why replace something that isnt broken ?

99-105C in certain heavey games....
Part of our task of troubleshooting/problem solving is to understand when something that doesn't look broken is going to croak sooner than later. The card that you've linked in the picture, if it is at all what you're working with, was designed for small form factor builds, akin to Dell OptiPlex uSFF/SFF units meant for day traders or CNC milling machines or CAD environments or in environments where display output is needed with minimal fuss on maintenance(power, cooling and limited chassis space), which explains why the cooler on that card is pretty much non existent, not to mention that the card is a half height design.
A card meant for gaming would have a larger/beefier heatsink and supplemental power delivery. Your card's support also expired on the drivers front in spite of tech moving forward and pretty much all apps/games demanding more resources. With that, your GPU hasn't seen any change in the last 7 years.
If anything, place a band aid on the GPU, coax it home until you can save up the funds and then invest in a GPU as opposed to strapping a bigger heatsink and offsetting the fact that the GPU chip is being stressed beyond its intended usage scenario. Speaking of, GPU prices on AMD's camp are pretty much (very close to)MSRP now.
Final thoughts?
You forgot to mention the specs to your build + it's very likely that your case is devoid of optimal airflow or the innards need a deep cleaning session + a reapplication of thermal paste.
If you wish to add specs to your build, please list them like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
FYI, back in the day, you would know a GPU is geared towards a workstation only environment when you noticed DP (or miniDP)connectors on the rear I/O as the only source of display output. That was a time when DP was available on premium pedigree monitors and/or GPU's.
