want to upgrade heatspreaders for RAM, which one is best for me?

Corsair Dominator Memory Airflow Fan CMXAF1 at TigerDirect.com

Newegg.com - Thermaltake CL-R0026 Aluminum Heatsinks only - Memory & Chipset Cooling

i want to get the Corsair one when it becomes available again on newegg. My RAM get warms and i need it to get cooler. PC was unstable at higher clocks presuming that the RAM was too hot. Which one is the better solution? I save money with the Corsair n that one goes over all four RAM slots.

EDIT:

added a pic i got a while back just to show how my airflow is:

EDIT: Seeing the picture... the Dominators.
You dont seem to have too many wires and such crossing over everywhere and blocking airflow so the fans will be able to do their job.

i agree w/ zedman, ur rams already has heat spreaders on them so just get the fan.
