eVGA GTX 580 backplate, $20 for hotter temps?

post #1 of 43
Thread Starter 
Greetings everyone. Just received my GTX 580 backplate in the mail today.

First off, the backplate looks nice. Also, I guess it would do a good job of protecting the back of your card if you are prone to damaging the back of your cards?

Unfortunately, I was under the false assumption that this eVGA backplate was some sort of heatsink.
Under stock idle, OC idle, stock load, and OC load, the backplate made my temps exactly 1 degree hotter in each category, tested twice with the backplate on and off. I guess since it doesn't actually make contact with the transistors or chips on the back of the card, it just traps the warm air inside a little bit.

Conclusion:

Pros:
The backplate looks nice

More PCB support to keep it from flexing


Cons:
Paying $20 to make your card hotter by 1 Degree Celsius.

Pretty much just "bling" for your GPU.


This baby will be going back to eVGA if they allow a return.
...If not, anybody looking for a slightly used eVGA backplate?

The 580's new heatsink is far more capable than the 480's to the point that a backplate is no longer necessary.

On the 480s, those backplates DO help. But not on the 580s.

Wierd, if you have a fan blowing on the top it would help, my backplate most certainly helped, is the 580 backplate touch right where the GPU is with thermal padding(gel stuff)

The padding does touch around the GPU. I don't believe it was thermal though. Kinda resembled the same type of buffer padding that is usually on the underside of your motherboard with an aftermarket CPU cooler plate to protect the transistors from being crushed as you mount the hardware.

I was a bit shocked that temps raised 1 degree, but I tested twice on and off and it's a fact in my PC.
The backplate does give reinforcement to the keep the PCB from flexing, at least.

You know a 1° temp increase in ambient room temp could affect card temps.

Tested on, tested off, tested on, tested off. All within 45 mins or so. I'd say my results were strikingly consistent.


edit: And yes, I definitely notice a difference in PC component temps from ambient temps in changing weather. In this case, it's winter and freezing in my room. Sub 60F.

Does the 580 backplate use the 4 gpu mounting holes like the 480 backplate does?
If so, maybe during re/installation you may have broken the tim seal with the ihs.

It does have the 4 mounting holes. It was 1 degree cooler before installation, 1 degree hotter after installation, 1 degree cooler after un-installation, 1 degree hotter after re-installation, 1 degree cooler after uninstalling it again. Doesn't look like I broke the tim seal.

It's only a 1 degree difference, but I made the uneducated decision to buy the backplate for cooling. I was not aware it was for aesthetics.

Maybe you're not getting the same amount of torque with the bp installed.
