Frequently Asked Questions - CNPS8700 NT ZALMAN

How do I install the CNPS8700 NT on an Intel LGA775 socket?

First, install the Clip Support and Backplate using the provided fixing bolts. Then insert the Clip between the heatpipes, aligning it with the Base Cover. Apply thermal grease on the CPU, then mount the cooler by sliding the Clip Lever onto the Clip's groove and securing it to the Clip Support's lug. Finally, connect the fan to the motherboard.

What CPUs are compatible with the Zalman CNPS8700 NT?

It supports all Intel Socket 775 CPUs (Core 2 Quad, Core 2 Extreme, Core 2 Duo, Pentium D, Pentium 4, Celeron D) and AMD Socket AM2/754/939/940 CPUs (Athlon 64 FX, Athlon 64 X2, Athlon 64, Opteron, Sempron).

What is the noise level of this cooler?

The noise level ranges from 17.5 to 30.0 dBA ±10%, measured at 1 meter distance. The fan speed varies from 1150 to 2100 RPM.

How do I connect the fan to the motherboard?

Connect the CNPS8700 NT's 4-pin PWM fan connector to the CPU fan header on the motherboard. Ensure PWM control is enabled in the BIOS for automatic speed regulation.

What precautions should I take during installation?

Do not exert excessive force on the fan or clip. Keep the product away from children. Avoid inserting objects into the fan while operating. If thermal grease is ingested, seek medical attention. Ensure no motherboard components taller than 39 mm are within 61.5 mm radius from the CPU center.

Can I overclock my CPU with this cooler?

Yes, but Zalman is not responsible for any damages resulting from overclocking. Ensure adequate case ventilation and monitor temperatures.

Is the CNPS8700 NT compatible with AMD sockets?

Yes, it supports AMD Socket AM2/754/939/940. No additional components are needed for AMD installation; simply use the motherboard's existing retention frame.

How do I apply thermal grease?

Clean the CPU top surface, then apply a sufficient amount of the included thermal grease (②) evenly on the CPU. Do not use excessive amounts.

What is the fan speed range and control method?

The fan speed is automatically controlled via PWM from 1150 to 2100 RPM ±10%. The fan uses a 2 ball-bearing and has auto-restart function.

Does the cooler cool components other than the CPU?

Yes, the airflow from the 110mm fan also cools the VGA card, Northbridge, FET, and RAM, improving overall system temperatures.

7. Installation (Intel Socket 775)

1) Clip Support Installation

Align the Clip Support for Socket 775(⑦) and the Backplate for Socket 775(⑧) with the mounting holes on the motherboard and fasten them together with the Clip Support Fixing Bolts(⑥). The Lever Slot on the Clip Support for Socket 775 should be properly oriented on the hinged side of the Socket Lever when installing.
※ If the Lug of the Clip Support for Socket 775 interferes with any motherboard components, install the Clip Support for Socket 775 with the Lug facing a different direction to avoid interference.

2) Clip Installation

Insert the Clip(③) between the Heatpipes. Turn the Clip so that the central hole comes in alignment with the Base Cover's projecting part. Now attach the Clip so that its central hole slides over the projecting part of the Base Cover. Do not exert any excessive force on the fan during the Clip installation. Excessive force on the fan could lead to product damage.
