Frequently Asked Questions - CNPS8900 Quiet ZALMAN

Is the Zalman CNPS8900 Quiet compatible with Intel LGA 1700?

No, the CNPS8900 Quiet is not officially compatible with LGA 1700. It supports LGA115x/1366/775. For LGA 1700 you may need an adapter, but check with the manufacturer.

Does the cooler come with thermal paste pre-applied?

Yes, the CNPS8900 Quiet includes pre-applied thermal compound on the base for easy installation.

How do I clean the CNPS8900 Quiet?

Use compressed air to blow dust off the fins and fan. Avoid using liquids or solvents as they may damage the bearing or electronics.

What is the maximum TDP the CNPS8900 Quiet can handle?

The cooler is suitable for CPUs up to about 95W TDP, making it ideal for mainstream processors.

Can I replace the fan on the CNPS8900 Quiet?

Yes, the 92mm fan is replaceable. Use a standard 92mm fan with PWM and secure it with the provided clips or screws.

Is the CNPS8900 Quiet loud under load?

It is designed for quiet operation with noise levels between 18 and 30 dBA depending on fan speed. At full speed it is still relatively quiet.

Does the CNPS8900 Quiet support PWM control?

Yes, it uses a 4-pin PWM connector that allows the motherboard to dynamically control fan speed based on CPU temperature.

What are the dimensions of the CNPS8900 Quiet?

The cooler measures 110 mm x 110 mm x 60 mm, making it a low-profile design suitable for small cases.

How do I install the CNPS8900 Quiet on an AMD socket?

Use the included AMD mounting bracket. Align the cooler over the CPU, secure it with the screws, and connect the fan cable to the CPU fan header.

Is the Zalman CNPS8900 Quiet still a good cooler for modern CPUs?

While it's older, it remains effective for low-power CPUs and HTPC builds. For high-end CPUs, consider a larger cooler.
