1
00:00:00,800 --> 00:00:07,359
there's the 6870 of all of its d

2
00:00:04,080 --> 00:00:09,440
heatsinked glory so you can clearly see

3
00:00:07,359 --> 00:00:14,160
the GPU right here in the middle of the card surrounded by eight memory chips

4
00:00:12,559 --> 00:00:18,160
all right we've got not a whole lot of major heat producing

5
00:00:16,400 --> 00:00:21,760
components which should be quite obvious from the design of the heatsink because

6
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

7
00:00:23,680 --> 00:00:31,119
RAM here for some voltage regulation and then here for the GPU itself we've got

8
00:00:27,680 --> 00:00:33,200
three heat pipes on this copper hunk

9
00:00:31,119 --> 00:00:37,840
that looks actually just like a copper base and aluminum fins we've got some

10
00:00:36,320 --> 00:00:42,559
additional heat sinks right here above the vrm so you can see that's directly

11
00:00:40,160 --> 00:00:46,719
over top of where this thermal strip is making contact there you can see this

12
00:00:46,879 --> 00:00:52,800
thin heat pipe arrangement actually moves freely within the shroud so what

13
00:00:51,039 --> 00:00:56,719
that means is it's actually being bolted on separately by these four

14
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

15
00:00:59,440 --> 00:01:06,560
assembly where this is a large heatsink so this piece is metal and this piece is

16
00:01:04,080 --> 00:01:10,080
plastic so this is all one big heatsink is all

17
00:01:07,600 --> 00:01:15,200
attached separately so that's by the screws which are here

18
00:01:12,000 --> 00:01:16,799
here here here here

19
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

20
00:01:19,280 --> 00:01:26,479
back of this GPU only has about a quarter well half of one slot for

21
00:01:24,320 --> 00:01:31,680
exhaust so the way they've shaped the plastic shroud here is that the airflow

22
00:01:29,119 --> 00:01:34,400
goes from the fan here through

23
00:01:32,640 --> 00:01:38,799
all right so it comes through comes through these fins and then ultimately

24
00:01:36,720 --> 00:01:43,680
gets redirected by this wavy piece of plastic so that it all

25
00:01:40,720 --> 00:01:48,240
goes out the one side so there you are that's my in-depth look

26
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

27
00:01:50,399 --> 00:01:56,320
make sure i don't forget to put on when i reinstall this

28
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

29
00:01:58,399 --> 00:02:04,320
else to really tell you about it i'm not an electrical engineer so

30
00:02:02,640 --> 00:02:08,520
i can't really give you too many details about what everything is on here

31
00:02:10,080 --> 00:02:15,520
i can tell you this card's very water block unfriendly though just the

32
00:02:13,840 --> 00:02:18,480
positioning of these guys in here and how high these are means you're going to

33
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

34
00:02:20,319 --> 00:02:26,480
quite thick to get over those or i guess you could put

35
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

36
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

37
00:02:32,720 --> 00:02:38,800
see what guys like ek come up with because it'll probably be mostly them my

38
00:02:36,720 --> 00:02:43,200
heat killer who bother to come out with blocks for like a mid-range performance

39
00:02:40,959 --> 00:02:46,800
card typically we only see full cover blocks for the really high

40
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

41
00:02:49,440 --> 00:02:54,640
block though because you just throw a GPU block on here throw eight RAM sinks

42
00:02:53,040 --> 00:02:58,720
on and then basically find some way to cool this like chop up some heat sinks

43
00:02:56,560 --> 00:03:01,680
or something but like a nice beefy thing on there as long as you find something

44
00:03:00,080 --> 00:03:07,280
thin and tall it should be pretty good so there you have it naked Radeon

45
00:03:04,800 --> 00:03:11,920
