WEBVTT 00:00:02.720 --> 00:00:12.639 in our video review of the swifttech h220 we had a 20 Dee difference between 00:00:08.840 --> 00:00:15.599 our Noctua n12 fans and the swifttech 00:00:12.639 --> 00:00:20.840 Helix fans now we thought those results were pretty suspect at the time but we 00:00:17.320 --> 00:00:22.960 reren them a few times um the problem 00:00:20.840 --> 00:00:27.080 though is that we made a critical error we were using no to as low speeed 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 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 00:00:32.559 --> 00:00:38.239 lowp speed adapters which we thought were just your standard sort of 00:00:35.960 --> 00:00:43.079 undervolt from 12vt to 9vt sort of adapters we thought everything was hunky 00:00:40.239 --> 00:00:48.320 dory um what we discovered is that while it'll tone these guys down from around 00:00:45.079 --> 00:00:50.440 1400 RPM to around 1100 RPM it turns 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 00:00:54.879 --> 00:01:02.640 get that 20° difference we're actually running at half of the RPM of the Noctua 00:01:00.480 --> 00:01:07.360 fans Not only that but the swifttech fans were only run with the pump at full 00:01:04.879 --> 00:01:12.640 speed and what we found out is that our units here may actually be not quite 00:01:10.840 --> 00:01:18.000 optimal in terms of their performance because these are early samples that are 00:01:14.840 --> 00:01:21.079 not using Swift Tech new vacuum filling 00:01:18.000 --> 00:01:23.200 procedure that basically amounts to zero 00:01:21.079 --> 00:01:26.240 air bubbles inside the system so we might have had air bubbles that were 00:01:24.759 --> 00:01:30.240 getting caught in the pump causing the performance to degrade um with the pump 00:01:28.840 --> 00:01:34.200 running at full speed which might be part of why we got our best results when 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 00:01:38.560 --> 00:01:45.920 and so that we can actually take it and retest it in a number of different 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 00:01:49.600 --> 00:01:55.119 comparable that is just you know let's see what happens if we both fans 00:01:53.320 --> 00:01:58.640 we're going to run our Noctua fans at 1100 RPM which is our standard testing 00:01:57.240 --> 00:02:04.520 procedure then we're going to run swiftex fans at 600 RPM again with the 00:02:02.159 --> 00:02:07.399 new fixed unit all with the pump at half because that doesn't seem to affect 00:02:05.719 --> 00:02:12.360 performance much and then we're going to run Swift text Unit at 1100 RPM then 00:02:10.759 --> 00:02:16.920 we're going to take some additional fans we're going to grab some gentle typhoons 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 00:02:18.760 --> 00:02:25.080 RPM this is all in a pull configuration because that's the configuration that I 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 00:02:26.840 --> 00:02:33.400 before so check it out we have a variable fan speed control ER in the 00:02:30.360 --> 00:02:35.280 front so we can use software to exactly 00:02:33.400 --> 00:02:40.480 monitor the RPMs of the fans and fine-tune them to make sure that noise 00:02:37.360 --> 00:02:42.440 levels and RPM levels are the same and 00:02:40.480 --> 00:02:47.440 then last but not least swifttech has also asked us to test theirs in a push 00:02:45.680 --> 00:02:53.360 configuration which is the way it ships stock and to also try using pwm control 00:02:51.400 --> 00:02:58.440 for the whole unit itself because part of the problem may be that swiftex fans 00:02:56.120 --> 00:03:03.799 are not designed for voltage control but are designed for PW m control using a 00:03:01.239 --> 00:03:08.080 four pin connector and a compatible pwm chipset so we're going to plug 00:03:05.280 --> 00:03:13.640 everything into the CPU fan header and then we're going to plug both fans and 00:03:10.519 --> 00:03:17.040 the pump into swiftex pwm splitter and 00:03:13.640 --> 00:03:19.319 then report that result as well and on 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 00:03:21.319 --> 00:03:28.200 most complete and clear picture of how the Swift Tech cooler performs now I 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 00:03:31.080 --> 00:03:37.959 that it's coming but in the meantime remember guys our result with it 00:03:35.879 --> 00:03:43.280 performing better than everything else is still valid because this engineering 00:03:41.000 --> 00:03:47.400 sample unit had everything going against it and with the Noctua cooler compared 00:03:45.959 --> 00:03:50.959 to every other liquid cooler that we've tested due to its copper radiator 00:03:49.519 --> 00:03:55.439 compared to the aluminum finned radiators that are used in other lowcost 00:03:52.840 --> 00:04:00.799 Solutions due to just the overall design of the unit the better pump the better 00:03:57.640 --> 00:04:02.840 uh see swifttech designed base PL 00:04:00.799 --> 00:04:06.519 dramatically better design dramatically better performance than other lowcost 00:04:04.400 --> 00:04:10.079 coolers it is the best performing cooler on the market if you add aftermarket 00:04:08.560 --> 00:04:13.879 fans we just need to do more investigation into the stock ones that 00:04:12.000 --> 00:04:18.639 are included thanks for watching this video sort of a Blog Style video
