so I have one of those hail protector bubbles for my dd.
it has 4 radial fans in it. 12 volt dc 1.5 amps per motor.
one of them failed.
I went to look for a replacement and cannot find that exact one.
The closest is a 1.8amp 1.5 amp run motor instead.
I contacted the company to buy a spare but they want 150 for all 4 again.

They said not to replace a single one with something different because
"The blower is built to our specs and it’s very important to match blowers due to imbalanced power consumption otherwise."

does this really matter?
It is a brick laptop style power supply.
