I was using cheapo Aero 7 Lite fan speed at mid
I got SLK947 /w Ventec Sealth with shroud
much quieter but runs hotter 2~4c
I thought bigger, all copper heatsink would surely make up for the slower fan
guess not?

Airflow rules all... The slight difference in surface area of a heatsink is not competition for considerably different level of airflow.

You need a lot of surface area to make up for a smaller change in airflow. ;)

Another fan you might consider (if you live in the U.S, I'm not sure if it's avail. anywhere else... although I'm sure you could find something comparable) is the Delta HHE, it puts out almost as much air as a 80mm Tornado and is over 10dB quieter. With a fan controller, you can turn it down until it's just a low hum.

Like some of the Panaflo's, it's a high pressure fan ( I think it's comparable to the Panaflo U1A)... I'm not sure how it compares to the fan Mr.Radar recommended. Good luck with your cooling :)

Add me to the 'need high airflow for TR sink' group. Their design (SLK and SPs) is such that its benefits don't materialize unless you're pushing lots of air through them, although I think that the new big (make that huge) aluminum one works better than previous ones with lower airflow.

There is a thread in this forum where one of the members used two fans, sucking air, instead of pushing it, and he claimed better results that way. He used a duct to transfer the hot air out. Even then, I think his two fans were either 92mm Tornados or Panaflos, resulting in lots of airflow.

Yeah, I know who your talking about, but I forgot his name. Seem like a good idea to have "two" fans instead of "one". Might try that someday.

I don't know about some of you guys but with my SLK800U I get way better overall temps sucking from the sink rather than blowing.
