(week long strip on Pirates vs. Ninja)
Okay, just finished my Ninja that I got today...
1. This thing is a bitch to install. The only aftermarket heatsinks I've used have been the bolt-through method, so I'm not used to the normal clip mount for 478. My heatsink came off while attemptiing to install it, I've heard this isn't good for the thermalpaste, once you put the H/S on, you shouldn't take it off without replacing the thermal paste. Anyway, I finally figured out it was easier to use a screwdriver instead of my fingers to push the latches down. I was scared I cracked the core, as I'm not used to having to put this much force on installing a heatsink, but it went on fine.
2. It's light. All of the weight in in the bottom, the aluminum is really thin.
3. I'm not testing it with CPUBurn, as I believe in real world testing instead of artifical benchmarks (ex: I've found the Raptor to be no faster than a 7200rpm drive, despite what the RoXxOr benches say). Running 3dmark2005, with a 9800pro, the CPU maxed out at 59C with an undervolted Nexus 120mm case fan (don't know rpm offhand). With my 900u with a Nexus 92mm at 5v, my CPU would max out at 71c. So, definite improvement.
Also, keep in mind this is next to a passive Phantom, while Mike's test was with a P180, separated from the PSU, with an additional blowhole (when one fan was turned off in the test, was the blowhole covered up, or left open?). So, due to this reason, as well as due to possible lack of good contact with the thermalpaste as mentioned above, someone who's better than I at installing standard 478 heatsinks might get better temps with a comparable processor.
In short, with the exception of a lack of an option of bolting it through the mb (like with some of the older thermalright heatsinks), I give this two thumbs up.
Now I'm going to switch out the Zalman(tm) 9800pro fan with th
e Nexus fan I just removed from the old heatsink.
*Edit* I forgot to mention, the 71C temp was while I had a Geforce2 in my computer, while waiting for my 9800pro to get repaired by ATI. I just got it back yesterday, and unfortunately didn't make a point of stress testing the CPU. Still, with the higher heatoutput, I imagine it shows how good the Ninja is, considering the load temp is 10C lower than with the old H/S next to a much cooler video card. *Edit*
