Dell will replace the fan under warranty and you do not have to return the system.  Phone Dell Technical Support @ 800.624.9896 and request to have the fan replaced,   Have your system's Service tag number and Express Service Code handy.

Thanks for the quick responses.  I did contact Dell and they will replace the fans for me.  They believe it may be the heatsink but are replacing the fans too.  Tier two tech support was extremely helpful.  Tier one was definitely less knowledgeable but she did try.  I will check out the other forum doing the "8250 fan noise" search and see what I learn.

Thanks again!

Playing games with heavy graphics will cause both the fan on the vc and the case fan (which cools the cpu) to spin at a higher rpm to cool things down as these components heat up. The higher the rpm the more noise. Is the noise changing as you're playing? Try cleaning off the fan blades. Also, with the case fan, remove it and peel back the sticker thats in the center and put a drop of 3 in 1 oil in the center.

This system is less than 2 months old.  The fans and the system inside are immaculate.  There are no obstructions or reasons why this system should make noise.  I've upgraded the graphics card, sound card, and hard drive and the system still makes this loud obnoxious up and down whiiring noise.  It is obviously the fans or the cpu fan to be specific.  But, after reading the boards, this appears to be a common problem in many 8250's with this daetech (sp?) fans. 

I have already contacted Dell about this and plan on calling them back today to see if they will replace this fan with a NMB fan instead of this loud datech fan that is currently in my system.  If the customer service wasn't so good (aside from the original long hold time on the phone), I can honestly say that I would be alot more agitated about this than I am.  Dell seems to be stepping up and taking care of this problem, it'll defintely be interesting to see if they follow through completely.  I'll post and let everyone know.

Hi Rosanne4, I've also read several complaints about the daetech fans. If you need any help in customer care, contact "Dell-Cathy". She's very good in assisting getting matters resolved.

A few more comments

1) As you probable read, I have two 8250s - originally, one had a Datech fan and the other an NMB.  The one with the Datech was not only louder, but it seemed to be very sensative to changes in available power. When the video card was in heavy use or the hard drive spun up, the fan would whir up and down - fluctuating. The NMB runs steady at all times - no straining/whiring up and down.

2) Both the NMB and the Datech fans speed up when the system is under heavy use - they both have a thermal regulator that increases the fan speed if the case temperature rises.

3) The NMB fan is MUCH quieter at high speeds than the Datech (I could hear the Datech fan roaring in the next room) but is still louder than when the system is idle - it's not unbearable/distracting though and certainly can;t be heard from the next room over.

4) Dell sent me a replacement fan when I originally called to complain - it was ANOTHER Datech.  I tried it out and it was just as bad.  I called them again, and this time they sent out a tech rep to install a new fan - the tech rep brought an NMB brand fan and mentioned that it's the only fan he uses when called about noisy fans (which he said occurs often).

Hi,

  I'm having the same problem here, have the 8250 the Datech's fan sound like a jet taking off.  I have had 4 fans and eah one was a Datech.  I called 2 days ago and asked for a NMB they told me they couldn't do that it's not the one that came with the system.  Would you be able to tell me if the 4300 Pentium 4 NMB fan model # 3612-KL-04W-B66 is the same as the one you have in the 8250?  Or if possible can you try and get me your model number on your NMB fan?  Any help would be appreciated.

                             Thank you,

Thank God this is starting to show up more frequently as i can still remember how much i had my regrets after getting this computer and just when im so excited about going back to Dell and getting a powerfull pc with all the goodies required for my gaming, i began to notice that dam Humming Jet sound constantly everytime i play my games or my 3d-srceensaver pops up and man did i freak out!  Been calling Tech support and they say their is no NMB fan as there is only a Daetech fan for replacement and im not going there.

If anyone has been able to resolve this problem, owning a Dimension 8250 please let us know. I "apreciate" it ....

After going over the boards and listening to all the complaints on these fans, I'm still having a hard time believing that Dell is still shipping these systems with that fan.  What is up with that?  Do hundreds of complaints not warrant a change in hardware or what?  Aside from being a major inconvenience to the people buying the computers, it has to be quite an expense to keep sending subscontractors out to replace the fans over and over.  Where is the logic here?

Anyways...

I'm still waiting for the place to come out and reinstall my fans and heatsink.  I asked tech support for an NMB fan yesterday, but they just issue the order and don't know what fan will be sent out.  This should be interesting because if it is a datech, I'll send the guy right back.  What I am wondering is this:

Has anyone replaced this fan with any other fan (that they bought themselves) that is very quiet?  I'm seriously considering just buying my own fan that is "low noise" and better than both the NMB and Datech.  Although I have no idea what I need to look for to actually do this. 

Any suggestions?
