GTX 970 Single Fan Blower VS Dual Fan Cooling in x51

Jump to solution

Hello! I have a EVGA GTX 970 FTW in my x51 R1, it has ACX2.0 that has two fans on it. Many users have been saying that the dual fan setup on the card blows heat around the system and the single blower fan pushes heat out the back of the system. I just wanted to get confirmation that this is true because I may be stuck with this card unless EVGA or Newegg will refund or trade out the card for a reference version. If it makes a slight difference then that'll be great news for me, but I'm running this at 65C idle, and 85C during intensive gaming or benchmarking on ultra w/ vsync off, also the card at 50% fan speed is LOUD (3000 RPM), like a jet engine. I'm wondering if anyone could report temps with their single fan blower GTX 970's and their experiences with idle and load fan noise.

65C idle is unexceptable.

Always go with the Blower Card / Reference Style.

Blowing 65-85°C directly onto the HDD?

A blast furnace of heat. It's simple physics.

You are going to ruin your machine, IMHO.

While you wait ...

Is there anything you can do to exhaust hot air from inside system or circulate it better?

What's your fan profile set to? I actually had auto off, I just set it to aggressive and nows it's running 2,150 rpm or 48% fan speed idle.. It's at 38C idle, Do you think my cards faulty? Also I could remove my optical drive to make a little bit of room to breathe and save a couple of watts -EDIT- It's maintaining 38C on the quiet fan curve running at 1330 RPM (30%), but it did take awhile to get down to that temp on aggressive. Your card really only goes up to 52C while gaming??

Also, I noticed your specs, do you have a R1 powerboard in your system? Did you modify anything to get your system from rebooting during games or did you just plug n' play?

Still experimenting with OC's & Profiles.

Fan profile points:

45 - 45%
55  - 60%
60  - 70%
75  - 80%

So I'm trying to undervolt in MSI afterburner and it's not working, so I found that some users remedy this problem from flashing the GPU's bios, theoretically could I flash a stock 970 bios onto my 970 FTW? or would that be bad? Also the FTW has 2 fans on it, so maybe if I did flash it, it would only regulate one fan?

Blower Card is your only hope.

X51 is a SFF which requires a reference style card.

Sell the ACX while you can... Admit the mistake and correct it.

970 Blower Cards are harder to find because they're the preferred choice for SLI, so people tend to buy 2 at a time much more often than dual fan models.

Ok, I ONLY have two options, get a blower 980 reference and upgrade to a R2 powerboard (170w limit) OR buy a mini ITX cooler master case (elite 130 www.newegg.com/.../Product.aspx) and a cooler master 550w PSU (CM V550 www.newegg.com/.../Product.aspx) I'm wondering if the dual fan GPU will work well in that mini ITX case, it has a lot of ventilation but I'm always worried that the dual fan gpu will blow the air in the wrong direction 😕 but which do you think is better? The first option is $220 + $40. and the second is $95 + $50

The extra 20 watts is mostly just the difference between SandyBridge 2600 [95w] and IvyBridge [77w].

IDK about Haswell.
