Support & FAQs 

Caution: Tighten the screws until they stop.

Caution: Make sure to use the correct holes on the mounting bars.

Fix the mounting bars using the 4 thumb screws. 

Step 5:

Applying thermal paste

If there are residual traces of thermal paste or thermal pads 
on your CPU, please clean them off first. Then press a small 
drop (4-5mm diameter) of NT-H1 onto the centre of the heat-
spreader. 

Caution: Applying too much thermal paste will lower the heat 
conductivity and cooling performance!

Step 6:

Fastening the heatsink to the CPU

Caution: Please take off the protection cover at the bottom side 
of the heatsink first!

Put the heatsink onto the CPU and screw it to the screw threads 
of the mounting bars.

Caution: Tighten the screws until they stop.

Caution: Make sure that the curved sides of the mounting bars 
are pointing outwards.

Connect the fan to the mainboard, power supply or fan con-
troller.

Depending on your CPU and the temperature inside the case, 
you may interconnect the supplied Low-Noise Adapter (L.N.A.) 
or Ultra-Low-Noise Adapter (U.L.N.A.) in order to further re-
duce the fan’s operating noise. 

Caution: When using the (U.)L.N.A., check the temperature 
of your CPU using appropriate software (e.g. the respective 
applications of your mainboard manufacturer), in order to 
evade automatic throttling of the CPU due to the increased 
temperature. 

If the cooling performance is insufficient, please increase case 
ventilation or remove the (U.)L.N.A. 

Attaching the fan

Step 7:

First stick the 4 anti-vibration pads onto the cooling fins in 
order to dampen minor vibrations emitted by the fan. Then 
attach the fan to the heatsink using the 2 steel clips, placing it 
so that it blows onto the heatsink.
