Thermaltake lanbox lite cooler options

Hey, i have a question regarding cooling for my lanbox lite case.

Here's my current specs:

E8400
Asus P5Q-EM
2GB Kingston HyperX 1066

I'm currently running the stock cooler and at stock speed was running about 41C idle. I overclocked it to 3.6 and the idle temps are sitting at 59C.

I ran a temp sensor test in realtemp and the temp got all the way up to 96C I'm not sure how accurate that is considering the e8400's are notorious for showing whacked out temps. the bottom of the case where the processor sits was warm to the touch....but no where near what i'd expect to feel if the temp truely was 96C.

I know this case isn't known for the greatest airflow, but i'm looking for a cooling solution that would help lower my temps a bit. If anyone knows of a good cooler with a slim profile that will help lower the temps in this case a bit i would appreciate any opinions.
