Miner doesn't respect temperature limits (Linux)

[g1sbi]

Description of the bug
I'm on Pop-OS 21.10 with an Nvidia GPU and I use the 'sudo nvidia-smi -gtt 65' command to set a temperature limit. It works perfectly in games. However, it doesn't in the miner.

Steps to reproduce

1. open terminal and enter 'sudo nvidia-smi -gtt 65'
2. test with a game to make sure the command went through
3. open miner
4. watch temperature rise above 65 C

Expected behavior
The miner shouldn't push the GPU above 65 C and keep working as expected

Environment (please complete the following information):

• Operating System: Pop-OS 21.10
• Hardware: Nvidia RTX 2060 Super
• Ethminer Version 0.18
• Ethminer options used: none
