today I have kind of a special unboxing
from well I don't know I don't know who to tell you it's from because this is
more of a collaborative effort between two different companies I've actually
got two of them but I'll only be doing an overview of one so the first thing we
see when I open it up is a back plate so
this is an EVGA back plate says GeForce GTX 590 on it okay so we got some gaps
in the back for cooling the various components we've also got all the places
for screws to mount on it this is like a brushed aluminum look looks just
outstanding on the other side of it we've got thermal pads for all the
memory spots that need to be covered
which leads us to a piece of Styrofoam and then finally well not really finally
it didn't take that long the EVGA classified GeForce GTX 590
water block sorry about that so why
don't we have a look at the accessories that are included first we've got two
stubby 1/2 in fittings right there so these go into
the G1 qu threads you can arrange them any way you want whether you want them
both on this side both on the opposite side or you
can do one one way and one the other way whatever works best for the way your
tubing is routed next we've got a couple of Stoppers so you take those Stoppers
and you put them opposite where the fittings are so you go like
this so that it doesn't just go straight through the card and spray all over your
motherboard got some mounting hardware got a couple little uh lock washers got
some little screws there so you'll need that in order to mount the block finally
some thermal compound so the thermal compound will only in a case like this
be for the GPU locations themselves and
not for all of the memory and vrm and
other components that are on the PCB of the video card so let's have a look at
the construction of this product overall and so far I've only gotten to the EVGA
part of the collaboration but as soon as I remove this piece of plastic right
here it will become more apparent who
the other co- conspirator is in creating
this product see there powered by swifttech so that is machined into the
delin so this is a very very durable block for a couple of reasons many water
blocks over the past you know as long as people have been water cooling are
constructed from a copper base so here
you can see this is a copper base plated with nickel nickel is not harmful to
your water cooling Loop because it is close enough to Copper that you're not
going to have problems with corrosion okay so what that basically means is it
is safe to mix a loop with nickel blocks and copper blocks whereas it is not safe
to mix a loop with copper blocks and aluminum blocks so remember that you
guys okay also on the top instead of using a Plexi
top which is a clear top swifttech has
opted to go with a delin or atile top
which means that the odds of it cracking
are basically nothing with Plexi especially around the fittings like
around here sometimes if people crank the uh the barbs in too tight for
example you know just tighten that down really hard uh what can happen is you
can have little micro cracks form around it from the pressure delin is a very
very durable material and I would be floored if you could actually manage to
uh to damage a delin back or a delin
topped water block that way so I'm going to go ahead and I'm just going to take
off part of this because I don't want to make too much of a mess of these before
I'm ready to install them on the cards now normally you can only get a block
like this with an EVGA classified 590 card but because I already have
cards right here 590s I uh asked dvga to
send me just the blocks for this particular uh showcase so I'm going to
show you guys the uh the mirror shot check that out I mean look look how
reflective this thing is very very beautiful surface machined on there so
how does the technology actually work here well Swift Tech's been making
blocks for pretty much as long as anyone's been making commercial grade
blocks so the design is very simple but
very effective so now with a single GPU
card the design of a full cover block is
fairly simple it needs to get a little bit of of water flow over the vrm
components which are generally at the back of the card it's a little bit you know not not a huge deal you go away
thank you um so a little bit of cooling there because those components do get
hot under air cooling but under water cooling it's a it's a breeze it's no big
deal and then they need to Route the water around to the center of the card
and then out the out the outlet so in the inlet around to the center of the
card where the GPU is located and then out the outlet now with a dual GPU card
it's a little bit more complicated so the water path in this particular block
goes in one and it doesn't really matter which in one goes through a pin Matrix a
very tight pin Matrix here which is around one of the
gpus okay which actually has a like a
Blocker on the delin top in order to accelerate the water as it flows around
the GPU itself then it widens out again
okay so it flows quite easily here and then it goes under another another tight
um a tight covering from the top through another pin Matrix and then out the
outlet so why does swifttech do this the reason is that cooling performance is
dramatically better when you restrict the flow of the water so it flows faster
over the parts that need to be cooled the most so why don't they do it
throughout the entire block well that's a smart design design decision as well
what that would mean if they had the entire block restrictive and impinging
and jetting the water onto the uh
surface of the water block to cool the card would make this block very
restrictive so it would mean in order to run a couple of these blocks with dual
590s in a loop you would need like a couple pumps in order to just get the
water through there at a reasonable
velocity uh last but not least we've also got a glowing EVGA logo up here at
the top so that's going to look pretty good when it's installed in my Ultimate
machine which I will be building over the next little while and that is lit up
using the fan header on the PCB itself
so we got a little cord there I don't know if I mentioned this already but on
the back you can see all of the RAM cooling spots as well as uh thermal pads
to cover the vrm portion of the cooling on the back so thank you for checking
out my unboxing and overview of the EVGA classified GTX 590 block don't forget to
get one of these you will have to buy an EVGA gForce GTX 590 classified water
cooled Edition card thank you for checking it out don't forget to subscribe to lineus techtips from
