|  Cpu Fan I am helping a friend build a PC and the CPU Fan will not spin up when I boot up the computer. Even though you will call me crazy I booted the computer up without the fan just to see if it would work and it does. I also put in the DVD Drive and the Video Card and both seem to be fine. So if the CPU, the DVD Drive, and the Video Card all work properly why would the CPU Fan not go? P.S. I have also tried different after market fans and those don't seem to work either SOS HELP!!!!! |

| Re: Cpu Fan Yes I am there is only one 4 prong spot for the CPU fan. If you want to check the motherboard is an Asus P5LD2 R2.0 |

| We take both criticism and positive comments very positively  | Re: Cpu Fan You might have a bad fan or dead fan header. If the board does boot, boot into the BIOS and go to the PC Health screen, see if there are any auto fan settings that might make the fan not spin, or spin at a reduced speed until the CPU reaches a specific temperature.  INTEL E8400 // Gigabyte EP45 Extreme // 4GB DDR3-1600 // Palit HD 4870 // Antec 1200 // Seagate 750GB HDD // Zalman CNPS9700 // BFG ES 800W PSU |

| Re: Cpu Fan So how much time can I let the CPU process before it will burn out because keep in mind that there is no fan or heat sync on the CPU. |

| Silence..Or I kill you!  | Re: Cpu Fan Quote:
You have to have a heat sink on the CPU or it would last very long, maybe seconds!!!! As far as the fan not spinning up, you may, as was mentioned have a dead fan header on the mother board, and may have to purchase an adapter that goes from the 3 wire to a 4 wire Molex connector on the power supply.  | |

About the fan, it's probably a BIOS setting that you overlooked. E8400 DFI Blood Iron P35-T2RL 4GB G.Skill 800MHz Sapphire Radeon HD3870 512MB Silverstone DA650W WD 250GB + Seagate 320GB Last edited by Elysium; July 17th, 2007 at 17:29. | |

| Re: Cpu Fan Listen I don't have the heat sync on it because I don't have the fan on it so calm down so now with that can we focus on why for some reason everything else works on the board but not the fan |

| Re: Cpu Fan Quote:
THE CPU NEEDS SOMETHING TO DISSIPATE HEAT OR IT WILL DIE IN FRONT OF YOUR EYES IN LESS THAN 10-15 SECONDS! Do you understand now? A heatsink will at least move the heat AWAY from the CPU, meaning it will last a HELL of a lot longer with no fan. I'd say you'll have roughly 30-40 seconds with a heatsink on it but no fan. When that many people are freaking out over the same thing, there is a reason. You came to the right forum - why? Because we know what we're talking about. | |
