There's only one requirement, it must be able to use molex connectors, or i suppose screw terminals, where i could just chop off the molex conectors from the fan. Oh yeah, and it must be from a retailer in the UK. You are thanked.
Just build one, probablly cheaper and you can do whatever you want I'm sure if you search you'll find some guides and schematics
Go to http://www.maxoverclocking.com/ele_esq1.html there u have all the types of fan controller available and how to do them (its in spanish though, but with the schematics u get the idea ) Or u can just buy a common prebuild one, in the Uk im sure they re cheap.
Make it, Itd only cost a couple quid at most from maplin .. Simply done and you got lots of options on styles etc
Anyone notice that those images are taken (possibly stolen) from bit-tech.net?? In the fan controler article.
Some of them are taken from bittech, its said in the site. The author didnt put those schmematics as they were his its just to show how to made them.
if you want to buy one made, i reccommend the zalman one - ive got one and it doesnt hiccup with all the fans i have on it. 4 rheos- 1=70mm cpu fan 2=120mm intake 3= 2x80mm intake 4=2x80mm exhaust 2 5v/off/12v switches 1= 2x80mm antec green led fans 2= dual 9" green neon inverter the only fiddly bit is the fact that the 2 switches require bare leads. and the led's only work on the rheos if you have 3wire fans - the rpm wire powers the led, and they get brighter (actually, flash faster) as the fan speeds up.
you know, I think I might actually pull my finger out and build my own. i'll post some pictograms once i'm finished!
I have a question. What do you lot think about having flashing led's as opposed to normal LED's? Might give it a bit of a "Wargames" look. The bay in which these will be going is 15cm across, so i'll be using 7 led's, with 7 switches under each. The switches are going to make or brake a connection to a screw terminal, to which i will have the fan connected. What do you think?
