Case Cooling and Conclusions
Case Cooling

One of the Hiper’s main claims for their Osiris enclosure is an innovative airflow design that results in excellent case cooling with minimal noise.  The Osiris uses one intake fan (front panel) to pull cool room air into the enclosure.  In the process this fan provides direct air cooling for all the HDDs.  Two more case fans are used to exhaust the warm internal air out the back and top of the enclosure.

This is a pretty standard fan arrangement for a mid-tower enclosure (except for the bottom mounted PSU with its own dedicated air intake) and does a good job of providing adequate airflow while keeping the noise down to acceptable levels.  The following table lists the noise generated by the three Osiris case fans while operating at different voltages (speeds).

Note: Sound Pressure Levels were taken 3’ from the front, left-side of the Osiris enclosure with all three fans running.  The ambient background noise level was approximately 28 dBA.

At full speed the fans are far from silent but not too loud.  Slowing the fans down with a fan speed controller quickly reduces the noise to a whisper and at low speeds the Osiris becomes virtually silent while still keeping a little air moving.

Final Thoughts and Conclusions

The Hiper Osiris mid-tower enclosure is a nice looking case that delivers good airflow with acceptable noise.  The all aluminum chassis is sturdy and light weight.  The relatively compact chassis provides room for five 5.25” external devices and up to five internal 3.5” HDDs.
