sammorris,
Basically all they do is control the amount of heat in a more precise way and then determine how much of it the cooler can remove. As you and I both know, life in the test lab and life under real world conditions are often not the same. When I see someone having heat problems using a TRU or a TRUE, I have to seriously question their cases airflow efficiency! When I see cases with 6 or 8 fans, still having heat problems, I have to question why! It isn't enough to just cool the CPU, but you still have to get all that heat removed from the CPU out of the case. The greatest CPU cooler in the world can't overcome that problem, as it still needs a supply of cooler air or the temps will go up!

Like I say - 600rpm case fans and my CPU runs full load at 42 degrees. So when I see cases with 2000rpm fans, I do wonder...

My cnps 9700 came with a perfect mirror finish (the one i got for 20 bucks).

They don't come lapped so someone did it!
Here's how the Enzitech looks:
I would call that Mirror Finish! LOL!! Works fine with MX-2!

Russ,
I still don't completely agree with what your defination of lapped or lapping is.

in machining, to "lap" means to polish an object to perfect flatness

I doubt that someone else lapped it because it was sealed with the Zalman seal and it didn't look like it was ever opened.... anyways, i uploaded a picture of it on my site (theres nothing else on there).

Mort81,
As I said in my previous post, the only one I've come across to date that wasn't flat was that Scythe. I polish them to a dull shine and it's still pretty easy to tell if it's bad. You can see the distortion in the reflection like I did on the Scythe. A steel ruler and a good eye works pretty good for that! I'm no expert, believe me. I just go with what seems to work best! Arctic Cooling just makes it easier for me by having very flat heatsinks and I use them about 95% of the time. Of course, now you realize that the next 6 I see will be terrible! LOL!!

I've seen heatsinks that pulled that off, but look really closely at them and you can see the imperfections. They're very slight, but they're there.

sammorris,
It's pretty simple. I check for flatness with a straightedge, and polish it if it's flat! If there's any distortions in the reflection, then it's not as flat as it could be! If it was real bad I would take it into the shop and surface it. Frankly, I don't see a lot of difference in my temps. I suspect that this is because my temps are very low to begin with.
As far as the debate as to whether a dull shine or mirror finish is best, my guess is that the mirror finish would be better, as that would present the absolute maximum unbroken surface contact area to the CPU heat spreader. I know someone raised the idea that if it was mirror finished it would squeeze all the thermal compound out, but that's not true as there's more than enough surface tension to hold the compound, so more than enough would remain to do the job, even with MX-2, which is thinner than most other compounds. I asked the the metallurgy guys at work and they all say the same thing, "the smoother the finish the better the heat transfer!
Best Regards,
Russ

I had to do my fans over again. With the side 80mm blowing in it took about a month for the CPU cooler to get all blocked up with dirt. A couple of days ago I started noticing my CPU temp was going up, and the Cooler was all clogged up. Of course I smoke, which doesn't help either.
Anyway, I'm back to one intake and two exhausts. My CPU temp went up about a degree, but the NB and video card run cooler as the static air vent on the side cover moves more air. The video card runs 3-4C cooler, but the NB temp is about 1C cooler. I only mention any of this because of people who live where there's lots of dust. The strobe effect of the rear fan's sound has disappeared completely and the computer is now as quiet as it used to be before I switched the fan to an intake! I'm now back to 1300 rpm for both the rear and side fans and about 100 cfm. After seeing the mess it made after only 1 month of running the 80mm as an intake, I'll never make that mistake again! LOL!!

sammorris,
The dust filter I put on the Intake works fine, but I didn't have one on the 80mm when it was an intake. I had to scrape the crud off of the HSF fan blade. I didn't really notice how loud it was that way until the other night, when I had an AutoCad test simulation running all night. I gather that was because the top of the CPU cooler and the fan are only about 3/4" apart so as an intake it made a lot more noise blowing against the top of the cooler!
I know originally one of the drawbacks to the 80mm being an intake was excessive dirt, I just didn't realize it would be so bad! LOL!! Next time I'll leave well enough alone! LOL!!
