No problem, sounds like you have an air flow problem....
Get 2 8cm arctic cooling fans, one from the fonr sucking air in at the bottom and one blowing it out at the top of ur case at the back, and if u get a Silent Smart PWM cable for 2 PWM case fans and cooler, you can plug this into ur CPU fan socket and the reconnect ur CPU fan and 2 additional ones to this, so then, if ur CPU fan speeds up, so will the aux fans, keeping it all nice and quiet when ur system is cool.
I'd also reccommend an asaka pci system exhaust placed above your GFX card with the fan facing downwards to draw air away from the top side of ur card (but put it the opposite side as the GFX cards own fan else it wont get any air.
That should coll your system by at least 10 - 20 Celcius and should only come to about £13 at the most ($19 US).
