I know nothing of water coolers so I can't comment on that, and I don't know
about a pipe-style heatsink either. But I wonder about this: you have a
front-mounted fan blowing in. Now if a side fan was installed that
essentially blows in at 90deg to the front fan, I'm wondering whether some
of the side fan pressure, as its flow bends sideways when it hits the MB,
will splash forward and that backpressure may actually reduce the flow of
that front fan. Something to think about. Other components on the MB
probably don't need additional cooling since those components are spread
out, whereas the CPU has to dissipate 130 watts emanating from a very small
space, and maybe the graphics card which also generates heat. Some mfgr's
funnel onto or away from the CPU (I've seen Dell and HP funnel away). Or
perhaps that side fan could/should be another exhaust (just guessing, I
don't really know). What if you had two front fans? The top and rear exhaust
fans are probably perfect. Hopefully your CPU fan/heat-sink combo are sized
correctly.
Just a few more thoughts, not to run this into the ground too much!

Lee,
Yes, it is a Desktop with stock fan in front blowing in over the hard
drives and on up top blowing out. About the 12" fan, I tried to lower
the temp by removing the side cover and taking my table top fan and
pointing it at the inside of the case blowing over the motherboard and
CPU but that only kept it from peeking above 87 keeping it down around
83. The case does have optional mesh cutouts for adding fans 2 more on
the side cover that would blow right on the MB (just like mt 12"er and
one more location on the rear. So I ask myself do I spend $30 on 3 more
fans and connectors and $50 plus on a pipe style CPU heatsink or just
spend $79 bucks on a cooler. I read over on the gamer sites some say
the pipes didn't help all that much but every water cooler did the job.
If I was only going to do 1 or 2 minute clips for you tube I might not
worry so much but running at 85C for 1 or more hours at a time I'm a
little worried about that.
