Back to original issue of hot RAM, depending on what you have for space inside and how much it would bother you to have a muffin fan mounted inside. I have zip tied muffin fans to the hard drive cage before 90 degrees out from relation to hard drive(s) and added airflow to a warm/hot air pocket inside my case before.
This may look worse than the original clunky cooler or it might work better if you dont mind a extra muffin fan with zip ties in the case and wire management that keeps wires out of the fan blades.
I have put together some interesting cooling mods before to keep components cool. Even took a slot fan which normally would be placed along side a video card for extra airflow and took a home depot mailing which was a 5 x 8 index card material and cut and shaped and taped that to the exhaust side of this slot fan making a 90 degree bent air ram to allow the slot fan to lay on the bottom of the case and blow air upwards from bottom of the case across the surface of the motherboard towards the fan at the power supply at the top of the computer to better assist in internal airflow to keep everything cool where my Bridge controller was running hotter than I wanted and I was able to drop it from 70-80C range down to 60-70C range of thermal operation.
Couldnt find a picture of that, but these others show some cooling mods. Mufffin fan zip tied near cards, one held onto a video card with rubber bands where the GPU fan failed and a Pentium D heatsink added to a Core i5 laptop that was running over 85C and I got it passively cooled to 48C with a massive block of aluminum where the heatpipe based laptops CPU/GPU has failed leaking out and drying up causing thermal shutdowns until this was added with some thermal compound when messing around to see if I could passively cool it. The spikes on the display are thermal spikes when removing heatsink the temp climbs instantly and when placing it back down to draw away heat it levels out.
