Stay humble and fight with good intentions friend.

I let my ego slip for sure, my apologies

Its not affecting it much - but it is affecting it.  The cooler the air in the equation, the lower the thermal equilibrium.

It's not warming the card, it's simply cooling it less. Not much less though, if anyone bothers to watch an actual test on it.

Cooling it less

 

Now that's kind of a funny way to put that its not helping the card run cooler by running hotter radiator air over it lol

so you're saying that the ambient air outside the case, passes through the rad, doesn't heat up? The rad is going to dump hot air into the case regardless of what my hand says, a cooler is only as effecient as the fin design and the fan performance combined with the ambient temp, the fans on that gpu are rotating air from within the case.... 

I dunno how this is hard to understand. The air exiting the radiator is still cooler than the GPU. You're still cooling the card, not heating it up. Any reasons for the card being hot is poor airflow throughout the case, or if the top of the card were too close to the side panel. It's not the second option from what I can tell, so it's the first.

"Hotter radiator air" will be assuming the air from the radiator is hotter than the GPU core, which it isn't. 

 

Though I would have figured someone who spends so much time and research on this subject would understand:

Guess not.

 

OP, increase your radiator + case fan speeds.

You:

t's not warming the card, it's simply cooling it less.

I dunno how this is hard to understand. (at this point you are getting hard to understand)

 

Me:

You do realize the GPU core causes the heat, but its the Heat Sink that is used to cool it.  But I know you know this already.  So we aren't cooling the GPU core.  You do know this right?  We are cooling the Heat Sink.  I know you know this. 

 

So yes this is an airflow issue - at this point I have to say DUH.  We cant keep saying that and expect anyone to be MORE right than anyone else.  We can argue the semantics of whose more right, but in the end if you want to be OPTIMAL, you don't have a front intake radiator.  What "works" is also right!  Its just not optimal.

 

Turn the heat up in your house to 100 degrees (or close all the vents but the room your in, you get where we are going with this yea?) and let your PC run as is for 24 hours.  Your PC idle temps will be higher than when the house is a nice 69-70 F of air intake.

The point of my response, which has been missed entirely it seems, is that simply putting a CPU radiator in front of a graphics card is not inherently going to cause it to run at 85c. The two factors at play which make it pretty irrelevant is air speed and the huge temperature difference between the gpu heat sink (and subsequently the core) and the air coming through a radiator. You still have a cooling effect whether you want to argue semantics on this or not.

 

If the OP is running their GPU fans at 100% to maintain those temperatures they have stagnant air in their case because the case fans are too slow. Increase those, problem is gone. Moving the radiator won't solve anything.

Agreed on the first paragraph to your points, but you cannot dismiss this until you test it out - that radiator is raising temps - and very well could be the culprit because (your second quoted paragraph)

 

100% agree they have stagnant air.  Because he has a neutral air pressure setup, on the more negative side - why - radiator intake is stifled unless running intense SP fans so its likely that his unimpeded exhaust fans are pulling harder than air is being pushed in.  But its more neutral than full negative because the equal amount of fans (and the reason he has these hot spots, 100% agree with you)

 

But if he top mounted the rad, allowing for cooler intake, with more positive airflow towards the lower back of the case (than the hotter restricted flow of a radiator intake - there is a difference unless some good SP fans of course) it could solve the problem right away without another purchase (maybe 1 120mm fan for front intake or whatever size) or cheaper purchase than just replacing a couple things.

Which is why I posted the video testing this theory in the first place. There's a very negligible difference if your fans are actually moving air through your system. SP fans will always be a bonus, but they shouldn't be required for this as far as I'm aware? If the fans currently in the system are running faster than idle that is. At the very least you wouldn't be running your GPU fans at 100% (and I know those EVGA cards can cool far below 100%).

The performance difference is huge, but dBA higher, on SP fans versus AF or regular fans on a radiator (reg fans throw air around in a cone, SP fans punch air in a straight line out -forced through a rad- basically) so if he doesn't have SP fans on that rad he is really hurting his intake capabilities something fierce - I have run regular fans on an AIO to test, temps are only a few degree C higher but the amount of air being moved is completely different - id say 100% delta between the two (in push, or pull or push/pull very similar results)  - SP fans typically have a MUCH higher RPM allowance as well which equates to usually a 100% increase in the dBA levels between the two.  Cant deny he has one hell of a hotspot (why I don't like those cosmetic cases, I have a HAF and a cosmetic case I test in...the difference is night and day in the temps you can achieve with the same hardware)

I wasn't sure about the difference, but I know there definitely is one. If OP jacking up their case fans doesn't solve the problem, SPs are needed for sure.

So I ran up the rpm on fans on my AIO 

Also switched it from a push air thrue radiator to pull air thrue radiator so now its behind the radiator temps highest I get is 71c on my gpu with gpu fan speed running at 75%. Insted of 100%

What fan speeds is your AIO at? if your cpu is chilling at 50-60c doing a not cpu intensive game, the fans will be barely spinning. Set them to 800-1200 rpm, and see new temps.

I did what you said an bam gpu running max at 71c highest with only 75% fan speed insted of 100%. I also switched from fans in front of the rad put them in the back to pull air. Insted of push

Nice! always fun to experiment with different configurations!

Also, you can hook up the bottom fan on the aio (the one next to the GPU) to a motherboard fan header, and set it to always be above 800rpm (800 is usually silent), and if the GPU gets hot, the fan spins faster.

Sounds normal. Lack of airflow and open air cooler equals high temps.
