I have the same turbo setup on the GQ. I assume you have an after market gauge fitted to read those temps. I have Never seen my GQ at 115c even after sitting in a Bog Hole revving at 3000 for an hour trying to get charge into a pair of flat batteries so I could do a triple line pull winch out. My Fan was not functioning either and I rebuilt it after that trip. But 115 is at the high end of happy.
Bleed her out and see what happens, I do not think this is a problem with the Turbo, if there is a problem it's either in your cooling system or the engine. If the bleed works then at high idle you should not see over 100 while bleeding I would not expect?? Yet your description suggests you might see 115? Hope the bleed sorts it out mate. The TD should run fairly cool, the fan hub is not the be all and end all, it's just a treatment for an symptom. Hopefully the bleed sorts it for you mate. Either that or it will present with continuos bubbling that does not desist or reduce and then there is your answer.
Good luck with the bleed.
