I have an ATI 9600XT card in a spare system that I'm reserving for LAN gaming (bought a small case with a handle). Problem is that the fan on the heatsink is very noisy. My solution so far has been to disconnect the fan, which unsuprisingly solves the noise! I got the card new for only £20 about a yr ago and I don't want to have to spend as much again on aftermarket cooling! However, this card doesn't have any temp monitoring on the pcb so I can't directly monitor the effect of not having the fan. Fortunately my case has an LCD with a single temp probe, which I've stuffed inbetween the fins of the card's heatsink (towards the top of the heatsink - the card stands vertically in a horizontally mounted motherboard). When I run atitool's spinning cube the temp probe reports ~50C and I don't get any artifacts etc so all seems OK. But I was wondering if anyone knows the likely difference between the heatsink temp and the actual chip temp and also the usual operating temp for these cards? I'm thinking that maybe these cards never really needed a fan and a fan was just added in case of use in hot environments, poor case airflow and under exreme circumstances etc What do you reckon?
