As you can see from the date of my first post here, it's way far now from the Warranty option.
Ok, so the size and the 12V parameters are the only that I must be aware of? Suggested minimum CFM maybe?
I will look after some similar in some local PC shops here as this linked seems rather be a bit pricey (for a tiny 3.5cm fan + delivery cost). Tho' the ones I've looked up so far are totally lack of 3.5cm fans (and have rather a bunch of 4cm ones). But will try Conrad or similar and hope to find a right one for at least half of that prize, but the postage still will cost more on it's own than this tiny little thing would worth anyway...
Thanks!
