In my experience, it's more than enough on an Anaconda. Dirty drives on smaller thrusters don't generate that much heat on it. I'd also recommend spamming the dirt cheap G1 Low Emissions power plants until you get a secondary effect that actually increases your power capacity slightly above stock. That way, the only downside you get is the smaller integrity.I have not tried both options myself, but I will give you my thoughts on the matter.
I don't feel that Dirty Drives (specifically on an Anaconda) are worth it if you are using the ship primarily for Exploration. If you did go Dirty Drives, you would almost certainly have to Engineer every other part of your ship possible to generate less heat. This would likely include using a larger Power Plant, and Engineering for Low Emissions (which would also likely reduce the power output), and I don't know if this would be enough to offset the heat from the Dirty Drives.

However, getting an increased thermal load effect on your FSD will be noticeable. In that case, unless you have top-end results in optimized mass and/or a max fuel per jump effect, I'd recommend re-rolling.
But thankfully, the Anaconda generally has pretty good heat management, so you'd really have to go out of your way to have heat be a problem on an exploration build.
Thanks for the great info. I am running 5 D Thrusters right now and the dirty drives might give them a bit of much needed power. Thanks.
