While I'm stress testing my hard disks using bad blocks and jgreco's scripts I would like to also use this opportunity to verify my cooling. The Cougar fans I'm using are only running at their slowest speed while running badblocks and the stress tests as on my SuperMicro X10SL7 the SuperMicro secret sauce for the fan controller for the FAN-A appears to be heavily influenced by the the CPU temperature and as the Xeon E1231v3 CPU is chugging along at 0.01 to 0.4% utilization it is not generating any heat. Meanwhile one of the disks is running at 39C and another hitting 41C occasionally.
I suspect that this low CPU utilization is low for a "Normal" FreeNAS box during this much i/o.

- Can anyone give me a benchmark for this CPU's utilization under more normal conditions that would generate this much disk activity (say under medium-high FreeNAS load - a scrub?)
- Anyone have any ideas on how to generate a similar CPU load under FreeNAS so I can see the resulting impact of the FAN-A PWM output and how well the cooling works then? (is "stress" included with FreeNAS and, if so, is texinfo also included so I can see the complete docs?)
