My opinion is that you can't always trust stock cooling devices to be adequate. 100C is nuts. But does the temperature look normal when the system is idle or first starts up? It could just be a bad reading...

I have a passively cooled GeForce 210 which I don't think ever got above 75C. And they are both 40nm parts with similar die size, so it would be unexpected if a 610 had overheating problems.

You need airflow for a passive GPU. They are meant to sit inside a case, mostly cheap OEM systems that are designed around that fact (sometimes with ducts).

In the desktop the gpu remains at 50C and the heatsink is burning so it's not a contact problem. Is it right the max freq of the gpu read in games 810mhz?

That's just mean that you didn't run shaders heavy workload. I removed the fan on mine when the fan was faulty and crackling along. GPU-Z showed the temperature hitting 97C running NFS3 Hot Pursuit at 1024x768 with dgVoodoo2. That was in the winter with ambient temperature 60F. The fan aluminium heatsink combo looked cheap on my Geforce G210 and perhaps didn't do a good job at heat transfer without fan blowing. I didn't bother to replace the fan/heatsink, upgraded to GT730-GK208B as one showed up on-sale on amazon.com.

That's possible. IIRC the only stuff I ran on it was old DX7/8 games.
