980 TI Hybrid thermals

[Thevgk]

First post here, be gentle.

I've had my 980ti hybrid for a few weeks now, and just recently upgraded to a new G21 from Thermaltake, great case.

Issue is, when i installed my card and ran my synthetics i was getting peaks of 72C. While this isn't terrible for a standard cooler, this AIO never got above 50C at max load over long periods of time in my previous case. Now taking into account the fact that this case has tempered glass side panels, i took off the side panels to let more air in and repeated my synthetics, and saw it drop to roughly 66C at max load, so airflow definitely helped, but that's still roughly 16C higher than my previous case, that seems like a bit of an issue.

 

The fan is putting out tons of hot air and is at 100% speed so it's doing it's job. I've read a few places about how air bubbles can affect performance when the card is moved around, but i don't have much experience with AIO coolers, any ideas as to why it's not keeping at that brisk 50C?

 

PS: It is overclocked by 150 mhz core speed, but that hasn't changed from the previous install.
