Just to update and not leave a problem unsolved: i have had little time to look into the problem, but i have put a scope on the signal wire, and did not see any interference besides a lowering of voltage. possibly interference from magnetic inductance of the motors?
Either way, i have mitigated the drop by routing the wire through the front, away from the stepper motors. Since it is was long enough. The temperature response and prints have been absolutely fantastic since then.
I'm surprised others would not have this issue though when routed by the stepper, even if to a different degree. A quick way to check,when steppers are off, is to send G28 (autohome) through pronterface and closely watch the temperatures(should jump instantly).

I've seen other posts of this problem but don't know if they found a solution but I recommend you search and post in that thread to see if the original poster figured it out.
