I managed to snag a silver case through Overclockers but haven't received a confirmation email yet.
Edit: just got the confirmation email. Back to bed for me.
Unfortunately no I didn't. I bought the C14 well before my M1 arrived and never even bothered with the fans that came with it since I had the GT's laying around. Would be interesting to do at some point though just for comparisons.
I actually do have another GT under there but haven't done any comparisons of temps before and after adding it. Here's a picture of the top:
I was able to snag my C14 for $40 shipped on Ebay. :D
Edit: forgot to add that I'm running a mild 4.2 OC and highest temp is 77 after a couple hours on...
Well, I heard some slight coil whine but it's nothing that would make me want to return it. I played 30 minutes of BF4 to test out the fan noise and I can honestly say that I can barely hear it over the other system fans. Here is a video.
Ugh, you guys are starting to worry me. Got mine a few days back but haven't had time to hook it up and test it out. I'll report back here as soon as I get around to it.
