I just noticed that Cooler Master has a low profile HTPC cooler called the Vortex Plus on the market for $29.99.
Vortex Plus is a low profile CPU cooler with compact size and uncompromising cooling efficiency. The compact features best suit a new generation of desktop platforms in HTPC chassis. The heatsink maximizes heat conductivity with 4 direct contact heatpipes. A 92mm Blademaster PWM fan provides both high airflow at high RPM and quieter operation under lower speed.
