MechWarrior Online Heat Ratio Guide
MechWarrior Online Heat Ratio Guide by ZodiacX
As the title suggests, this guide is intended to go over the concept of heat ratios and how to use that knowledge when building your mech. It should be noted that this guide assumes nominal heat sink dissipation, and disregards the environmental effects of caustic valley and frozen city.
The “Standard” Heat Ratio:
This heat ratio calculates a linear ratio of heat generation vs dissipation and is calculated by the following formula:
[Heat per Second] is the summation of the of the Heat per Second value of all weapons you are firing in a group. In general, you should use your alpha-strike value (the total from all equipped weapons). [Heat Sinks] is the number of equipped heat sinks, nice and simple. The reason that this formula has a factor of 10 is because a standard heat sink dissipates 0.1 heat per second, so it takes 10 seconds for 1 heatsink to dissipate 1 heat.
Interpretting the “Standard” Alpha-Strike Heat Ratio:
[Heat Ratio] <= 1.0
1.0 < [Heat Ratio] < 1.5
1.5 < [Heat Ratio] < 2.0
2.0 < [Heat Ratio] < 2.5
2.5 <= [Heat Ratio]
The MWO Mechlab Heat Ratio:
This heat ratio is non-linear and therefore is a little harder to interpret. The formula has been calculated be approximately:
Note that the ratio of [Heat Sinks] to [Heat per Second] is flipped relative to how the “Standard” Heat Ratio uses them. This is important as it signifies a reverse trend in the MWO mechlab. Below is a table which provides a correlation between the “Standard” and MWO Heat Ratios.
Other Heat Notes:
You will run hotter on caustic.
You will run cooler on frozen valley.
Double heat sinks theoretically are twice as efficient as single heat sinks.
Any heat sinks in your legs will be twice as efficient when standing in water.
