Probably so, if you don't run it past 160 something or so. The LE comes with a little dinky heatsink, and I ran it for benchmarks up to 185 or so, and it still didn't have artifacts, but ran hot.
However, a small 40mm fan won't put off much sound, any airflow is better than none.
One good thing is the Radeon dosn't put out much heat.
