in our video review of the swifttech h220 we had a 20 Dee difference between
our Noctua n12 fans and the swifttech
Helix fans now we thought those results were pretty suspect at the time but we
reren them a few times um the problem
though is that we made a critical error we were using no to as low speeed
adapters on all of the fans and in the past it's never been an issue because
we've always just run KN to a fans but what we discovered is that while the
lowp speed adapters which we thought were just your standard sort of
undervolt from 12vt to 9vt sort of adapters we thought everything was hunky
dory um what we discovered is that while it'll tone these guys down from around
1400 RPM to around 1100 RPM it turns
swiftex Helix fans all the way down from 1,00 RPM to 600 RPM so the Helix fans to
get that 20° difference we're actually running at half of the RPM of the Noctua
fans Not only that but the swifttech 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 new vacuum filling
procedure that basically amounts to zero
air bubbles inside the system so we might have had air bubbles that were
getting caught in the pump causing the performance to degrade um 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 h220
and so that we can actually take it and retest it in a number of different
configurations so we're going to run our noctu a fans at 600 RPM to see how
comparable that is just you know let's see what happens if we both fans
we're going to run our Noctua fans at 1100 RPM which is our standard testing
procedure then we're going to run swiftex 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 going to run Swift text Unit at 1100 RPM then
we're going to take some additional fans we're going to grab some gentle typhoons
some GED Wings some air penetrator 121s we're going to 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 control ER 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 swifttech 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 swiftex fans
are not designed for voltage control but are designed for PW m control using a
four pin connector and a compatible pwm chipset so we're going to plug
everything into the CPU fan header and then we're going to plug both fans and
the pump into swiftex pwm splitter and
then report that result as well and on
that one we're going to 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
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
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 lowcost
Solutions due to just the overall design of the unit the better pump the better
uh see swifttech designed base PL
dramatically better design dramatically better performance than other lowcost
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
