ICYQ HEATSINK
The stock heatsink is quite conventional: No
fancy heatpipes or ducts here! Despite the fact that the system is based on
a Socket 939 design, the heatsink is mounted using a socket 478 retention module, a practice seen in a few other A64 SFF. This means
the user is free to replace the heatsink with an aftermarket design of his
choice. Compatibility will be limited by the clearance around the socket,
but there should be plenty of smaller heatsinks on the market that fit the bill.
The heatsink is a traditional downward-blowing design.
The heatsink is a hybrid copper-aluminum design that uses a copper core to
transfer heat away from the CPU core up though the heatsink. The core is slightly
smaller than the heatspreader on the AMD processor, which means some of the
aluminum fins also make contact with the heatspreader. The core showed some
faint machining marks, but nothing serious enough to warrant concern.
A copper core is surrounded by aluminum fins.
Removing the fan reveals that the heatsink is surprisingly small, no more than
four centimeters tall. The low profile is necessary to provide enough
space around the 80mm fan to ensure adequate airflow.
Tension is applied to the heatsink with a large lever that locks it into
place.
POWER SUPPLY
Unlike most SFF systems, the power supply in the EQ3901 conforms
to a standard form factor. The SFX12V v3.0 form factor is certainly not as universal
as ATX12V, but they are available commercially. Another advantage of the SFX12V form factor is its use of a standard
80mm fan, which means a quiet fan swap is viable if necessary.
Although the label is branded Soltek, the model number identifies the manufacturer
as Seasonic, who have products have been recommended by SPCR in the past. Most
importantly, the product
page for the power supply identifies the fan controller as being identical
to the one that we've praised in the past.

We did not test the power supply independently of the system as a whole. The
300W rating easily exceeds any load that we could realistically produce with
a system of this size.
