Question H55 enough to cool overclocked GTX 1080 with NZXT G12?

[PlymouthJoseph]

Hi guys,

My GPU (EVGA GTX 1080 Classified) is somewhat overheating with the normal heatsink (82°c gaming, 92°c+ synthetic) so I am going to be installing the NZXT G12 with a H55. Only thing I am worried about, is the H55 going to be enough to cool it?

At the moment, the GPU is overclocked and will hit 2050MHz while gaming and will struggle to keep 2000MHz while doing synthetic loads. My case (NZXT S340 Elite) has plenty of airflow (2x SP140 for intake and 2x AF120 for exhaust) with an ambient temperature of 25°c.

I plan on installing the radiator on the rear-exhaust of the case, but I am very worried it wont be enough cooling power to cool the GPU.
I am also worried about the VRMs and VRAM chips. I do plan on buying heatsinks for them, but I do not know what to get.
Also, is there any way I can keep the backplate installed? Really hoping I can...

If there is any more information you need, feel free to comment and I will get back ASAP.

Fair enough. Only thing then, would thermal pads be sticky enough to hold them?

Yeah should be if you get decent thermal tape. worked fine for me.

Thermal tape, okay. Do you know of any brands specifically that are pretty good?
I just want to make sure I have everything ready to purchase before I pull the trigger.

I dont recall the brand, might have been this:

Also, i made a guide back in 2014 when i first did it on a gtx 680. I just wouldnt recommend using the same heatsinks i used that time, they were heavy and hard to stick. Alu ones would be better.

Its really pretty easy
