New 8300 and fan replacement

Just got my new Dell Dimension 8300 2 days ago and the while in general I am very pleased with the performance the fan noise is making us crazy-it starts out quiet enough, but just play Warcraft for a while and you can't hear yourself think! I know that I can contact Dell and ask for a replacement, but after spending some time searching these boards, this appears to be a common problem and I will simply get the same fan if I ask for a replacement. I have replaced every part on a computer except a fan and I am not electrically inclined. However, I am willing to spend the money and time to replace the fan if there is one that can easily be swapped without cutting, soldering, crimping,etc. My question is has someone found a 3rd party fan that has the same type of connectors, appropriate size and cooling specs that I can buy?  Are there any good step by step instructions to do this?

Thanks in advance,

Laurie

Re: New 8300 and fan replacement

OMG, I was just going to start a new thread on this when I came across this one. I've had my 8300 since christmas now, but although I have noticed this since then, lately the fan is driving me CRAZY!! After 10-15 minutes you cannot here yourself thing and I have to shut it down... I cannot play games i.e Flight Simulator or anything else for that matter because it gets so loud ! Also if you run programs like virus scans it just goes crazy. Sometimes when I switch on the computer after turning it off after the noise gets too bad, it goes so loud for the first few seconds I really do thing that's its going to blow up!!

I thought it was because I had a Radeon Pro graphicd card??

 

Anyway, can this be changed like Laurie asked?

Re: New 8300 and fan replacement

the funny thing is the power supply fan is totally silent. You don't even know it's running.

How hot really does a cpu get  that the fan has too run so fast???? If you want a good laugh, install chessmater 9000 and play some games.

Jet engine time.

Re: New 8300 and fan replacement

Yes, Mary G, I do understand that I can contact Dell but I also understand that they won't provide me with the information I am looking for, namely a third party fan that will do the job but do so quietly. I got a great price for a good performance machine and while I am somewhat disappointed that Dell has not changed their design given pretty significant feedback that this fan is not acceptable, I also understand the probable whys and wherefores behind this. I was just hoping that some other user who already dealt with this could give me some specifics.

Thanks,

Laurie

Re: New 8300 and fan replacement

They use an odd fan size. I was never able to find any online. I think the manuf..... custom build it for Dell  all the fans.

Im afraid to ever buy that XP they have. The top of the line DellIt has like 2 cpu fans I think! What is the noise rating on it?????????

I bought my 4300 after reading a review online. They guy doing the review said it's dead silent! Maybe he was deaf. How can you not hear it????

Please someone write Dell, and tell them we want quieter fans in the future.

Re: New 8300 and fan replacement

The Dimension 8300 fan is loud because the power supply wire is hitting the fan when its spinning. In order to make the fan to go to normal speed. Open the case and check the fan and move away the power supply wire. That should fix the Extreme noise coming from the fan.  Also its normal for a fan to make little noise. It just tells that the fan is working. If it was so silent. Then we would not know whether the fan is working or not. Also its normal that the fan goes little bit more louder. Because if the pc is tasked heavily. Then the fan have to do hard work. That can make the noise louder. Once the pc is not doing anything again. Then the fan goes down to its normal speed.

Punjabimunda - although that may have been your particular problem, it is not what most of us have experienced.  The problem is the use of a thermoregulated fan that triggers too early and sounds like a turbo jet.

Original Poster - search the forum, there have been quite a number of posts from various folks that describe methods of swapping out the fan.  The size is a standard 92mm fan, 3 pin.

Good luck.

Re: New 8300 and fan replacement

First, english isnt my native language, so forgive me any mistakes plz Smiley Wink

I have that Dimension 8300 too (and that noise problem) and i modificated it as follows:

1. i replaced the big loud fan under the green plastic device with a Papst Fan 3412/NGL 92x92x25 mm, connected that new fan to a molex connector (4 pins)

2. i replaced the cpu cooling device with a Zalman CNPS 7000A-AlCu, i put it on the motherboard connector (i replaced the old dell retention module (dell oem) as well with a new standard one and modified it a little bit so it fits to the board)

you must do both steps, because the papst isnt powerful enough to cool that hot prescott and the zalman alone cannot put the hot air out of the case, but both modifications together are very nice (and silent) Smiley Wink

in the future i will mod the power supply a bit with another more silent fan (papst)

btw: there are 2 grills in front of the power supply fan, you can cut out the (not necessary) grill from the computer case to make the dimension even more silent
