Performance:::...
We've
seen what the JACSH1 is and what it looks like, but all
this is for nothing if the performance stinks. With that
in mind it was time to see if there are any real-world advantages
over the stock cooler.
Firstly
I dug out our trusty Raytek
Minitemp and read the temperature from the rear of the
VPU while under load.

Impressive
is an understatement, in fact I repeated the measurement
twice, including replacing the old cooler, to make absolutely
certain that I was taking a reading from the same part of
the same scene while I was looping 3DMark, and that it had
performed the same number of complete loops before I took
the readng.
It's
no mistake, in my particular test system there was a mighty
13 degree improvement. I should state though that there's
no heating on where I did the testing so ambient was an
unusually low 10 degrees.
Just
to verify the results I performed the same procedure only
this time relying on the readings from the drivers' Overdrive
utlity. Here are the reported temperature:

To
save you the sums, that's 14 degrees cooler at idle and
25 degrees cooler under load when compared to the stock
cooler. However you look at it, those numbers are hard to
ignore and shows either how good the JACSH1 is, or how poor
the stock cooler is, or in fact more likely a bit of both.
The
fan was commendably quiet in operation despite the fact
that, unlike the stock fan, it's not thermally controlled
by the card and thus turns at full speed at all times. Being
of the ball bearing variety it should also be pretty durable
too. I was surprised by how much airflow it was able to
generate for such a quiet and small looking fan. I'm not
claiming it was silent by any means, but you'd not hear
it over a case fan.
Conclusion
The
3DVelocity 'Dual Conclusions Concept' Explained: After discussing
this concept with users as well as companies and vendors
we work with, 3DVelocity have decided that where necessary
we shall aim to introduce our 'Dual Conclusions Concept'
to sum up our thoughts and impressions on the hardware we
review. As the needs of the more experienced users and enthusiasts
have increased, it has become more difficult to factor in
all the aspects that such a user would find important, while
also being fair to products that may lack these high end
"bonus" capabilities but which still represent
a very good buy for the more traditional and more prevalent
mainstream user. The two catergories we've used are:
The
Mainstream User ~ The mainstream user is likely to put
price, stock performance, value for money, reliability and/or
warranty terms ahead of the need for hardware that operates
beyond its design specifications. The mainstream user may
be a PC novice or may be an experienced user, however their
needs are clearly very different to those of the enthusiast,
in that they want to buy products that operate efficiently
and reliably within their advertised parameters.
The
Enthusiast ~ The enthusiast cares about all the things
that the mainstream user cares about but is more likely
to accept a weakness in one or more of these things in exchange
for some measure of performance or functionality beyond
its design brief. For example, a high priced motherboard
may be tolerated in exchange for unusually high levels of
overclocking ability or alternatively an unusually large
heat sink with a very poor fixing mechanism may be considered
acceptable if it offers significantly superior cooling in
return.
The
Mainstream User ~
The
JACSH1 is a great cooler, and though you can probably make
do with the stock unit for the life of the card you own
provided you don't do any overclocking and have reasonable
case ventilation, there's no denying the old adage that
cool electronics are happy electronics.
It's
easy to fit and adds a touch of individuality to your PC,
the fact that it also cools better than any VGA cooler we've
tested to date is just a rather large, very juicy cherry
on top.
Its
only failing in my mind is that it ties up the adjacent
PCI slot, but I wouldn't let that colour your decision to
buy unless that slot is essential to you.
Hard
to fault.
The
Enthusiast ~
Not
too big, not too heavy, not too shabby! The JACSH1 has all
the credentials needed to become one very popular VGA cooling
alternative.
A
great base finish, the ability to work with shimmed GPUs/VPUs,
cool blue lighting and class-leading performance all supplement
the good looks and easy installation to make this an attractive
all-round cooling kit.
I've
fitted other VGA coolers to our X800 Pro in the past and
always removed them again when I'd finished testing. This
time I've left the H1 on the card and tucked the stock cooler
in a drawer.
Impressive!
We're
always looking for ways to make our reviews fairer. A Right
To Reply gives the manufacturer or supplier of the product
being reviewed a chance to make public comments on what
we've said. They can explain perhaps why they've done the
things we were unhappy with or blow their own trumpet over
the things we loved. It's easy for us to pick a product
apart but sometimes things are done a certain way for very
specific reasons.
Should
Jetart decide to exercise their "Right To Reply",
we'll publish their comments below:
