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?

How aggressive is your OC on the 770?

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

Any pics you'd be willing to share?

Have any of you changed the stock Corsair H100i fans to the Quiet PWM ones (120)? What is the difference in temp compared with the lower noise levels? No issues running the Quiet SP120 PWM whilst overclocking?

I am thinking of replacing the stock fans as they are slightly noisy even at 1000RPM so would appreciate opinions from people who have changed to quieter fans on this radiator.
TIA!

im thinking on getting them as h100i can be pretty loud at a times smile.gif

Yes those are the ones. I read up on "static pressure" but I can't find anywhere where the actual static pressure is compared with the stock Corsair fans on the H100i.
post #306 of 3052
H100i Stock Fans..
Static Pressure - 4mm/H20
Air Flow - 77 CFM

SP120 PWM Performance
Static Pressure - 3.1mm/H20
Air Flow - 62.74

SP120 PWM Quiet
Static Pressure - 1.29mm/H20
Air Flow - 37.85

I am using the SP120 PWM Peformance on my H100i and I can't hear them at idle. They can be noisy when I'm gaming and the fans speed up. Good trade off in my opinion, When I'm gaming I either have the sound turned up or I have my headset on so I can't hear them then either.

Thanks for that. When you say you cannot hear them at idle, what RPM are they running at?

Considering the size, shouldn't be a problem.

Nice work nonetheless. thumb.gif

I would like to know too, mine are running at 800 RPM and I defiantly hear them. same as the GTX 770 TF, it is on the Silent mode and I still hear it... perhaps my hearing is super sensitive.

Regarding a previous question, the GTX 770 was not running in OC mode, just standard game mode.

Anyone fit a Maximus VI Impact with a Alphacool NexXxoS ST30 Full Copper 240mm yet? I will be using 120mm x 25mm fans. I know I have heard it is a tight fit, but does it push against to riser board?
