Well, there are several steps you can take to optimize your mining setup. Firstly ensure that your immersion solution has enough heat exchanger tubes for maximum cooling efficiency. Secondly make sure that CPU fans installed by default on the equipment aren't blocked, allowing the fans to better cool down devices. Thirdly re-work SATA cabling slightly in order to position disk drives further from inside of rig near hot Radeon Cards and Air cooled internal PSUs - this approach will allow more free space for better/radiator cold air intake thereby increasing air flow speeds over equipment hotter items (cards ). Finally go ahead and paint around thumbscrews with nail polish or any fast drying enamel so as to help minimize the actual temperatures at locking points- which helps, somewhat!
