What's the technical name and where can I find these? I have a thick Fan that I use for my CPU cooler's radiator and I cannot find the right screws, I want a create a Push and Pull with a fan on each side.

Technically, they are called coach bolts. Probably cheaper to buy a length of threaded rod, cut it into the lengths you need, and use nuts, and washers.

You can get away without the shoulder on the screw as long as the threads match the threads in the radiator. Just make sure the length is the same to avoid damaging the radiator. You should be able to find what you need at a decent hardware store.

LF, I think what you call a shoulder, is what we call a head. And looking at the pic, I think it is blind holes. (difficult to tell)

By shoulder, I'm referring to the unthreaded portion of the screw. I'm guessing you are right about the blind holes which is why I said the lengths must match. One advantage to your suggestion about using all-thread is the rods can be preinstalled in the radiator and the fan slipped over the rods before inserting the rod ends into the case holes; 'twould be less of a juggling act.

LF. Yes, we call that bit the shank. And screws are threaded all the way up (except for the older type of wood screws) while bolts have a shank.

It's also called a shank here. Six of one, half a dozen of another although shoulder is also used to refer to a precisely machined shank, often larger in diameter than the threads. Wood screws here still have an unthreaded shank and a thread that is tapered at the end. We can still get drill bits that have the same tapered end here.

For those wood screws, 2 different sizes of drill bit, and a countersink bit. I know. Was trained by experts.
Although 3 in 1 bits did exist at the time, they were very expensive.

Haven't seen a three in one in years. Those are more common in assembly line work. More common now is to use the tapered bit to drill the pilot hole and a straight bit to open up the clearance hole for the shank. A separate counter sink is cheaper but the pros use a counter stop countersink that slips over the bit and both acts as a countersink and a bit stop collar. I was also professionally trained and worked in cabinet shops for a while after getting out of college.
