Heatsink Test – Joe
SUMMARY: Attractive heatpipe heatsink – moderate performance.
The good guys at Evercool were nice enough to send a sample of their Sharks CPU Cooler to try out.
Key Features:
- Orange LED fan light
- Fan 80 x 15 mm; Two speed switch – Low Speed 2000 rpm, 18 dBA, 23 cfm; High Speed 3500 rpm, 28 dBA, 41 cfm
- Weight 460 grams
The fan sits in the middle of the fan array:
There is a switch on the top of the heatsink to switch the fan between low and high speed – not the most convenient setup.
The base shows no apparent polishing marks:
The heatpipes appear soldered to the base:
The Sharks 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).
| Heatsink | Case Temp | Ambient Temp | C/W | On-Die Temp¹ |
| Evercool Sharks, High fan @ 3515 rpm, 53 dBA² | 41.0 | 19.1 | 0.23 | 51 |
| Evercool Sharks, Low fan @ 2513 rpm, <50 dBA² | 45.2 | 19.0 | 0.28 | 55 |
¹MBM on-die temperatures.
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 the Evercool Sharks in the lower rank of heatsinks tested to date (Heatsink Ranking) with the fan at its highest speed setting. Performance at the lowest fan speed is not recommended under stress; at this setting, the fan is almost silent but noticeable.
Evercool’s Sharks is an attractive heatpipe heatsink with moderate performance – two fan speed settings are possible with a top-mounted switch.
Thanks again to Evercool for sending this our way to test out.
