I have an Asus gtx 750ti which has an amazing cooler and at max load I only get around 60 to 63 degrees Celsius, but I have been tinkering with overclocking with it. On msi afterburner I upped the voltage but I assume this won't do anything because its not higher than the max voltage the card can support. Also I tried to overclocking before and got an unstable one but the temps were normal so no damage was done. Anyway is maxing out the voltage bad and I overclocked around 150 extra megahertz on the core and 300 on the memory added with the extra factory OC on the card.
