Just Cooler P-5500
Maybe P-5500 is the model
number for this cooler. I've only seen it sold as the P-5500, but it might
be meant to be called the "RD-100C". That's what it's called on this
masterful page on the Taiwanese Just Cooler Site. Except for
the blue anodising, it also looks just like the Spring
Spread SBCT601CAF-1B, two not-very-informative PDF documents
about which can be downloaded here
and here.
Whatever its name is, it certainly
looks the part, doesn't it?
It's a weighty little cooler,
because inside its blue-anodised extruded aluminium shell, there's a copper
pylon and a plethora of super-thin copper fins.
The pylon sticks out of the
bottom of the shell, giving the CPU a copper circle for, Just Cooler no
doubt hope, better thermal transfer. Air's fed through the cooler by a low
profile high speed 50mm fan at one end, which isn't particularly loud, but
has the distinctive high whine of a fast fan nonetheless.
Unfortunately,
the P-5500 (or whatever) is all show and no go. It turned in a thoroughlyunexciting 0.73°C/W when I first tested it on the
cut-up socket.
When I tried to install it
on the steel socket setup, the clip broke.
Given the average difference
in performance between the two setups - the steel socket gave consistently
higher thermal resistance readings than the too-tight socket had - I reckon
it probably would have achieved around 0.8°C/W, if it hadn't broken.
That's not absolute garbage,
but it's far from the performance you'd expect from a funkalicious-looking
copper-finned exotic like this.
Even if it were a brilliantly
efficient cooler, you wouldn't want this thing. That clip broke because
it's tight enough to win the my Giant Nasty Mallet Smashing Your CPU To
Little Bits Award for this month. It's got very little give in it, and was
rather challenging to attach. I needed to use a G-clamp to compress it enough
that I could remove it from the slotket again.
This thing can and will destroy
CPUs, especially Socket A ones; using a shim may help, but I wouldn't bet
on it.
The retail price for this cooler
is apparently about $USD39, on par for other zooty copper coolers, although
this
store appears to be aware of the quality of the product and has
'em reduced to $USD19.95.
