Now the new hard disk has been working fine for several day~~~::)) Thanks so much for your help!
Since I have replaced the hard disk, I am thinking I may replace the fan. it's really too nosiy...

I check the Wiki I decide to buy this model:

Before I order this, they asked me if I need a 3-pin or 2-pin port for this? I remember it should be 3-pin but is there anyone know about this? And is this fan all right?

three pins/wires are needed, 2 for current, one for sensing/control...

but, before you replace it, consider just silencing the one that is in it now...

I did that by
- disassemble & remove fan
- carefully lift/peel/remove the small green sticker/seal on the one side of the center of the fan
- lubricate it with a bit of light-duty grease - not too much ... don't use teflon lubricant or WD-40
- test if it is quieter (without reassembling)
- if good, wipe excess off the area where the green sticker goes back on, & replace the sticker
- put back together & enjoy silence...

I did this with two of my older boxes, and it worked great. In fact, they are quieter than my other box that has a supposedly better Silenx replacement in it.

ymmv ... good luck

also, see

LS1 (foonas, nfs, Tranmission & p910nd print server, Firefly for my Roku)
LS-HG500 (Lenny)
Various LS-Pros v1,v2 (unbricked w/ serial & jtag)

Hi Davy_gravy,

Thanks for your reply.. it's so nice~~~
Buti I have a little different idea with silencing current fan. I used to fix my laptop's fan with some lubricant. But for this fan, I chceked it's document, it should be AD0412LX-G76-LF :?: , it's using ADDAŹ¼s patented hypro bearing (hyp) technic which had very little oil inside the fan. it means even I add some lubricant it won't have a good condition. The best method is to replace a new one with the samiliar model. Of course it's all based on my guess. I never handle it before.....

I have just ordered two fans with several different kinds of lubricant, I am going to try your method first...

Thanks for your hints again!

Today when I come back from outside, I found the LS2 is really silence there. The fan stopped working...... :shock:
It seems I really need to replace it.

I remember last time I received some error from avt_xxx :?: it said system detected fan fault...

I bought a 3-pin fan from Newegg. Only problem was that the wire color coding is different but it wasn't too difficult to figure out.
