THERE'S your weakest link: the single fan heatsink's thermal capacity is low.Yep it is
I have a Zalman S5 with 1 120mm in the front and 120mm in the back, is that good or should I maybe add one or two more fans in the front? If yes which do you recommend, that are cheap and good?Hitting those temps would be more normal for fanless mode and watching YouTube.
There's a big difference between safe temps and acceptable temps. For me, 50-55°C at 100% fan is not acceptable for that workload. Even though it's well into safe.
As @hotaru.hino pounted out, that could be nothing more than bad case airflow keeping your gpu in a Hotspot and not supplying it with plenty of intake air.
What case do you have? Airflow largely depends on what case you have.I have a Zalman S5 with 1 120mm in the front and 120mm in the back, is that good or should I maybe add one or two more fans in the front? If yes which do you recommend, that are cheap and good?
Yep it isZalman S5...
Is this one of those single fan 1650 Supers?
I think that my case has good airflowWhat case do you have? Airflow largely depends on what case you have.

How to do that?THERE'S your weakest link: the single fan heatsink's thermal capacity is low.
They are a lot like the boxed Intel stock coolers.
You won't be able to significantly improve thermals on the card because of that part...
Actually, I take that back. An undervolt might help a little - reducing both power and voltage use instead of letting the card draw as much as it wants all willy-nilly, thus increasing the soak time for the little heatsink.
Quick/short version:How to do that?
Dont worry I just undervolted it to 1900mhz at 850mvTHERE'S your weakest link: the single fan heatsink's thermal capacity is low.
