00:00:02,720 --> 00:00:12,639
in our video review of the swifttech h220 we had a 20 Dee difference between

2
00:00:08,840 --> 00:00:15,599
our Noctua n12 fans and the swifttech

3
00:00:12,639 --> 00:00:20,840
Helix fans now we thought those results were pretty suspect at the time but we

4
00:00:17,320 --> 00:00:22,960
reren them a few times um the problem

5
00:00:20,840 --> 00:00:27,080
though is that we made a critical error we were using no to as low speeed

6
00:00:24,960 --> 00:00:30,840
adapters on all of the fans and in the past it's never been an issue because

7
00:00:28,640 --> 00:00:34,040
we've always just run KN to a fans but what we discovered is that while the

8
00:00:32,559 --> 00:00:38,239
lowp speed adapters which we thought were just your standard sort of

9
00:00:35,960 --> 00:00:43,079
undervolt from 12vt to 9vt sort of adapters we thought everything was hunky

10
00:00:40,239 --> 00:00:48,320
dory um what we discovered is that while it'll tone these guys down from around

11
00:00:45,079 --> 00:00:50,440
1400 RPM to around 1100 RPM it turns

12
00:00:48,320 --> 00:00:57,160
swiftex Helix fans all the way down from 1,00 RPM to 600 RPM so the Helix fans to

13
00:00:54,879 --> 00:01:02,640
get that 20° difference we're actually running at half of the RPM of the Noctua

14
00:01:00,480 --> 00:01:07,360
fans Not only that but the swifttech fans were only run with the pump at full

15
00:01:04,879 --> 00:01:12,640
speed and what we found out is that our units here may actually be not quite

16
00:01:10,840 --> 00:01:18,000
optimal in terms of their performance because these are early samples that are

17
00:01:14,840 --> 00:01:21,079
not using Swift Tech new vacuum filling

18
00:01:18,000 --> 00:01:23,200
procedure that basically amounts to zero

19
00:01:21,079 --> 00:01:26,240
air bubbles inside the system so we might have had air bubbles that were

20
00:01:24,759 --> 00:01:30,240
getting caught in the pump causing the performance to degrade um with the pump

21
00:01:28,840 --> 00:01:34,200
running at full speed which might be part of why we got our best results when

22
00:01:32,079 --> 00:01:41,320
running the pump at half speed so we're waiting for a retail unit of the h220

23
00:01:38,560 --> 00:01:45,920
and so that we can actually take it and retest it in a number of different

24
00:01:43,439 --> 00:01:51,079
configurations so we're going to run our noctu a fans at 600 RPM to see how

25
00:01:49,600 --> 00:01:55,119
comparable that is just you know let's see what happens if we both fans

26
00:01:53,320 --> 00:01:58,640
we're going to run our Noctua fans at 1100 RPM which is our standard testing

27
00:01:57,240 --> 00:02:04,520
procedure then we're going to run swiftex fans at 600 RPM again with the

28
00:02:02,159 --> 00:02:07,399
new fixed unit all with the pump at half because that doesn't seem to affect

29
00:02:05,719 --> 00:02:12,360
performance much and then we're going to run Swift text Unit at 1100 RPM then

30
00:02:10,759 --> 00:02:16,920
we're going to take some additional fans we're going to grab some gentle typhoons

31
00:02:14,239 --> 00:02:21,400
some GED Wings some air penetrator 121s we're going to run all of those at 1100

32
00:02:18,760 --> 00:02:25,080
RPM this is all in a pull configuration because that's the configuration that I

33
00:02:22,760 --> 00:02:28,560
prefer to use we've added something to our test bench here that we didn't have

34
00:02:26,840 --> 00:02:33,400
before so check it out we have a variable fan speed control ER in the

35
00:02:30,360 --> 00:02:35,280
front so we can use software to exactly

36
00:02:33,400 --> 00:02:40,480
monitor the RPMs of the fans and fine-tune them to make sure that noise

37
00:02:37,360 --> 00:02:42,440
levels and RPM levels are the same and

38
00:02:40,480 --> 00:02:47,440
then last but not least swifttech has also asked us to test theirs in a push

39
00:02:45,680 --> 00:02:53,360
configuration which is the way it ships stock and to also try using pwm control

40
00:02:51,400 --> 00:02:58,440
for the whole unit itself because part of the problem may be that swiftex fans

41
00:02:56,120 --> 00:03:03,799
are not designed for voltage control but are designed for PW m control using a

42
00:03:01,239 --> 00:03:08,080
four pin connector and a compatible pwm chipset so we're going to plug

43
00:03:05,280 --> 00:03:13,640
everything into the CPU fan header and then we're going to plug both fans and

44
00:03:10,519 --> 00:03:17,040
the pump into swiftex pwm splitter and

45
00:03:13,640 --> 00:03:19,319
then report that result as well and on

46
00:03:17,040 --> 00:03:24,159
that one we're going to Target 1100 RPM for the fans so this should give us the

47
00:03:21,319 --> 00:03:28,200
most complete and clear picture of how the Swift Tech cooler performs now I

48
00:03:26,920 --> 00:03:33,360
it's going to take us a little while to get this done so that's why I'm releasing this video so you guys know

49
00:03:31,080 --> 00:03:37,959
that it's coming but in the meantime remember guys our result with it

50
00:03:35,879 --> 00:03:43,280
performing better than everything else is still valid because this engineering

51
00:03:41,000 --> 00:03:47,400
sample unit had everything going against it and with the Noctua cooler compared

52
00:03:45,959 --> 00:03:50,959
to every other liquid cooler that we've tested due to its copper radiator

53
00:03:49,519 --> 00:03:55,439
compared to the aluminum finned radiators that are used in other lowcost

54
00:03:52,840 --> 00:04:00,799
Solutions due to just the overall design of the unit the better pump the better

55
00:03:57,640 --> 00:04:02,840
uh see swifttech designed base PL

56
00:04:00,799 --> 00:04:06,519
dramatically better design dramatically better performance than other lowcost

57
00:04:04,400 --> 00:04:10,079
coolers it is the best performing cooler on the market if you add aftermarket

58
00:04:08,560 --> 00:04:13,879
fans we just need to do more investigation into the stock ones that

59
00:04:12,000 --> 00:04:18,639
