Cooling a computer in enclosed space

[siml12929]

Just had a new wardrobe with an enclosure for my computer.
The computer is running very hot, with case temps getting to : 31C and GPU temps: 82C
The area around the computer seems very warm, and the surface of the case is warm to touch.]
I am currently using a desk fan to try and circulate the air. How can i cool it better?
1 intake on front, 1 intake on left side, exhaust on top and rear.

How is the cable management inside the case?

Quite good, gets nice temps when not in cupboard. (however, must have in cupboard now)

You may want to get some SP (static pressure) fans, as they handle restricted airflow situations much better than AF (air flow) fans. What is your CPU cooler, and make sure that you have the fans on full speed.
