temps would get hot... i had some high 5000rpm fan with a controller dictating the fan speed... but sometimes beyond 130F but those temp readers are still a mystery to me; some work, some read the wrong thing, this program sucks, that program sucks, ... what ever, all i know is raising the voltage and cpu frequency will increase the temps respectively in regards to ambient temps, the ladder being the most important. I have some type of temp reader instead of a thermostat, but both will do fine. if you air cool, don't forget you can never be below ambient temps, sorry if you already knew that... but to answer the question, the HS was a stock HS with a Thermal Take 3 fin 5000rpm fan...
