Ok so i got a few case fans to see if my temps would drop by much. Unfortunately, they didn't and i have pinned the culprit on my case. Im looking for one in the £35-£45 region that has good airflow and enough room for some upgrading. I dont mind if it doesn't come with case fines, but its always a bonus 
I have liked the look of Lian Li's or the Antec P series. Also i dont mind if its second hand, but i relatively good condition of course.
Also I dont need a PSU with it either as i already have one.
Thanks for any advice.
