Using the data compiled from the Coolgate G2 thermal testing I have compiled the following tables in an attempt to show another way how the G2 performance varies against itself at the flow rates and fan speeds tested. First let’s start with the raw numbers:
Now let’s use these to show percentage gains relative to a reference point. It’s an interesting way to show gains/losses while changing a variable. This first table shows performance gain or loss relative to 1.0GPM flow rate:
We can also focus on 1300RPM as our reference and see how much gain or loss in performance we get by changing fan speed:
So from the data above we can get a very good idea of how the G2 radiator performs relative to itself. But there is a large selection of 360mm radiator models to choose from, released from numerous manufacturers. So, we need to start comparing performance between them. To see how the radiator performed against the other radiators in this group I have included the averaged flow rate comparison charts from the Round Up. We know that the flow rate has little impact on thermal performance so averaging of the 3 flow rate results gives us a good look at head to head performance at the rpm speeds tested at with even less error.
Let’s start off with the Push only results:
The G2 does poorly at 750RPM. The thick radiator presumably needs some pressure to really get going. Although there are worse performers, those performers are all tuned with high FPI.
At 1300 RPM the G2 starts climbing up. However it’s still below average.
By 1850RPM the G2 is clearly in the top half of the performers, but it is still not standing out. Let’s see if Push/Pull helps it do better:
This time at 750RPM the G2 is already off to a better start.
Now at 1300 RPM it looks like more convincing finishing in 6th place now.
At 1850RPM it moves up to 5th place. A good finish, but it can’t compete with higher FPI designs that are tweaked with high airflow in mind.
At 1GPM we can compare apples to apples with regard to Push vs Push/Pull. This makes for some interesting comparisons, but the plots do get quite busy:
As we know 750RPM is not the G2’s strong point.
At 1300RPM the G2 with Push starts over taking the worst of the Push/Pull radiators.
At 1850RPM the G2 with Push/Pull is still significantly above the best Push only radiator, meanwhile the G2 with Push has over taken a good number of Push/Pull setups.
From all of these results we can create a “master performance factor”. The radiator with the best cooling ability (W/10ΔT) at each gpm/rpm combo was awarded a score of 100, and each other radiators W/10ΔT result was scored as percentage of the top performer:
Then all the percentage scores were averaged giving us the Averaged Performance Factor of each radiator. This way of looking at the comparison takes away any advantages that a radiator may have at higher or lower fan speeds and looks at an overall average. While this appears fair it does tend to favor those radiators that are all rounders and those radiators which do very well at high RPM. Most users should be more focused on their specific use case. Check in the Round Up for performance comparisons at every gpm/rpm combo for even more details and cross comparison results.
First up – the overall Push performance:
Here the G2 performs solidly in the middle of the pack.
