Manufacturer Website: Speeze
The Speeze product code
Each letter or number on any Speeze
cooler product uniquely identifies the product & gives
information such as the fan type, socket type, fan connector
etc.

I don't quite know how the 5P53B3 fits
into this, apparently there is no fan type "P".
Speeze also offers a service whereby if a cooler for your
system isn't available, it can be requested to order. This
is something I have never come across before. There was no
indication about the potential costs of this service.
Noise levels
The fan on the copper 5P53B3 has a very
high pitch whine to it. This isn't as bad as it would seem
however; as it is still fairly quiet. It is not audible with
some soft music playing in the background. Although the
5E34B3 is officially louder than the 5E32B3 or the
aforementioned 5P53B3, I couldn't perceive it as being
louder. None of the fans are the quietest around, and do not
mach up to the low noise levels on some Taisol fans;
nevertheless they are perfectly acceptable for background
noise.
To test the CPU under load I ran a
couple of loops in 3D Mark. Idle temperatures were tested
after leaving the PC on for an hour. I used the thermal
compound rather than the pink thermal pad for all three
heatsinks.

Surprisingly,
all the processors exhibited similar idle temperatures. I'll
put this down to the underpowered fans they were all fitted
with.
