  1. Custom. Makes sense. Thanks!!!
  2. What platform does OCC use? It kind of feels like vB3, but the look is different.
  3. Reading your first two sentences, I was thinking now who would do that to innocent RAM? Then I got to your third sentence. Sane and normal hardly describes us overclockers, but the terms are close enough to prudent that I will simply agree.
  4. G.Skill has low profile RAM of all varieties. Their ECO line is a match to any Ripjaws line they make. All modern RAM with tall heatsinks is pure marketing glitz. Don't fall for it.
  5. On my case, the side panel fan is a Kaze Maru 2, a 140mm fan set to intake. The side window is 120x120mm, with 120mm fan mounting holes. But the KM2 has 120mm mounting holes, and its 140mm fan takes up the whole 120x120mm square window, where a 120mm would take up less than 78% of the window. Better use of the space. In the diagram I left the choice of intake or exhaust open because some gpu's blow hot air in all directions. With lower front and bottom intakes the system could afford a side exhaust with such gpu(s). In my own case I used a nibbler to eliminate the pillars from between the slots in the backplane. Now I have an open window there just as I have an open window up where the rear grill used to be. I believe that removing the rear grill is key to developing what I call a positive flow case. With such an open area it cannot really build up a high pressure. Is it effective? Once I did an experiment. I removed both top fans and left those grill-free spaces open. In the other spaces I either removed fans or left them turned off. The only fans running were a pair of YL D12SH-12's acting as push/pull on a Megahalems. Even with the top open it was able to hold up a Kleenex over the lower front fanspace. And here is a picture of the power of a heatsink and an open rear grill space: BTW -- this is a $40 case. I'm toying with putting a plastic separator between the lower section -- the gpu space -- and the upper section -- the cpu space. Hobby shops sell sheets of stiff styrene for model railroaders to build houses. The stuff works great for all sorts of things. The reason I am not concerned about older experiments where you say "sure, you cpu will get another 2c of cooling, but . . . " is that in the Intel world, since the LGA1366 there is nothing left on the motherboard that needs cooling. Lynnfield took the last of the hot chipset components and put it on-die. The mb components not only don't need the cooling anymore, they are in a position tp compromise the cpu cooling. And with an i7 8xx cpu, you really need to cool that. (And yes, I am aware that with each passing tick-tock, the need for even heavy-duty cpu cooling is passing.) That leaves the gpu, which is still very hot on gamers' machines and is(are) in a position to really mess up the cpu temps with not very much gain for gpu temps. Hence the thoughts about partitioning the plenum into gpu space and cpu space. It also explains why I think slot pillars have to go.

  8. Thanks! Learned two new things tonight. Excellent. Edit: though in Windows ctrl-W seems to do what it used to do: close the page or tab.
  9. And that is the difference: with the Z600R you mount it as you would a Mugen 2: you hold the heatsink in your hand and mash it up against the motherboard, then hold it while you fasten it from the backside of the mb. With the Mugen 2 you use screws. With the Z600R you use nuts. It worked well the first time I put it on. The second time was a biotch. Had to re-do it and the re-do was hard. The only way to do it reasonably easily is to take the mb out of the case, and mount the mb onto the heatsink. Thanks for the pic above. It explains everything.
  10. Great info on the Razer. Thanks for that.
  11. This is my rig, as of 2011-12-07: What's all that stuff doing? Here's a diagram: This is in a modded NZXT Beta Evo. It's not exactly the ideal case, y'know. So what would an ideal case be for air-cooled innards? This gets you a nice airflow into the cpu heatsink. you also get the top air blocking air from the gpu, so your gpu's heat does not warm up the cpu. Here's a standard setup, with a hint about why I do NOT like it: See how the top exhaust fan draws air up to warm up the cpu? I do NOT like this setup.

  13. Excellent question. Anyone got numbers?
