RTX 2070 XC Ultra NZXT G12 questions

So I'd appreciate some answers to some questions I have if possible. See my rig specs below.
I am so over the noise of the XC Ultra cooler. I ordered the G12 should be here in a week hopefully and watched countless videos of installs etc. Please, yes I am aware the card vrms dont get cooled on one side blah blah blah. For reference with stock cooler I get about 30-40c idle depending on the temp for the day and 65-70c load with 100% jet engine fan with a +95mhz oc and +799 on vram resulting in 2040mhz. On to my questions:


1. Is it worth $15-$25 replacing the g12 stock fan with a noctua?


2. From what I have seen the Back and Front plates can be left on, my theory is this can act as EVGA intended heat sink for the vrm blaha blah blah comment above, I was thinking of strapping another fan on or getting a pci fan bracket near the side with no fan. Or better to take the plates off and not over think it?


3. Does anyone know if there is an adapter for the "newer fan connection" on the card anywhere to buy. The XC ultra has the same connector as the FE. No longer can use those Gelid vga to 4pin adapters people have.


4. So looking for Asetek coolers. I am leaning towards EVGA CLC240 for $99, I have some extra Noctua fans already so I will be slapping those on. I was also thinking Kraken x53 or whatever it is called for $129 ( I also heard that they do not come with AM4 bracket?) if I can get it for $99. Or any $99 or less 240mm Asetek cooler for that matter. I am also thinking if down the road I may use it as a CPU cooler so I would prefer to stay away from single fan coolers.


5. If anyone could comment on pump speed settings etc.


Thanks!

the VRM needs a heatsink, if you take them off then you need to add a replacement.



you can leave your front plate on, it'll cool your vRAM fine.

the silver/white part cools your VRM and it looks like it's secured by the stock heatsink (assuming the heatsink screws in on the 6 holes on the edge), so if you swap the heatsink you'll need to take it off and find a way to cool the mosfets that are underneath. the G12 should come with either thermal tape or thermal epoxy/adhesive (never bought a G12 but my Raijentek Morpheus did) but if it doesn't then you need to buy some.

you don't need to replace the fan unless you want to, they wouldn't include it if it was inadequate.

can't help you with a fan adapter, I used a cheap $4 cable on Amazon for my 1080 TI but it was normal 4-pin mini-PWM.

I would:
  1. not do it as you could as well buy a 2080/Super instead with that much extra money
  2. leave all heatsinks on the card, if some are in the way of the cooling plate of water cooler, well cut the offending parts away
  3. you don't need to replace fans duh, noctua is overhyped and overpriced too
  4. you can control fans on your mobo with GPU temperature as source, make your own curve etc. look for Speedfan or similar software
  5. not buy cards with proprietary connectors if I plan to mod them and if I had to well, snip snip, chop off the old connector and hook up what ever fans I want to it, screw RGB off with that FAD

Thanks for your re.


Evga actually designed the heatsink to be super easy to service the card. Only held on by the 4 screws around the gpu. Only 2 points of contact: GPU and that thermal pad, thats it. The vrm arent even getting direct air with the stock cooler, only air that makes it through the fins and even then the vrms are under the plate which like you said is acting as the heatsink for the vrm and mem.



That stock thermal pad is probably doing very little although is there to transfer some of that heat to the fins.



After looking at that pic and reading your post, I think the G12 will actually do a better job at cooling those vrms with direct air pushing on it. It doesnt have to go through fins as the stock cooler does. Also I will leave both plates on. I will remove the pad and let the direct air hit it, I may add some low profile copper sinks to that strip if I have the clearance.



Yeah about the G12 fan, I am sure it is capable but thinking Noctua might be quieter, generally saying they are more efficient. Guess I'll cross that bridge when I get to it.


Gonna see if I can take apart that stock heatsink, maybe I can poach that fan connector from it.
