I noticed quite a few people are using slot fans right next to the video card to cool their GPUs. Are most of you turning off the stock GPU fan and using the slot fan only, or do both the slot fan and the stock GPU fan run at the same time? I'm asking because I'm thinking about turning off (unplugging) the stock GPU fan on my x1650Pro and only using the slot fan for cooling. The stock fan is just way too loud for me. Would the slot fan provide enough cooling by itself?
