How's it going guys, just found this thread after a quick google search and decided to join the forum.
I just received my Crosshair IV on Friday, June 4 2010, for my new system I have been anxious to build. (Finally upgrading from my trusty old Asus A8n-SLI Premium)
I spent Saturday building my new beast after all of the components finally came in. I ordered from Newegg about a week ago and had noticed a few people had mentioned NB temperature issues. Surely they must be fixed by now right? Wrong.
Start-up time! Windows 7 here I come. Diagnostic LED's, passed! Voltage Led's, great. Upon initial boot up, I started navigating around bios and immediately brought up the hardware monitor to see where I stood. Everything is looking good, CPU ect, and then I see it.
North Bridge temp = 70*C and rising. I watched as literally within 30 seconds from first boot-up, temperatures climbed... 75C....80C (Red Zone)....84C+.... All while idling in bios.
I shut it down before the motherboard could shut itself off. I booted two more times later in the night, netting the same result. Couldn't even make it stable enough for OS installation or Bios update. Voltage was right on the mark, and it was blatantly obvious the heat sink issue had struck me. Needless to say, I'm not very happy at the moment. (This was in a camo NZXT Evo case with all 120mm fans replaced with 90cfm units and impeccable wire management by the way.)
Already filed for an RMA and am most likely going to overnight it tomorrow to expedite the process, but the fact that the replacement might have the exact same problem is really bugging me. A close friend of mine just purchased an Asus 89gx Pro with a similar setup and his board has been perfect. Its such a shame because the features, design, OC options, and everything else is just perfect on the Crosshair. I can't help but feel that if I would have been cheap and bought the other board, I would actually have a functional system right now. :-(
I have always used Asus and they have never let me down before now.
Praying my 2nd board won't be a dud.
