EVGA GTX 295 Backplate Performance Tested - 20C Temp Drop!!

[AuDioFreaK39]

I have some great news for you guys.

So I got my EVGA GTX 295 Plus cards today from Micro Center for $479 each. The backplates also arrived from EVGA in the mail, and I thought I'd give you guys the rundown on what kind of temperature differences you can expect with and without the backplate installed.


Without further adue, pics:



Hmm, wonder what's in the sunlit bag.

Here are some shots you don't normally see. For those who don't own an EVGA GTX 295, the shell is made out of hard rubber:

Inside of the heatsink:

Backplates:

As you can tell, the aluminum really is only 1mm thin as mentioned in the specs:

And now for the grand finale:


Idle Temperature WITHOUT backplate (stock speed) - 48/51C

Idle Temperature WITH backplate (stock speed) - 49/51C

Load Temperature WITHOUT backplate (stock speed) - 91/93C

Load Temperature WITH backplate (stock speed) - 70/63C

Let's recap:



Idle Temperatures

Without backplate - 48/51C
With backplate - 49/51C


Load Temperatures

Without backplate - 91/93C
With backplate - 70/63C




add to the fact that my Thermalright TRUE Copper is idling my Core i7 965 Extreme at 23C and this is a dream come true!

Nice setup! thanks for the pix too

Any word on EVGA releasing backplates for the 285?

No plans, its a GTX 295 exclusive.

 

[Fitseries3]

dammit... i want a backplate but evga is out of stock.

Too bad, well, was considering getting this baby for my card anyways:

They have a 295 version too, you should consider getting a couple of those if you want to cool your card even more!

 

[AuDioFreaK39]

My bad!

"Just a quick update to let you guys know that we are working on a backplate for the GTX 285 as well!"

 

[HolyCow02]

thats mighty impressive. Nice pics!

very "cool" thanks for the update and tell the guys at evga forums to stop being pricks.

They were being pricks? I know some of the guys over there. What were they saying?

Meh, I asked "what are temps like with the 295" because that would be the real deal breaker for me to step up, and I got horse shit answers:

You can't compare temps from one system to another, they would say.

then a mod told me I had to change my display name because if you rearrange the letters it can spell "Rapist"... sorry, my first initial is R, last name Paist. SORRY. Me do hate EVGA forums.

Without backplate is 10min run and with it is 3min, but the temps probably hit the max by then already?

I never looked into this, but anyone card to explain how replacing a rubber peice with holes in it with a metal peice with what looks to be the same size holes cools the card down? I keep looking at it and I'm missing it, very impressive something like that can drop card temps so drastically.

Wow, a 20c drop on both different cards just from applying a backplate. The cooler must not have very good contact with the gpus if adding a backplace helps. 20c is a lot, so I am guessing it has something to do with contact between the heatsink and the gpus.

 

[coodiggy]

It's a result of the backplate cooling the back of the gpu socket AND stiffening up the PCB slightly, giving a little more pressure on the GPU core slug. If you point an infrared thermometer on the back side of the GPU, you can measure a pretty high temp, same with most GPU's, backside cooling has been around for a while, but not everyone posts uber "how to cool your chips from both sides" guide. The holes may or may not be for asthetics, a flat surfice will not provide any turbulence, letting the air just slip past the hot bubble, the holes create turbulent flow for convective cooling?

My 8800 Ultra has a backplate, they used them on the SuperClocked editions. That made a massive difference.

A lot of heat accumulates on the back of the card. I mean think about it, we really are only cooling one side of our GPUs and CPUs.

 

[hat]

Yeah, and a 1mm thick sheet of metal is going to be able to cool 20c
I think it's much more likely that it has to do with the contact between the gpu and the heatsink.

It makes that much of a difference on my GTX280. I don't see why it wouldn't make that kind of change with the 295. Most of the heat is the GDDR3.

 

[AsRock]

Theirs one on the 2900XT and it helps a load. I ended up putting heat sinks on my back plate and it helped even more.

Shame they cannot make twin coolers for either side of the cards .. Well they could just that it be a problem for some like my self as i use the x1 slot which is for the sound card. I was running 2x2900XT coolers to do mine at one point when it was in another system.

Did anyone else notice that the OP is rich?

It doesn't really matter but yes, lucky him.

 

[wolf]

maaaaan 20 degrees!!! i want that backplate so bad, who wants to ship one to Aus for me?

Backplate does get hot, did some finger testing after I was running 3DMarks to see if my GTX 280 is stable. Didn't burn, but not something I'd like to keep my hand on =) But yeah, GTX 280 has 8 mem chips behind it as well.

 

[Nick89]

how can a back plate drop temps by 20C

 

[Binge]

The ram makes a lot of heat. You would get the same results with heatsinks on the back of the card.
