I'm trying to figure out where I'm wrong here so if someone sees something blatantly obvious that I'm missing, don't hesitate to point it out.

My Awesome 8Q is running 2 PPCs and 1 ER PPC with 19 double heat sinks and a 300 standard engine. My heat dissipation should be (10*2)+(9*1.4)=32.6 per second adjusted to 37.49 per second with 2x Cool Run. Two PPCs and one ER PPC generate a total of 31 heat per second or a 33.5 heat per second with Fast Fire. So, even with ambient heat on, say, normal Forrest Colony, I should be able to out cool the heat I generate. But this isn't the case so what am I not looking at?

Your math is wrong.

A PPC generates (10/3.0)*8 = 27 heat per 10 seconds
An ER PPC generates (10/3)*11 = 37 heat per 10 seconds


So two PPCs and an ER PPC generates 91 heat per 10 seconds and you only dissipate 38 heat per 10 seconds

[Vlad Ward]

Your math is off. The old TT rules for heat sinks were based on 10 second rounds, so you're not dissipating 37.5 heat every second but 37.5 heat every 10 seconds.

Edit, likewise, those are heat per shot values and not heat per second values for the PPCs.

Damn, that's right. Was thinking that everything was based on a per second basis. Derp, thanks Khobai.

too slow. Oh well you have to fire them once every ten seconds to get close to a heat neutral build (possible in tabletop with the strict once-per-ten-seconds firing) but obviously in MWO you are capable of firing much more often.

Ur not the first and u wont be the last to think a heat sink is dissapating 1 heat per second instead of 1 heat every 10 seconds

[Joe Mallad]

Yes so people need to be reminded that a standard HS dissipates 0.1 heat a second

A 1.4 DHS dissipates 0.14 heat a second.

And a true 2.0 DHS dissipates 0.2 heat a second.

So the OPs current build at 10x2.0 DHS and 9x1.4 DHS will allow him to dissipate 3.26 heat a second.

I run an aws-8q with 2x ppc's, LL, 4x ML. I have 20 dhs, and an std 290. Even without the math I can do alot of firing before shutting down. Keep in mind that dhs raises your overall shutdown threshold, even if heat dissipation numbers arn't much better that standard heat sinks.

[BlackBeltJones]

Let me first offer that I may be a moron regarding this BUT does the standard 300 engine have 12 internal HS which would mean the OPs mech has 7 additional external HS thus (12*2) + (7*1.4) /10 = 3.38 heat dissipation per second?

[Diablobo]

Yes, the math is off. Congratulations, you have discovered why triple-heat Battletech really sucks. We have tripled firing rates with only single rate capable heat sinks. Instead of Mechwarrior Online we have EZbake Oven Online.

The 300 has 12 slots. Only 10 of them come standard with the engine and function at the 0.2 rate. The other two come in the form of "Heat Sink Slots" which can be added to the Engine itself at no Critical cost, and count at the 0.14 rate.

It's such a simple system, I don't get why people have so much trouble with it...


Oh, wait, it isn't, and I completely understand.

[Biglead]

(Math/0.math) =math.mathflashlight, but you have to account that Bubblegum divided by Keychain= Egypt...which you did not.

Your math is stating that Cellphone(bouncy ball/A puppy+hieroglyphics)= Alphastrike laughter. No wonder you spent 80% of the match shut down.









I wish I was good at math.

Not to mention the fact that it is perfectly documented in the mechlab, the tutorial, and the user's manual... What? You don't have those yet? Huh

It works fine for me.

At least it can be found in the forums in the General FAQ.

By which I mean - questions on how double heat sinks and heat works are frequently asked.
