Those are dangerously high temps. Now, when you say shop, do you mean your own, "shop", or a shop in town? It sounds like there is no thermal compound. Obviously, the fan is running, because it is loud, unless that is a different fan in the system.
There is obviously a serious issue, here, ok we need more system specs, in fact all of them including GPU, mobo, RAM, PSU, PC case, also if you could take the side off your case and get a good picture of its contents this would also help us to determine a problem and recommend a solution, as it stands now it seems to me, that you should not trust your shop and that you should install an after market cooler with a good thermal paste on your own.
Is your motherboard qualified for the 955? I don't mean 'qualified' as on the cpu support list. Some motherboard OEMs place one or two 125w CPUs on their support lists but have limited actual voltage support.
If your vcore in the BIOS is set on *Auto* you should manually set your voltage. If the voltage remains high (above your manual settings) the motherboard is most likely struggling to power the CPU.
