Just for reference used 2 120K ohm in paralell (same situation as you :D)and 1 4,2K ohm; no problems as of yet. The fan I built in was moving a fair bit of air through the shaft which was quite noisy compared to the original fan (the fan itself is quieter). By using some tape on the airholes of the case I managed to dampen the airstream a bit and now it's even more silent than the original fan and running just as cool.<br /><br />Anyhow, keep the good work up, this really helped. :)Christiannoreply@blogger.comtag:blogger.com,1999:blog-5065518267452559397.post-38749255325191479822009-01-20T13:43:00.000-05:002009-01-20T13:43:00.000-05:00cheers man!really nice of you.cheers man!<BR/>really nice of you.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5065518267452559397.post-30622156969567077282009-01-18T12:24:00.000-05:002009-01-18T12:24:00.000-05:00Hi somosantos:The noise level is better than the o...Hi somosantos:<BR/><BR/>The noise level is better than the original fan. But it still isn't whisper quiet. I think this is a limitation of using any small fan that has decent RPM.<BR/><BR/>The third wire is definitely the signal used to shutdown the machine if the RPM is too low. If you use a really low RPM fan, it will not work. However, if you make the circuit I show in the post, you can use any fan you want... including a fan with no third wire (which is what I did).Random Project Manhttps://www.blogger.com/profile/06669716669727996756noreply@blogger.comtag:blogger.com,1999:blog-5065518267452559397.post-3369936666567422242009-01-18T10:58:00.000-05:002009-01-18T10:58:00.000-05:00Hey RPM!Great to see someone trying the same thing...Hey RPM!<BR/><BR/>Great to see someone trying the same thing.<BR/>Can you tell me, is the noise level better by a considerable margin?<BR/><BR/>If i find a standard pc fan with a third wire, how do I know this will be OK for the dreamcast to understand. (this 3rd wire is probably the security trigger for the shutdown mechanism?)<BR/><BR/>Cheers!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5065518267452559397.post-14941405882394249232008-05-26T20:15:00.000-04:002008-05-26T20:15:00.000-04:00OOooo... nice project and nice pictures. hehe.
