I am on 4.4ghz with 1.235v and hovering around 75c with prime95.After i got that stable, i managed to push the CPU to 4.6ghz on 1.35v, a big jump in the voltage but a small leap in the mhz. also was hovering in the 93c.

To me, i don't see the point of putting that much voltage on so little gain, but again i want to know what are your thoughts on this.

- Maybe my next step would be to delid the cpu and hope for a 20c drop ;)
- Would a liquid cooler have any impact on temp drop?. I'm 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...
