I'm just suprised cause i was looking at the EK 680 directcu acetal/nickel waterblock at their site and saw this mini review of a customer: http://www.ekwb.com/shop/review/product/list/id/1188/category/41/
he states that his overclocking potential on the gpu core from offset 20mhz to offset 100mhz. if this is true, thats fantastic. what do you guys think? is there a benefit? has anybody else seen something like this when they watercooled their 680s?
He/she must live in a very hot place or have very bad airflow to be getting that sort of temp from a DCII.
If you find your MAX overclock at MAX fan speed and the GPU doesn't go over 70C then that is IMO as good as your going to get.
After 70C they start downclocking a little.
If you put it under water the only advantage would be even cooler running at same speeds and depending on your raditor setup, less noise.
I've not done water myself but this seems to be what people here say.
