Had a gtx 1050ti and that was max. 72 degrees warm. It ran normally at 67 degrees. Now I have a gtx 1660 super and suddenly it is in warzone or fortnite 88 degrees warm fan on 100%.
What could be the reason. Can you set something?
It's logical. Compare the TDP.
Downclocking, improving airflow.
The GTX 1660 has a higher TDP. If the fans are not so good then you have a warmer card. 88 ° C is a bit warmer than I personally like, but below 90 ° C without problems.
The GTX 1050ti (4GB) is actually a relatively "cool" graphics card.
Up to approx. 65 ° C would be conceivable under full load, or almost normal. But 72 ° C is an unusually high temperature…
The GTX 1660 super (6GB) has a significantly higher TDP (125W), but also a correspondingly larger heat sink. This graphic should therefore not get particularly hot (max. ~ 70 ° C).

You seem to have certain problems with the airflow in the case. Otherwise both grakas would have stayed significantly cooler.
You only "whisk" the hot air inside the PC case without effectively removing it and introducing enough fresh air.
(Which CPU and which CPU cooler do you actually use?)
A tip from me:
Let a controllable PWM case fan blow directly into the suction area of the graphics card.
Either through a front fan or an additional fan in the side door, provided there's a ventilation opening.
Because the greater the temperature difference, the better the cooling effect.
And this (individual) fan should be adjusted via a fan curve. The GPU temperature should serve as a reference for this. And first of all, this case fan should supply fresh air before the Graka fans have to turn up.

In order to direct the blown air in a more targeted manner in the desired direction, you can try it with self-made "baffles".
For the sake of simplicity, I would start with cardboard and try it out a bit. If this works satisfactorily, you could also use sawn-up acrylic sheets (or similar).
88 ° C is a bit too much. There's something wrong with the airflow in your case.
