Direct-die mounting
This is a water cooler for direct-die mounting: the coldplate is mounted directly on the CPU chip, with no heatspreader in between. To do this, the processor must be delidded and the Integrated Loading Mechanism (ILM) of the mainboard is removed. Thermal Grizzly's Delid-Die-Mate is the tool for the 13th and 14th Gen chips. The cooler replaces both ILM and heatspreader, because it also does the job of a contact frame and presses the processor into the socket. It rests only on the threads for the ILM screws, mounted in such a way that its outer edges do not rest on the motherboard.
Nickel-plated microfin cooler
The microfin cooler is made of nickel-plated copper. Its cooler surface is equipped with a jet system, and the cooling channel slot width has been optimized to 0.25 millimeters. Compared to the standard version, the Pro version carries 50 cooling fins instead of 35 and offers a lower flow resistance. The nickel-plating of the cooler plate creates a barrier layer, so that gallium-based liquid metal cannot diffuse into the copper. Because of that layer, multiple applications of liquid metal such as Conductonaut Extreme are generally not necessary.
Acrylic glass, aluminum cover and RGB lighting
Between the coldplate and the cover made of anodized aluminum sits acrylic glass. After milling it is subjected to an annealing process, which relieves the material of internal stresses. This ensures that no stress cracks form even after a long period of use, as can occur with tempered acrylic glass. RGB LEDs are located under the aluminum lid and are controlled via the mainboard, through a 3-pin ARGB header (+5V/DATA/GND). They illuminate the acrylic glass under the lid and the G1/4-inch connections in the lid. With two connections, the cooler takes two compression fittings, such as the DeltaMate 16/10. Color: black and silver.
Compatibility note
The cooler is compatible with the following processors:
- Intel 12th Gen CPUs
- Intel 13th Gen CPUs
- Intel 14th Gen CPUs
Thermal Grizzly keeps its CPU compatibility list available online and treats processors not listed as incompatible.
KryoSheet usage note
Thermal Grizzly has extensively tested the cooler internally in various scenarios. During development, the focus was placed on ensuring stable operation of the processor and memory. In its test series, KryoSheet combined with the cooler did not provide significant improvements in temperature and posed issues with contact pressure. Therefore, we do not recommend thermal pads, as their additional thickness significantly affects contact pressure, which can impact performance.
The internal contour of the cooler is optimized for liquid metal, which can be applied in a very thin layer, and a thin layer of TG Shield should be used to insulate electronic components. Kapton Insulation Sheets are a risk here: if the cooler rests on the sheet, the height difference may become too large for the CPU die to make contact. Thermal sheets such as Carbonaut between die and cooler may put excessive mounting pressure on the CPU, which can cause incorrect memory detection or memory instability.
Attention: delidding and warranty
This cooler is only for delidded CPUs, and the price of that is loss of warranty. Removing the heatspreader ("delidding") of a processor is at your own risk! Once the CPU is delidded the manufacturer's warranty expires, and damage caused by delidding is not covered by it. Taking the ILM off the mainboard may also invalidate the manufacturer's warranty of the mainboard manufacturer.
General notes on water-cooling products
- Do NOT use the cooler in combination with aluminum-based water-cooling components in which the coolant comes into contact with aluminum, such as radiators with aluminum tubes.
- We recommend suitable coolants that contain biocides and corrosion inhibitors and are free of particles that could restrict water flow or clog the loop.
- Before filling, the custom loop should be leak-tested with an air pressure tester (maximum 0.5 bar) for at least 1 hour. Our leak tester is here.
- After filling, the system should be checked regularly during the first 24 hours for possible coolant leaks.
- According to Thermal Grizzly's specification, the operating pressure must not exceed 0.6 bar. When using components from other manufacturers, ensure that their maximum operating pressure ratings are compatible with the system.
