I'm not sure if this is what you're supposed to do, but what I've personally done is just upped the thermostat. I believe mine is set at 116 and the hot side temperature in the tubs doesn't go over 92 even with extreme room temp fluctuations.
You may not need to bump that high with a helix though - my thermostat reads 116 but the heat tape is only about ~108-110. I think I buggered something up when I taped the probe down, but it's been working just fine if I keep the discrepancy in mind.
I'm not exactly comfortable keeping it that high and check obsessively throughout the day, but it's been stable for the last ~3 weeks.
I have the same issue with the tub sides. Sterilites are so blah.
