The USB strip doesn’t stay balanced on the table and these fans are actually pretty noisy. These fans are connected to the Mars Lander. Looking back on this purchase I should have gone with the 3x compac a. However I have had problems with keeping the Mars lander hashing continuously. Spending a little $$ might have given me a bit more power but it would have also created a deeper regret when it’s not reliable. I thought about combining a larger 12x-15x usb strip with 3x compac f and 3x compac a and connect it to the mars lander but support couldn’t give me insight into this idea. When I asked what was the highest hash rate the mars lander could produce the support team member literally said “the maximum amount” without providing any more details.
