This does tend to suggest your case intake is insufficient,
but the stock heatsink should do better than this, I'd try
removal, cleaning CPU & it off, then applying fresh thermal
compound - just a tiny bit.

Ok, but how about the obstructions to flow from these fans?
The front bezel or mere holes stamped out of the case wall
make for a poor fan hole relative to a large open area.
Since we can't see your case, you'll have to determine how
much of a factor this is. Certainly at only 1000 RPM there
is some room for higher fan speed, but unless there is a lot
more hot-running hardware you haven't told us about, a pair
of 120mm fans @ 1000 RPM should be sufficient in keeping CPU
cooler than it is.
What about the room temp? We'll presume it is moderate, not
hot, (like under 28C) until told otherwise.

They must be measuring it at idle, is yours idle or at some
partial load? It doesn't really matter though, the temp to
focus on is that at full load. Even so, that yours is up to
68C in any state is already indication something needs done,
unless you suspect the board is reporting temps wrong - in
which case a bios update would be in order.

While it may seem that way, it increases case pressurization
which helps the rear fan exhaust at higher rate at any given
RPM, but of course for maximum effectiveness the air
passages have to be as unobstructed as reasonably possible,
an area where many cases fail miserably when one wants a
quiet system instead of fans at higher speed/noise to
compensate for a case weakness.
Looking at the front of your case, it looks very sleek, and
very poor for intake unless the entire front is a micro-mesh
too fine to be captured by the camera.

While it wouldn't look as good afterwards, one possible
solution would be to cut out a (slightly undersized)
120x120mm square hole, and put a black mesh filter panel on
the front. It also seems a shame to cut on the case though,
if you would rather put a fan in the side panel that may
work too, so long as you keep the front fan so there is at
least a little airflow past the HDD rack. Here's what the
mesh panels I'm thinking of look like, but I'm too lazy to
hunt down a black one at the moment, I think maybe
Directron.com, nexfan.com or Svc.com may have some... but
I'm sure a Google search will find them.

.... and of course it's not black but some are.

yes, but I don't think you need them and they will be worse
than a bottom front intake.

If you want the ultimate custom look, take a 80-92mm fan and
trace it's inside opening onto two of your bay blanks taped
together, then cut out the hole and mounting screw holes.
Next screw or glue the two blanks together to make them one
piece and put the fan in.
If the cut results in light metal showing up, you can get a
blackening pin used by gunsmiths to darken metal, or just
use a Sharpie Industrial marker (more durable than a regular
sharpie because it's lacquer based) to color that area
black, or put a filter panel on the front, but again I dont'
think you need this as much as more lower intake area- it
isn't as important where the air comes in as it is that the
air flow over as many parts as possible... remember that if
the air gets heated some before it gets to the CPU, that is
a good thing, it means the temps of the parts it passed over
are then lowered. If CPU is still too warm it signals a
flow rate too low, but I would remount the heatsink before
doing anything else.
