What kind of oil did you use for your miner?
The only oil that I know can be used for cooling ASIC miner is mineral Oil if you use different miner that has little resistance it may affect or damage your miner.
first, why these t2t look like t3 and have power beside them ?
they have 35 th not 50.
That's strange if your t2t PSU is on the side and the actual hashrate of t2t is around 30th so don't expect more hashrate.
If it is t3 the hashrate must be around 45th.
Better check the unit model on the side of the miner you should see it with serial #.
About the increased temp then die it might because of the oil and maybe the fan is detected as not running or not reaching the minimum RPM speed.
Much better check the logs in WebGUI to find the issue or copy them and paste it here(Use insert code function before you paste it).
