Help! Cooling down the power supply


I’m having issues with my power supplies. While the mining rigs are at decent temperatures (60 to 70 degrees on average), the 10-pin power supplies attached to them get extremely hot very quickly. After one hour, I can barely touch them for more than two seconds without burning myself.

Not sure if this is normal, or I should be looking at a different power supply? Is this something I should be worried about?

Thanks in advance!
