HDD in the 5.25" or 3.5" bay? (Airflow question, I know HDDs are 3.5")

This is a question about my future build, I like to plan ahead so I thought I'd find out peoples' thoughts on this before I build.
I'll be getting the Corsair Obsidian 450D case, and I'll also be using a single SSD, and a single HDD. The 3.5" drive cage can be completely removed to allow for better airflow, and the SSD can be mounted on the back of the motherboard tray.
So I was wondering, would it be worth mounting the HDD in one of the 5.25" bays (using an adapter of course) Or would the slight gain in performance not really be worth it?
I'm guessing the HDD won't get too hot in the 5.25" bay, since the SSD should be fine behind the motherboard tray with practically no airflow. I wouldn't be using the 5.25" bays for anything else.
Thanks in advance for the advice

I have never seen my HDDs vary in temperature. They stay pretty muck locked on 31 to 33 degrees. Same for the drives wedged in 3.5 inch bays. Same for the drive in a 5.25 inch bay. Just not much heat being generated.

The one that gets "hot" is an external eSATA drive in a metal enclosure with zero cooling. And, by "hot", I mean it hits 38C doing a full backup writing to the drive for a couple hours.

I don't think either way would impact cooling performance very much. If you don't view it as too much trouble I'd suggest you try it, and monitor the temperatures you are getting, you can then decide if you want to put the 3.5" back in or not.
