Is there any way to control the fan speed of a LH6000r

Is there any way to control the fan speed of a LH6000r?

The Thing is just soooo annoyingly loud... and due to active fan speed control it doesn't change a thing even to remove all but 1 fan ... which must be running at 100 000 rpm then :-)

In my LH3, for the same reason, I replaced all the fans with top quality 3-wire (speed sensor) models and now the machine is pleasantly quiet in operation. A huge improvement. No problem in nearly two years. Inexpensive fans, easy job to do.

Thanks for your reply.

I'll try to change the speed of the fans by soldering a regulator to the fans,
if that doesn't help I'll by new fans.

Where did you find top quality 3-wire (speed sensor) fans?
My LT6000r has 6 fans (3 sets of 2) that are 120mm x 38mm.
The 120mm thermostatically controlled fans that I have found are near $20 each.
$20 x 6 = $120
Is that what you paid for yours?
Were you able to install one fan instead of the gang of two roaring fans in each location?
Thank You

Hi Bryan Smith,

I just bought no-particular-brand (maybe Arctic Cooling) fans just watching for the best cfm/price ratio.
I think I paid about 50$ total without reducing the total number of fans.

If I were you I wouldn't mind spending a few bucks on fans, keeping in mind what that thing costs you only considering electricity bills.

Hey Bryan,

You can get a 5-pack of 120mm fans from Tiger direct for $20. Here's a link:
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1456373&CatId=802

They claim to be 80% quieter than standard fans. If you try it and it works, write back and let us know.

Good Luck,

Okay..they were cheap enough, so I bought a pack of 5 fans from TigerDirect.
I discovered that they are 2 wire fans and not 3 wire fans.
Could I make these fans work?
Maybe...but I do not think it is worth the risk to my server.
Now, I am stuck with these 120mm case fans.
I am now fighting with TigerDirect for a RMA on an opened box item. But that is not reason for this posting.

Observations I wish to share:
1. Live with the noise.
2. Move the server to a location where you can not hear the noise (IE: Computer Room)
3. Make double sure the 120mm fans are three wire units. The third wire is a sensor wire, used for many things. On Desktops, this is used to display the fan speed in the BIOS and other utilities.
HP Netservers use this to indicate if the fan is operating or if it has failed.
4. In order to get a high quality fan that has the 3 wires, a owner/operator will need to spend some $$$.
5. Aftermarket fans will be narrower than the stock OE fans, but is not an issue.
They will just snap in place of the old ones.
Also, some soldering will need to be completed as you will splice the new fan wires into the existing fan wiring harness.

Sadly, my LT6000r is in my basement computer room/lab/workshop.
Noise is a problem for me.
So, I play with it (wicked fast for an 8 user network!) as I practice for my advanced Win2003 certs and then I turn it off.
