Specifications

Each tube of IC Diamond Thermal grease contains 7 carats of micronized diamond with diamond particle loadings @ 94% by weight. Material loading above 90% is recommended as the best combination of rheological and thermal properties to minimize interface pump out due to thermal cycling.

• Excellent thermal impedance
• Tight particle distribution
• 40 u maximum particle diameter
• Silicone free
• Lower Viscosity
• Greater stability
• Non capacitive or electrically conductive

IC Diamond comes in a 1.5 gram tube, which in theory is good for at least nine installations. The actual weight though is not specified on the sringe, rather the weight was obtained from visiting the innovationcooling website.

Testing

Testing Methodology

IC Diamond compound was tested with a number of popular compounds, within a temperature controlled environment. Tests were undergone by using the fan speed and temperature method. I.E fans full-CPU idle, Fans Full CPU full load. Idle temperatures were taken after one hour of 100% CPU load using Prime95. The processor was then left to cool down naturally for 30 minutes and only then were the idle temperatures taken. All ambient Air temperatures were at 25.7c

The same application procedure was used on all test, by placing a small ‘blob about 5mm in size at the centre of the CPU and the weight of the waterblock was used to spread the compound evenly.

Testing equipment:

• Core I7 (C0 Stepping) CPU
• Watercool Heatkiller CPU block with backing plate
• DFI X58 T3EH6 DK motherboard
• Thermochill PA 140.3 Prototype (old 16mm fan spacing)
• 3X SHarkoon 140mm Mid-range fans 64cfm each
• 2X GTX 260 in SLI mode air cooled
• 3x1gig of DDR3 1866 ram @1.65 volts (Corsair Dominator Ram)

Bios Settings used through-out the test:

Gilgamesh reviews are open and honest about our BIOS settings. We don’t jealously guard our methods; rather we prefer to openly share them with our readers. This is in order for our audience  to repeat the same tests for themselves!
