Enzotech Ultra-X Heatsink Review
Enzotech Ultra-X Heatsink Review
Abstract: We might as well get to the point in the first sentence of this review, the Enzotech Ultra-X performs really well on Intel and AMD processor platforms with its fan at full speed.

Information on Frostytech's test methodology is available here.

The Heatsink Fan:
The 120x120x25mm fan is protected from errant wires with a wire fan grill. Noise levels hover around the 59.0 dBA mark at full speed, and go down from there. The fan speed controller is a little bit touch and go, so we wouldn't recommend using it. The fan connects via a 3-pin fan header.

Heatsink Top Uncovered:
Each of the four 8mm diameter copper heat pipes intersects the 66 aluminum fins at equal distances, dispersing the heat from the base evenly across the length of the cooling fins. The cooling fins occupy a footprint of 120 x 120mm. Each fin measures 0.3mm thick, and is spaced 1.5mm apart.

Heatsink Side A:
The four heatpipes are all equal in length to prevent the center of the Enzotech Ultra-X heatsink from becoming hotter than the outer edges of the aluminum cooling fins. The 8mm diameter copper heat pipes elevate the cooling fins 50mm above the motherboard where they are well out of the way of most nearby components, memory, or northbridge heatsinks. The fan blows air through these aluminum fins, directly onto the pin-fin forged heatsink below.

Heatsink Side B:
The Enzotech Ultra-X heatsink is a very simple design, but one that we have seen used very successfully by many different heatsink manufacturers. The Ultra-X logo is nicely cut into the side of the aluminum fan frame that supports the 120mm Delta fan above. The top portion of the heatsink is bent at a slight angle to the base, as you can see. The pin-fin heatsink has 2.4mm diameter pins that are 9mm high.

Heatsink Side C:
The base of the Enzotech Ultra-X heatsink is what holds it in place on LGA775 processors. While a spring clip applies pressure to the top of the black anodized aluminum forged heatsink, Intel CPUs require a different approach. The copper base is forged from C11000 copper, and the four tabs at either corner are rigid enough to support the full compressive force of four spring-tensioned thumb screws which thread onto the brass support stands from the base plate. The installation procedure is pretty straight forward, but you'll want to tighten each thumbscrew alternatively, like you would when putting a tire on a car.

Heatsink Base:
The forged copper base of the Enzotech Ultra-X heatsink is large enough to cover both Intel and AMD processor heat spreaders. The CPU pad is 54mm in diameter, with at least 3mm copper between the CPU core and heatpipes. The surface is perfectly flat in both axis, with a smooth polished finish. Surface roughness is on the order of ~8 microinches or less, which is considered excellent. The heatpipes are positioned closely together, occupying 33mm wide swath at the center of the heatsink. As you can see here, the base of the Ultra-X is not centered on the body of the heatsink.
