$30 will get you an enclosure with a fan on it.
AMS DS-309SU 3.5" Black USB 2.0 External Enclosure

That one, has an 80mm fan integrated into the lid. Which is
both a plus and a minus. Unlike disk enclosures that come with a
40mm on the back, an 80mm spins slower (less obvious noise).
But, if the 80mm wears out, you can't replace it as easily as
the cases that come with the tiny whiney 40mm in it. The
ones with a 40mm, the 40mm unbolts for easy replacement.
In fact, I change out the 40mm on enclosures, as soon as
I take delivery :-) I put a quality ball bearing fan in
its place (purchased from a local electronics store).
I've had 40mm fans on enclosures wear out, in as little
as one day of usage. One 40mm fan, had a pool of oil sitting
below it, as proof the manufacturer tried to keep it quiet
with liberal doses of oil.

You can always just cut a hole in the current enclosure, and add a fan to
it. For example, right now, as I type, a four wire cable snakes
from my computer, to an 80mm fan. The 80mm fan blows over my
ADSL modem (has inadequate cooling). I only run the ADSL modem,
while the computer is powered up, and that's how I keep it cool.
The four wire cable, comes from a disk drive power connector.
You could also get power (+12V) from inside the disk enclosure, if
the drive type is 3.5". A 3.5" drive needs 12V, which is also the
voltage a brushless DC cooling fan would use. As long as the
fan has modest power requirements, it shouldn't overload the
wall adapter.
I used a Vantec Stealth 80mm for my cooling project. But you should
also have a pile of adapter cables and the like lying around, to
connect things like that up. You can see in the picture here,
this one comes with a "daisy chain" power connector, which
works for some situations where you need cooling. But you won't
know what power connections are available inside the WD enclosure,
until you open it.

(That one uses 80ma of current from +12V, which is pretty low.)

If you just remove the casing, and leave the raw drive sitting
in the room air, you might see 35 to 40C or so temperatures. Which
is fine, if the room air is dry (below 60% R.H.). Air above
60% R.H. causes the carpets to mildew, and that's how you'll get
a rough idea of the humidity. Using the fan will drop you below
35C.
