Fan and Coin Door Light Question

[NickS]

Hello,

Just a quick couple of questions.

Is it possible to power 2 fans from the 3 pin motherboard fan connector?. Will there be a significant reduction in the speed?. Would I be better powering them directly from the power supply?.

I have a single entry coin door which requires one bulb. Someone suggested to me that using the power switch led was a good way to go. He suggested that I cut the two wires just before they reach the led and attach them to the two connectors on my coin door bulb. Does this sound feasible?.

Your opinions will as always be greatly appreciated.

Is it possible to power 2 fans from the 3 pin motherboard fan connector?.

It may be possible, but not recommended.  If the combined load is to high you could burn out the header.  In fact  there are some fans(mainly larger 120mm) by themselves that draw to much current for the MB fan headers.  Not worth the risk IMHO.  

Would I be better powering them directly from the power supply?.

Absolutely.  The powersupply lines are much better suited to this.

As for you other question i'm not quite sure i'm reading it correctly so i'll let someone else field it.

This sounds like you want to cut the wires going to the LED and reroute them to your coin door bulb.  NO NO  it will seriously overload the led power light header from your MB.    Use a drive power connector to get the 12V needed for a light or 5V in the case of a 6V light.   Attaching any light to a MB header is a bad idea.

Read other threads about using a high brightness led for the coin door.  Some are even made to replace the coin door light bulb.

Thanks for your replies.

I will run the 2 fans for the cabinet directly from the power supply.

As regards the using the power led for the coin door I have obviously been misinformed. Do you know what voltage the power leds are ?. I will check out the super bright leds. I have been trying to find previous posts on connecting the coin door light to the pc power supplies but without much success.

The FAQ is the best place to look for something as common as this.  Or use the search feature of the forum.  Not to be mean, but you couldn't have looked too hard.

Here is a direct link to the section in the FAQ document:

If you didn't know where to find it, the FAQ is the second post in the main forum (at least for now).

Thanks for the link. I did a search using search facility at the top of the message board and I did not get any posts earlier than August 2003. Even using the advanced search.
