Cooling Issues i7 6700K

So the temp gets up pretty fast then gradually increases for a bit then levels out around 84°C. Here's the graphs of it ramping up:

It is especially warm today - probably 24 or 25 inside for reference.

This is:
100.0 base clock
x42 multi
vcore set to auto (currently @ 1.312v - 1.328v according to CPU-Z)
LLC is set to auto at the moment (I will try adjusting this again later)

This is perfectly stable, but I still feel that the temps should be lower on a Skylake processor running with an AIO. The pump speed is set to max so if the flow rate is too low, then I'm not sure what to do beside contact Corsair.
 
Hot weather, running max on all cores it seems (stress test?) and auto voltages which is likely pumping in more volts then needed, combined with the mediocre TIM application inside the 6700k's likely explains the high temps.

The cooler and water in the cooler, in the what looks like 30 second window you did that test with the attached graph is right is unlikely to have even changed a degree so makes no difference if fans / Pump was running full whack, rather issue is mostly above reasons. I would look at dialling in manual voltages, no doubt you could fine tweak it to be lower the what Auto voltages is doing to shave a few degrees is low.
 
Yeah, the graphs were only there to show the ramp up - although i don't know how useful 30s is for that as you say. I left the stress test running for 30 mins and it was pretty much locked at 84°C. It seems that I lose stability under load almost immediately when I adjust the LLC or vcore - but i think that's just a matter of fine adjustment. I will have more time to play around with that later this week and yes, I absolutely need better TIM. Will start doing some research on that I think.
 
No research needed. Get some kryo.

And all AIO aren't made equal. The one you have is probably bottom of the rung for cooling...
 
Indeed, all AIO are not made equal, but mot CLC of same radiator size are 3 basic designs; Asetek, Apaltek and CoolIT and use aluminium radiators with very low powered pumps .. they are made to last a couple years. AIOs that are not CLCs like Swiftech H220 / H240 / 320 X2 & X2 Prestige, Fractal Design Kelvin, be quiet! Silent Loop and AlphaCool Eisbaer all have copper radiators and pumps with about twice or more the flow rate of CLC pumps. Even when pump specifications are limited we can get a pretty good idea of their ability based on their load rating in amps .. and the ones that give any pump specifications at ll show the pump amp load rating to be about half or less that of the AIOs.
Important Notice:
This is a work in progress. If you have any AIO &/or CLC pump &/or radiator specifications for systems not included please let me know.
Also if you find any errors it is extremely import that you let me know.
Thanks!

Some solid info here - many thanks for that!

I have had some time to play about with the PC this weekend - I flipped the fan config into push rather than pull and have set LLC to 5 and VCore to 1.32v. This was previously unstable, but it seems perfectly happy at the moment running at 4.2GHz. I will get some new TIM at some point and apply that. I'm still not sure what I'm going to do case-wise yet, I will probably stick to my Prodigy a little longer and keep running the H80i with that, but I am enormously tempted to move to the Evolv Micro-ATX and get a 240 AIO at the same time.
 
This year my room temp is up more than normal, so my dam pc temps are too. More noise from the gpu is the biggest problem.
