Your opinion please on temps.
... I use a heat gun probe tool to measure the small back heat sink and it runs about 153F.  Knowing chips a bit 153F is OK.
... BUT the back heat sink runs about 162F.  I think this is pushing it no?  
Is 162F OK for the back heat sink?  What is the max temp on this to be careful of reaching?  Back in my old chip days 175F was about it before stuff starts losing a lot of life big time.

Back in the old days people read the instructions first Smiley -- see page 1 of this thread:

Even with a fan built in, you can still overheat your Moonlander at higher frequencies. I do not recommend running these past 800mhz unless you can closely monitor temps (if you have a IR temp gun check the top ASIC heatsink, it should not be any hotter than 80C).

Everyone using these beyond 800Mhz uses external cooling (fans). 162F = 72C which is getting borderline, 153F = 67C is really hot. I am running at around 35C = 95F.




My bad...  I missed this one line. And yes I have read page one many times.  I just missed the one single line on the temp subject.

"if you have a IR temp gun check the top ASIC heatsink, it should not be any hotter than 80C"

That is 176F and I am far below it at 153F.  To me this seems OK then?  Even at 832 clock and 163F this is still well below 176F.

So why do I need another fan?  I cannot go above 832 clock as I get too many hardware errors (over 10%) on these even cranking up the core voltage.
