I have a MBP and it has been somewhat hot lately and I decided to download a fan manager for it. I got one (http://macupdate.com/info.php/id/23137) and it worked like a charm, but I would like to know the fan's top speed. The top speed is set to 6000 (I can't change it) and my speed is well below that. Would you consider it safe to use? I found some info on the fans (www.delta.com.tw/product/cp/dcfans/download/pdf/BFB/BFB45x45x10mm.pdf) here. Thanks in advance!
