PowerEdge 2650 - Fans are REALLY loud

We just recieve a few PowerEdge 2650 systems.

Upon powering them up we immediately noticed that the fans are extremely loud and we immediately thought there was something wrong, so we powered down the system.

After inspecting the system to make sure we hadn't forgotten to remove something that would cause the fans to run this loudly, we powered the system back up.

Is this level of noise to be expected?

I can hear these fans over the noise of our A/C unit, and all the other servers, in another room down the hall from our server room (about 20 feet away).

Any info would be appreciated

Hi,

The PowerEdge 2650 fans are loud, very loud.

Engineering is aware of the issue. On other systems such as the PowerEdge 500, there has been an upgrade to the System BIOS to allow the temperature sensors to control the speed of the fans. I expect there may be a similar upgrade on the PowerEdge 2650.

Mark,

Is there any possibility of the same thing becoming available for the PowerEdge 1400's? I have two PE1400's SVCTAG's CXZY701 and G9BB901 that always sound like min jet engines. Running different tests I discovered it's the fan in the front of the units, that cools the PCI slots that makes the majority of the noise. I always figured it just came with the territory so to speak, running servers versus standard PC's. However, this past Friday I received two PE1400SC's SVCTAG's 7LP1G11 and 8LP1G11 to setup for a friend. These systems are significantly quieter. That made me wonder if they were using a different fan and if I could upgrade/replace mine with these.

Thanks!

Hi Bill,

These are the parts required to lower the noise level on a PowerEdge 1400:

Note: In order to make the fan more quiet it was necessary make it slower. Since the processor fan is now operating at a slower RPM, it was necessary to re-design the processor heatsink and heatsink clip to provide for greater heat dissipation.
In case of dual processor systems, replace the heatsink and heatsink clip for both processors.

· Rear Chassis Processor Fan P/N: 7C219 (This fan mounts to the read of the chassis and has finger guards)
· Front Chassis Fan P/N: 8C152 (This fan mounts to the front of the chassis in a fan housing and has no finger guards)
· Processor Heatsink P/N: 2C970
· Heatsink Clip P/N: 4C788

Good morning Mark! Thanks for the information on the parts. This is GREAT news. I'll get to work on pricing and make plans to order the replacements. Gee, I wonder what life will be like not having to wear earplugs in my study :-)

We just received 3 new 2650s, and had a chance to power one of them up yesterday. When I first powered up the 2650, I actually flinched because of the loud fan noise. I have been working with Dell servers for over 6 years now, and have never heard any others that were so loud. When we had all 3 powered up in our server room yesterday, we couldn't use the phone due to all of the noise. We have 12 other servers in that room, and their combined noise doesn't even add up to the noise produces by one of the 2650s.

Needless to say, I am rather dissappointed. I hope that engineering comes up with a fix VERY soon, or I might go deaf!

Well..I apologize for this comment but..

They are servers. Dell does a great job on their servers.

As you can see here:



There is a lot of horsepower in a relatively small space. 5 10,000 or 15,000 rpm drives which in themselves are very loud. Plus the tight spacing of the drives causes a lot of heat. That requires a lot of air to keep it cool.
Plus the tight packing of the system does not do much to keep noise down. There simply isn't enough room to dampen the sound.

I myself have a PowerEdge 6100 in my bedroom with 6 9 gig baracuda drives in it. Loud doesn't even come close to explaining it.

I agree that they do a great job with their servers. I wouldn't buy any other brand. I also realize that servers are just plain loud.

However, the new 2650 screams when it is on. I have 12 other Dell servers in the same double rack enclosure as the 2650. I am not exaggurating when I tell you that powering on one of the 2650s is louder than all 12 of those other servers running. It sounds like the cooling fans are running at 50k rpm or something.

Before I had the 2650s, I could use the phone in the server without a problem. Now, I have to yell for someone to hear me, which is useless, because I can't hear them.

I hate to complain about Dell products, but the new 2650 is too loud. Don't worry Dell, I still love your products, and will continue to buy them, but PLEASE make the 2650 quieter!!

Hi,

This is hard to believe if you have not heard a PowerEdge 2650, but it is at as loud as a PowerEdge 6100, probably louder.

I know our engineers are "hearing" your complaints, and I hope they will find a way to lower the noise level.

Thanks for your help on the forums, it is greatly appreciated!!
