Is it normal for a newly installed front wheel bearing to run hotter than one that has been in for a few months?

I just did the driver's side yesterday. The passenger side had failed catasrophically a while back. I had someone replace it, and was under the impression that the driver's side might have been original, so I decided to do it myself. I replaced the races and ensured that the new ones were fully pressed back in. I did my best to push grease into the bearings from the seams on either side of the rollers, and pushed it in and around the rollers also. I put a layer on the races, and after inserting the inner bearing, I filled the recess before pressing in the retaining ring. I then reached my finger through the bearing and packed grease into the inside edge of it. I did a similar thing with the outer bearing. (I saw a recommendation that grease shouldn't be packed between the inner and outer bearings, as it would just heat up, expand, and bet blown out the seal). I torqued it to 41 ft lbs, backed it off 1/2 a turn, then re-torqued it to 1.5 NM as per Bentley. I had to tighten it slightly from there to reveal the hole for the cotter pin. I then filled the cap half full and installed it. There were no shims in the caliper mounts, and it needs some to be centered, but this was true before removing it also.

After my first test drive - about 4 minutes, including a 2 minute stretch at about 80 km/hr (5o mph) - I touched the dust cap of the new bearing, and it was warm. When I checked the other side, it didn't seem warm at all. I then took it for another test drive - about 5 minutes including 3 minutes at 80 km/hr - and this time it was a bit warmer (not too hot to hold my finger on it though), but the other side was starting to feel warm too. I started thinking that maybe the brakes were dragging on the newly done wheel, but the rotor surfaces seemed about the same temperature on each side.

Is it likely that the warmer results are simply due to the new bearing being tighter than one which is broken in? Or does it indicate that it's adjusted too tight, or that I didn't pack the grease well enough?

I'm going to try another test drive later, and I will try not to apply the brakes (will use handbrake) so I can verify whether the increased heat may be due to the pad dragging on the newly done side when the brakes aren't being used.

Thanks for your help,
