Uneven Temperature of 2-channel Parasound A23 Amp

I have a Parasound A23 amp. I noticed that the right channel of the amp is so much cooler than the left channel.

I first noted this when I left the amp for a few hours yesterday. Nothing was playing - just that the amp was on.

Although a bit warmer, the right channel seems also cooler after an hour of playing music.

Has anyone experienced this phenomenon?

Is the balance control centered on your preamp, providing equal drive to each channel of the amp?

Are you using ceiling fans that would cool the right side more than the left and or is the right side exposed to free flow of air, leaving the left side restricted?

If you look into these two things the next thing to do is check bias.
