Hi folks

Got this case last month and I have to say it's soo sexy!!

I had a CM Stacker 832 which was nice, but i ran into problems fitting a 3rd GTX for Phsyx. (The dual slot was hitting the bottom of the case)

It was this reason I decided on the Corsair.

It's massive inside!!! But I have a question about air cooling.. (Not going water YET)

The CM Stacker was a great case for air cooling, and since changing to the Corasir, temps have increased by an average of 8c. (Nothing serious to be honest)

But I would like to optimise for air. At the moment I have the stock 140mm fans, a 120mm fan in the lower HDD bay and 3 x 120mm fans on top as exhaust.

The CPU cooler is the push and pull Noctua system, which I have directed to blow the air straight to the rear exhaust fan. I seen others have it facing upward to the top exhausts, would that be better for CPU temps? (Thus changing the rear exhaust to blowing air INTO the caes?

A few previous posters have this Noctua system in the pics above.

Thanks in advance

Val

hey guys whats the RPM for the 140mm fans we have in our case?
post #183 of 8657
It's showing on my fan reader as 900rpm. That sounds about right to me.

Add me to the club. Got my Corsair Obsidian 800D today from MNiceGuy (Thanks!).

Its huge. I imagined it to be pretty big, but Ive never owned a full ATX case before. My CM690 is tiny compared to this thing. It's awesome.
















Unfortunately this thing is still not up and running. Waiting for my Corsair RAM to get back from Newegg RMA. First kit came with damaged contacts. Also need to get a 8 pin EPS power extension because my cable doesnt reach behind the motherboard.

I should also be getting a Corsair HX1000 sometime this week.

I just finished rejigging my rig last night to improve temps. They have dropped my 6c on average.

If you look at Shiarua's CPU cooler above, that was like my own cooler. What I done was to change the cooler around so that it points upward to the top fan exhausts.


Then I reversed the rear fan to act as an intake. So it now blows air directly onto the CPU heatsink.

The final change was to remove the bottom cover of the lower HDD rack. (The one with the optional 120mm fan and 2 x HDD spaces)

As I have a fan in there, with the bottom compartment removed, that fan is keeping the lower 140mm fan well supplied with air.

I will post some pics later.

1. What is the biggest rad i can fit in the bottom if i remove the hard drive bay down there and still have a long psu (like a 1000HX). I think it is dual, but just need someone to verify.
2. Is the front i/o cover made of 100% aluminium?
3. Can the drives in the 5.25" bays be slid back and forth to adjust how far forward they stick out?

Thanks!
1) A dual 120mm fan radiator.

2)The I/O cover door along with all the 5.25in bay covers are all made of plastic. the actual I/O device is made out of steel, The large front piece and the door for the hot swap bay is aluminum.

3)There are screw holes that could be used but the tooless pieces have to be removed.
