Modding New to this all...need help...plese help

im new to all this. im buying a premoded case.. i know shame on me. but my questions is about fans and LED's. i will have a total of 3 fans and some led's. i have a 350 psu and amd xp 1600. will i need a bigger PSU or do i need something to vary the fans.. help.. i dont know what im trying to say... i dont want to fry anything so what must i do to avoid doing so.. point me in the right direction...

thanks to all... msn messenger... s7e7e7n@hotmail.com

 

A 350 watt PSU can handle 3 fans on high, no prob (LEDs included).

 

got a 300 and got the whole computer (xp 1.47, mobo, dvd, cdrw, 4 pci, 2 hdds, 80mm cpu fan) + 2 cathode + 2 80mm fans + EL cable and everything is fine

 

Can anyone explain the rheobus, whats all that for or when do you use it.. or is it mainly looks

 

Welcome to the boards.

Ah, the rheobus. Well, you probablyknow that those AMD chips run rather hot. So the reaction is to insert fans (lots of them typically) into your case, improving (we hope) airflow and temps. But at the expense of noise. If you go out and get the most hellacious fans you can find, they do move serious air. And they're loud.

So at somepoint, some wise guy figured out that lowering the voltage to the fans would slow them down, and quiet them down, and they would still cool okay. And sometimes (gaming, ovrclocking) you need more flow, and othertimes (sleeping) you need quiet.

So that's what a rheobus does, it lowers the voltage to the fan, and slows it down. It's just one of your alternatives that accomplish the same effect.

 

thanks.. nice to see a board that actually replies.
anyone got some good ideas for some first timer mods.. im going to stealth the cd-rom and floppy.. posiably change a led on the floppy and cd-rom. anyone have good links for those..

 

A rheobus is a fan speed controller that uses potentiometers and voltage regulators to adjust fan speed.

edit: didn't reply fast enough

 

just desolder the leds and replace

 

ohh.. one other thing how would i go about doing this.. shining some light on the subject.

about half way down.. where he is shining the flash light on there.. also where is some good switches.. to turn these things on and off..

 

how would i power the LED's

 

You'd get that effect by placing LEDs in/on the edge of the plexy.
You can power the LEDs off a 5v line from a molex (if you have 5v LEDs) w/ the proper resistor.

Edit: Also, for your power supply question...

first time advise eh?? Prepared to spend a lot of money

 

Heh. It is an expensive habit...er....addiction...er...hobby!

 

LoL, expensive.... For a while, you should add up all of the prices of the mods you are planning to do, and then... double it! Yes, screwing up tends to happen alot at first... you slowly begin to screw up less. That is at least my personal experience....

Have fun

 

Yeah I found that happened to me quite a lot You think something is going to be simple and then you manage to find ways of screwing it up
