1) check it is plugged into the power first

2) Is there a fan in the power supply? If so then put the side back on. These things are designed to work that way. It may be that the case fan is not needed.

If the PSU fan works then download something like speed fan from here click here

to check the temps in the box. Look around the web to find what suitable temps are. If the ones reported in your machine are OK then don't worry. My case has three case fans and none work, they are not always necessary.

1.check fan is plugged into power ?
how do i know if its plugged in there a fan in the power supply
do these fans kick in when pc gets to hot

"how do i know if its plugged in" - the fan will have a wire connected to it, see if the other end is plugged in.

where do i plug the fan into

If it's a 4 pin molex connection click here , check out the power supply as it's probably got a free lead you can plug in to. If it's smaller than that it may be possible to connect to your MOBO if it has a suitable socket. Read the MOBO manual carefully before trying this approach.

Hi, if it is a case-fan situated on the side wall of the case it is probably not needed. I have such a fan on my case, but I disconnected its leads 'cos it was too noisy for my liking. My pc runs fine without that fan.

BTW taking off the side 'to keep it cool' has the opposite effect.
