Does The R5 ii Fan Grip make 4K SRAW recording infinite?

Hi there I'm Looking for real-world results on the EOS R5 Mark II, on how fast it Overheats in the RAW modes with the Fan grip. Unfortunately i did not find any tests that test the RAW 4K runtime with the fangrip.

So does anyone have a runtime until overheating for:

• the CF-R20EP Fan Grip and Auto Power Off Temp set to High, ib 4K50p S-RAW (Light) ~700 Mbps?

Without a Fan Grip i got 23 Minutes
