Am waiting for the (official; post-purchase) two-month point before I clean/document the accumulation. Current (aggregate) temps are symbolic of the heating dynamic, and the MS never breaches 36C
I work outside, so I introduce a lot of "stuff" into my environment. I am also owned by two quats, so there is a lot of fluff circulating in the house. I've tossed USD50 into proverbial rubbish for many an other wildly-crazy proposition.
Additional layers of protection may not always be pleasant, but they never *cough* hurt
Finally got to it (iStat temps were showing mid2upper 40's).
Nothing really there for a photo; maybe just two pinches of cat hair, total.
I powered-down for the cleaning.
Temps are now in the mid 30's . . . -10C prob. due to other factors, rather than the removal of 1cm^3 of cat hair
