This review shows the TRUE beating the CoolerMaster V8 on both temps and noise. For example TRUE gets 14.9 degrees difference between CPU and room, with 29.7 dBA, while the V8 gets 22.5 degrees difference using the same Nexus fan, with 29.8 dBA. That is, the TRUE keeps the CPU 8 degrees cooler.http://www.pcper.com/article.php?aid=648&type=expert&pid=6
This review shows the NH-U12P matching the TRUE in most benchmarks, and beating it in some.http://www.anandtech.com/casecoolingpsus/showdoc.aspx?i=3268
Still, I don't think you need to worry. These 3 coolers are all exceptional performers. You'll be pleased with the V8, I'm sure.
