Excerpt: When we reviewed the Scythe Mugen 2 in the December issue, we praised its performance and ease of installation but bemoaned its enormous size. But now that we’ve tested its cousin, the Scythe Kabuto cooler, we’ve learned to be careful what we wish for. The good news is that the Kabuto mostly forgoes the Mugen 2’s ample proportions. The bad news is that it also forgoes the easy installation and excellent cooling.
Pros: Better-than-stock performance; PWM fan is nice to see.
Cons: Poor performance; bad mounting bracket; high price. Scythe's own Mugen 2 does it much better.
