The spec sheet on that drive lists 60c as the max operating temp. So yes I would say you have a problem. The good news is you can probably install a fan or two to get that number down.
As I said I can only get a intake on the side, and I am using my desk fan as that and it moves a good amount of air but it only brings the temps down a few degrees. there are no more fans I can get into the system. The only option I can see is to get a new case, which is what I'm going to do but that's not gonna be for a while.
BTW I have the Logisys CS-206 Case http://www.newegg.com/Product/Product.aspx?Item=N82E16811148044
(it has a place for a front intake fan but it's impossible to get one in because the UNMOVABLE drive cages are in the way.
