I was thinking of upgrading my K2 to a H115i. I am delidding my i5 4670K and getting new fan setup, so was thinking that watercooling might be good.

I have a Corsair 300R and it is compatible with 280mm radiators (although barely). I watched a youtube video and it seemed pretty straightforward albeit snug.

Does anyone have any benchmarks of the h115i and k2 mount doom together? K2 isn't hugely popular so having trouble finding consistent benches for the same CPU and conditions.

Are there any woes with AIO watercoolers? I know air is safer but I trust corsair and think that their reputation proceeds them. OcUK are doing a great deal for 49.99 on the h115i perf.

K2 is such heavy duty heatsink, that except for short load spikes that would be likely downgrade.
Here H115i RGB Platinum fails to exceed lot more modest (than K2) Scythe Mugen 5 in cooling per noise:

Wow that article man. I didn't realise it was literally a degree or two difference. I even learned that the h80i single radiators perform just as well as the h100s... why do people even bother going with water if the differences are fractions of a celsius.

Could you recommend anything els to lower my temps?

I have a really **** chip and need 1.35v to hit 4.4 lol. I am going to delid it with liquid metal next week, got a bunch of nonconformal coating and I want to stick liquid metal between the cooler and the die as well. I'm buying Artic p5 (?) 140mm fans for the front and top intakes. My PC is sat on the floor in the corner, I am thinking of cutting out some mouse pad and raising it a few cm to help with airflow too.

Is it worth sticking fans on the side? My PC fits in the cutout under my desk so the sides are covered only rear and front are available. I was thinking of putting my PC up top but it takes too much room and I'd need a whole new wiring setup for everything to fit properly.
 
Waterpipes in place of heatpipes simply don't make heat disappear anywhere, regardless of marketing hype.
In continuous load that heat has to be dissipated into air and smaller/slimmer radiators simply don't have excess of surface area.
Sure ~2k RPM fans help in that, but those also make lots of ruckus.
(and would also boost performance of heatpipe coolers)

Intel's bubblegum/toothpaste going bad under the likely sloppily attached heatspreader can well be big culprit to temps.
Replacing that likely helps good amount.
Though notable overvolting is never good for keeping temps low.
Power consumption and heat output rises at least to square of voltage increase.
More likely more because linear scaling of current draw applies only if resistance stays constant.
And suspect that insulation resistance of semiconductors decreases with increased voltage.
Higher temperature itself increases leakage current further and makes also transistors switch states slower consuming more power.

Improving case cooling is another thing.
If ambient inside case increases 5C, that's directly reflected in CPU temperature, unless CPU cooler's cooling power is increased.
(bigger heatsink and/or faster fan speed)
So if case has restricted intakes and dust filters (which get clogged) fans capable to higher pressure are needed.
Arctic P14 has good design for dealing with airflow impedances.

Also replacing crappy stamped meshes of case with good old wire made finger guards could help.
Some cases have simply horribly restricted fan positions, so what case you have?

I have the Corsair 300R

Do you know if u. An buy any wire guards
