Northbridge Cooler...Recommendations ?

[PING MCS]

...with Silverstone Op750 PSU
eVGA 8800GTS
Nitrogon NT06 CPU cooler
I can't think of anything else that might get in the way.

I'd like to bring my Northbridge temps down a 'lil bit.
Any suggestions for a cooler.? Active or passive, doesn't matter. One that simply does a good job will do.

Thanks
