00:00:00.800 --> 00:00:07.359
there's the 6870 of all of its d

00:00:04.080 --> 00:00:09.440
heatsinked glory so you can clearly see

00:00:07.359 --> 00:00:14.160
the GPU right here in the middle of the card surrounded by eight memory chips

00:00:12.559 --> 00:00:18.160
all right we've got not a whole lot of major heat producing

00:00:16.400 --> 00:00:21.760
components which should be quite obvious from the design of the heatsink because

00:00:20.160 --> 00:00:26.000
you can see it only makes contact with the card here for the RAM here for the

00:00:23.680 --> 00:00:31.119
RAM here for some voltage regulation and then here for the GPU itself we've got

00:00:27.680 --> 00:00:33.200
three heat pipes on this copper hunk

00:00:31.119 --> 00:00:37.840
that looks actually just like a copper base and aluminum fins we've got some

00:00:36.320 --> 00:00:42.559
additional heat sinks right here above the vrm so you can see that's directly

00:00:40.160 --> 00:00:46.719
over top of where this thermal strip is making contact there you can see this

00:00:46.879 --> 00:00:52.800
thin heat pipe arrangement actually moves freely within the shroud so what

00:00:51.039 --> 00:00:56.719
that means is it's actually being bolted on separately by these four

00:00:54.800 --> 00:01:01.840
see you can see those ones will actually move that piece and then the rest of the

00:00:59.440 --> 00:01:06.560
assembly where this is a large heatsink so this piece is metal and this piece is

00:01:04.080 --> 00:01:10.080
plastic so this is all one big heatsink is all

00:01:07.600 --> 00:01:15.200
attached separately so that's by the screws which are here

00:01:12.000 --> 00:01:16.799
here here here here

00:01:15.200 --> 00:01:21.600
this is kind of neat the way they've done the shroud here as you know the

00:01:19.280 --> 00:01:26.479
back of this GPU only has about a quarter well half of one slot for

00:01:24.320 --> 00:01:31.680
exhaust so the way they've shaped the plastic shroud here is that the airflow

00:01:29.119 --> 00:01:34.400
goes from the fan here through

00:01:32.640 --> 00:01:38.799
all right so it comes through comes through these fins and then ultimately

00:01:36.720 --> 00:01:43.680
gets redirected by this wavy piece of plastic so that it all

00:01:40.720 --> 00:01:48.240
goes out the one side so there you are that's my in-depth look

00:01:45.759 --> 00:01:52.479
at the cooler of the 5870 there's the 4-pin pwm fan connector that i better

00:01:50.399 --> 00:01:56.320
make sure i don't forget to put on when i reinstall this

00:01:55.119 --> 00:01:59.759
maybe we can look a little bit more closely at the card i'm not sure what

00:01:58.399 --> 00:02:04.320
else to really tell you about it i'm not an electrical engineer so

00:02:02.640 --> 00:02:08.520
i can't really give you too many details about what everything is on here

00:02:10.080 --> 00:02:15.520
i can tell you this card's very water block unfriendly though just the

00:02:13.840 --> 00:02:18.480
positioning of these guys in here and how high these are means you're going to

00:02:16.959 --> 00:02:22.319
have to waste a lot of copper to make a block for this because it have to be

00:02:20.319 --> 00:02:26.480
quite thick to get over those or i guess you could put

00:02:23.599 --> 00:02:31.280
such a thin strip though like you could you could put a gap so that the whole

00:02:28.720 --> 00:02:34.720
thing sits over top of that but yeah i don't know i'll be interested to

00:02:32.720 --> 00:02:38.800
see what guys like ek come up with because it'll probably be mostly them my

00:02:36.720 --> 00:02:43.200
heat killer who bother to come out with blocks for like a mid-range performance

00:02:40.959 --> 00:02:46.800
card typically we only see full cover blocks for the really high

00:02:44.720 --> 00:02:50.640
end cards it'd be really easy to uh to water cool this card with a GPU

00:02:49.440 --> 00:02:54.640
block though because you just throw a GPU block on here throw eight RAM sinks

00:02:53.040 --> 00:02:58.720
on and then basically find some way to cool this like chop up some heat sinks

00:02:56.560 --> 00:03:01.680
or something but like a nice beefy thing on there as long as you find something

00:03:00.080 --> 00:03:07.280
thin and tall it should be pretty good so there you have it naked Radeon

00:03:04.800 --> 00:03:11.920
