I flew too close to the sun.

[Newt Loranas]

Quite literally, I came out of hyperspace and forgot to throttle back and got an emergency drop from supercruise.

Since I gave my T6 a grade 3 Increased Range upgrade, the FSD overheats like crazy, this is not normally a problem but now being so close to the sun It IS a problem.

Indeed when I dropped from SC my temp was at 140% and I took a lot of module damage which seemed to mostly concentrate on the cargo hatch which is now at 54%, other modules are 70-90%

This caused me to vent my cargo, which included a number of modular terminals which I would rather like to keep. I recovered the terminals and left the rest.

I'm currently at 240m/s flying towards Ashby City and away from the sun but the ambient temperature is 64% and my ship hits 98% when the ambient is 50%.

Will disabling the cargo hatch help prevent it from venting ?

I know for a fact if I supercruise I will take more module damage and I suspect that no matter how long I fly the ambient temperature is always going to keep my ship at 64% because 240m/s is just too slow to travel significantly far away from the sun.

Sensible suggestions / sympathy greatly received.

Power down every module you don’t need.

You only need thrusters, sensors, FSD and could probably switch off life support until you’re in SC to help save the heat from that too.

This ^^

This would seem sensible.

^^this is what I'd do to try reduce further damage/keep temp lower during FSD spool-up. (Turning off the bog light on the ship will also help)

Superb! Thank you for that. I will very definitely give that a go as it's clearly the only option.

 

[Newt Loranas]

well it's was worth a try. at least I didn't explode.

I did take more damage, specifically to the cargo hatch which dumped cargo in supercruise and out of a choice of 4 remaining commodities it ONLY dumped the modular terminals lol.

I am going to go and get a new FSD upgrade and see if I can hit one that doesn't have such a terrible overheat issue. I must have had an unlucky secondary

certain powerplant upgrades can badly effect heat and also if you are drawing over 100% power from it (have you upgraded the PP or drawing too much power?)..

 

[GunnerBill]

'A' rated power plants run the coolest. And to avoid any integrity or heating issues I use un-engineered PP's that cover my power needs rather than using an overcharged smaller one.

You might want to think about switching off the life support as unless you have synthesis for it it will eventually run out as it does not recharge when you turn it back on!!

 

[Maymo]

I’d leave the FSD alone and take a second look at your powerplant, sounds like it needs an upgrade, you’re not still running a 3E are you?
I usually use a 3d power plant on my Type 6’s and don’t recall heat issues, even with a G5 FSD.

Edit: c3 not c4

 

[Newt Loranas]

I upgraded the power plant too. It's got a grade 3 overcharge and my T6 uses a total of 99% of it. It's a 3E PP, it only got that overcharge because I was levelling up an engineer. I should probably fit at least a 3D and overcharge that.

Just looking at the mods the power plant has

mass -8.5%
integrity -29.7%
power +22.5%
heat eff +27.9% which is a bit rubbish on the heat.

and that's combined with the FSD's heat per second being 19.0 ( +5.7%)

 

[WR3ND]

I've heard Type-6s run rather hot in general too, so you might try a different ship.

 

[Maymo]

Wow, what do you need all that power for? Have you fit a larger shield generator for it?

A quick suggestion...

Just fit the 3A power plant and throw a load of G1 Overcharged rolls at it. It shouldn’t take long to get an increase in heat efficiency AND additional power.

 

[Dirtbird]

I think you really would need to be a 3A power plant here, mostly for the heat efficiency. You can then engineer it for extra lightness, etc. afterwards.

 

[Newt Loranas]

It is running a
Wake Scanner
SRV Hangar
Class 3D shield
3A Power Distributor - Engines Enhanced - just because I was levelling an engineer

Not seen a mod for lightweight reactors.

I'm using it for (non combat) missioning in Luyten's Star while I build up rep and modular terminals for sirius corp.

