How necessary is a p/s cooler?

[BR3W CITY]

I've never run one in this truck, but since putting my hydroboost brakes in, the power steering can get pretty darn hot. You can actually feel the heat off the pressure hard line from the booster to the steering gear.

I'm not familiar with heat issues on power steering systems, and mine seems to function just fine (actually over-boosted, which I need to figure out as well).

So, do I need a power steering cooler, or is the heat just a by-products of the new booster, and just a fact of life.

i was told by the tech at hydrotech that u need a cooler
, all factory setups have one but drive it around and if it burns the fluid or turns to tar like add one
