Hi zknurb‌,

First of all, what's the system model?

Also, try running an ePSA/Diagnostic test on the system, click here to view a Dell article that explains how to run this test. Let me know if you receive any errors. 

I'm guessing you mean Aurora-R4.

Possibly.
 
Some old Asetek pumps fail or get clogged-up. Search here a bit.
 
IIRC, the symptoms are:

- Radiator fan at high RPMs

- One tube is really hot while the other is fairly cool.
