CPU FAN, PWR Fan, and Chas Fan... and they're all filled... it's FINE

If you are using a fan that needs an external Power Source then you don't need a motherboard monitor to tell you the RPM - you'll hear it.

A7V133 = .35A for CPU fan header. Not up to most top fans nowadays.

I've read about the fan headers burning out on the mobo when using 7000rpm fans, possibly due to marginal parts?

And also directed at the poster. I haven't seen a dedicated socket coming out of the PS just for the fan. You just use one of the power connetors for the HD/FDD .... If you want to plug your fan directly into the PS and your plug doesn't match, you'll need to make one. I took a 12v fan I scrapped out another pc, cut the connector off, stripped the wire ends, soldered the wire ends and push them through the back of the connector into the yellow and black leads. Probably not the best thing to do but it works and now I have a nice big fan keeping my whopping p133@133 nice and cool.....

You can still run the sensor lead to the correct pin on the fan header. I don't know if ground has to be connected.

Imagine this is the fan header.

***
ABC

The pin at A is the sensor receiver. B is +12 volts. C is ground. (I used A,B, and C because I don't know the correct numbering, 123 or 321 but the orientation above is correct).

I'm starting to get worried. Tempus hasn't responded since that dreadfull day of trying to figure out the fan.

I hope he's allright...

Whats the diffrence between a delta fan and a normal one?

Is it just the delta has a higher cfm? noise? rpm? or is their anything special about it like it ionises the air and shoots it across... ...I'm getting a bit carried away.

What the hell r u talking about?

My question was:

Oh don't bother anymore, I just did some research and found out that delta is a fan mnufacturer, not a fan type. you were just chattin rubbish.

As you discovered, Delta is a fan manufacturer.

Usually, however, when someone mentions "the Delta" they are talking about the 60mm model that spins at 7000 RPM, moves 38 cfm of air and generates something like 46 dB of noise.

Other premium CPU fans are slower and quieter and they average between 23 to 33 cfm.

Hope that helps.
March 29, 2001 6:51:06 PM

Sorry, I don't own a Delta so I don't know what connector it has. I think it depends on the supplier and connector type is optional.

Read the current rating for the fan and make sure it doesn't exceed the capabilities of your fan header. I think someone mentioned 0.35 amp, max, for the headers on the A7V133. (Please double check this. Don't take my word for it).
March 30, 2001 7:07:29 AM

Wusy, I didn't know that. Should I stand in the corner or what? :)

Wusy, You certainly seem to be disturbed. It must be a combination of your nymphomaniac mind and your sexually challanged body. Maybe that will calm your hormones down. In my previous posts you even failed to answer my simple question. That should indicate where the stupidity lies. Now you're expressing 'your' knowledge after everybody's already pointed out the facts.

People post here when they require help, are able to provide help or to exchange information. You just post rubbish. Any help you do seem to provide is just a repeat of what someone else posted. Such obtuse behaviour can lead e to one conclusion, and it is your life. This is all you seem to do. Go get a life.

You're answer was it needs more power!

Thats correct as a statement but not as the answer to my question.

I do however forget that not everyone here properly understands English. I'm willing to let this one go.
