I'm running at 4.4ghz with 1.235v and maintaining around 75c with prime95. Once stability was achieved, I increased the voltage to 4.6ghz at 1.35v, showing a noticeable rise in MHz but only a slight change in voltage. Temperatures stayed near 93c. I'm wondering if increasing voltage with minimal gain makes sense, or if reducing it could help. Maybe downsizing the CPU would be better?
Also, does using a liquid cooler affect the temperature drop? I'm currently using a Hyper 212.

I agree, if it takes that much voltage to reach the next multiplier it wouldn't be worth it in my opinion. That's a common scenario when the cpu hits its performance wall. Two things affect overclocking safely, heat and voltage. You can't keep pushing the cpu once either becomes a problem and in your case it's voltage. Since it's not overheating a larger cooler won't get you any further along, you're reaching the voltage limits and 1.35v is pretty aggressive for a 3rd gen i5. 1.3v is considered by many as the upper safe limit for 24/7 use on haswell/devil's canyon and for skylake it rises to 1.35v.
As far as delidding, I wouldn't. Your temps aren't a major concern, it's not going to get you any gains in the overclock so it's all risk...

i recommend liquid could cause a temperature drop of 1-3 C, making it unprofitable.
