loud Drobo - disconnect fan?

Don't disconnect the fan.

 

How long have you had your Drobo? I have had two for about half a year or so and both are extremely quiet. I never hear the fan at all. Maybe something is wrong with the fan on yours. Try emailing Data Robotics.

 

Whatever you do, do not disconnect the fan. The heat from the from the drives could cause failure. Email Drobo and see if there is a solution. Good luck!

 

Are you running the latest firmware? May be there is a firmware update that addresses the fan problem. Could be the drives are getting to hot hence why the fan is going into over drive.

 

A couple of things-

-I have never heard my fan run on high-speed. Even when it first powers up and runs the fan for 5-10 seconds, I don't believe that is it's full speed.

-I also have a Drobo V2 that is nearly silent. Whenever it kicks on, I'm not sure whether it is my mac running its fan slightly, or the Drobo.

-One thing you can do is open up the Drobo and make a note of the fan size (i think it is 92mm, but best to be sure. Then, go to egghead and purchase a high-quality, low noise fan and replace the stock unit. I've seen people do this before when their fan either stops working or they too are seeking a quieter option. One word of caution-the Drobo uses a standard cooling fan that is also found in a PC. But from what I have read, some soldering is required as the Drobo ices a custom plug to attach the fan to the motherboard, and you will need to modify the harness that comes with the fan to work with the Drobo.

Good luck, and if you do go this route, post some pictures and advice you gathered along the way.

Oh, and in response to your original question, do not unplug the fan.

 

I just replaced the fan in my unit for a quieter one. The old fan was very loud and driving me crazy. The new fan is completly silent and is about 14db. I should have done this a long time ago.

 

Awesome. How difficult was it to change the fan and did you need to resort to soldering? Also, what fan did you end up using? Thanks!

 

I would also like to know this.
I've had the drobo for a week and it makes a lot of noise.. fan is on most of the time, even if the disk is not being accessed at all.

Even when the fan revs down to almost silent, it will only last for a minute or so, then goes up again.

I'd understand if I was doing heavy data transfers, but this is not the case.
Also when I get home from work, the fan is always on at full speed and the computer has been idle for hours.

 

Damn. Was hoping to see a reply in here about replacing the fan and the process.

My drobo has just recently started having fan issues.

It's very loud to the point that if my apartment is quiet I can hear it from my bedroom in the living room.

It almost sounds like white noise or water running through pipes in the wall.

I've contacted drobo/data robotics and I'm told I'm out of warranty and can't RMA my unit unless the fan is making squealing noises. I'd have to purchase drobocare and pay like $160.

Not going to happen. I'm hardware savvy. I can replace a fan. but have never been inside a drobo and heard that there's SOLDERING involved?! (W..T...F..)

Anyways. If anyone has done this can you please give some insight? Thx.

Found this link with instructions on opening the drobo for fan replacement.

 

I have a dock that has 2 very loud fans in it, but the speed is variable. If I'm caning the four drives in it (Which is rare) I leave the fans ramped up, but if they are idling i turn them down. I have become accustomed to the noise and don't notice it as much now.

In a full enclosure though, you need the cooling, so don't turn them off.

 

I've uploaded the instructions to Scribd in case they ever vanish. Link.

 

Just an update. Just did this procedure using the same fan recommended in the tutorial I linked to. Took me about an hour. Disassembly was tricky with the clips. (One has NO flex due to length) and splicing the wires for the fan took a bit.

No soldering needed but the old fan's connecter had to be severed and attached to the new fan.

My drobo is completely silent now!! My ear right next to it can barely hear it!
(Pushing almost the exact same amount of air too.)

 

Hi, I have another loudness problem with my just installed Drobo. Two drives (WD black caviar 1,5 TB) inside are very loud when writing/reading. And they doing that almost all the time, even when there is no reason for that...I'm mad of that clanking.

 

Replacing the Drobo Fan

My four-bay Drobo Gen 2's fan sounds like it's dying and I called Drobo and since it's out of warranty, they will "consider" replacing it for me. I'll update if that happens.

Meanwhile, I'm going to order a couple of fans. Here's another site about how to replace the fan on a Drobo FS

Ive tried a couple of drobo drives over the last few years, but hey unfortunately all had big issues with the soundlevel. The fans where even on when there where no drives inserted. Since the drobo was in my livingroom I decided to send it back within a few days.

Its not only the sound, but drobos are also really power inefficient. Really annoying because they look so awesome
