Hi there!

I have a GTX 960 SC (ITX) and am thinking about removing the plastic shroud of the card because I have a 140mm fan directly below the card (less than 5mm distance).

The aim is to keep the card cooler before the 90mm fan kicks in at 60°C. At the moment the card does not seem to be affected by my case fan because it is protected by the plastic shroud.

Can I remove the plastic but leave the 90mm fan in place?

Any thougths?

So, I removed the shroud and the idle temp dropped from 35-36°C to 29-30°C. So well worth it!

The load temp with Heaven 4.0 went from 75°C to 76°C. Not a huge change.

The case fan is a Noctua 140mm fan and roughly 3-4mm away from the GPU heat sink. So it can really work efficiently I think. It is in the bottom of an NCASE M1.

But, I am disapointed with the fact that under load situations I do not have an advantage here. That is because the case fan does not ramp up with the GPU temperature, but with the CPU temp.

Can I somehow power the Noctual 3-pin DC controlled fan with the GPU fan header? That way the case fan revs up when required.

You could control the fan with Speedfan software. It is not easy to setup but not that complicated once you read a few guides.
Using Speedfan I control my fans that are plugged into motherboard. Fan speed changes depending on the GPU temp.
I think that this was the guide I initially used - http://www.silentpcreview.com/SpeedFan

Thanks! I tried SpeedFan yesterday and it did not seem to detect any of the motherboard fan speeds. It wasn't showing any data from my board...

I tried installing Asus Suite 3 and FanXpert but couldn't do it. I messaged Asus support about this.

Is there a solution to connect the fan directly to the GPU? The plug seems to be smaller...

Edit: I saw that the BETA version of SpeedFan should work. I will try that later this evening! Nevertheless a hardware solution (connecting to the GPU fan header) would be great because I will be running Windows and OS X on this system.

Yes, there is a cable that connects regular fans to the mini 4 pin on the gpu.
Here is a link to an example - http://www.amazon.com/Gelid-CA-PWM-02-Adapter-Sleeved-Cooler/dp/B005ZKZEQA

Great, thanks!

But then the EVGA fan would be turned off. Is there a splitter for the VGA fan header? Then I could still power both fans...

OR a male 4-Pin PWC back to female VGA 4-pin. Because I have a normal 4-pin splitter...

Btw, any idea if the VGA fan is PWM? Because my case fan is DC controlled.

Edit: Found a splitter! http://www.performance-pcs.com/4-pin-vga-pwm-mini-connector-to-dual-ph-mini-4-pin-fan-cable-splitter.html
Just need it in Germany now :-(

Ok - I got SpeedFan Beta working. I will try to control the Noctua case fan with Speed fan linked to the GPU temperature. Would be great not to need to do any hardware modification.
