Hi just bought a GuruPlug Server - PLUS.
After 2 months waiting for that plug computer to arrive, I finally start playing with it.
First disappointment came after about 2sec. That plug  computer have a fan and it makes more noise than any computer I have ever owned !
It's annoying to the point where I'm not 100% sure it's normal. Does anyone have a GuruPlug server plus and can confirm that it's unusable because of the noise ?

Yeah myself and 2 mates received ours a couple of days ago. They are ridiculously noisy, similar to a high powered vacuum cleaner!

Agreed. I now have a jet engine in my house. Anyone thought about opening it up to change the fan?

Same problem here.  It sounds like a small hair dryer.  I'll take some pictures and post.

Here's some pictures of the inside.  The fan is behind the USB/eSATA ports.  it appears to blow air into the power supply.

Looks very basic - surely that could be replaced with something quieter?

gsk99, thanks for uploading those images.
I'd like to know details about the fan.
electric power socket, diameters, and so on.
thanks in advance.

The fan is a Sunon Maglev KD0520PEB2-8.  The tech specs are at http://www.sunon.com.tw/products/pdf/maglev.pdf.  If you decode the model number using that document it's 5V, 20mmx20mmx6mm, ball-bearing, mid-speed, 2 wire.  I've seen 20mm fans in the 21-23dba sound range in a quick search online.  I  don't know how much this one is but it seems a lot higher than that.

Thank you for the photos and for the comprehensive information. Am I right that there is no heat sink / heat spreader anymore? I don't want to imagine what will happen if the fan fails  Undecided

Slightly off-topic:
I can see that the second (internal) SD-card slot is installed. Did the Plug come like that or did you solder it yourself?

Is this the "Professional Upgrade Kit"? Or just the Basic version?
I was hoping for a new part-case with a temperature-controlled fan
and a better heat-sink.

The second SD card slot was installed when I got it.  What you see above is the latest version of the GuruPlug Server Plus completely unmodified.

I would have hoped to see the fan at least be temperature controlled but that doesn't appear to be the case.  It runs full speed all the time.  I think they would have been much better off with a redesigned case - even a bit bigger if they needed it - to get a better fan in there with the right heatsink and venting.  I don't care about the size.  What I care about is all the features and low power consumption.  The automatic booting on power-up is a great option too that makes this a great device for a remote situation when there's a power outage.  Ultimately I could see myself just abandoning this case altogether.

On the plus side it worked perfect out of the box.  Fired it up and it came up as a Wifi AP right away.  Connected my laptop wirelessly, logged in, plugged in an eSATA drive, and away I went.  Nice little unit if this heat issue gets properly straightened out some day.  I'd like to see them touting this at CES or something with that fan running.  It won't be received very well.

I'll play around with some other features like the SD slots, etc tonight and see how that works.

Thanks gsk99 for further info in details.
I'll try to find similar spec of fan from our local market.

The fan is a Sunon Maglev KD0520PEB2-8.  The tech specs are at http://www.sunon.com.tw/products/pdf/maglev.pdf.  If you decode the model number using that document it's 5V, 20mmx20mmx6mm, ball-bearing, mid-speed, 2 wire.  I've seen 20mm fans in the 21-23dba sound range in a quick search online.  I  don't know how much this one is but it seems a lot higher than that.

Thank you, danke, merici, grazie and whatever.

It seems to me that the biggest issue is the case... I don't think such a small fan can make that much noise just by itself. I'm wondering if when it's opened, you get that much noise

It probably has something the do with the way the air flows around the ethernet port and the distance of the fan to it. They shipped mine but it hasn't arrived yet so I've been unable to test the fan.
