How To Control Fan Speed on Older Compaq Proliant ML350

[gc]

Hello.

I have an older Compaq Proliant ML350 (Dual Intel Pentium® III 1.0 GHz 
Model) running Debian Wheezy that I have been using for many MANY MEEE 
NEEEE years as a web server. It works great, everything is fine, I will 
continue to run it until the end of time. lol

That said, I have tried off and on thru the years to control the fan 
speed. It runs constantly at full speed. It's very loud. I have tried 
using fancontrol and could never figure out how to get it to work on 
this system; and while on other systems fancontrol works perfectly fine.

What's interesting is that the fan is 100% controlled in a Microsoft 
Windows environment. I don't like Windows and I would rather go deaf 
listening to the fan running on Debian than to use the machine with 
Windows installed.

But, if anyone can help me it sure would be nice to get a muffler 
installed on this server. If anyone has advice on how to gain control of 
the fan I'll be forever appreciative.

Here's the link to the specs-sheet on the system I have. It's completely 
stock with no modifications:
