Hi,
Can anyone suggest a quiet hard drive for the kuro.
I just got my kuro yesterday and salvaged an old 20GB samsung drive from a very old PC. Everything is working but the drive is very loud.

Thanks,
Derek

Just wondering if anyone tried running a 2.5inch drive in a kuro?
I found an adaptor...

May be quieter and use less power. Small bit slower though........

I have a Seagate Barracuda 200GB in mine and it's quiet. The Kuro's fan is more noisier.

The Kuro's fan is very noisy, even on low-speed rotation... so I just disconnected mine altogether. With the latest avr_evtd you dont have to worry about the machine shutting down if there is no fan.

jkk - YOU SIMPLY DISCONNECTED IT ?????

WOW

can you pleae tell me :

what's the temperature on the fan (or at least - put your hand on it, tell me how it feels)

what is the rotation for the hard disk you are using (5500 rpm ? 7400 rpm ? )

for how long has your kbox been on ? (just type in $ uptime)

what's the temperature of the hard disk ? (just type in sudo /usr/sbin/hddtemp -nq /dev/sda ) Please, install hddtemp in case you don't have it.

I wanted to remove mine, but they said my kurobox could blow up on fire...

I got a quiet drive now in my one but the fan is noisy.

My girlfriend wants me to switch it off as its in the living room and she cant understand why I need it on 24/7........ She dosent seem to understand how amazing the kurobox is :roll:

I disconnected the cables connecting the fan to the plug on the board, and also removed it from the case so now there is less blocking the fan holes in the back. It's just slightly warm to the touch, not very hot at all. My wireless router (DD-WRT) gets a lot hotter, and runs without a heatsink. Maybe one day I should stick heatsinks on my kurobox chips & router chips!

My uptime is less than 2 days, since I just recently stabilized my setup.

Rotational speed is 3600rpm
# hdparm -H /dev/hda

/dev/hda:
drive temperature (celsius) is: 42
drive temperature in range: yes

The trick is that I'm using a microdrive, not a 2.5" or 3.5" hard drive. I don't know if I'd recommend it yet, though.

jkk,

Ahn, explained ... low rotation, small drive :)

I have a big 250GB 7200 rpm drive, I think It can't go without cooling inside the kbox...

I'm experimenting it with a resistor in series to the fan, the fan gets a little bit quieter, let's see if it's going to work ....

Maybe you can use a potentiometer to have a variable speed, coupled with the 2 possible voltage settings from the Kuro's AVR.

that would be a nice idea to try and find a "ideal spot", where the noise is minimum and the HD is still on it's operable temperature...

This is what I have done so far:

I think I'm happy with my kuro now. But will try this idea in case the noise bothers me again.

My stock Kuro fan became noisy after about a year of use. Tried the oil trick, worked for a while and then the fan failed completely. So I looked around for a replacement.

It seems quiet fans with the third control wire are a bit hard to find? So I went with a Zalman fan mate for my voltage drop and a Scythe Mini-Kaze for the replacement fan.

http://pccasegear.com/prod5057.htm

The mini kaze id pretty loud (despite claims) without the fan mate, but with a bit of fan mate adjustment it’s near inaudible.
You can mount the fan mate inside with a bit of double sided tape like so:

I have a 320 barracuda in my Kuro, it’s pretty quiet, no crunching. And they are tough as nails. However I can tell you that the new Samsung spin points are the quietest, I put two in my home server the other week. I can hardly hear them. Have a read on http://www.silentpcreview.com/

BTW as per the wiki if your running he stock fan try slowing it down with:

Code:
  /bin/echo -n '\\\\' > /dev/ttyS1

Put it in a startup script, and have it slow on boot.

Hope this helps.

That is nice; maybe mount it so that the knob sticks out of the rear, so you can turn it without dismantling your box.

I agree, a drill hole plus a small grove cut in the top of the adjustment knob for a screw driver would do nicely.

But for me I’m happy with the lowest setting. I’m not worried about overheating, I think it’s a non issue, IMO.
