Still noisy...

Hi everyone,

I've just moved my system into a new case (Antec 1200) using all the fans it comes with set on lowest speed.

i7 920 2.67GHz running at 4.0GHz with a Noctua NH-U12P air cooler with both fans running.

I still think there's more noise than there should be, although a lot less than my old case.

Has anyone done a similar clock using that cooler with only 1 fan on the CPU cooler?

Haven't used that particular sink, but use the NHD-14 and NHC-14 fairly often, they both came with resistors to throttle the fan speed a bit to very quiet levels and temps don't suffer too badly, try those if you have it. Also, to be honest i'm very sensitive to noise and the Antec 900 never struck me as 'quiet' even with all fans on low.

So what's making the noise?

The stock case fans? The NH-U12P? Everything?

Is the noise worse at any particular location?

Slowing fans down is the simplest way to reduce noise. You can slow the Noctua down with the resistor cables. The Tri-cools are non adjustable below their too noisy in my opinion low setting. What I did was remove the Molex from my Tri-Cools and fitted a fan header and connected then to a fan controller. I also removed the fan and blocked up my top fan slot.

Is it these fans that come with that case?

I had two of them in my home server which btw also has an NH-U12P and those antec fans are actually pretty ****ing noisy even on the lowest speed setting where i think they are at 1200 RPM. I took them out and the whole rig was much quieter, replaced them with a couple of PWM fans that run around 500 RPM.

Unplug those antec fans then turn your rig on, see if it changes anything.

U could get a fan controller and swop all the 120mm fans for Skythe Gt's or if u don't want to add a fan controller then change them for something like the Akasa Apache Blacks, ur pretty much stuck with the top 200mm fan but on low mine used to be pretty quiet.
