| 286160 | 2004-10-30 01:44:00 | I stumbled on this just yesterday, and it works a charm. I was thinking, with all this fan speed control and whatnot, why not just wire the fan so it constantly gets the full 12V? So, I got this little lead I found (probably get it from DSE for like $10), which plugged into one of those 4-pin molex hard drive power plugs, and went to a socket you could plug a standard CPU fan into. I plugged the fan into this instead of the motherboard, disabled all the beeping fan speed alarms, and hey presto. Before, my average temperature was 40 degrees (Cel D 2.4 OC'd up to 3.09GHZ) Now, it has dropped down to 31 degrees and I can hardly notice a change in noise. True, I can't monitor my fan speed anymore but it's worth it I would say. George |

| 286163 | 2004-10-30 02:42:00 | Graham L, Bit like direct physical connect, capilary, manuall off type: Oil , Temp, Boost, Vacume, Gauges . And a simple direct cable Volt/Amp Meter . All manuall gauges . To simple . Not allowed . Anybody can see what's Wrong and fix it, in a swamp, or somewhere like that, easily . Cheaply . And Quickly . D . |

If you haven't got this you haven't got the proper level of unreliability. What on earth are you on about. It seems to me that you have grossly misunderstood what I was trying to say. What I am talking about has nothing to do with displaying any incorrect figures, or tricking the computer into beleiving them. In a normal PC, the 3-wire fan lead plugs into the motherboard. One wire is ground, one is +12V, one is 'sense'. This tells the motherboard the RPM of the fan. In accordance with the temperature, the +12V line on the fan is altered to make the fan either go faster or slower. The maximum speed is of course continuous 12V. At a given time, for example, there may be 10V across the fan, equating to an 83% fan speed. My cooling method is to increase the RPM of the fan to 100% at all times, by having the fan, instead of plugged into the motherboard, connected directly to the power supply, meaning that at all times it receives 12V. There are two drawbacks to this. One is that the PC will be slightly noisier. I noticed very little difference personally, but that depends on your fan. The second is that you will no longer be able to monitor the speed of the fan using software or the BIOS, because the 'sense' lead is no longer connected to the motherboard. Everyone understand now?

| 286166 | 2004-10-30 03:30:00 | Of course we all understand. One or two were just trying to be smart. Your fan may wear out sooner than expected though. Jack |
