13 years ago, and if it was an office type computer the GPU, if it came with one, would have been 35W or so and 256mb-512mb of RAM. So cooling wasn't an issue. If you have an empty expansion slot you can add a blower to pull air out there. Antec Cyclone is one. Some times expansion slots have solid blanking plates that can be replaced with vented ones. Sometimes the air can get in but has no way out. Once the air has a path to get past the GPU, look at the power rating of the fan Watts. You may be able too find a more powerful fan in the same size. If there's room a thicker fan will be better. Most MB can handle up to about 1 Amp. Be sure it's an ATX layout computer. 13 years ago BTX was a thing and MB/case swaps are just about...
