Price: $15.00 USD


Introduction
Today we’ll be taking a look at one of spire’s latest heat sinks, the WhisperRockIV. The WhisperRockIV is a silent cooling solution, for the AMD socket a platform. This cooler is targeted towards the mainstream user, looking for a silient CPU cooler. Today, we're going to be comparing it against two other heat sinks, one tough competitor being the Coolermaster Areo 7+. Founded in 1991, the company gained AMD and VIA approvals along with recognition by International Standard Commission for Quality Assurance in 1999 against ISO-9002 and ISO-9001.

In-Depth Look
 

The WhisperRockIV is an aluminum/copper hybrid heat sink. Copper is better than aluminum at removing heat from a source, but it cannot get rid of the heat as fast as aluminum. This is why many heat sink manufactures have opted to use a copper core insert with the fins and the rest of the heat sink being aluminum. Spire is all about making a quiet cooler, and the WhisperRockIV is no exception.



The blue 80mm fan is rated at 25 dba while pushing out 28 CFM. The fan is rather slow, spinning only at 2300 RPM at most. The fan has no fancy LED lights or anything of that nature, but it does include a standard fan grill. The base of the heat sink came in a protective cover to prevent scratches to the core. Beneath the protective cover there was thermal paste covered by plastic film. Of course we will be removing their thermal paste and replacing it with our "AS 5"
