The mosfets do have a thermal limit of 130c Pin 36. "Temperature Sense Reporting/Fault Flag. The voltage at this pin is defined by the equation: 8mV * (Temperature in Celsius of driver IC) + 0.6V. OUT/FLT This pin will be pulled up to 3.3 internally under the following conditions: over temperature, over current, preliminary over voltage condition or phase fault condition."
Running 6+ days, end plates removed and 10" box fan blowing thru- 302 GH/s avg on Humpool with temps T1- 60c T2- 38c . Highest chip temp- 57.5c. Using Server p/s @ 12.3v and 126w. Veteran Miner's latest power cable and TSwift's pay-to-play firmware @ 270G_L . No other mods.
Running 293gh/s 24hr avg, 125w at the wall. Running tswift 280L firmware. this has heatsinks on mosfets, has mx-4 thermal paste, arctic 1mm thick thermal pads. Has the plates off front and back. single 120mm fan usb blowing in. Hottest chip is 53c. clock is at 77500000. not sure if i just have a really good silicon here or what, but is killing it.
@piratanet123 try different versions and see which gives u the best hashrate. Different chips won't handle the same. Ie, won't handle the higher frequency or power as well.

Pinning comment, good stuff, thanks bud

Good deal, and good data. Thanks for sharing

At 125w I’m only getting 250hash, hottest chip 39c. I don’t know what’s wrong.

my ks0 non pro's are not doing nearly as well. running like 165ghs, 102watts, chips around 70-72c. have not modded internal
Mod the internals
the serpents best work!
