DL380G5 Power Supplies running extremely hot

I have 3 DL380G5 Servers in a rack and they are generating so much heat in the rear near the power supplies that they are almost melting the power cords. What can cause this?

Also, is there any kind of fan or cooling device that can be used in the rear of the rack to help cool the systems?

The power supplies for these servers have a tendency to brake down. Can you try to replace it with another one?

Spare part number is 403781-001

Is the server room cool enough?
The difference between ordinary and extraordinary, is that little extra.

How hot is your room is the question. I know generally depening on what processors you are running the Power supplies can run quite hot... I have seen them run quite cool with a lower clock xeon the higher clock ones i have seen them get quite toasty. If you think about how a power supply works if it is getting hot then your using quite a bit of juice and it's working efficently.

We are going to try the overhead fan kit for the rack and thicker guage power cables and see if this helps the situation, so far none of the power supplies have failed.
