Hello everybody,
 
My 980Ti Hybrid is reaching temperatures of 70°c - 73°c while playing graphically intensive things like FireStrike,Heaven,GTAV,Skyrim.
Without any overclock except for the factory OC EVGA applies.
Funny thing is I can push my 980Ti to 1525MHz stable without it affecting the temperature at all.
The Radiator is mounted in the front of the case, aproximately the same height as the Card.Pushing Air through it is a Corsair SP120 connected directly to the GPU.
The Case is sitting below a Desk.Ambient Temperature is between 20°c and 25°c I think, can't tell.
 
Such high temperatures are not normal for an EVGA 980Ti hybrid, are they?

I play on multi-monitor at 7680x1440 so every game I play is intensive.  Room temp is 72 or so.  52- 53 Celsius is the hottest that I have ever gotten on my hybrid.  Granted I am using push pull fans but that is good for a couple of Celsius.  
 
Make sure the fan on the radiator is spinning.  I have a feeling that the GPU core is not making proper contact with the heatsink. Before an RMA completely uninstall then reinstall all GPU software such as MSI Afterburner.    
 
Good luck.

Connecting the fans to the mainboard is no problem and working great with tools like Speedfan. Y-cable is also no problem.
70°C is high. I would also guess for not a propper contact between cooler and GPU. Other causes could be low pump or low fan speed.

Thanks I'll check once I'm home in a few days.
 
By acceptable do you mean acceptable for an overclock in that region or acceptable in general?
I know that 70°c won't harm the card in the slightest and I'm not sure if I'd rather have it RMA'd and propably get a lower clocking card or have it running at 70°c @ 1525MHz
 
By "not making proper contact with the heatsink" do you mean a faulty card or the thermal paste not being applied correctly/the cooler just not seated correctly?
 
While I'm at it: I'm interested in a push/pull configuration as well, do you use a Y splitter or do you have your fans connected to the mobo/fan hub?

By acceptable I meant in general but because you are using a hybrid it is high even with a moderate overclock. 

How much thermal compound should I use?
Just do a cross pattern?

I always spread my TIM. I tried the cross method, dot, lines, and always had bad coverage on the die itself. If I spread it, at least I know it is covered 100%.

JayzTwoCents YouTube just did a TIM video showing how much is too much.. He completely covered the die with an entire tube of paste and it was everywhere. It didnt change any of the Temps for the worse at all. They actually remained the same. I would never suggest doing that, as it is a massive waste, but as long as you use noncoductive/non capacitive TIM, you should be fine as long as you get good coverage.

Mx4 has been my go to for a couple of years now.

66°C is 150.8°F and is certain to cause burns.

If the radiator is as hot as you say then it is a good sign that it is removing the heat from the GPU chip. It is fairly easy to remove the shroud and check if the block is seated properly but all indications are that is is working as it should. If you decide to remove the pump/block assembly, I would recommend using MX-4 to reapply the TIM. I use MX-4 for everything and get excellent results.

Try plugging your fans into a motherboard header to increase their speed. That should help move more air through the radiator and lower your temps.

@Exidrial- did you replace the TIM yet? If not, do it! Also using MX-4 here, love it. If re-applying TIM doesn't work just open a ticket with EVGA and RMA if need be. 

Nope did not replace the TIM yet because my MX-4 is empty.Have to order a new one first.

Connecting the fan directly to the Motherboard didn't help.
I'm waiting for the MX-4 now.
 
My Pump is making this sound on idle with temps at 26°c:

Is that normal?

Mine has never made any buzzing sound like that...

I can hear it right now.I'm ~40cm away from it and the card is on idle.
