The WhisperRock IV features a copper core, aluminum design. The WhisperRock IV is topped with spire designed fan guard and translucent blue fan.
A 3 prong clip is used to attach the heatsink securely to the CPU Socket. The clip design requires a flathead screwdriver to install, with ample area to fit most size screwdrivers without the risk of slipping and gouging your motherboard.

AMD heatsink clips are notoriously difficult in some instances. Spire has a very easy to manipulate clip here. I also like the fact that they meshed the fan wires. Nice attention to detail."- Overclock Intelligence Agency Read The Full Review

nice cooler
It’s pretty good and has brought down the temperature of my Pentium III-S 1.4GHz CPU down to 43C from 55C. It’s also much quieter than the stock Intel fan I used to have, but not as quiet as it advertises; sometimes, though, the fan’s noise changes as if something is loose and is vibrating in it, but I could not figure out what it is (it doesn’t happen a lot, only sometimes). The combination of heatsink+fan is huge, so make sure it fits in your case, especially if you’re using a low-profile, small form-factor case (like FlexATX).
I gave it a 4/5 because of the noise (not as quiet as it says)...

perfect fer any socket a (socket462) mobo
I loved this heatsink cooling fan combo, u get a huge fan with a huge heatsink convinient fer old mobo socket a(socket 462) it works fits and gave me no problems at all compared to my old amd fan its quite and on another note u get the heatsink thermal compound (thermal conductivity:>2.062W/m-k,thermal resistance:<0.06C-in/w)from spire.
