Hmm, let me think... aluminum heatsink and a higher price.

I think I'll be sticking with my Aero 7+

I seem to remember people talking about the hybrid heatsinks with aluminum and copper. The problem with all copper is that is accepts heat very easily but that means it makes it difficult to cool down effectively. So they use the copper over the core to spread out the heat and then aluminum to catch the heat from the copper and be able to lose the heat to the fan much more easily.

I could be completely wrong about this, but I think that was the rationale.

you are right on there Wolfie. i find that the copper cored/aluminum finned heat sinks work well...if they are of good quality. the vantec aeroflow (http://www.thetechlounge.com/review.php?REVIEWDIR=vantec_aeroflow)is a good example of this. it does a good job of keeping up with the aero 7+, my vantec acutally works as well as and sometimes better than rich's aero 7+ in my machine with the same chip and mobo. but his case is different . O/C'd barton 2500 never goes above 43C under load in my case...190 fsb, 11x mult.

in my opinion, the vantec aeroflow cu/al heat sink is one of the best cu/al sinks on the market. if you can't go all copper, it's a good alternative. plus it's smaller than the aero 7+, so it's easier to install on the A7N8X. i had a coolermaster copper cored aluminum sink once, work moderately well, but not as well at the vantec version with the pass-thru fins.

i love the aero7+ though too. but i can't see spending over $40 on the jet 7.

oh, and btw, the jet 4, the P4 version comes with an all copper base...someone explain that one too me. i would figure that the AMD version would need better heat transfer. go figure.

Even looking at the stats given on coolermaster's website. They seem to be almost the same (a little more cfm for the jet, 20 v 22) and the difference in heatsink.

I think they went a little overboard on the whole "Ooo Shiny" and forgot to make the cooler better. My Aero 7+ has a hard time fitting on the mainboard I've got now, I'd hate to see the Jet get on there.

Oh well. I guess I'll wait and see if they come out with something much better.

Interestingly enough, the Jet7 appears to run a bit higher in the RPM range than the Aero 7+. I think all the extra plastic actually retards incoming airflow thus reducing its effeciency. I think I will stick to the Aero 7+.

The Jet 7 looks great but the most sinister part about it is that the fan unit holds a considerable "charge" and for some reason, once I increased the fan speed, my new Athlon XP 3200+ popped like a firecracker and I had to run and have it replaced. I'm a bit afraid of this fan. Can you tell me more?

the jet didn't work as well because it was starved of air by the two 80mm exaust fans. a blower sucks air in on both sides and the fans were struggling with the jet for air.
