Pass Labs heatsinks temperature

This thread got me a little curious so last night I measured the temp on the cooling fins on both of my amps(XA-100.5's). I could find no area that was over 119.8F, the amps have been in stand-by mode for several days and had been fully on and running for several hours. Not sure if this will help but thought I'd toss it in the mix.

I am not using a baby thermometer, using an infrared. I've checked the temps up and down, front to back and all the different fins and the highest I got was the 119.8F. It's warm but not hot to the touch. I'm going to run them all day today and then check again just out of curiosity(sp?).

Magfan,
Ok, I went ahead and rechecked again as promised, I wanted to be sure my first readings were correct.

I'm using an infrared thermometer and checked from front to rear and all fins in an attempt to find the hottest point on the amplifiers. The hottest point does seem to be near the front panel in between the topmost and second fin. The amps have been kept in stand by for days, I set my cdp on repeat, left the house and let them run for several hours at a moderate volume. I got a maximum temp of 121.4F.

FYI; This is a new pair of amps that are only about two weeks old and I agree; I doubt that Pass would let a set leave the factory without checking and double checking the bias.(As a matter of fact I believe they set the bias, run the amps for 24 or 48 hours and then recheck again.)My needle hovers just to the left of the center line and stays there unless the volume is turned to an unbearable to me level. Though I know this is not much of a scientific way of checking for correct bias setting I hope this helps out anyone with questions on their amps bias setting. To be honest I think that Pass Labs class "A" amps just run cooler than most other class "A" amps.

I need to make a correction on my last statement; I meant to say that the hotest point is not towards the front panel but in-between the front panel and the rear, right about the middle and in-between the top and second fin. Sorry about that.
