Our test setup is as follows:
- Biostar TZ77XE4 Motherboard
- Intel i7-3770k
- 8GB Samsung low-profile DDR-3
- Enermax Platimax 1200W PSU
- Kingston 90GB SSD (OS)
- WD Blue 160GB HDD (storage)
- ASUS 24X DVD Burner
- HSPC Top Deck Tech Station
- Windows 7 64-bit fully updated
All tests are run using Arctic Silver Alumina thermal compound for comparison purposes. The CPU and heatsink is cleaned with Arctic Clean and Arctic Silver Alumina is reapplied. Tests are run at stock (3.5GHz [with 3.7GHz Turbo Boost]) and a moderate OC at 4.5GHz (no Turbo Boost). The system is left to idle for 30 minutes and a baseline temperature is recorded using CoreTemp. A Prime 95 blend test is then run for 30 minutes and the temps are recorded again. The recorded temperature is the average of the 4 cores. Since ambient temperatures can affect CPU temperature readings ambient temps are recorded during idle and full load testing. The ambient temperature is then subtracted from the recorded CPU temperatures resulting in a Delta T measurement, (or how many degrees above ambient the CPU cooler keeps the CPU). This levels the field for different ambient temperature tests.
Under stock clocks the Ereboss performed admirably. It came close to the similarly-priced SilverStone AR01 and only a degree behind the more expensive Noctua units.
With the heat turned up, the Ereboss came within a degree of the AR01 and within a few degrees of the Noctua units with their LNA’s installed. It’s cooling performance sits firmly in the middle of the pack, but it’s performance does reflect its price-point.
Let’s wrap up this review of the Raijintek Ereboss now.
