Brand new fan clutch - overheats at idle?

[JJorgensen52]

So I just switched my OEM fixed fan for a clutch fan setup tonight. During the process, I swapped the clutch for a new one (TorqFlo unit from Autozone). I noticed when I pulled the clutch from the box that there was a small amount of fluid on the face of it, but nothing that seemed significant.

Installed it, works great, my truck doesn't sound like a turboprop anymore on the highway, but I'm now overheating at idle. Or, at least it got up to the end of the green zone on the gauge and I chose to not see if it would stop . I had zero issues before I swapped fans.

From the reading I've done on clutches, it seems that if the fluid leaks out, they won't spin as fast as they should, thus causing low speed overheat.

Has anyone ever had this experience, a clutch bad right out of the box? I'm going to see if I can return it tomorrow and get one that doesn't show signs of leakage - any other suggestions?
