the story continues, has been some time now since i was in contat with the support department so they have had time to "forget me" so last night i dropped a mail to the sales department complaining about the loud fan and mentioned the age of the card.
also mentioned i have changed fan several times before with good results and that i have the tools knowledge and education to change the heatsink and this time i got an answer saying it is ok to change the cooler without voiding the warranty.
quite the opposite to what they said the last time, is it something i have learned is to ask a second time if the first answer isnt good.
not the first time this happens to me
so tonight i will check some reviews and read up on the coolers i can easily get.
get less than 2 celsius difference in both cpu and gpu with the normal cooling and with the side of and a table fan blowing in so its not a big problem but will think off it.
thermalright v-1 it will not be, costs 45-50£ or over 3 times what the nv5 costs.
im a bit cautious to the zalman vf900, it does not cool the memories and dont want to glue on memory heatsinks so looks like it will be the nv5.
but will check around alittle if i can stay awake today.
