That is awesome that the 200mm is doing the job. Makes you wonder if Corsair will be releasing 200mm fans in the future.

I restarted and everything was fine again except that it now makes that annoying clicking sound. I really don't want to do the whole RMA deal. Plus I got it from Corsair for half-off during their holiday sale last December. I'm trying to sell this thing and I'm thinking that clicking noise might turn off potential buyers frown.gif

Have you fixed it yet on your end or did you RMA it?

That stinks. I keep reading little issues here and there with the H100i, that is disappointing to hear.

From looking at the pictures in this thread it would seem that the bulk of you (who have 240 radiators) are using your fans to pull air from the outside. Is this accurate or are you guys pushing air out? Would it not be better to push air from the outside in?

I am almost ready to get this case but I am still waiting on more shops online to carry them. Oh, and you know, the whole looming Z97 thing...

On mine, I have the air being pulled from the outside. I wanted to go with fresh air coming through to the rad. I have also seen many other setups where the fans are on the inside pulling air in from the case. I like having positive air pressure for dust purposes, plus in this case it would seem best to go this route but others might have different opinions on setup.

ive got on mine pushing air from front inside, it's plainly because of h100i, fans on it are also pushing air inside and the air that goes thru it winds on gpu, by having intake fan on front this air is getting pushed outside torough the air conditioning mesh on the rear of case.

Okay, I officially love this thread.

I did quite a bit of testing regarding the fans, here were my personal feelings and thoughts.

Setup:
Right side: 2 x SP120 PWM Performance @1000 approx rpm
Front side: 1 x AF140 Quiet @850 approx rpm
Left side: GFX Card: 1 x MSI GTX770 TF 2Gb OC

Config1
Right side: Exhaust
Front side: Exhaust
Left Side: Intake via the GFX card fans.

Due to the negative pressure, I was getting really nice temps from the GPU due to the increased flow of air passing it, in intensive games the CPU temps went higher than normal due to more warmer air in the case. I do not have exact temps for you for this one, after little sleep in the last 3 days I just wanted to get something working nicely smile.gif

Config2
Right side: Intake
Front side: Intake
Left Side: Intake via the GFX card fans.

Due to the extreme positive pressure, the Left side was actually being an exhaust and felt like it was fighting with the GFX card fans, basically my temps for my gfx card while playing EQLandmark reached a peak of 92c and was under-clocking itself , on the stock fan profile the fans never got enough RPM at 48% speed to actually start drawing air in. I did not like this config at all.

Config3
Right side: Intake
Front side: Exhaust
Left Side: Intake via the GFX card fans.

This one worked better for me, there is still a positive pressure in the case but not so much that the Left side becomes an exhaust and over powers the gfx card fans at stock RPMs, the gfx card gets to around 78c under 99% usage without any noticeable under-clocking.

Update:

Config3 Version 2
Right side: Intake
Front side: Exhaust (Removed the dust filter)
Left Side: Intake via the GFX card fans.

Slight modification to Config 3, just tested it, I was running the GPU program Heaven Benchmark 4.0, with the dust filter the GPU temp was 80c, after removing the filter and replacing the front panel the temps slowly dropped to 64c. Also motherboard temps dropped from 50c to 40c, also a few c lower on the cpu. As it is an exhaust I think it is fine without the filter... should have removed it earlier but did not think about it...

What did others experience?

The widest part of the fans are wider than the mounting holes, so there is less room there than you would think. I think most 200mm fans are designed more to move air quietly than move more air volume? I wish it did fit, because I really love big fans.

I beg to differ , i have my corsair H100 and the bitfenix 200 spectre pro installed together and there're no issues at all .
i think most round framed 200mm fans won't be a problem whereas the rectangle framed ones probably would interfere with installing the 240 Rad

That will effectively tighten the pump when screwed down (pump won't move), but won't allow full clamping force to the CPU. That can cause higher than normal temps or/and a widely varied temp among cores.
It should look like this:

That will allow full clamping force. This does not affect all motherboards, but it does affect some include the Impact.

So which is the correct position here the top picture or the bottom picture cause I have this same issue when I installed mine on a Asus Z87I.

It should look like the bottom picture.

Its kinda hard to get pics of that area now but I've got this one from when I started, the loop runs from Res down to Pump, 120 Rad, CPU, GPU, 240 Rad, Res.

this pic is from before I added the GPU into the loop
