Hi guys my pc is getting warm , ive got an i7 3770k which is not OC , ive got Kingston HyperX Blu 16GB ,Gigabyte Z77X-UD3H Intel Z77 , ZALMAN CNPS20 LQ cooler and all in an Corsair Obsidian 550D case , now if i leave the side on after a while i check it and its warm in there , is there any way i can cool it down more , all the fans are sucking / blowing the right way , in front out rear , is it worth me swapping to a normal heatsink and fan ? any suggestions , needs to fit in the case , it needs to be quiet but cool . many thanks in advance
