Help! Dell 4300 rear fan quit. Looking at the fan and power assembly, I see a white substance that looks like?

Dell's customer support have always been great for me - they will be happy to give you the right spec for the fan.\n\nAny of the major electronic component shops (like Maplin Electronics etc) will be able to supply the fight stuff.  You should be able to take out the fan you have and (with the correct voltage applied) test it - it is entirely possible that the electrical connection has simply come off.\n\nThe white stuff is likely to be either heat transfer compound or some sort of adhesive used to stop components shaking loose.\n\nHave fun :-)

yea this has happened to me before i think it has to do with your power supply, is this an older PC?  Pretty sure its the power supply shorting out a Lil and making it think its restarting

It's probably either the case fan or the power supply fan. I have hit the case a few times and it will stop. Dont beat on your case though ha ha. Open up the case, and see if you can track it down.

Just check the cables of the floppy disc that is in motherboard side. I think you just missed that side.\nThank you.

You are going to need a new case (commenly refered to as a shell) for that machine... repairing the power socket is tricky. its best to swap out the parts into a new shell. sniff around on e-bay or if the machine is under warrenty contact dell and have them send you a new shell and put the HD memory and drive in yourself...

If the computer is under warranty,I would contact the company that made it.If warranty is out and this is a problem that has just recently occured then I would either take it to a computer technician or If you know anything about going inside one,I would say your power supply is on the blink and needs to be replace.If the heat is coming from the general area of the power supply,I would most deffinatly say this is the problem.\n\nGood luck with that computer

it is most likely overheating. Try a monitoring program like sisoftware's SiSandra light.  Its free, and the environment monitoring tool will tell you the temperature of your Processor.\nhttp://www.sisoftware.co.uk\n\nIn the meantime, check that all the fans are running and free from fluff etc.\n\nIf you have replaced the heatsink on your processor, make sure you have used a thermal paste between the heatsink and the processor.\n\nGood luck

It would make noise when the processor gets hot and the fan kicks in. Sounds like a cooling issue. Have it checked and it probably needs the vents cleared or it is being blocked. Since it's new it should still be under warranty. So don't wait before it expires before you bring it in for service.

Maybe your power supply just failed or something isnt snuggly plugged in. It could be that something got caught in the fan and it shut down from over heat automatically

It can be a couple of things.\n\nLikely culprits?:\n1. the cooling fan.  Check for buildup on the rear fan, use canned air to clean.\n\n2. The Processor fan. Look on the motherboard and watch the little cooling fan. Clean with canned air or replace.\n\n3. A warped CD in the cdrom drive. When PCs start they spin the drive. make sure it's empty.\n\n4. A heavily fragmented hard drive. If the drive is fairly full the drive has to look all over the place for your files. Delete all uneeded files and defrag the drive 2-3 times.\n\nif your PC is losing the time, that is due to a bad motherboard battery. If it's under a year old, it should be under warranty.

Its not the fan on your hard drive (it doesnt actually have one!).  It is possibly a dirty fan, and you may want to open the case up and clean the fans.  Just use a paintbrush (the big house painting kind) and you can easily wipe of all o the dust on the fans and heatsinks in the computer.  If it sounds like a loud BUZZing noise, then it is likely the bearings on the fan went out and it will need to be replaced.  If it has always been this loud, consider buying a more expensive "quiet" fan to replace it.

well my first thought is....it over-heated and died.\n\nHD's produce heat, quite a bit of it actually, so it being in an external HD case, when it's meant to NOT be covered, probably caused the temp to rise and your HD to burn out, or it could just be normal  mal-function, and the drive could just be done.\n\nalso sometimes it's connectors etc....there are many things to troubleshoot when it comes to a HD not functioning properly

Be careful.  Get fans around it.  Your going to need a new fan, it could be tomorrow or in a couple of months, but it is about to quit.  Until you can get a new fan, get a portable fan down there to cool your system down or you could end up with "melt down".  Good luck.

It is cheap LED, if it is giving no problem, ignore it. Else give it to HP support centre for correction if it is in warranty period.

if its making a loud whurrrrring sound, like a hum in way that means your air input fans and/or power unit fan are clogged with dirt and the fan is straining, causing the noise.\n\nif you have a fan on your processor as well, check it.

You need to get it checked out ASAP.  If you have multiple fans, do they all seem to work ok ?  Is the power supply fans working ?  I have seen/smelled computers in the past where you can smell burning plaster/rubber smell if the power supply is not getting enough ventilation from the fan.... usually this is caused by a bad fan or fan that just doesn't work anymore.  But that smell is a pretty good indicator that (usually) something is overheating.\n\nYou should at least check for hotspots in your case, and verify that airflow is adequate for all areas within your case (i.e. fans still blowing air). Any electronic components that are exposed to overheating for any length of time will likely fail.\n\nAnd yes, it could be potentially dangerous for your PC components to keep your computer running with that smell permeating.

It proably is the cooling fan, or related to it. First try getting something like compressed air, sorry ask someone who knows better for the best answer, and get the vents cleaned out and the dust off the inside. If it still doesn't work depends on how well you know what you are doing. Either take out the fan and replace it, or take it somewhere that does computer repairs and have them replace it.
