+1 for these fans

92mm

80mm

Both are PWM fans so the noise factor is easily controlled- i ran both of full speed just to hear them and even then they were still very quiet.
Plenty of airflow now- the 80mm takes place where the 70mm ICE was, and fans are reversed.
Cables can be a bit messy due to the piggy back option that is offered, i have the 80mm PWM male plugged into the PWM female of the 92mm one so both fans are running off the one PWM header.
They are a slow fan so i don't think i'll overdraw the current provided by the header.

Thanks for sharing your experiences.

What range of RPM's (min -> max from the 92mm presumably) are being reported and which motherboard header did you connect them to?

900-1950rpm +/- 5% and connected to the header the 92mm one is normally on, next to the plastic ICE housing.

Thanks.

I assume you are using the BIOS to control all the system fans?

[daffy67]

BIOS control correct.

BIOS control correct.

These Arctic Cooling PWM fans are supposed to have a range of 600 min to 2000 max RPM , but on Shuttle XPC Motherboards I suspect the logic programmed into the I/C's that control the fans are specifically for the stock one supplied and installing another with different spec's often doesn't allow the minimum RPM's to be reached.

You are often able to get lower RPM's if using Speedfan or even Shuttle's xpc tools with replacement fans rather than the BIOS control settings, though I prefer to let the BIOS control them rather than another layer of software/complexity/problems, etc.

It's good to read that you are able to use these two off one header and which both have a 0.13A current draw. Was the original 92mm a Shuttle badged AD0912UX-A7BGL?

I considered these also but in the end went with Scythe Kama PWM fans that replace the ICE fan.  I liked these better because of lower noise and moving large amount of air. They are a direct replacement for the existing ICE Fans.
