    Thermal Fan-Control Circuit

    Well, if you do love your fans sounding like a jet-engine in your computer, stop reading here... Just, kidding... could need some electrical engineering help here...

    I saw this Thermal Fan-Constrol circuit at Overclockers Australia.
    But i can't seem to find that OP-Amp in any local store here in Sweden. But maybe i'm looking for the wrong kind.
    Does anyone know if there is any difference between Australian, US, Asian and European way of telling what kinda component it is and what the numbers stand for? The closest i found was this one! You see any differences with this one and the one proposed to use?

    help me out here... plz?

    The 741 op amp is VERY common, probably the first opamp that a lot of people come accross in schools, im sure you can get one in sweeden, I dont know what sort of electronic shops you have over there but any electronic shop should be able to get you one (they arnt expensive). You can get a bit more info here http://www.national.com/pf/LM/LM741.html

    Like CALV said, it is the most common OP amp there is. I have not seen an electronic shop that doesn't have them. Even Radio Shack has them.
