Do I need extra fans?

can't ever hurt.

If you are not having temperature issues then there is no need. The 465 is a hot and power hungry card so you should check the temps under load to be sure you wont have problems.

If you ever add a second GPU you want to budget for at least one front and the side fan.

Run your build and put it under load

If you are getting high temperatures, then buy some fans...

You probably won't need them, but if you have problems, they might help.

I'm of the view that more fans generally lowers temps and make the cpu work better. a CPU that's only 50C at load will be less stressed and last longer than one thats 60C at load

Get an after-market CPU cooler, get a good fan on your side vent, in the back, and in front thats pretty much all you'll need and if you want to get extra creative and if you have space go 1 on top.

Ah. If I were to buy only one more fan (right now the case comes with the fans for the top and the back) would it be better to put it on the side or the front?

I won't be adding another gpu any time soon.

Running the gpu under a load it goes up to 70 C max i've seen.

CPU i'm not sure how to test the temp for that without extra tools. Or is there a built in themometer on the mobo maybe?

I have the MSI H55-G43

Thanks for the quick replies! =]

Ah. Got it. Thanks everyone! =]
