Don't put it into a 2U case, rather use a 3U case. I had much problems with the BBU temperature during high IO and CPU usage. Temperature went up just a little bit and syslog told me "Battery temperature HIGH" after a few minutes. HIGH means 45°C to 50°C, everything above means "TOO HIGH" which deactivates write cache. Using a 3U case solved this problem and everything works as expected, even when the system is totally busy with IO and CPU.
