Is My OC Causing High Temps?

I have little experience with overclocking but I managed to get an overclock of 50% on my CPU using some manual input. this gave me DRAM:FSB Ratio of 1:1 However, in doing so I think my temps might be high and would like the input of someone more experienced. My system doesn't give any problems until I run Skyrim on high (not ultra) settings. There is delay and stuttering when loading into a town or out in the open. Being inside a building or cave it disappears.

Current temps are linked here:

Any comments would be greatly appreciated!
