Had that too, did indeed have to enlarge the picture to see it clearly.You're right on the DIMM slots. Looking at the picture before it looked like they were in the 1st and 3rd slots, so my bad on that one. I should have enlarged the image.
Was thinking of this with those 5 fans. Wonder if the fan that is in the case right now can be freed up if he gives it a good clean, also should check if it is connected. Whole thing for that matter should be cleaned thouroughly.admittedly case can take 3 x 120mm in front so that would work too. 3 intake, 2 exhaust
