Developer: Cooler Master
Release Date: Out Now
Cooler Master, one of the
world’s leaders in PC cooling technology, have cooked up
something completely different with the new Jet4. The
radical new “Jet” fan looks very impressive and stylish,
whether it cools as well as it looks is yet to be revealed.
|
Cooler Master produce a huge
selection of cooling orientated equipment. Whether it’s a
computer case, thermal probe, or just a fan for your CPU,
Cooler Master has products to suit the hardcore user, or the
skint student. They originally produced the jet fan for
Intel’s rival AMD, and it was a little while until the Jet 4
P4 cooler came along and frankly the thing is a beast. The
Jet 4 is huge, much bigger than I originally expected at
130mm tall and weighing 700g! |

The fan comes well packaged showing off the stylish Jet
engine, and for once I did not have to battle to get the
box open with industrial size shears. The fan comes
packaged with a choice of to speed control fittings, one
for your 3.5” FDD bay, or a bracket that goes in the
back of your computer next to your PCI and AGP slots. I
personally went for the front option for easy of use,
and extra style. Also packaged with the cooler you got
some silicon thermal compound and clear installation
instructions.
Installation was easy to understand, yet a little tricky
to do. The computer needed to be on its side because the
attachment brackets aren’t attached to the cooler which
make the job of mounting the cooler a little fiddly.
This is partly due to the shear size of the jet.
The weight of the cooler was obviously due to the new
design copper heatsink. It is split up into lots of thin
copper plates with a large copper slab on the underneath
where it has contact with the CPU. The large number of
copper strips increases surface area and therefore there
is an increased airflow over the heatsink which vastly
improves cooling.

The
whole idea behind the Jet engine itself is that it is
meant to give much better cooling at lower speeds. This
is because with conventional fans, you get a blind spot
in the middle where there are no spinning blades. On a
CPU fan/heatsink this centre blind spot is directly over
the CPU itself. However the new jet fan doesn’t have a
blind spot giving equal airflow over the entirety of the
heatsink.
Well that’s the theory! The question is now, does it
perform as well as it is meant to? I can happily say yes
to that question, there is a substantial drop in CPU
temperature with the Jet 4. My system temperature is
never particularly cool due to the amount of hardware in
there, so test conditions for my results will not have
brought the best out of this cooler. However it’s the
comparison between the factory cooler and the Jet 4
which matters. And in the graph it can be seen that
under load with the factory cooler the temperature gets
as high as 55, whereas with the Jet 4 it sits at about
46 (47 at min RPM). Combined with the idle temperatures
of 50 and 42 (43 at min RPM) it’s obvious that Cooler
Master have hit the nail on the head and created a
superior cooling machine.

Quality: |
10/10
|
| |
Excellent quality as
would be expected from a world renowned company such
as Cooler Master. |
| |
|
|
Price: |
9/10
|
| |
Not the cheapest
cooler around, but not the most expensive, and for
the cooling power, £35 is worth it. |
| |
|
|
Installation: |
8/10
|
| |
A little bit fiddly,
and maybe a little tricky for less competent users
but its not rocket science. It fits and installs
fairly easily. |

Compatibility: |
9/10 |

Will cooler any P4
that is out today, but you do need a little room in
you tower, but it just sticks out in front of your
CPU, so unless you have a very short motherboard
power cable you shouldn’t have any problems here |

Performance : |
9/10
|
| |
It isn’t a water
cooler, but it performs well, and substantially
better than the stock fan! |

Overall
: 45/50
Great
cooling, with unique style Cooler Master
have created a top notch fan. And how cool
is a Jet in your computer! |
