in our video review of the swift tech age to 20 we had a 20 degree difference between our noctua and ff12 fans and the swift tech helix fans now we thought those results were pretty suspect at the time but we rerun them a few times the problem though is that we made a critical error we were using naktu as low-speed adapters on all of the fans and in the past it's never been an issue because we've always just run knocked to a fence but what we discovered is that while the low-speed adapters which we thought were just your standard sort of under volt from 12 volt to nine volt sort of adapters we thought everything was hunky-dory what we discovered is that while it'll tone these guys down from around 1,400 rpm to around 1,100 rpm it turned swift Tex helix fans all the way down from 1800 rpm to 600 rpm so the helix fans to get that 20 degree difference we're actually running at half of the RPM of the Noctua fans not only that but the Swift tech fans were only run with the pump at full speed and what we found out is that our units here may actually be not quite optimal in terms of their performance because these are early samples that are not using Swift Tech's new vacuum filling procedure that basically amounts to zero air bubbles inside the system so we might have had air bubbles that we're getting caught in the pump causing the performance to degrade with the pump running at full speed which might be part of why we got our best results when running the pump at half speed so we're waiting for a retail unit of the h2 20 and so that we can actually take it and retest it in a number of different configurations so we're gonna run our noctua fans at 600 rpm to see how comparable that is just you know let's see what happens if we cripple both fans we're gonna run our knock - offends at 1100 rpm which is our standard testing procedure then we're gonna run Swift Tex fans at 600 rpm again with the new fixed unit all with the pump at half because that doesn't seem to affect performance much and then we're gonna run Swift text unit at 1100 rpm then we're gonna take some additional fans we're going to some gentle typhoons some gelid wings some air penetrator 121 we're gonna run all of those at 1100 rpm this is all in a pull configuration because that's the configuration that I prefer to use we've added something to our test bench here that we didn't have before so check it out we have a variable fan speed controller in the front so we can use software to exactly monitor the RPMs of the fans and fine-tune them to make sure that noise levels and rpm levels are the same and then last but not least Swift Tech has also asked us to test theirs in a push configuration which is the way it ships stock and to also try using PWM control for the whole unit itself because part of the problem may be that Swift Tech's fans are not designed for voltage control but are designed for PWM control using a four pin connector and a compatible PWM chipset so we're gonna plug everything into the CPU fan header and then we're gonna plug both fans and the pump into Swift X PWM splitter and then report that result as well and on that one we're gonna target 1100 rpm for the fans so this should give us the most complete and clear picture of how the Swift tech cooler performs now I'm just gonna take a little while to get this done so that's why I'm releasing this video so you guys know that it's coming but in the meantime remember guys our result with it performing better than everything else is still valid because this engineering sample unit had everything going against it and with the Noctua cooler compared to every other liquid cooler that we've tested due to its copper radiator compared to the aluminum finned radiators that are used in other low-cost solutions due to just the overall design of the unit the better pump the better see swift tech designed base plate dramatically better design dramatically better performance than other low-cost coolers it is the best performing cooler on the market if you add aftermarket fans we just need to do more investigation into the stock ones that are included thanks for watching this video sort of a blog style video and as always don't forget to subscribe to Alanis tech tips for more unboxings reviews and other computer videos
