I've always found this strange, but what's the logic in increasing a mech's heat capacity? Heat capacity is determined by the people who designed and engineered the components of the mech, cooling has no effect on the failure point of components. All heat dissipating devices, such as heat sinks, can do, is work hard to cool components fast enough to prevent them from reaching that failure point in the first place.

Example: The video cards in the computers of most gamers are fairly high end, heat generating monsters. You'll notice that on most of these cards there's a fan and metal fins attached, the metal fins of course are called heat sinks, indicating their prime purpose in the design. The harder load you put on your video card, the more heat it generates, and the more you hear the fan whirring. If the fan fails, or if the ambient operating temperature inside the computer case is too hot, because you're playing in Phoenix in July with no air-conditioning, your GPU will shut itself down once it reaches a heat threshold, at which point the failsafe kicks in and shuts down the card to prevent permanent damage.

If your GPU has a heat tolerance of say, 200 degrees Celsius before the failsafe kicks in to shut it down, adding four more fans and a liquid nitrogen cooling system is not going to do anything to prevent that shutdown if you take some action to send a heat spike to your card. Now, what all those extra fans and heatsinks will do is allow your GPU to cope with high heat over time by preventing it from ever getting near 200 degrees Celsius in the first place. This is dissipation rate, not heat capacity. These devices do not allow the card to operate at 201 degrees Celsius, they only help prevent it from ever reaching the temperature.

And that, ladies and gentlemen, is why I think heat sinks increasing the heat cap is a ridiculous idea.

p.s. Yes, I know giant stompy robots is also a ridiculous idea.

I would definitely encourage the devs to consider some changes to the current heat system. First and foremost is getting rid of the ghost heat penalties, it was a bandaid not a long term solution.

After that they can play around with having heat sinks not increase capacity and only dissipate, maybe even make it so weapons build up a certain small % less heat as you increase heat sink quantity. I'm sure there's plenty of things they could play around with to make it more interesting.

Additional heat mitigation equipment, whether it be liquid nitrogen for a video card, or a heat sink for a fusion reactor (that's what the heat sinks are cooling) will cause the throttling / shut down point (95c for most video cards, God knows what for fusion reactors) to be reached over a longer period of time, JUST LIKE HEAT SINKS DO IN MWO.

And Giant Stompy BATTLEMECHS (they aren't ******* robots dammit!!!!) are a FANTASTIC idea!!!!!

Applying logic to MWO game design is pointless. for example weapon accuracy is perfect at max range. and ghost heat violates principals of thermodynamics.

The capacity concept comes from the devs not understanding the TT rules and fused the 30 heat auto shut down limit with heat dissipation. this group of developers are great programers but really bad at game design and project management.
yes i work in development.

You'd be amazed what computers can do out on the real field of war. While I've never been in an M1 Abrams tank I hear its pretty accurate even at speed.

yea we covered this topic (6-8 months ago) more like 12-18 months and pulled out the real ballistics data from the US army and guess what... the M1A1 has a cone of fire.... but no one wants to hear that. and no i'm not amazed that the M1A1 can hit a target at 8000 meters.

its because the devs don't seem to understand that in the battletech universe heatsinks are not really heatsinks, they are heat pumps, and they seem to like alphastrike warrior online.

MWO has a pretty true-to-TT heat capacity, the only difference is in the pilot skills, which add up to 20% to the total capacity.

TT: # of SHSE + 30 = cap.
MWO: # of SHSE + 30 + pilot skills = cap.

What MWO does not have, and why so many feel the heat system is broken is a dissipation to match the heat generated by the weapons.

TT: # of SHSE = dissipation per 10 seconds (or # of SHSE/10 per second).
MWO: # of SHSE = dissipation per 10 seconds (or # of SHSE/10 per second).

That's great, right? Exactly like TT. Well, yes, but in MWO weapons fire 2-3 times faster than in TT, so heat generated is 2-3 times higher. This means MWO dissipation is 2-3 times too low.

Neither does MWO have heat penalties that match the TT system.

TT: # of SHSE + 5 = start of heat penalties (remember, cap is 25 higher than that number).
MWO: # of SHSE + 30 + pilot skills = start of heat penalties (same number as the cap).

If MWO had the same heat penalty system as TT, heat penalties would start at roughly 40-60% heat, and get increasingly worse up to an automatic shutdown at 100% heat.

I for one think MWO would be a better game with proper heat penalties and faster dissipation.

no, mwo heat capacity is not even close to tabletop. tabletop heatcapacity is 30. it never increases or drops, because in tt heatsinks only increase heat dissipation. heatsinks dissipate 1 heat(or 2 in the case of double heatsinks) every 10 seconds(which is equal to each turn).some people just cant get their head around the fact that this is not an increase of heat capacity, its translating realtime heat dissipation into turnbased system.

And if you really think that being penalized when you reach @40% (and it gets worse after that) of your fighting capacity would be a good thing, then be prepared for Pop-tart Maximums Online, as firing your weapons, while moving about would be a suicidal action that many Pilots, well all Pilots, would give up in a heartbeat.

You're talking about the heat scale; that's residual heat, i.e. heat that is left over when the heat sinks have done their job. You add up all heat generated, subtract your heat dissipation, and any left over heat is recorded on the heat scale. Next round you suffer any heat penalties your residual heat confer - and then the cycle continues.

Heat capacity of a TT 'mech is the number of single heat sink equivalents (SHSE) it has + 30 (the heat scale); this is how much heat it can generate in a turn without hitting the automatic shutdown limit of the heat scale.

Heat capacity of a MWO 'mech is the number of SHSE it has + 30 + pilot skills (another 20%); this is how much heat it can generate without risking shutdown.

How much heat can a stock AWS-8Q (22 SHS) generate in TT before a non-overridable shutdown?
22 + 30 = 52.

How much heat can the same stock AWS-8Q generate in MWO before an overridable shutdown?
22 + 30 = 52.

Same capacity, although the MWO one can go past the shutdown if the override is pressed (and it will take internal damage from doing so).

The problem in MWO isn't the heat capacity, it's the dissipation which does not match the increased heat generation from raising the rate of fire of all weapons, and the lack of any heat penalties before hitting the cap.

Remember that those numbers are for residual heat as explained above. Before getting to 1 on that scale you had the entirety of your heat sink capacity to cool you.

And I don't share your bleak outlook on how it would affect MWO; getting hit with modifiers to aiming would be quite devastating for poptarts (c.f. jumpjet reticule shake), getting hit with movement penalties would be worse for assaults than for lights, and either way managing your heat is such an integral part of the BattleTech Universe it should be something you get penalized heavily for not doing well.

yes it would be fun, and it would make piloting mechs actually feel more like piloting a mech, and less like playing call of robots.
