OCZ Tempest Heatsink Review
OCZ Tempest Heatsink Review
Abstract: After a long absence from all things heatsink related, OCZ is back in the game with a compact little multi-socket heatsink called the Tempest. The design relies heavily on copper components...

Information on Frostytech's test methodology is available here.

The Heatsink Fan:
The 95x95x25mm fan will spins at 2500RPM, with four blue LEDs behind the motor illuminating the translucent plastic impellers. The fan draws power from a standard 3-pin motherboard fan header, and it supports RPM monitoring. The seven bladed fan is attached to the OCZ Tempest heatsink on a quick release fan bracket. The tabs at the top and bottom release little clips that hook into the Tempest, making it really easy to upgrade or change a fan out.

Heatsink Top:
With the fan bracket momentarily removed we can get a better look at how the OCZ Tempest heatsink is put together. The nickel-plated copper fins are spaced ~1.8mm apart, which is pretty broad for a heatsink of this size. The wide spacing does allow the Tempest heatsink to be used with a slower RPM fan, like the 2500RPM model it ships with. The four 6mm diameter copper heatpipes intersect all the fins about half way up, and all joints are soldered for optimal thermal transmission. The copper fins span out over an area 90mm x 72mm in size.

Heatsink Side A:
From the side we can see how the four heatpipes rise up from the copper base of the OCZ Tempest heatsink, and out into the fins above. The copper fins are not really joined to the base of the heatsink, so the majority of all heat from the processor must be transferred by the four heatpipes. The entire heatsink stands just 78mm high. The nickel plated copper base is 5mm thick.

Heatsink Side B:
Shown here from the other side, the OCZ Tempest heatsink is clearly a cooler built for lower-RPM fans. The wide spacing between each copper fin offers little resistance to airflow, which is just the kind of environment you need to reduce fan noise. The quick release clips which hold the fan onto the body of the heatsink are also visible. It's one of those features that makes you stop and wonder why no one ever thought of it before. To install the Tempest onto a processor, mounting clips will first need to be attached to the base of the cooler from either side (not shown).

Heatsink Base:
The base of the Tempest heatsink is made from stamped sheet of copper which has been nickel plated, it is perfectly flat in both axis. The CPU mounting pad measures 50x36mm in area. Surface roughness is on the order of ~4 microinches, which is considered excellent. At either side of the base are holes for attaching the various socket mounting brackets.
