That looks fine. Very good. Now you just need to learn to snip
the useless portions that are not germane to the reply. In this case it would be all the lines preceded by * above. OK, I will reply through the Show-Options button from now on. I am still wondering what happened to my previous reply that doesn't show up. Jay Chan |

Thanks for the correction that you and Noozer have pointed out. I got
it backward. The higher ohm rating should mean higher resistance and the fan will run slower and supposedly quieter. No, it varies based on what fan is used. Per the same fan, the higher resistance would reduce speed more and have higher chance of failure to spin up. Per a different fan that starts out (with no resistor) having higher RPM, current, a lower valued resistor would be used than for the (unmodified) slower fan. Seem like this is one more reason to get a range of resistors instead of just one. Talking about getting a range of resistors. I cannot find any suitable resistors from RadioShack. Their selection in term of watt is very limited (1/2, 1, 5, 10 watts). I will have to order online and pay shipping. Oh well... Jay Chan |

If you're going to order, might as well get a 100 ohm potentiometer,
and adjust for the noise/cooling of your liking. Let it go full speed when you are out of the room, and much slower when you are around it. Too late for that, I have already ordered an assorted number of resistors from eBay. And I don't understand potentionmeter enough to know what to do with it. Thanks anyway. I hope someone else who reads this message may find this useful in keeping the noise of his PC down. I was quite surprised that I could only find one place (eBay) that has more than one type of 2-watt resistors that are in the range that I am looking for. Many places don't sell 2-watt any resistor. Those place that sell 2-watt resistors only sell 2-watt resistors in one ohm rating (but I need resistors in a range of ohm ratings). Jay Chan |

I didn't see any on Radio Shack's website, maybe I
overlooked them but I dug up another source, might as well get a good deal on 'em? http://www.goldmine-elec-products.co...m=2&mite m=11 Yesterday, I browsed around to look for 2-watt resistors, and I was surpised that I could only find one vendor (in eBay) that offered resistors in a range of ohm ratings. Most places don't sell any 2-watt resistors. Now, I _really_ appreciate the fact that you had spent the time in digging up a link for 2-watt resistors. That had to be quite hard. Jay Chan |
