Mounting Fan on Concrete Block Partition Wall

I have a fan I want to mount on a concrete block partition wall. I have no idea if the block is filled or not. The fan will ventilate stationary bikers in front of it.

The fan is about 15 lbs. and has 3 vertical mounting holes. It does not oscillate but I certainly don't want it to fall from vibration.

What's the best way to mount it? I don't want to use wedge or expansion anchors as I don't trust my experience with these, but I was considering....

--3/8 Carriage bolts through the wall and lock nuts on the other side. (How long would I need bolts to be?)
--3/8 molly or togglers, OR one these as in the PIC with a lock nut.

What would you vote for? Thanks!

Mollies and togglers would not be my first choice.
There are fasteners that will work well in block.

Carriage bolts would work. Longs bolts will work too. The blocks are 8" thick.
You'd need 3) 9-10" bolts..... probably 5/16 - 3/8" diameter.

You could also buy one 4' piece of 5/16" threaded rod. Plenty for three fasteners.
Get some nuts and washers and you're set.

Since the fan is so light..... 1/4" hardware would work too.
