Conclusion: I was very impressed with the results that I received from the Hyper 48. My temperatures dropped 11 – 15 (idle – full load) degrees Celsius from the temperatures that the system ran at while using stock cooling. The Hyper 48 was barely able to beat the Evercool HPC-925. That is understandable due to the fact that due to the fact that the HPC-925 has 6 heat pipes compared to the Hyper 48′s 4 heat pipes. Where the Hyper 48 excels is in its all copper construction.
