There's a lot to unscrew and you'll have to de-rivet several parts of the case. Not that easy to take apart if you aren't experienced with the required tools.

Easily. It comes with a pair of brackets for either mounting a triple radiator or 3 120mm fans up top.

at least i will be able to change the fans then...

i will have this case tommorow, coolermaster will probably release a pure version (all black) day after that, lol.

i've read the two top fans exhaust the air out too quickly, would removing one of the fans make sense ?

thanks.

So I've got a brand new i7 920 D0 stepping with an GA-EX58-UD5 sitting in my Coolermaster ATCS 840. PSU in the bottom, standard fans/cooling with a Noctua NH-U12PSE, with the Noctua fans that came with it blowing directly towards the rear exhaust fan.

I have my vcore and vtt at 1.3, and my CPU temps shoot skyhigh, up to ~84 or so when I'm testing with OCCT.

I'm thinking that there's not enough air getting, since if I take the side off, the temperature plummet down to about 73-74 peak.

So what are my options, without spending a ton on getting a bunch of new fans? I've got one or two SFLEX E's I can use..

I'm thinking since there's barely a cm or two of clearance between the rear exhaust and the Noctua fan, I should take off the rear exhaust, and plunk it into the bottom as an intake?

I'm also thinking of flipping the top two fans, any success with that?

PS: The settings that generate these temps are:
19X Multi, 193 BCLK
QPI X36, Uncore x16, Memory at X8, so 1544, which my 6GB of OCZ Reaper 1866 should be able to handle fine.. timings set at 8-8-8-28 at 1T

CPU Vcore: 1.318, QPI/VTT: 1.315, CPU PLL: 1.3 (also tried 1.8, no difference), DRAM at 1.64 and rest at either 1.5V for PCIE and ICH I/O or 1.14 V QPI PLL, IOH Core and ICH Core.

Load Line Calibration enabled, All CPU functions Enabled except for Turbo and C3/C6/C7.

Also an ATI 5870 sitting in the case, but I haven't done any 3D stuff, so the heat it generates should be negligible.

Any help would be very appreciated as I've been tearing my hair out trying to get this stable, and it seems like it's OCCT stable, as long as I can stop it from getting above 80C!

Interesting. +1, looks like a neat way to expand exhaust options.

Looks like it has been sanded on the back lol. Wow that's one thing I hate about shipping, you're always going to have something scratched or broken =(

my eyes are kinda hurtin' reading through this monster thread... i ordered my ATCS 840 a few weeks back, along with a 1000w single-rail p/s to transplant my beastie into. my current mid-tower is looking kinda borg with half the cooling system bolted and velcro'd to the exterior for lack of space. i'll likely document the mods on bit-tech, but i wanted to post up here as an owner. dremel and drill time!

I talked to the guys over at Cooler Master Japan and they told me that over half of the 840 atcs are packaged with scratches and shipped from the factory to the resellers. So I wouldn't blame the shipping circumstances, but rather the carelessness of the people who assemble these cases.

Got the Silver version of this case a month ago. Love it. Pics coming. IMO, the Silver is SO much better looking than the Black.
