QUICK SUMMARY:

Richard told me I need to Keep and eye on LVEA Temps because A fan was shut off. we expect to see temps fall.

The temp in the Y Ebay seemed warm at 26.1 C. So I trended back the last 10 days and noticed that H1:PEM-Y_EBAY_RACK1_TEMPERATURE reached over 45 C in the Ebay. I'm not sure if that s accurate or not but it seems like something to make a note of.

H1:PEM-Y_EBAY_RACK1_TEMPERATURE seems too high when I compare it to H1:PEM-X_EBAY_RACK1_TEMPERATURE which hasn't changed more than a degree in the last 10 days. My Previous alog tags FMCS.
