That's clearly a moving part, probably a fan. I'm surprised it doesn't last longer. It's not lasting longer (yet) because you're only hearing it when the fan is at near or full speed. Eventually though, as the bearing wear gets worse on the dying fan, you'll begin to hear it on the slower speeds too; which can result in inefficient cooling. The system will try to boost fan speed to compensate when this happens. At some point though, the fan isn't going to be able to continue doing a good job of passing air over the heatsink fins and will need to be replaced. If it's an Intel box, it'll most likely reduce performance to keep from overheating to a point. Worst case scenario, it'll do a hard shutdown. Your OS may/may not like that depending on what you were doing when it happens. If it's an AMD, No guarantee you won't cook the cpu as the cooling systems inability to cool it down gets worse. Either way, the failing fan should be identified and replaced as soon as is realistically possible. It's already working harder than necessary to compensate for the bearing failure in progress, even at the slower speeds. Go to Home Depot or Lowes. Buy one of those big green air filters that's just a plain gauzy pad and comes with a black plastic grille. Get some plastic ties. Cut the pad and grille into pieces to fit the areas of air intake holes. Place each pad piece inside, cover it with a grille, and pull through a few ties to keep the grille in place. It's an easy, cheap way to keep the inside clean. While it's a cheap/easy fix for keeping dust/cat fur, etc, out, it's also reducing airflow coming into the case by a small amount. Which will cause the fan(s) to run a little faster to compensate. No real biggie, it's what they are designed to do. -- To prevent yourself from being a victim of cyber stalking, it's highly recommended you visit he https://tekrider.net/pages/david-brooks-stalker.php ================================================== = Standing on head makes smile of frown, but rest of face also upside down. |

Maybe I should have companded it, and really cranked the level :-) https://instaud.io/1DdB CPU fan speed is register controlled. If a Dell computer crashes, the fan can be heard running like a hoover, because then there is nothing to turn down the fan speed after the power is applied. I've noticed that some Dells specifically will when first powered up will run the CPU fan at or near full speed. Which seems to be the case here. I've got a vostro 410 sitting a couple of desks over that does the same thing. I can't say it's unique to Dell, but, I don't run across many other system builds that fire their fans on full on initial hard start, either. The result is, when machines like a Dell start up, there will be a second or two delay during POST where the CPU fan speed hasn't been set yet. Once the POST gets to that point, the CPU fan can be properly adjusted for the amount of thermal present at that point in time. Aye. My other systems, which are clones, don't crank their fans to full speed on startup, but they will/do adjust speed based on need as the machine heats up. I'm guessing that's a fan noise, but it could just as easily be a disk drive (judging by the "OK" sound it makes nearer the end of the recording). It could be that the fan stops rumbling on its bearings, after the voltage applied via PWM is reduced a bit. Nah, listen closer. That's no HD sound. That's a fan. I know the sound you're thinking of too, and that's not it. While you can peel the label back on some fans, and put oil on the bearing, not all fans actually have an open bearing. A Panaflo for example, you can't oil it because the FDB bearing is sealed. Most likely, this won't be an oil friendly fan. Ball bearing motors get noisy as they get older. In fact, a user is likely to replace the fan due to the noise level, before it ever gets a chance to seize up or something. I have disk drives with ball bearing motors, that I can no longer sit next to, as they're that loud. And the drive still works... Yes, but, would you trust important data on them? I'd be making sure I had backups once a drive gets that loud. You know it's the spindle motor with some age on it, but, as you also most likely know, it doesn't require a total failure to make your ability to access data go bye bye. Replacing the main fan on a Dell can be difficult, due to the five pin interface. Regular PC fans come in two, three, or four pin varieties. But Dell decided five was a nice round number, and the first question I get is "what can I put in here?". Well, there was a supplier of replacement hoovers for Dell, but there's no guarantee they're still in business. It's tach2 depending on the pinout spec you read. They are PWM style fans, vs the older ones that provided tach readout (or none) and let the mainboard alter incoming voltage to the fan to control it's speed. In the case of the two pin fans, obviously the mainboard has no control over the fan and the fan just runs wide open; but you likely won't see those around much anymore. With PWM, it's a pulse instead. If it gets a pulse, the fan gets full power. No pulse, no power. It's a more efficient way to control fan speed, by the pulses per second you send it vs trying to regulate voltage to the fan motor. You just keep 12 volts hot, but, the fan can't use it if the pulse isn't present. And you can control how fast the fan runs by how often you pulse it. You can bypass the fifth pin, since you already have another pin providing tach readout, anyway. What you can't do with those fans is bypass the pwm signal. If you did, the fan wouldn't ever run. http://pinoutguide.com/Motherboard/d...n_pinout.shtml This converts the 5pin to 4pin configuration while keeping fan control in the hands of your Dells mainboard. Dell likes to be non standard in various respects and of course, that includes (depending on Dell model) the pin layout. Or, if you'd prefer to have a 5pin fan because you think your Dell might actually use all five pins and you're losing something if you don't a quick online search will provide them. If it's working now, you have nothing to worry about :-) The above is just a backgrounder for you, for the next time it happens. I disagree... The fan is showing signs of failure at full speed. At lower speeds, you don't hear it, but, that doesn't mean the fan is continuing to operate within spec due to the failing bearing you can clearly hear at full speed. The fan should be replaced. It's not something to just ignore and live with. You preferably don't want to have to replace a fan because it actually went out on you, as by doing so, you've actually ran your cpu hotter over time than it would have otherwise been run. Heat causes premature failures on electronics. You can damage various levels of cache on the cpu by running hot for too long and you may not even notice right away you've harmed the cpu, until you open that one app that taxes it, which used to run just fine, and now bluescreens your machine. AMD socket 7 chips used to be real bad about this. You could toast the l2 cache and not notice you had a problem right away. As the computer would bootup as you'd expect, but, depending on the apps you tried to open, would bluescreen and crash out on you. You actually had a cpu level damaged system which wasn't stable, but, the stability issue wouldn't crop up just by booting windows. -- To prevent yourself from being a victim of cyber stalking, it's highly recommended you visit he https://tekrider.net/pages/david-brooks-stalker.php ================================================== = The length of women's skirts are directly proportional to the current financial climate. |

