Exhaust hood fan?

[Bad Wolf]

Now that the heating season is almost over (still need it for hot water) I have some improvments to make. I built a hood to suck out the smoke when reloading the furnace last fall and have a 4" vent pipe going out the side of the house with a small inline fan. Works fairly well but if I get hot smoke the plastic fan blades start to soften and it hits the side of the pipe.

Does anyone know of a fan that will stand up to higher temps?

Thanks

Even the fans I've seen with metal blades say max temp of 104 f, but yes they would probably stand up better.
