Sorry for the delay, “Things to do and people to see.”
Anyway, I can't find a good reviews anywhere for this thing. Only one out of the six that I looked at had the ambient temperature given. To me, that is annoying when you are looking for objecive conclusions and the review has nothing but ending temperatures. I like seeing the before, after, the C/W, the processor (with or without an overclock... as long as it is sprcified) and the fan or fans used in the test.
Anyway, the one I found that had the before and after temps.

As you can see, they took a P4 2.4C which under normal circumstances is putting out 69.0 Watts. By overclocking it to 3.0GHz it would most likely be at 81.9 Watts.
That being said, now lets look at the before and after temps.
Ambient: 25.0 C
Load: 42.5 C
Peak/Max: 45.0 C
If you look at the <A HREF="http://www.1sweetpc.com/reviews/heatsink/slk948u/page2.php" target="_new">picture here</A> you will see that the fan is most likely a <A HREF="http://www.thermaltake.com/accessories/dcfan/smartfan/a1357.htm" target="_new">Thermaltake Smart Fan-II</A>. The fan can give 75.7CFM at 4,800RPM and 48dBA. It is a great fan for an 80mm fan. I was happy to see that they used a real (normal) fan for the test. Unlike the beast that is "Stock,"
the Delta Electronics FFB0912EHE. It is 199 grams, has two axial fans (Dual sets of fan blades), and does 110.18CFM and 55dBA.
I will use the maximum figure, because it is the most that your CPU will throw at it so anything less would be at safer levels. In this example the C/W would be 0.244.
That isn’t bad but the Swiftech with the <A HREF="http:// http://www.q-tech.hu/pdf/SanyoDenki/DC_fan/092mm/1022057569.pdf" target="_new">Sanyo Denki</A> would do 0.220 C/W and it would be 12dBA quieter.
Just to be fair to the heatsink, I will assume that the ambient temp from the review at <A HREF="http:// http://www.cluboc.net/reviews/heatsinks/thermalright/slk-948u/2.htm" target="_new"> http://www.cluboc.net/reviews/heatsinks/thermalright/slk-948u/2.htm</A> was the same as the ambient in the 1sweetPC review.
They used four different fans. Let’s see how it did with each of the fans.
Y.S Tech TMD 70mm – C/W = 0.330 (0.329670)
Cooler Master LED 80mm – C/W = Same as above - 0.330 (0.329670)
Papst 3412-NGL 92mm – C/W = 0.31746
Vantec Tornado 92mm – C/W = 0.25641
Again the Swiftech does better than it with all of these fans.
It is like I said before. It is hard to look at cooler reviews because they don’t give enough real information to help you make an intelligent choice of which is best.
I hope this helps.
Got a LAN Party that you want people to know about?
Let me know about it.