To me, it sounds for all the world, like something briefly coming alive, then winding down for most of the sound. I think that rules out fan bearings. System boots and works fine, and it doesn't sound like a HD, so rule that out. You most likely have a failing CPU fan. You should replace it as soon as possible. The reason you think it's okay because you aren't hearing that noise all the time is because you're only hearing it when the fan is running at or near full speed. It *does* have a bad bearing. Also, the sound now comes every time after an over night, but I used to hear it once in awhile very infrequently, since new. Thats a quality Dell for you. ROFL. No, but, seriously, your fan is dying, replace it. I think it might be some sort of maintenance function. Could be coming from the speaker (?); difficult to tell on a fly. Nope. It's the fan. I've heard that noise so many times doing techie work I'd be willing to bet money on it. -- To prevent yourself from being a victim of cyber stalking, it's highly recommended you visit he https://tekrider.net/pages/david-brooks-stalker.php ================================================== = Real women don't deflate when you bite them. |

Thanks Ron C .
It definitely seems to be the CD drive spinning up then down. It didn't have any boot priority set, so I set it at 2nd after the HD set at 1st. Hope this eliminates the sound; we'll see; let you know. Thanks also to all responders ... |

Hope this eliminates the sound; we'll see; let you know. Thanks also to all responders ... If that's a CD drive making that sound, there has to be a disc in the tray. Is this a dual optical drive machine ? Have you checked both trays ? Optical drives don't even crank the spindle to a speed like that, unless there is a sustained read occurring. They start reading at 1X for "casual" reads. At startup, the BIOS won't be reading at 5-6MB/sec and will only be "poking" the drive. Only the actual boot sequence would read at 5-6MB/sec (such as when a WinPE boot image loads sequentially). And your drive isn't "insane", because the speed does eventually come down. That doesn't strike me as optical, *unless* you're leaving a disc in the tray *and* the optical drive is defective somehow. Â*Â* Paul I've had a similar sound once a long time ago when I had a very out of balance or off center disc in the drive. But it only took a couple seconds to figure it out. Rene |

Interestingly, someone mentioned, that this might be related to
temperature. Computer room is essentially unheated over night. We're having a relative heat wave, upper 50sF, so startup temperature was at least 15F warmer. Guess what ? No sound today ! |
