Manufacturer Website: Speeze
Speeze is the front end to an
established Taiwanese company called Fanner. an US based PC
peripheral manufacturer that has been up for more than 10
years now. Fanner have been around for a surprising
twenty-five years (that's six years older than the original
IBM PC!). They have been mainly involved in the OEM/ODM
section of the market, which is probably why you haven't
heard of them before. The products are also sold under the
name of Spire, Fanner(tech) or Bytecom depending on where
you live.
A brief outline
 The
5E32B3 is a traditional, low cost, all aluminium
design. It is a similar sort of build to other overkill
coolers such as the FOP3x. However the fan is much smaller.
It is a 60 mm 4000 rpm model, outputting 17.1 CFM. This is
rather disappointing; especially given the now infamous
delta black label (as employed on rival high performance
heatsinks) outputs 38 CFM. The noise is not noticeable with
some soft background music playing, which is a bonus. Whilst
some may prefer an all out massively powerful fan & not
care about the noise level, this fan is moreover for those
who get a bit sick of the constant whine from fan's on
heatsinks such as GlobalWin's FxP range. It’s not exactly
silent; its just not noisy. These fans aren't as hazardous
to touch (should you accidentally do so), you won't get any
fingers cut off. GlobalWin's FOP 38 on the other hand can
easily chop a nail off, and was often supplied with its own
grill.

 The
5E34B3 is almost identical to the aforementioned
5E32B3 apart from one important thing - the base is copper.
Whereas aluminium is a great emitter of heat, it is nowhere
near as good a conductor as copper is. So using a copper
base on an aluminium heatsink is therefore fairly logical -
the copper base easily draws heat away from the processor,
and the aluminium on the heatsink acts to disperse it. Or at
least that's the theory. So why don't all heatsinks have a
copper base? Well, firstly its a lot more expensive than
aluminium. Secondly, it’s denser than aluminium and adds
greatly to the weight of the heatsink. AMD has set strict
guidelines for the maximum weight of a socket A heatsink.
Just weighing the 5E34B3 and 5E32B3 by hand, its obvious
that the former is quite a bit heavier than the latter. The
copper base is worryingly only screwed into the rest of the
heatsink though & is easily removable. I would have
expected it to be epoxied or shrink fitted. The eagle eyed
among you may also notice the fan is capable of an extra 2
CFM, although as far as I could tell there was no difference
in the noise levels between this heatsink and the 5E32B3,
the official difference being just 0.1 dBA.
