Apack's ZeroTherm BTF80 and BTF90 were hard to take seriously when
they first showed up at the SPCR sound lab. A heatsink shaped like a butterfly?
It's a joke, right? They look too frivolous, they can't possibly be any good.
No joke. Silly as they might look to some, these CPU coolers are serious efforts. Just
think of the shape as a means of differentiating the heatsinks for the dozens
of other high-end heatsinks out there. If ASUS can sell a
heatsink that resembles a jet engine, why can't Apack sell one that looks
like a butterfly?
Viewed from the top, their profile looks distinctly like a butterfly.
There's little question that the effect is intended.
As far as we know, this is Apack's first foray into the the retail heatsink
market. The Korean company has a background in making heatpipes and CPU heatsinks
for the OEM market. It has business relationships with several major players,
including Samsung, LG, and Intel, and appears to have money behind it. Unfortunately,
distribution in the English speaking world seems practically nonexistent at
the moment, but hopefully that should change with time.
There are two versions: An all-copper model for those who feel they need a
little extra performance, and an aluminum-finned model for those worried about
weight. According to Apack's specifications, the copper version is slightly
more efficient than the aluminum version, raising the cooling capacity from 140W
to 150W.
If the butterfly shape wasn't enough, the slick retail packages should tell
you that this heatsink isn't destined for the OEM market.
Neatly and safely packaged in a plastic blister pack.
Brackets for Socket 775 and K8 systems (including AM2) are included.
