I fly a Zodiac CH601XL. Recently, I flew it from KFFZ (Mesa, AZ) to KBRG (Belen, NM). In spite of the fact that I typically flew at 10,500 or 11,500 MSL the air temperature in the cockpit was about 100 degrees. That was true even when the OAT was about 40 degrees.

The plane has two eyeball vents. However, they do almost no good in bringing cool air into the cockpit.

Does anyone have recommendations for reducing the air temperature in the cockpit? Thanks!

UPDATE

In response to my previous posting (see above) I received several very helpful suggestions, including:

1. Drill a 3" hole in the aft bulkhead of the baggage compartment to promote adequate airflow through the cockpit.

2. Install larger eyeball vents.

3. Install Vans vents on the sides of the cockpit.

4. Install a Koger ventshade. 

I will try these and provide a report at a later date on how they worked!

Thanks to everyone who offered useful recommendations.
