PowerEdge T620 Heatsink Question

Hi,

I have no sticker on my heatsinks saying "airflow" with an arrow pointing in the actual direction of the airflow, so I am not sure which direction the heatsinks face!?

Thanks,

G

P.S. YES, I have done it again. Taking something out of my T620 without taking a picture first! How stupid. My plan was to take the heatsinks out and put them the exact way on top of the computer case. I did that. I know that the left heatsink is facing with the sticker in the 6 o'clock position (so you can read it). I am sure I put the right heatsink on the case the same way it was mounted. But guess what!? I then moved it into the kitchen to clean it. I then realized that the CPU's are not facing the same direction which now completely confused me!

I believe the heatsink were mounted where BOTH the stickers on them are in 6 o/clock position. But I am not sure. The attached pictures is from the internet and shows how I believe they should be mounted...
