This heatsink seems pretty popular and apparently works quite well!
Overclockers Club Canada looks at the Thermaltake Volcano 7+.
Before I start, you guys are probably wondering: "Why would I review
a Volcano 7+ when there are superior models already out for quite some time
now?" Of all the reviews that I've seen so far on a Volcano HSF, I've yet
to find one that is tested against a Pentium 4 CPU. Even if a Volcano 9+ is
released, it will most likely be tested using an AMD processor, since up to
this point and a little beyond the latter CPU is the one that requires more
cooling power. Thermaltake also has another solution for the Pentium 4, known
as the Spark 7, but from what I know, availabilty on that particular item is
very low, and as such not very many people have actually heard about it. Because
of these reasons, I've decided to bring back an older item and put it to the
test using a socket 478 environment.
