Thermalright SK6 Review with online sound

In this review we have tested the Thermalright SK6 Cooler and measured the temperature results with our test setup. Additionally you can listen to an embedded MP3 fan sound sample of the fan on the respective heatsink.

Description Thermalright SK6 Delta Black (also available in other versions)
Overall size in L/B/H +++ 73/63/58 mm The heat sink protrudes slightly beyond the base – see Fit for Fan
flow rate ++++ 37.6 CFM (6800 rpm)
noise level — 46.5 dB (A) It’s hard for me to compare, but you could compare it with a hair dryer at level 2 😉 Listen online:
assembly +++ The clamp needs quite a lot of pressure, but this is not surprising with a heavy heat sink and has a positive effect on the cooling result. Otherwise it’s easy to handle and you can hardly slip during assembly.
Cooling result ++++ A top cooling result ! 37°C at 1,75 Volt CPU voltage and only 40°C at 1,9 Volt Vcore with 1066 MHz !
Overall impression

+++ The 350 gram heavy Thermalright SK6 with the very strong and loud Delta fan shows even with high overclocking the top results expected from a full copper cooler. The heat sink is cleanly manufactured and comes with two clamps to mount higher fans. The assembly should be done in one minute for an experienced hobbyist and is extremely durable even without screws. The underside of the fan is unfortunately not polished mirror-smooth but only milled out, but who uses a good heat conducting paste, can easily compensate for the unevenness and gets a top cooler !

It is also suitable for Peltier elements ! Many thanks to Overclockers for the test pattern.
