You've made it to the late game and you want to get your hands on that juicy Mk6 Cutteray but you've noticed you need Thermoelectric Coolers to craft it. Well worry not for it is actually very easy to obtain these.
Collecting them yourself will require venturing out into the Deep Desert, but they can also be purchased from Vendors, or from the Exchange.
Farm Them In the Deep Desert
Along with many other high-end crafting materials in Dune Awakening, Thermoelectric Coolers can be found in the Deep Desert.
Specifically, they can be found within the Row A Testing Stations & Wrecks as well as in the caves throughout the Deep Desert.
A good way to obtain them is just to do a route from one side of row A to the other, heading into every Testing Station, Cave or Wreck that you find along the way.
Deep Desert Caves
Note that you won't find Thermoelectric Coolers in all of the Deep Desert caves, but any with a chest should yield at least some. The Caves that involve hidden upper chambers and small groups of enemies will yield the most. These typically have an entrance as shown in the image below:
Once inside, you'll find a pillar that has been knocked over. Jump onto it and it will lead to another moisture-sealed door. Behind it there will be a medium chest that usually contains quite a few Thermoelectric Coolers.
Buy Them From A Vendor
If you don't want to venture out into the Deep Desert just yet, then head to the Crossroads Tradepost where Thermoelectric Coolers can be bought for 5,000 Solari a pop.
The merchant has 15 on-hand at once so it should be more than enough for your crafting needs, assuming you have the Solari available to purchase them.
