hi guys i just saw this topic a while a go and started reading it from page 1...
i have some questions in my mind.. and the first one is do i need to buy 4 coolers for each board...? i saw someone saying its 25usd for each then it is 100bucks for all 4 just for one board...?
if it is a yes then this is gonna be a pricy one for converting my x3 order...
thank you very much..
Yes. Each chip needs to be cooled with a separate cooler so that's 4 chips and coolers per board.
