I have a Cargraphic cooler in my 964 for the hot days at the track and it makes a big difference. In my 993, I installed a switch to allow me to run the oil cooler fan at high speed and it makes a big difference in stop and go traffic. You can also check to ensure your fan is operating properly at low and high speeds. For street use an extra cooler will not help much, especially in traffic.
