Eight Low-Profile CPU Coolers For Your Compact PC, Reviewed

EFZ-100HA2 Installation

White split pins on the Intel LGA adapter fit into mounting holes first, followed by black plastic tacs. This is the only cooler in today’s round-up that doesn’t require motherboard removal.

A look under the motherboard shows how the black plastic tacs wedge between the ears of those split pins to look the adapter in place.

The EFZ-100HA2 now clips onto the Intel LGA adapter in AMD style, using its original Socket 462 spring clip.

Because its fins are narrow and tapered, the EFZ-100HA2 has the best component clearance of any cooler in today’s test. On the other hand, that taper makes it hard for us to define its clearance in either inches or millimeters.

SilenX calls this a 100 mm fan, but its blades are an exact match to several 92 mm x 25 mm fans that we compared. Metric fan sizes are based on frame size, and the blade diameter of this frame-less fan is around 86 mm.

    Zalman CNPS2X conspicuous by its absence - 28mm tall cooler that claims to be able to shift 120W?

    There must be 2 winners
    Nocturna NH-L12 is best quality (Don't forgot about 6 ears of warranty)
    and Zalman CNPS8900 Quiet Smart Buy

    I'm a bit surprised by the Noctua offering, as they do have a much smaller only (37mm tall) but then I expect they wanted to use as much space as possible to ensure a good score.

    Also the NH-L12 I believe is compatible with Noctua's NF-A15 which is a 150mm PWM fan with 120mm mounting holes. In my perfect small form factor case I'd swap one of those as the top fan and just use a 150mm side vent as the only exhaust for the case, with other vents as intakes over the major components, or maybe leave off the top fan in favour of fitting an 200mm fan if space allows. That being for a high performance small case anyway, anything more modest I'd probably just go for the 37mm option.

    Another favourite option is Prolimatech's Samuel 17 cool (45mm) plus one of their 140mm x 15mm Ultra Sleek Vortex fans for a total height of ~60mm, which still tops out under 2.5"
