My current clock speed on my Intel i5 4690k is 4.2ghz. For cooling I have a corsair h90 the highest temp I have seen was ~40°c while playing bf4 on ultra but my cpu is still at 90% usage. Would I be able to over clock my speed more to 4.5ghz or maybe higher I am not sure, this is the first time I have overclocked so I could use some tips and tricks, thanks in advance.

That depends entirely on your individual processor. An average 4690K will hit around 4.4, but there is considerable variation. See how high it goes on the stock voltage, and then you will need an additional 0.0375-0.075 volts for every 100MHz above that. It's recommended to stay under 1.3 volts to preserve the lifespan of your CPU. Also, don't start overclocking the cache until after you've settled on a safe and stable core clock and voltage.

Hi there, here's what I can tell you.
A lot of things can effect your overclocking limits, including things like PSU and motherboard.
As mentioned above, your 4690k can reach ~4.4 ghz with an average cooling system, and considering that you're watercooling (albeit closed loop), I would put my money on being able to reach 4.6 ghz.
However, every chip is different and you might not be able to reach this number (or might be able to easily).
For tips on overclocking, disabling "CPU Spread Spectrum" is huge, and other cpu options in the bios. Here is a good video tutorial on how to change these settings in your bios, although it changes a bit from motherboard to motherboard. (https://www.youtube.com/watch?v=Qcta3RStYSM)
Once you've done your overclocking (say to 4.5 ghz) you need to check its "Stability" with some software like Prime95. By running a Prime95 stress test, the application will let you know if the check "failed" or simply give you a blue screen or freeze your comp. If that is the case, you need to pull back the overclock to something lke 4.4 ghz OR increase the voltage, which you can learn how to do (in very small increments) in the video above.
Normally, overclocking is very safe unless you really screw up the voltage, which is very hard to screw up if you increase the cpu voltage in very small increments and monitor your temps when running prime95.
All in all, good luck. I think you can push it further. Don't give up either, some of my best overclocks took ~6 hours messing with settings.

my motherboard is a msi z97s sli krait edition, my psu is a corsair cs650m. I ran prime95 when i had overclocked from 3.5 to 4.2 and i ran it for ~45 mins and if my memory serves me correctly it was at or around 40c at full load. is there any way that i can maybe get around increasing the voltage because i don't want to screw around with it and fry the processor.

Unfortunately, no. There is no way to increase your overclock past ~4.2 ghz with the default voltage.
Fortunately, I can assure you that changing your voltage is very safe if you do it in increments of 0.005 volts (or whatever the minimum increment is for your motherboard).
How can you tell if your voltage is too high? If the temperature reaches past 70c or if your computer crashes.
I know it's scary the first time around, but there are ways to avoid damage as mentioned above.
Good luck overclocking!
