Heatsink Test – Joe

SUMMARY: Very good performance at low noise – a winning combination.

The good guys at Kingwin sent a sample of their
Kingwin RVT-12025 to test out. This is a three heatpipe heatsink with a relatively quiet 120 mm fan.

Key Features:

  • Three Heat-Pipes directly touching the CPU
  • 120mm Fan; Speed: 800~1500 RPM; Noise level: 20~32 dBA @ 72.1~99.6 CFM; Connector: 4 Pin with PWM
  • Heatsink Size: 120 x 50 x 159 mm; Weight: 600 grams (w/fan)
  • AMD: Socket AM2/754/939/940 CPU, Athlon 64/FX/X2, Opteron, Sempron
  • Intel: Socket 775 CPU, Core 2 Extreme/Quad/Duo, Pentium Extreme Edition/D, Celeron D

The RVT-12025 has a fairly conventional footprint:

The base shows one major difference to other heatpipe heatsinks – the heatpipes contact the CPU’s IHS directly:

This arrangement eliminates one thermal interface – that between the base and heatpipes – common to most -other heatpipe heatsinks.

The Test

The Kingwin RVT-12025 was tested on an Asus P5WD2 motherboard P4 Motherboard Test Platform with a modified Pentium D 805 to read CPU case temps (both supplied by Directron).

²50 dBA measured 8″ from the fan intake corresponds to about 30 dBA measured 3 feet from the fan, a very quiet noise level.

Results place Kingwin’s RVT-12025 in the upper rank of heatsinks tested to date (Heatsink Ranking) with the fan at its highest speed setting.

CONCLUSIONS

A nice package – relatively low noise and very good performance.

Thanks again to Kingwin for sending this our way.
