Sounds like your water circulation is a bit slow...have you checked the pump?
Only other thing I can think of is that the Thermaltake water cooler you bought may be a bargain model, in which case you might actually be better off with air cooling.
Actually, looking on newegg just now, it seems that your model is a small radiator, and relatively cheap. I would get a Cooler Master Hyper 212 EVO for $30 and you'll probably see better results. Entry level water coolers are often less effective than mid/high end air coolers. You really need to spend about $70-80 on a water cooling setup to get it to be more effective than the better air coolers.
I have the Water 2.0 Pro. it is the mid level cooler for that series. It has the same pump as the performance model but a double thick rad. The next step up would be the extreme that uses a double rad. I have an Arctic Freezer 7 Pro laying around some place. You think putting it on would be worth a shot?
Have you tried a push/pull configuration on your current water cooler? If not, buy 2 fans (the exact same kind) and put them on in a push/pull configuration. That would likely squeeze a bit more out of it.
Also, not familiar with Arctic Freezer 7. Though, if it has a bigger radiator, or more fans, it may be worth trying.
