I like the katech 174* with moderate fan settings runs 188ish. The temp is stable in the summer too especially on E
Thanks, so I guess they are having issues with these from the factory, that's surprising.

So they are just leaking by the seal? Or was there something else going on with the spring or something? Or I guess you just swapped in a new one and didn't really know the cause?
