RUBBER GROMMETS

The fan is decoupled from the frame by four rubber grommets. This is a selling point for Arctic Cooling that's well described in the marketing literature. Their purpose is to reduce the amount of fan vibration that is transferred to the heatsink and the motherboard, thereby reducing noise.

How significant is this? It is worthy of note. Only serious silencers are likely to notice it much, and the difference is likely to be subtle. But, in a properly built system it could be the difference between a quiet system and a silent one.


Tiny rubber grommets attach the fan to the frame...


...so that the fan hangs from the frame instead of being firmly attached.

INSTALLATION

Arctic Cooling provides a single bilingual sheet of instructions with the Freezer 7 Pro (German and English). There are seven steps to cover everything from removal of the old heatsink to the correct orientation of the heatsink to the actual installation.

The mounting system is the same as used by Intel's stock heatsink, so mounting the Freezer 7 Pro is fairly simple. Four white plastic fasteners are positioned at the four holes around the CPU socket on the motherboard. The black plastic head has to be in the most clockwise position. Then, each of the black plastic heads is pushed down to lock it in place.

It is important to make sure that each of the four pins is engaged tightly, and to the same depth. It is possible to have one or more of the locking shafts be only halfway engaged, yet still look and feel reasonably tight. If this happens, the base of the HS will not be sitting with even pressure on the CPU, and cooling will suffer.

The heatsink can be mounted in any orientation, so it should always be possible to set it up correctly with the fan blowing towards the rear of the case. Arctic Cooling recommends removing the fan before installation, then putting it back on after the HS is engaged on the motherboard.


The base is copper, and comes with thermal interface material pre-applied.
With the TIM removed, the base is flat and quite smooth, though not polished.
