Alright, for anyone else having a problem with their V8 cooler not being seated properly, I HAVE THE SOLUTION!
NOTE: This is only tested with an Intel CPU on the socket LGA 1366. It may or may not work with AMD CPUs and their sockets, as the V8 cooler uses a slightly different bracket for them.
First, with the stuff that iBuyPower sent you (like the manuals, cables, CDs, etc.), look for the bag with the 'extra' stuff for the V8 cooler as well as the V8 manual (as it can help if you don't understand what I'm saying). Take out the hex nut adapter which helps you screw/unscrew the nuts for the cooler as well as the 4 small round pads that have one end that's sticky. Also, if they gave you some, get your nice thermal grease tube ready to go. If you don't have any of this, call iBuyPower and they'll send it to you for free (they did it for me, even though I found I had the stuff AFTER I asked them to send me replacements).
Next, make sure both sides of your PC case are open and off after you turn off the power and unplug everything. Disconnect the power cord for the cooler from the motherboard. This may or may not be tricky to get to. Then, on the back of the motherboard, unscrew the 4 nuts from their screws that's holding the V8 cooler in place. You'll have to use the adapter to do so. If one is stuck (like mine was), take a small wrench and carefully (VERY CAREFULLY!) grab hold of the top of the screw inside the case. This is VERY difficult to do because the screws have flat round tops with really nothing to grab. But I have first-hand experience in getting it done nevertheless, so I know it's possible.
Once all nuts are off, you can take off the back bracket as well as the V8 cooler out. Obviously be careful here as to not damage the motherboard or any other components in your case. Flip the cooler upside down so you can see the bottom. First off, clear off the thermal paste from it as well as the CPU, as we'll put new paste on later. Look at each of the 4 screws and make sure they are pushed farthest away from the cooler. To move them, with the cooler still upside down, you can push down on them and then slide them in the direction they need to go. They somewhat illustrate this in the V8 manual as well. Also make sure the screws are fully put down in their slots so they CANNOT turn. Otherwise you'll have a hell of a time getting the nuts back on all of the way as the screws will end up turning with the nuts.
Then gently smooth a thin layer of thermal paste onto the V8 cooler as well as the CPU. Next, take those 4 little rubber pads, reveal the sticky part by removing the tape, and stick them to the 4 nuts that you just unscrewed. Then you may gently place the cooler back into the case on the CPU and make sure all the screws go through the proper holes in the motherboard and pop out the back side. From her on out, you may need someone else to help steady the bracket as you place it back on and try to screw the nuts back on. This is also where it gets VERY TRICKY! Because while holding the cooler in place, you're going to have to screw the nuts back on, rubber pad side facing the motherboard. Since the pads are on, they make it more difficult to screw the nuts back on and as thus, you may have to push on the screws from the other side to give you some leeway. I started with 2 screws diagonal from each other, and then continued on the other 2. A couple took a decent amount of pressure on the screw from the other side so I could get the nuts screwed in all the way.
Slowly screw the nuts with pads back on, going diagonally first (as the V8 manually states). The pads are going to twist and bunch up a bit, but they still provide the extra layer which forces the V8 cooler to be pressed firmly on the CPU, which is our main goal. This is kind if like using regular metal washers, but unfortunately I didn't have any small enough, and I'm trying to make this guide with what's available to you. After that is all done, double check to make sure the nuts are full screwed on. They should keep going until they stop, which is about when the screw is fully flush with the nut. Also inspect everything else to make sure the cooler is nice and snug and whatnot.
After that, just plug the power cord back into the motherboard for the cooler, plug everything else back in, and start it up. A good way to test to see if it worked is to use a program like CoreTemp or HWMonitor to monitor the temps while you do some stress testing with Prime95. I got my full load temps from 100C down to barely 60C! And I haven't even begun to overclock yet.
So, there you have it, a simple enough guide to fix the V8 cooler seating problem. If you have any questions or anything or don't understand some things I said, let me know and I'll try to help. I hope this helps some of those with the same issue as me so they don't have to send their system back or anything like that. Enjoy! :-D
