They are, for their size, the fan-noisiest of the boxes.
The trick with those is to buy zx6000s - they have a quiet fan mod in them which makes them much quieter. I think the zx6000 has a side vent in it that the rx2600 lacks too maybe? It's in the lid behind the CPUs. The only problem is they are also designed to run stood vertically in pedestal config, not laid down in rack-ount mode. Mine is a zx6000 with no skin. I bought (from HP!) a metal pedestal stand but don't have any other casings for it at all (including a front panel).
To be fair, it's not surprising the rx2600 is loud when you look at what it's cooling. Have you stood behind one when it's running? It's like sticking your head in a toaster oven!!
Also, for what it's worth, I used to have 24GB of RAM and a (useless for VMS) FireGL AGP card in my zx6000 and it used about and extra 150W. the RAM seems to suck up a LOT of power. I knocked back to 8GB which is about what most consider minimum for a dual Itanium. Notably I removed a CPU from it and that only scrubbed about 40W off the power at idle, but I guess it uses a LOT more at full usage.
FWIW, it was incredibly quiet and COLD in my basement for about 10 days
late Oct. and early Nov. post Sandy without all of the space heaters.
I have just the opposite issue. Small room with a LOT of gear in that I also have to sleep in comfortably. On COLD days it's not an issue. I just rely on my Mac Pro (2x dual-core Xeons and 6GB FB-DIMM RAM) to keep things warm. On hot days I have to have fan running and use my MacBook Air as it's too hot to do anything else! This is in the UK too, not Florida...

2x rx2600 1.5GHz/6.0MB with dual PSU, 16GB RAM run here in my basement.
They are, for their size, the fan-noisiest of the boxes. I have a rack
with 2xDS20Es (dual PSU) and 2xDS40s (triple) which make significantly
more noise at first power up but then the volume subsides. There are a
number of other things running here as well. In winter, my basement is
a comfy 76F (25C) without air. In the summer, unless some appreciably
long heat-wave hits, these run and don't tax the 3ton air-conditioner.
The electric bill, of course, heats me up when it arrives.

I'm using aha-2940uw adapter on my DS10.
You need to add the following lines to SYS$SYSTEM:SYS$USER_CONFIG.DAT:
--- cut here ---
device = "Adaptec AHA-2940UW"
name = PK
driver = sys$pkadriver.exe
adapter = PCI
id = 0x81789004
boot_class = DK
boot_flags = HW_CTRL_LTR, UNIT_0
flags = SCSI, PORT, BOOT
end_device
There you go, replete with the data for SYS$USER_CONFIG.DAT.
Also I have patched OVMS 8.4 CD which supports this adapter.

First, plug them in and see. If VMS can detect them, it will configure
the driver for and use them. You may need to add some device specific-
ation to SYS$SYSTEM:SYS$USER_CONFIG.DAT for this to happen. It will all
depend upon what chips are used on those controller. DEC did rebrand a
few Adaptec devices as well.

I couldn't be happier with the DS10L's performance (mine is the one
Rob's been using). It does make a little too much noise, but even the
missus has become used to it being on the whole time in our study. It
also running with a shadowset on the system disk, which does noticeably
slow it down.
I don't find the DS10L I have here to be too onerously loud. It's extremely
quiet compared to some other kit here.
A shadow set system disk should not slow things down. What disks have
you combined to form this shadow set? If you want to slow it down, put
the system on an IDE which the DS10L provides support for!!!
I'd like an itanium, but I haven't heard of one which is reasonable
enough on the power front to warrant being on for extended periods of
time. The DS10L is around 180W, which is not *too* bad.
I'll have to plug in my watt meter and see just how much my Itaniums do
actually consume; however, bang (CPU speed) for the buck (power use), I
would wager that the Itanium is better.

There are two scsi controllers on the pci bus and one of them is named PKD0. So I knew there had to be a PKB and PKC somewhere. I just located them on the motherboard... Never noticed them before!

One of the Qlogic 1020 or 1040 based KZP should be easy and cheap to find.
You don't want the KZPBA-CB though as it's HVD.
