More aboutgraphics card overheating
Is it passively cooled or does it come with a fan? The maximum operating temperature for GT 220 is 105 C which is around 221 F.
That should be fine, because 147F is about 64C. GPUs overheat when they go above 90C. So you should be fine, although if it's 147C, the system would shut down and it's really dangerous. Better replace it and get a new one (or fix it's cooler).