I will ditch the chaff and point defence as not needed and fit whichever unmodded reactor will fit the power requirements

**I really need a second monitor again **

 

[Newt Loranas]

I was wondering if the T6 actually ran hot. I would concur with this.

Anyway overheat problem solved. I dropped in a 3A reactor which was more powerful, more reliable, more efficent and lighter than the modded E - don't even know WHY it had an E, I usually go for a D

 

[the100thmonkey]

Too close to the sun maybe, but at least you flew, proud Icarus.

 

[imski]

Do G1 rolls for Clean Drives.

It's not as good as Dirty, but the power efficiency and improved performance are hugely worthwhile since the thrusters are usually the largest heat generating modules on a day to day basis.

A few general notes on heat

Ship heat is caused by:
-Base heat for ship type
-Power usage (total)
-Weapon/Sys/boost usage
-FSD charging
-Powerplant grade


The FSD doesn't matter except for the power it uses and when it charges. The important one is the powerplant as it will account for a good 50% of the heat generated if not more. Difference between max power available and current power used doesn't matter. In the same vein the size of powerplant doesn't matter but grade does.

You've optimised well but that E grade powerplant sucks at heat management, to add overcharge mod making heat worse is a really bad idea. Go for an A grade, maybe even a size up, sell the E grade and enjoy the new air conditioning
Edit: I see you got the A grade, good stuff

The T6 isn't a bad ship type as it goes, not above average but not really below, and with a trading loadout shouldn't generate too much heat.

 

[Siranui]

I upgraded the power plant too. It's got a grade 3 overcharge and my T6 uses a total of 99% of it.

Try for A class plants - even if smaller - because they cause less heat. And use the lowest level of overcharge as possible for the same reason. Remember that you do not really need to have *everything* powered all the time in many ship types. How often do you use a cargo scoop at the same time as weapons, for example? At the extreme, there's even the old 'Run on emergency air when I deploy hardpoints' plan!

 

[Funny]

You... Overcharged... the least thermal efficient powerplant level in the game... You really must love cooking XD
Anyway, I’ll just drop this here: https://forums.frontier.co.uk/showthread.php/286628-Research-Detailed-Heat-Mechanics
Short summary of that thread:

• Each ship has its own heat capacity. The higher the heat capacity, the more a ship can cool per second and the more heat it can store before overheating
• Thermal efficiency determines how much base heat is generated from your power used

I’ll add to that that stars add heat to your ship independent of power plant efficiency or the likes, meaning that smaller ships will be less able handle fixed external heat than larger ships, on average, with diamondback as a noteworthy exception to more or less everything
Note: it’s possible that they recently changed heat dissipation to take surface area into account. However, that does mean that they also likely heat up faster from stars. The more likely alternstive though is that they arbitrarily assign a number to its star heat absorbtion. Either way, I’m fairly certain that the cooling is still dependent on heat capacity. Which makes no sense, but hey, FD doesn’t exactly give the same scientific treatment to their speceships as they do to their stellar forge
Anyway, I use that thread a lot when trying to manage my heat generation in combat ships and the likes. It’s pretty useful, though sadly doesn’t list the heat capacity for the type 6. I’m guessing it’s still pretty low.

Either way, if you’re using a lot of power it can be worth it to upgrade to a low emissions modification. Should help quite a lot then for cooling.

Note 2: on heat efficiency, the formula for hest per second from power is: heat efficiency * power usage. Since heat efficiency on e powerplants is 1, the heat capacity of of the type 6 is probably about 160, and the cooling rate thus about 13.92, and you even overcharged your powerplant so you were generating 1.297 heat per second per MW... It’s no wonder your ship was cooking so much lol.

The extra efficiency is more noticeable on larger ships, on average, because their heat capacity to power usage ratio goes waaaay down, making heat efficiency a lot more important, but on a lot of ships it’s still a pretty nice honus if you go for a ‘luxury’ setup over pure jump range.
