Issue with overheating dual LV-N's

[SDIR]

I've been playing KSP for a while now, but with the release of 1.0 an accurate thermal model, I now have issues with overheating on any useful burns on my space tug. The dual engine setup overheats between 1:30 and 2:00, almost 100% of the time, regardless of whether I add smaller 1m fuel tanks in front or the precooler module, and even wings that should help cool it doesn't help either.

I'm at an end, and I can't figure out a solution while still using two engines for higher acceleration.

I've included pictures of the engine layout that I currently use.

This has been a problem with LV-Ns in general ever since 1.0. Current solutions include using a massive fuel tank as a heat sink, surrounding the engines with wings (the wings act as radiators), and/or bugging Squad to reduce the amount of heat generated by LV-Ns.
