Frequently Asked Questions - Grandis 3 SilentiumPC
Is the SilentiumPC Grandis 3 compatible with Intel LGA 1700 and AMD AM5 sockets?
Yes, the Grandis 3 supports Intel LGA 1700, LGA 1200, LGA 115x and AMD AM5/AM4 sockets. The included universal mounting kit covers all current mainstream platforms.
How do I install the cooler on my CPU?
First attach the backplate behind the motherboard and secure the mounting bolts. Then apply a small amount of thermal paste on the CPU, place the cooler on top, and tighten the screws. Finally connect the fan to the 4-pin PWM header.
What is the maximum TDP the Grandis 3 can handle?
The Grandis 3 is rated for a cooling capacity of up to 220 W TDP, making it suitable for high-end desktop processors even under heavy loads.
Can I add a second fan to this cooler?
Yes, the heat sink includes a second fan mount. You can install an optional 140 mm fan with a 4-pin connector. The included fan brackets hold an additional unit easily.
How do I reduce noise from the cooler?
The fan is PWM controlled, allowing the motherboard to regulate speed based on temperature. You can set a silent profile in the BIOS or use software to lower the maximum RPM. Also keep the fins clean for optimal airflow.
What maintenance does this cooler require?
Periodically remove dust from the aluminum fins and the fan using compressed air or a soft brush. We recommend cleaning every 6 months to maintain thermal performance.
Does the Grandis 3 have RGB lighting?
No, the Grandis 3 is designed without RGB lighting. It comes in a matte black or white version, focusing on pure performance and minimal aesthetic.
Is the warranty transferable if I buy it second-hand?
SilentiumPC offers a standard 2-year warranty for the original purchaser. For second-hand units, warranty coverage may not be transferable unless you have the original proof of purchase.
What should I do if the fan starts making noise?
First check if any cable touches the blades. If not, the bearing may be worn. The replacement 140 mm fan can be ordered through SilentiumPC distributors. Follow the instruction manual to replace it safely.
Does the cooler come with thermal paste pre-applied?
Yes, the package includes a thermal grease syringe with high-quality compound. You need to apply a pea-sized amount manually before installation.
