H220 vs. H100i Same Fan Top Mount
The debates in the forums is pretty fierce when it comes to the All-In-One options, so testing with the kit fans alone is not quite satisfying. The question always arises, what if you put the same exact fans on each and run them at a couple of different speeds. So I did just that, I took the King of 1000-1800RPM fans, the mighty Scythe Gentle Typhoon AP-15 and ran it at approximately 1800RPM and again at 1300RPM to get a sense of both high speed and slower speeds. Past testing of radiators with various fin densities does show that radiators tend to be tuned for one area moreso than the other, so I hoped this would give you some indication of the radiator’s speed strengths as well. The kit fans being different makes that a bit difficult to tell.
Here are the two kit fans next to the mighty GT AP-15. I’ve searched long and hard for a fan that outperforms the GT, but have yet to find one besides other GTs of different speed flavors. It simply has a remarkable PQ curve with a very pronounced bump in the curve that makes it perform much better than what it’s box spec static pressure and max air flow would suggest. In the end, it spins around 1800RPM, moves air through a radiator like you would expect from typical 2200RPM fans, and sounds quieter than most 1500 RPM fans. It does have a unique sound tone (Absent of most air movement type noise) and not all like the way they sound, but from a raw CFM/dBA noise level perspective the GTs are generally untouched. Unfortunately they are not PWM enabled, so basic analog voltage control is your only speed control option. The H220 fans are similar in blade style and a good fan producing similar noise levels per RPM, however the GT PQ curve is very different and gives it that 2200RPM like performance. The H100i fan to the left has an amazing RPM range 600-2700 and certainly moves air and produces pressure well, but noise is where it suffers and begs for something more silent.
So…with that, it was time to mount up the mighty GT on the two kits and see how they compare with like fans. It’s a good fan upgrade for either kit if you’re able to control speeds as desired.
In the end, using the highly desirable and popular Gentle Typhoon AP-15, the H220 retains a lead over the H100i by about 2 degrees at full speed and 4 degrees at slower 1300 RPM speeds if full pump speeds are used. Lowering the H220 pump speeds a bit will lessen that slow speed gap by an estimated degree or two, but the H220 remains superior over the H100i using the same GT AP-15 fan.
