Wow, this must be the highest amount of installed heatsinks i've ever seen.

[Arnold J Rimmer]

Once you get up into that many SHS, their benefits actually outweigh DHS. It's slow, but it'll fire all day.

[Leeroy Mechkins]

1.3-1.65 is the range I find useful.
<1.3 is too troublesome to use on hot maps
>1.65 is not really necessary.

Yeah. I think I've calculated that SHS start giving better heat efficiency than DHS with 28 or more (assumed 10 are in the engine). It's rare to find a build for which it makes sense to use so much tonnage for cooling, though.

Pretty much the only ones I've seen are one of Koniving's HGNs and this Boar's Head/Supernova.

[Parappaman]

0.93 heat efficiency on my LOLsome JM6-DD.

Problem?

I'd do this: http://mwo.smurfy-ne...fe367bfc7204912

You're a sitting duck with that small an XL engine in an Atlas (and many say that you're foolish to put an XL in any assault at all). If you're going to take that kind of hit on survivability you might as well be fast (for an Atlas) while doing so. It's also cheaper by about 3 mil C-bills if you don't already have an XL 255. For DPS purposes you're probably better off doing 3 groups of two to avoid the heat penalty.

I've found that once you've used that much tonnage for SHS you're better off going with Endo Steel, DHS and a larger engine. It's very very rare that you can't achieve greater heat efficiency. And even if you can't get better heat efficiency the trade off in speed is more than worth it.

Generally, I agree, but have you seen his build? There is no way you can get anything remotely similar with DHS: http://mwo.smurfy-ne...ba740b7fdc0201e

[Dugra Dugrasson]

1.11

[kevin roshak]

According to the mech lab my lowest is 1.2 (~33%) and my highest is 1.29(37%)

[Galen Crayn]

It depends on the mech you play. With my Spider i wouldnt go under 1.4 - i have 1.57. Why? Because i want to shoot all time. With my spider the damage record is nearly 800 in a match - impossible with heat 1.1 to 1.4. With bigger mechs and bigger alphas lower heat is ok but i personally would never go under 1.4.

oldschool stuff. loved doing this in MW2 and it worked! heavies and assaults all used to be able to find a use for SHS in exactly this way but now just try:

prolonged life and over 10% speed boost! - swap 255xl for 325 std engine

almost as good - now swap SHS for doubles. you'll see the initial perk spike as the engines heatsinks upgrade, you can only add about 6 more so external DHS but then you can fit an additional 3 DHS on top of the engine, they rate at 2.0 unlike the externals. this made up perk of adding to the engines HS means your rating is almost as good as the tanked SHS but with the added speed boost and survivability of a std engine its a no brainer. sadley DHS will ALWAYS build you better mechs in MWO because of this customisastion layout. Believe me a drop of 4-6% in your CE is nothing compared to an Atlas held back by an xl {and speed tweek of only 45KPH OMG!}.

btw my 5ll stalker runs at 42% CE but ghost heat means i can really use the dps over ac's so it's a challenge these days to use it. i like a challenge and the inevertable failure but i like a challenge

i approve of the run hot or chicken out style of this thread!

I run from 2.0 all the way down to 1.1 depending on the mech. My lighter mechs tend to have a better efficiency but i think the 1.1 is decieving cause the weapon loadout is a mix of ranges so I almost never alpha strike so havent had an issue with it.
The minimum really depends on the weapons you load and what you are trying to accomplish I would think. My light mechs i tend to run with a high efficency cause I do NOT want to shutdown EVER but still maintain a decent amount of fire, my ballistic builds amost never suffer from heat except my AC2 builds and the assaults tend to fire different weapons at different ranges and even if I do manage to get everything lined up one or 2 aphla strikes pretty much kills what was in front of me giving me time to cool off while still firing and lining up the next target.

[ZBeren]

All my stalkers are around the 1.1 line and I do just fine. Firing discipline and proper grouping.

The build in your link has 39 heat sinks. The build with XL400, endo and double heat sinks has 10 internal with 2x efficiency and 11 external with 1.4x efficiency, which amonuts to 35.4. So the difference is negligible 3.5 heat sinks against 57% increase in speed (also turning speed allowing to defend with arms much more efficiently).
http://mwo.smurfy-ne...fe367bfc7204912

or as already suggested, you can use STD350 and achieve the same heat efficiency as with XL400, but you are much more durable, although slower.
http://mwo.smurfy-ne...97bf9fbf702d606

single heat sinks are just a waste and are in no way better in this situation.

[zagibu]

Hmm, you are right.

[TheFlyingScotsman]

I don't let myself drop below 1.5 with a steady dispersion rate. Typically 14+ DHS for larger mechs, 10 for mediums and lights. It works well for me.

STK-3F 'Tempest"

26% Cooling Efficiency
don't know how, but it still works good for me... just avoid the heat penalty of the 4 LLs, and be sure to hit when you fire, any missed shot is wasted heat capacity.

You can take out a heatsink put endo steel in and with a 275 with heatsink slot

Get the same ​efficiency with more speed capability and AMS

http://mwo.smurfy-ne...b1bae236672476d
You can take out the 1.5 tonns for AMS system for what ever you want

und here it is without AMS and more leg armor
