Ah, didn't read that bit. However Arctic cooling do make a low profile quiet
cooler I believe.

its called lapping... usually persons who Overclock do this.
They want 100% contact. The Thermal Paste that is placed between the heatsink
and the CPU usually cover minor imperfections....and most heatsinks have those.
My Thermalright heatsink consistently places in the top 3 in cooling performance
and each review states that the bottom is not level... Go figure!!

the Thermalright unit has a good reputation and if you need more quiet
you can change the fan.

Figure a 80mm fan at the lower or among extant standard fan sizings.
Have one, orange and may be a Thermalright fan, that's simply
adjustable -- there's added control knob connected to the CPU fan to
twist away at your noise tolerance levels (2000-5400rpm would be
within orders, 2000 being a whisper to your ear). Knowing the heat
and performance characteristics of the CPU would be my final
determinate: An adequate fan being one that does the job without the
computer randomly rebooting during stress. I used it for awhile,
anyway, on an all-aluminum Antec LanBoy for venting tunneled-air in or
out to the CPU after I'd drilled a rather large hole precisely into
the plexiglass side. No cracks in the the plastic radiating off the
hole yet is precise, right? End cooling effect, actual benefits
gained, wasn't worth writing home to mom about in my estimation: Leave
good engineering/planning airflow characteristics to the pros
designing good equipment, instead of randomly attempting to drill
holes in oceans of air. Then, again, I still also have that same speed
variability on the actual heatsink, itself. Bit hard to describe the
heatsink, unusual at the time -- size of a grapefruit with a
permanently incorporated fan, both being the squirrel cage-type,
cylindrical, with the fan inside a mass of copper fins. Precision
tooled equipment or poorly designed equipment for certain exasperation
go hand in hand with having cake and eating it;- something along the
classic line, you want it good and cheap? Also right - there's seldom
getting away from specs/reviews/rankings - even at important elemental
levels;-- only don't expect lapping, because it got lost on the
wayside somewhere along when topnotch thermal paste compounds began to
augment a burgeoning, better-than-factory aftermarket of OEM CPU
heatsinks.

That is a heatpipe cooler and usually in such a cooler there is a liquid inside
the Copper Pipes. The liquid heats and rises ,cools and fall and the cycle
begins again.
So cutting the tips off is not advisable
