Innovation Cooling – Diamond 24 Review

A few weeks ago Innovation Cooling began a survey on our forum concerning Diamond 24 carat thermal compound by giving away 100 syringes to Tech|Inferno forum members who have registered prior to June 26th in order to test it against thermal compounds they have already installed and use on their computers.

According to Innovation Cooling, Diamond 24 Carat Thermal Compound maximizes thermal heat transfer between the CPU core and heatsink by taking advantage of diamond’s superior thermal conductivity. Purified synthetic diamond has a thermal conductivity of 2,000-2,500 W/mK compared to 406-429 W/mK for pure silver. Diamond’s five times better thermal conductivity compared to silver makes it a superior heat transfer material for cooling high performance CPUs and is electrically non-conductive and non-capacitive.

In each tube of IC Diamond 24 Carat Thermal grease there are 24 carats of micronized diamond with diamond particle loadings @ 92% 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.

Key Features

• Superior bulk conductivity
• Excellent thermal impedance
• Tight particle distributions
• Silicone free
• Lower viscosity
• Greater stability
• Non capacitive or electrically conductive
• Thermal Conductance: 4.5 W/m-K (data acquired with an ASTM D – 5470 thermal interface test instrument)
• Thermal Resistance: 0.25oC-cm2/W@ 100 µ BLT
• Average Particle Size:
• Compliancy: RoHS Compliant.

IC Diamond is designed for stability and it will not bleed or separate in normal use. The curing time IC Diamond 24 requires is minimal and in most cases it will reach peak performance after two hours of use (optimized pressure of 50 PSI since lighter load pressures will increase cure times to a week or more)

The existing results from other surveys seem very promising

therefore I could not pass the opportunity to test ICD 24 against Arctic Cooling MX-4 used on my Alienware M17x-R2′s CPU and both GPUs along with a couple of other laptops that I was able to acquire for the occasion.
