The problem is, there is, say 1 kg of hydrogen at -200 C, and 5 kg of pipe at 0 C. The simulator behaves as if there's just one gram of hydrogen in calculating the heat difference - how much energy it takes from 1 g of hydrogen to exchange heat with 5 kg of pipe. Well, it's pretty small amount of energy. And it then draws this amount of energy from that 1 kg. That's why the heat exchange in pipes is so slow.

Does that make it better to run low masses of hydrogen thru pipes for radiator style cooling? i remember seeing a previous post that suggested thermoregulators take into account the mass of the gas running thru it, so wouldnt they heat up less if you're only feeding a small amount thru and still cool the pipes by the same amount?

No. The effect just limits the amount of heat that can be transferred per second. It does not affect heat contents or thermal inertia of the medium you use. If you send 1 g packet of hydrogen to the pipe, it will exchange all its heat in first pipe segment and then it will be useless.

I was thinking for smaller applications, more like 250g/s over 40 pipe segments - like that you might still get about the same amount of cooling but thermal reg might not overheat as fast since its processing smaller packets

Running 250g packets through them makes them 4x as expensive in terms of power per heat transferred. If you're not running them near overheat temperatures, it's better to send them 1/4th the amount of full packets.

You can use a packet combiner to combine smaller packets from pumps into larger ones, and also reduce the amount of packets coming through the line:
