High Temperatures With New Setup

[Some Damn Author]

Hey there! I have an Nvidia Geforce GTS 450. (Yes, I know @.@)

Previously, I had a Core 2 Duo Intel CPU. Normal temperatures of the card were at 39-45 degrees, and while OC'ing, went up to a max of 57.

Now, however, I've changed my cabinet and have an i5 4th generation. Mysteriously enough, even after cleaning and keeping my cabinet open, normal temperatures are not dropping below 55. And when I game and OC, it reaches a max of 72. Is there any reason for the temperature being generally higher in my new setup, or is it just a problem with my card?

Is the heatsink and the CPU fan in place correctly? If not, remove and reinstall the fan. Try applying some Thermal paste on the CPU. Does your case have good air flow? If not, try some cable management (using zip-ties lol 😛)
If all else fails, try running it on stock speeds.
Hope this helps.
